The Redflow Zinc-Bromine Module (ZBM) is the smallest commercially available hybrid zinc-bromine flow battery in the world. The size of these 10kWh energy storage modules means they can be deployed in applications, such as telco tower sites, that were previously impossible to address with flow batteries, yet they can also scale to grid-level energy storage.ABOUT SIMON

SOLVED: INSTALLING WINDOWS 10 USING BOOTCAMP ON IMAC WITH AFUSION DRIVE
Posted on July 29, 2019by simonhackett
_Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the numerous idiot lights which plague the modern driver. Rather, if the driver makes any mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver”, he says, “will usually know what’s wrong.”_ _(Source: BSD Unix Fortune Program)_ I recently managed to install a current Windows 10 distribution onto an older iMac that I had in storage. I wanted to set up this machine to run some specific Windows software for which it was well suited, and that let me make good use of an otherwise idle machine. The iMac has a then-fastest-around 2.9Ghz CPU and features the (then) latest and greatest storage innovation, the ‘Fusion Drive’. This is a small SSD blended with a 1Tb Hard Drive. The Fusion Drive was designed to leverage fast-but-expensive SSD’s with slow-but-cheap hard drives, before SSD’s got so cheap that the hard drive becamealmost irrelevant.
My intention was install Windows 10 using Bootcamp, with an arbitrary 50/50 split of the 1.1Tb Fusion Drive. At the start of the fateful weekend concerned, I recall thinking ‘how hard can this be?’ because I’d installed Windows using Bootcamp on my current-generation MacBook Pro (with a big SSD) withzero issues at all.
Turns out the answer is: ‘Very Hard’. I had to get past multiple ‘I should give up because there is no apparent way around this, and the error message gives me no help at all’ situations, spread across what became an entire weekend of trial-and-effort and repeated fruitless attempts at things that took ages, punctuated with just enough ‘ah hah’ moments and clues found via Google to keep me doing it…! I didn’t find the entire list of challenges I faced in any single web site, so I have decided to write my discoveries down here, in an ‘integrated’ manner. Each of these issues represents some hours of repeated head-banging attempts to get past it that I hope to save you, dear reader, from repeating. I am assuming in the below that you know how to do a Windows installation using Bootcamp (or are prepared to work that out elsewhere). This isn’t a guide to doing that – its a guide to why the process failed – and failed, and failed, and failed – for me. Each item below starts with a headline that frames the fix – so if you mostly just want to get it done – just dance across those headlines for a fast path to a working result. YOU _REALLY_ NEED TO BE RUNNING MOJAVE (MAC OS X 10.14) I fired up Bootcamp under the OS on the machine at the time – Mac OX 10.13 – and it said it could install windows 7 or later. Well, I wanted to install the latest release of Windows 10, and that’s‘later’, right?
Wrong.
On this model of Mac you need to use an appropriately large (16GB or more) USB stick. Bootcamp writes the Windows 10 install ISO you’ve downloaded by now (you have, right?) onto that USB stick and turns that into a bootable Windows install drive (including throwing the ‘Bootcamp’ driver set onto it, to be installed into the Windows image once the base install is done). Well, I plugged in a 16Gb USB stick (actually, I tried several sticks ranging from 8Gb to 32Gb, fruitlessly). In each case, after scratching around for ages, Bootcamp failed with an error message say that my USB stick wasn’t large enough. Some Google searching turned up the key information here – that Windows 10’s recent ISO’s are large enough that they cross an internal 4GB size boundary that in turn leads to Bootcamp not being able to cope with it properly. The answer looked to be easy – upgrade to Mojave. Ok, annoying but straightforward. Cue the download and install process, and come back in several hours… YOU ALSO NEED TO UPDATE MOJAVE TO THE _VERY LATEST VERSION_ Turns out that the build of Mojave one downloads from the App Store isn’t the very latest version (Why _isn’t_ the very latest version? Beats me!). Bootcamp on the base release of Mojave says it can install Windows 10 or later (not ‘Windows 7 or later’). Yay – that suggests the bug has been sorted out – after all, it mentions Windows 10! Sorry, but no. Same failure mode, after the same long delay to findout. Argh!
More Googling – turns out the bug didn’t get triggered until some very recent Windows 10 builds, and the base Mojave build still had that (latent) bug when it was released. Next step is, thus, a Mac OS update pass to move up to the very latest Mojave build, including a version of Bootcamp with the issue resolved in it. This is in fact documented on the Apple support site(if you own 20:20
hindsight).
YOU MAY NEED TO BACK UP, WIPE AND RESTORE YOUR ENTIRE MAC OS DRIVE BEFORE BOOTCAMP’S PARTITIONING PHASE WILL SUCCEED This one was painful. After Bootcamp managed to set up my USB stick properly, and managed to download and copy on the Bootcamp windows drivers in as well, it then failed to partition the drive successfully (the last step before it triggers the Windows installation to commence). As usual, the error message was useless: _Your disk could not be partitioned ; An error occurred while partitioning the disk. Please run Disk Utility to check and fix theerror._
The problem here is that I _did_ run Disk Utility to check and fix the error, and no error was fixed! The Disk First Aid run came up clean – said my disk was fine. I tried booting from “Recovery Mode” and running Disk First Aid again – nope, still no error found or fixed. Time to dive deeper – open up the display of detailed information (the little triangle that can be used to pop a window of debug text) during the underlying fsck… …One tiny clue turns up – a succession of warnings in the midst of the checking process, a warning (not a failure) involving something about ‘overflows’. Turns out that Disk First Aid (‘fsck’, really), within Disk Utility doesn’t fix these issues – it just declares the disk to be ok and finishes happily despite them. Disk Utility can even partition the drive just fine – but the Partition function in Bootcamp itself … fails. The fix turns out to be annoyingly radical: Do a full system backup, and then do a full system restore. So – break out a spare USB hard drive to direct-connect (less angst and potentially higher I/O rate than doing it over the network). Use Time Machine to back up the whole machine to that local storage, then boot in recovery mode and restore the system from that drive again. This takes… along time. All day and half the night. However – it helped! When I tried yet once more, after this radical step… now the Bootcamp partition step works – hazzah! And then Windows 10 starts to install itself at last – hazzah! IN THE WINDOWS INSTALLER, YOU MAY NEED TO FORMAT THE PARTITION DESIGNATED FOR WINDOWS Once windows starts to install process, it reaches a point where it displays all drive partitions and asks you to just pick the one to install Windows onto. Merely selecting the right partition (the one helpfully labelled BOOTCAMP) doesn’t work. It fails, saying the partition is in thewrong format.
It seems that some inexplicable reason Bootcamp has left the intended Windows partition in the wrong state as far as the Windows installeris concerned.
The fix is to bravely select the partition concerned (again: its helpfully labelled BOOTCAMP)… and hit the ‘Format’ button to reformat it. Then you can re-select it – and the installation now starts to work – yay! USE A DIRECTLY ATTACHED USB KEYBOARD WHEN THE WIRELESS APPLE KEYBOARDSTOPS WORKING
This one is self-explanatory. My Apple wireless keyboard didn’t workin Windows.
I thought I’d just need to load the Bootcamp drivers to fix that but – not so fast! (see the next issue, below). Meantime I just switched to a wired keyboard – ironically the one I found in my storage room was a genuine Microsoft branded one with lots of useful extra function keys on it. I’ve been perfectly happy to just stay with that – especially noting the next issue. REMOVE/RENAME A MAGIC DRIVER FILE TO AVOID BOOTCAMP SUPPORT CAUSING A WINDOWS “WDF VIOLATION” BLUE-SCREEN-OF-DEATH A MINUTE OR SO AFTERWINDOWS BOOTS
Well, with Windows ‘up’, I installed the Bootcamp mac hardware support drivers. This is important for all sorts of reasons (including WiFi not working until you do). I did that by selecting the (still mounted/attached) USB installer stick and running ‘Setup’. The installation of drivers worked fine. What didn’t come out fine was the unintended consequence. Once the Bootcamp hardware support was installed, Windows started crashing a minute or so after each boot up, with a “WDFViolation”.
You can log in and start working – just – and then ‘bang!’ –sad/dead windows:
After everything else (and one and a half days of this stuff) – this was _really_ frustrating. Cue yet more googling – and at least this one seemed to be an ‘understood’ issue. It appears to the the case that the wrong version of a crucial driver file (keyboard support related, by the looks of it) is loaded in by Bootcamp, but when installing onto this _particular_ generation ofiMacs.
Yay.
The fix – after I found it – involves booting Windows in diagnostic mode and disabling that driver file. Even getting into that diagnostic mode is a challenge… it turns out that you don’t reboot holding down the shift key for ‘safe mode’ in Windows any more – that would too easy… …Instead, now you boot up and then select restart… and while doing that _restart_, you hold down the shift key. You then wind up with the opportunity, during the reboot, to access diagnostic functions. Sure, that’s obvious… not. Anyway – once booted in diagnostic mode, select to bring up a ‘DOS’ command window. Now select drive C: and then locate and rename (or delete) the errant driver file concerned (C:\Windows\System32\Drivers\MACHALDRIVER.SYS) as per this screen shot: One trap to watch out for: Make sure you’ve changed to drive C:, and that you’re not still on drive ‘X:’ looking for that file. That drive – which you start out on when bringing up the command window – contains a whole separate copy of Windows…without the bootcamp files on it. So you think you’re searching in the right filesystem – after all, Windows is on it… but you aren’t. I guess that’s a consequence of using the Diagnostic mode, but it fooled me for a while, as I was trying to find the errant driver file _there_ (on drive ‘X:’) at first…and failing to do so. Now reboot and – yay – no more WDF blue-screen-of-death failures. … but also, no bluetooth keyboard support. No problem to me – I really prefer the direct-attach larger keyboard I found with all the Microsoft specific buttons on it anyway,for this task.
Contrary to warnings on the web sites that had helpfully pointed out the incorrect/broken MACHALDRIVER.SYS file issue, I have had no practical issues with volume control or similar things as a consequence of disabling that file. For me, it all seems to work fine without this file in my life at all.SUCCESS!
At this point, I have a working Windows 10 installation on my machine. I have subsequently installed the software I wanted to run in the first place and its all working just fine. I do hope someone else finds this useful – and that if you do go down this road, that you have a smoother ride than I did! Posted in macintosh , windows | Tagged bootcamp, fusion drive

of John Lindsay as a non-executive director of Redflow Limited. John has deep skills and experience around technology and technology related business matters. He is, to use a favourite phase (for us both), ‘smart and gets things done’. Its worth appreciating that John has specific expertise and experience in precisely the realms that Redflow needs. I sent John over to Brisbane when I originally invested in Redflow, to help me assess the technical merit of the technology. He, like me, has been a shareholder in Redflow ever since. In addition to being a great businessman, John is also a technology geek at heart (as am I). He has been an active member of the electric vehicle and renewable energy community for many years. His daily driver is electric (as is mine) – of course. He knows which end of a soldering iron is the hot end. His idea of a fun weekend hobby is (literally – and recently) to have set up a D.I.Y. solar and battery offgrid system in his own garage to charge up his electric car from renewable energy because… he can (and because _he knows how to_). His appointment frees me up to transition my own head space in the Redflow context totally into the technology around making our battery work in the real world. Doing that stuff is what I _really_ love about being involved with Redflow. I love helping to make this amazing technology sing and dance smoothly for real people, solving realproblems.
It was just the same at Internode – the company I spent more than two decades running. The ideal situation is to do things in business because you’re passionate about it. In the words of Simon Sinek: People don’t buy what you do, they buy whyyou do it
.
I care about Redflow because I believe that Redflow’s technology can genuinely help to accelerate the world’s transition to renewable energy as a replacement to burning things to make electricity. Its really that simple. The technical lever I designed, to help Redflow to move this particular part of the world, is the Redflow Battery Management System (BMS) . I am very proud of the great work done by the technical team at Redflow who have taken many good ideas and turned them into great code – and who continue to do that on an ongoing basis. So… while there can be a natural tendency, when looking at this sort of transition, to wonder whether my leaving the board (given how influential I’ve been at board level in the last few years) is because something ‘bad’ is happening, or because I don’t like it any more, or because I don’t feel confident about things at Redflow, the reality is _precisely the opposite_. My being happy to step back from board level involvement over the next few months is the best possible compliment that I can give to the current board, lead by Brett Johnson (and now including John) and to the current executive (now ably lead by Tim Harris). I’ve put my money where my mouth is, to a very large extent, with Redflow. I am its largest single investor – and I have also put my money down as a customer, too, in my homeand in my office
.
At this point, I’m happy to note that we are seeing great new batteries turning up from our new factory. We are on the verge of refreshing our training processes to show our integrators – and their customers – how far the BMS and our integration technology has come at this point (and just how easy it all is, now, to make the pieces work). We are looking forward to the integration industry installing more of our batteries into real world situations around the world again – at last. We do this with confidence and we do this with eagerness. I am proud to be a shareholder in Redflow and I look forward to the next chapter of this story. Posted in batteries ,energy , internode

THE ROLE OF FLOW BATTERIES IN DISPATCHABLE RENEWABLE ENERGY GRIDS Posted on May 27, 2018by simonhackett
At the Australian Energy Storage conference held in Adelaide, South Australia on May 23-24 2018, I delivered this keynote address about the role of flow batteries and other energy storage technologies in the context of building an energy grid with renewable energy in the majority and with “Baseload” generation on the wane. The core thematic question I posed was this: Is a future grid with large amounts of renewable energy storage necessarily using Lithium-Ion (or other, otherwise conventional) battery systems for the majority of that large scale energy storage – or are there betterways?
A specific underlying aspect of that conversation is about environmental impact – around the notion of ‘environmentally friendly’ energy generation and storage being a notion that must factor in the ultimate environmental impact for each storage technology and not just its up-front cost. The video below is a recording of my address synchronised to the slidedeck that I used.

HOW REDFLOW BATTERIES WORK Posted on February 1, 2018by
simonhackett
I often get asked to explain how Redflow ZBM2 flow batteries work – compared to conventional batteries – and how batteries fit into your life in a home situation. An interview I did a while back with the delightful Robert Llewellynexplains those
things.
So… If that’s a subject you’re curious about, and you’d like to spend 15 minutes learning the answers… this Fully Charged show about Redflow ZBM2 flow batteriesexplains it !

THE BASE64 REDFLOW ENERGY SYSTEM Posted on February 1, 2018by simonhackett
_Updated Feb 2019: System now operating at full battery capacity and with increased solar array size_ The Base64 energy system has been a fantastic learning experience for us in general and me in particular. The system is built around a large Redflow ZBM2 battery array. We call these configurations an “LSB” (Large Scale Battery). It is charged with solar energy harvested from a large solar array (most of which is ‘floating’ above the staff carpark). We deployed it first some time ago now, prior to having got so deeply experienced with using Victron Energy inverter/charger systems. At the time we (Base64) purchased a big custom industrial AC inverter that didn’t come with any sort of monitoring or logging system and no control system to drive it to interact properly with on-site solar. All of the necessary energy system control, management and data logging technology comes ‘out of the box’ with the Victron Energy CCGX controller unit in a Victron installation, so I imagined ‘everyone’ provided such things. Well, I was wrong about that. The big industrial unit we bought came with nothing but a MODBUS programming manual and created a lot of head-scratching along the lines of… ‘now what?’. For some reason industrial scale systems are in the dark ages in terms of the stuff that Victron Energy have ‘nailed’ for the residential/SOHO battery market – they supply great, easy to use, easy to understand, effective and powerful out-of-the-box energy system control software and hardware (entered around their CCGX/Venus system). It also comes with an excellent (no extra cost) web-accessible portal for remote data logging, analysis and remote site system control. Meantime, we were exercising our large battery ‘manually’ – charging and discharging it happily on a timed basis to prove it worked – but we were unable to run it in a manner that properly integrated it with the building energy use, for the lack of that control system in the inverter we had at the time. We didn’t want to write one from scratch just for us – that’d be a bit mad. We also didn’t want to pay someone else thousands of dollars to set up a third party control system and make it work – a major consulting project – just to do what the Victron Energy CCGX does on a plug-and-play basis at very low cost. In parallel, and importantly – it also took ages to get substantial on-site solar operating at Base64 – and there wasn’t much point in driving the LSB in production until we did have a decent amount of on-site solar to sustainably charge it with. To the latter point – we are in an massively renovated and reworked heritage listed building and I was unable to get permission to mount solar on the massive north-facing roof of the main building. Instead we commissioned a rather innovative mounting system that has (at last) let us complete the installation of a 50kWp solar array that literally ‘floats’ above our staff car park on four big mount poles supporting what we call ‘trees’ – suspended metal arrays holding the solar panels up. That system was commissioned and imported from a company called P2P Perpetual Power in California to suit our site. There are lower cost systems – but (by comparison) they’re ugly. We wanted it to be beautiful, as well as functional – because Base64 in all other respects is…both of those things. It was worth the wait. The result is (in my humble opinion) quite spectacular. Including that ‘floating’ 50kWp array, we have a total of 99kWp of solar on the site, though some of the rest of it is on ‘non-optimal’ roof directions, and so on a good day what we see around 80kW generated at peak in the high (solar) season. That said, the advantage of some other parts of the solar system being on east and west facing rooftops is that our solar generation curve runs for more hours of the day. We get power made from earlier in the day (from the eastern array) and later into the evening (from the western one) – and that’s quite helpful in terms of providing a solar energy generation offset to local demand patterns. In parallel, we pulled the LSB apart and rebuilt it using Victron Energy products and control systems, so that we could get a fantastic operational result and have optimal use of the solar energy to drive the building, charge the batteries, and support the building load at night – the very same stuff we do in houses with our batteries, just on a bigger scale – without facing a one-off software development exercise for the old proprietary inverter system we had been using. Swapping the Victron Energy gear in has turned out cheaper and far better than the bespoke software exercise would have ever been. It has also created a signature example of a large scale Victron Energy deployment running a decently sized multiple building site. I hope that this, in turn, may inspire more of the global Victron Energy installation community to consider the use Redflow battery technology at this sort of scale. The battery array is built with 45 x ZBM2 = 450kWh of Redflow energystorage.
We have 72kWp of Victron inverters installed right into the container as well. We could have gone larger (in terms of peak inverter power), but these have been ‘right-sized’ to the building demand at Base64, with summer peaks normally around 60kW (75-80kW worst case) and typical draw around the 30-40kW level when the building complex is in daytime operation. It is all linked to that 99kW distributed solar array using via multiple Fronius AC solar inverters. I’m thrilled with how well the system is working – its a monument to all of our Redflow BMS development work that the whole thing – at this scale – really is ‘plug and play’ with the Victron CCGX energy system controller and the associated inverter/chargerequipment.
It is very satisfying to run an office in the middle of a major city that typically uses very little grid energy, that is resilient to grid faults, and that even still exports solar energy to the grid as well. A subsequent step will be to interface with a grid energy ‘virtual power plant’ operator in the future, so that we can sell battery energy back to the grid during times of high grid demand. Every battery system on an energy grid has the potential to also become a programmable grid-supporting energy source during peak load periods. The missing links are software, regulation, and attitude – with the software part being the easiest of the three. We can easily set up to proactively control over when the battery charges and discharges in response to, for instance, wholesale market price. The Victron control system makes that easy. What need to give that project legs is an innovative retailer who will work with us on that and a small amount of software ‘glue’ to make it happen onour local site.
Here is a little gallery of photos of the system that we’ve installed – click through them for a little more information aboutthe system.

INTERNODE NBN HFC USING AN APPLE AIRPORT EXTREME AS THE SITE ROUTER Posted on December 31, 2017by simonhackett
I installed an Internode NBN HFC service in an apartment a few months ago. It comes with a Huawei HG659 router, attached to the NBN standard issue Arris HFC cable modem. I really don’t like that router. Its got some negative characteristics – including it having a DHCP server that can get itself confused and conspire to keep handing out a conflicting IP address on the active network. I also much prefer using Apple Airport Extreme base stations for WiFi networking rather than the built in stuff in routers of that ilk (lets call them ‘low cost and cheerful’) – especially when I’m running multiple WiFi base stations (as is the case in the site concerned). I’ve had great success in another site using Internode NBN via Fixed Wireless by just configuring the PPPoE client into the Airport Extreme and plugging that straight into the incoming connection from the Fixed Wireless NTD. That worked like a charm, and eliminated a similarly ‘cheerful’ router in that circumstance. However this simple approach just didn’t work on the NBN HFC connection – configuring the PPPoE client in the Airport Extreme and plugging it into the Arris HFC cable modem directly lead to no joy. Each NBN ISP has some choice over how the HFC based NBN connection gets deployed to their customers. Some digging turned up the data point that the Internode service delivered via the NBN-Arris HFC modem is implemented as two ethernet VLANs, with VLAN 1 delivering the bundled VoIP fixed line phone service and with the Internet service delivered over VLAN 2. There is no way to configure the use of an upstream VLAN in the Airport Extreme – it expects the PPPoE frames to turn up natively (with no VLAN tagging). Some more digging and the solution emerged, namely to keep the Huawei HG659 in the picture but use it merely as an ethernet VLAN decoder. In that role, its job is so simple that it can do it without losing theplot.
and… it works (yay!)… but there are – of course – wrinkles The steps involved _should_ have been this simple: * Configure the HG659 using its wizard to ‘connect with another modem’. This is what the HG659 uses as its description for bridging the incoming VLAN to the local LAN ports. * Keep the HG659 WAN port connected to the Arris HFC modem(obviously)
* Cable the Airport Extreme WAN port into one of the LAN ports ofthe HG659
* Using the Airport Utility on a Mac, configure your PPPoE account details into the Extreme (Internet tab, select PPPoE and then fill in the username and password, leave the ‘Service Name’ blank) However, this is what I _also_ had to do (all in the AirportUtility)…
* The DHCP IP range configured into the Airport Extreme needed to be changed (at least, I needed to change it, to make things work – YMMV). I switched it
from its default of the 10.x range, and instead set it to use NAT on the 172.16 range (Network tab, Network Options button, IP v4 DHCPRange drop-down)
* I had to turn off IPv6 entirely to avoid an ‘IPv6 Relay’ error coming up (Internet tab, Internet Options button, Configure IPv6 drop-down set to ‘Link Local Only’). * Turn off ‘Setup over WAN’ to avoid an alert coming up on the Airport Utility and the base station light flashing amber (Base Station Tab, clear the “Allow Setup over WAN’ check box). The point here is to explicitly disable the capacity for the Airport Extreme to be accessed (by the Airport Utility) over the WAN path. That’s definitely something I _want_ disabled. My only issue here is that I’m surprised this checkbox is actually on by default in thefirst place!
One more bit of collateral damage here is that I probably can’t access the free VoIP phone service delivered over HFC VLAN 1 and out via the analog port on the HG659. I don’t care, I wasn’t interested in using it in the first place. It may well be the case that some cunning manual configuration of the HG659 could make that work (too) – but I _really_ don’t care about it – so I justhaven’t tried.
The one silly thing left out of all of this is that I didn’t get rid of any physical devices in the process, so I have this conga line of three hardware devices between the cable modem wall plate and the user devices in the site – the Arris HFC modem, the HG659 (now as a VLAN 2 decoder box only) and the Airport Extreme (as the site router plus central ethernet switch to some downstream Airport devices). Speed tests are just as good as they were already, with downstream rates testing reliably in the mid 90’s and upstream in the high 30’s – pretty darned good (especially through that crazy hardware conga line) on a 100/40 Internode connection. Importantly the issues I had with the HG659 router and DHCP are gone.Other notes:
* The Internode NBN HFC service is in fact deployed on TPG infrastructure, so the above should apply equally to a ‘native’ TPG NBN service too. This also explains why the IPv6 doesn’t work(sniff).
* The VoIP service should be capable of still being used, perhaps with some custom configuration of the HG659, and I may try to find a way to make that work just for the sake of the challenge * A router such as a FritzBox which is capable of VLAN decoding on the WAN port should be able to be used to deliver the Internet service directly via the Arris HFC modem without using the HG650 at all (eliminating one device). Its also _possible_ the FritzBox may be smart enough to support logging in to the voice service via WAN VLAN 1 as well … and that is something to try out another day…!Arris HFC Modem
Huawei HG659
Apple Airport Extreme ------------------------- POSTSCRIPT: There is another approach to the removal of the Huawei device from the critical path that has been pointed out to me on another blog – here.
This won’t work with the Airport but it _is_ a way to allow a Fritzbox or a high end Billion or another router with WAN port VLAN support to be used for the Internet path instead of the HG659, leaving the HG659 functional as well – in parallel – to provide the voice port service that is bundled in with the Internode NBN HFC service. The benefit here is for people who do want to use that bundled voice service while also removing the HG659 from the critical path in Internet access terms. While it does need yet more hardware (an ethernet switch) – its a really creative and effective answer that might be very helpful to others to know about!

REDFLOW ZBM2 DEPLOYMENT AT BOSCO PRINTED CIRCUITS Posted on August 17, 2017by simonhackett
A CASE STUDY IN COMPLEX ENERGY SYSTEM OPTIMISATION Bosco Printed Circuits is the largest maker of Printed Circuit Boards (PCB’s) in South Africa. The production line at Bosco needs a lot of energy. The direct and indirect consequences of losing energy supply to the line are substantial. Johannesburg, where Bosco are based, has significant issues with energy supply – both in terms of reliability and also (as a consequence) in terms of energy cost. Like most businesses, Bosco already had an extensive solar array installation, which certainly helps with the economics of energy supply. The solar array is not sufficiently effective, is isolation, to address the complex challenges for the business in terms of supply cost and supply security. Energy supply to Bosco from the grid utility is time-of-day based. The energy supply cost is very high during distinct morning and evening peak periods, to discourage energy use in those times. These peak time bands are periods of high energy requirement for Bosco. The are the times when the potential for grid failure is greatest and are also the periods when the _consequences_ of grid failure for Bosco are the mostsevere.
Of course, these times (early morning, late afternoon) are also exactly the periods when the solar arrays can’t help, as they are outside of the solar peak generation periods. Grid outages are expensive for Bosco. Not only do they result in lost productivity, but they also have further economic consequences in terms of partially produced PCB’s having to be scrapped when the production machines are halted without warning.THE CHALLENGE
Bosco had a variety of business aims and objectives across their daily operating cycle that their energy system had to address: * To ride over transient periods of grid loss seamlessly usingbattery energy
* To support the operation of the production line for an extended period (hours, not merely minutes) in the face of longer periods of grid outage, so that the company can keep working, using battery energy augmented with any available solar energy, for as long aspossible.
* In cases of a very extended grid outage (several hours), to allow the production line to be closed down with plenty of warning (at least an hour) from the point at which the shutdown decision is made. * To time-shift energy obtained from the low cost overnight off-peak period into the morning peak period (0600-0800), prioritising battery energy usage at this time in order to minimise the use of very expensive grid energy. * To also minimise afternoon peak-period grid usage by again prioritising the use of battery energy in this second daily period * To use the residual battery energy, harvested from overnight off-peak charging and from any excess of daytime solar power, to supply the background energy needs of the building into the evening. * To recharge the battery array again using off-peak power from midnight to 6am ready to commence the next daily cycle. This need set required a battery energy system capable of consistent hard work and capable of daily 100% energy discharge, working in a hot environment, and without loss of output capacity over time.THE SOLUTION
The solution uses 14 x Redflow ZBM2 batteries (140kWh) interfaced to a large array of Victron Energy inverter/chargers and a large solararray.
The system orchestrates this complex daily cycle of energy optimisation using the Victron CCGX and the Redflow BMS, to achieve the aims and objectives noted above. Here’s a typical day in the life of this system, in terms of the sources of energy to run the plant: Bosco Printed Circuits Energy Consumption You can see the periods where the battery system energy (blue) is prioritised in order to minimise the use of grid energy during peak times. You can see the battery being fully utilised to supply energy during the afternoon and evening as the solar consumption falls away, and you can see the system recharging using off-peak energy again from midnight, ready for the following day.
