The best project implementation I have ever seen! We only ever install Fronius inverters with byd batteries. But for this, the complete 10kWp system is also ready within one day. ( Including the panels ) 👍😎
Andy's area of Australia has been suffering very heavy rain and flooding. Hoping Andy hasn't been badly affected and I wish the best for his family and neighbors.
Yes, that was in our are. We've been cut off since Friday. The water is gone now but no internet. All good so far, some minor water in the garage but all dried out again. PowerWall is running 💪
You have done a fantastic job pulling your power wall together. It looks great 👍 . We are now in the 1st of March and am looking forward to many more of your post. You deserve an award 🥇.🏆
@@garysmith2104 thank you but there is nothing we can do. I managed to upload one 7.5GB large video today by using a guest wi-fi of a company in town. So this will come tomorrow 😀
Your videos are a joy to watch the choice of music and video editing is very good! I think that you are one of the best in technology videos! Hope you still continue making videos, you'll find a project to show us. Thank you for having the trouble of videoing and showing us. If you wouldn't have done that then you would have already two powerwall systems made.
Thank you. Me too, it was a very interesting project indeed. A lot of work... a lot... hundreds of hours. But I quite like the challenges coming with such a system. You never know how things turn out and what to improvise.
Danke Dir, ja, alles gut soweit. Das Wasser ist wieder weg, kommt aber jeden Tage wieder wenn es wieder regnet. Es hoert einfach nicht auf, der Boden ist voll wie ein Schwamm und das Wasser laeuft einfach ab.
Incredible upgraded DIY wall system and powered up for the first time . I know you’re happy . Like the idea solution about the bending inverter power cables . Top knotch .
Thx for your perfect videos….. I like them very much because I shall begin my „off Grid Garage“ next month….. so as a retired (1 month ago) electrician engineer I need an interesting project….. so thx for the inspiration Greetings from Germany 🇩🇪 Ben
what my system was meant to look like ... smiles .. fantastic effort and job well done .. not much sun last few days tho .. cooled done wee bit .. and the crows cawing in the back ground with the kookaburras are whistle clean .. congrats .. have a beer and watch those data logs .. cheers
honnêtement c'est TOP TOP cet investissement est superbe et ce sera une batterie modèle sur UA-cam ! effectivement ANDY aucune chaine ne fait ce que ta chaine fait 😉 BRAVO.
Andy, that disconnect switch is the same one I had trouble with about 4 years ago on a boat. I ended up just putting a direct line to 400 amp slow blow and no disconnect but installed a clip to hold a cable cutter for emergency disconnect LOL! Measure the voltage loss across the switch. Replaced my switch twice. Yes is was in a marine environment but only fresh water. Most disconnect switches suck!
I have been watching your videos ever since you bought the batteries from china. Who CARES if the one piece of cable channel is grey! I couldn't care if it was purple with pink polka dots. as long as it serves its purpose. Your power wall looks great Andy! Well done :) I just got my batrium BMS so will be building mine as soon as I clear space in my workshop area for it to call home.
Yes!! Been waiting for so long to get to this point. It's been awesome to watch you come up with solutions to problems you'd never considered at the start.
Once you get the Weld On for the acrylic, make sure you store it in a fridge...the stuff is crazy volatile and dissipate fast in the heat even if the lid is securely closed.
There are several issues when you don't pre-charge. For one, the inrush current can be higher than the max current configured in the BMS, so the BMS will shut off because of this (over current protection). This is especially the case with larger inverters with lots of input capacitance (low frequency ones in my experience especially). In addition, once you add another inverter, you'll increase this even more to the point of damage to the BMS MOSFETs without pre-charge because now you're pulling a lot more than they are rated for. A REC BMS for example has this pre-charge built in. Those popular EG4 19" rack batteries as well (even though that one seems to be causing some issues with some inverters). Edit: also, it will blow a fast acting Class T fuse for people using those.
And the manufacturers are very, very bad about specifying this. Just asked one about it yesterday and they kind of just shrugged. I think I'm just going to add a second precharge breaker in parallel with a resistor on it and just remember to turn that one on first when powering up.
@@GoatZilla It also depends a lot on the inverter itself. Some of the Victron inverters seem to use very little input capacitance and seem to be fine, while for example mine has 4x6800uF on the input. Mine would definitely trip over-current on the 200A JK BMS at least.
@@upnorthandpersonal Yeah it'd be nice to not have to Big Clive our own products in order to figure this out. It's not just inverters either; it can apply to charge controllers as well.
Ha - already thought about adapting the duct that way during the last video - keep it simple :). I'm planning for a pv with some diy storage at my parents house and for my office here in Germany - not as much sun as in Australia i guess but with energy prices rising steeply getting some of the energy from the sun is the way to go. I really enjoy your videos.
Congratulation - great achievement! :-) But I bet your setup will never be final. Good for you and good for the community. BTW: May I ask you to show all your final settings in BMS and charge controllers. I tried to extract data from your numerous videos but I am not sure if my notes reflect the reality. Same is true for newbies at your channel.
Just a little detail note....as well as a shut down process (great idea👌) you need a label maker and mark/label every thing, switches, boxes voltage ect... You know what I mean you a cleaver chap.
I am precharging because i had a welded main switch after a turning my 3 phase system on. I was not able to turn it of again. The switch is rated for 400 Amps DC.
I guess you found out the hard way to use ethernet for the PI, instead of the flaky wifi. Not going to say I told you so last year.....(but I did, lol) Wifi just isn't reliable for something on all of the time - lightning, microwave or whatever does it. Really, the PI should be a POE device that gets it's power from the ethernet cable too....but it isn't yet. Nice work on cabling. It looks very professional.
In Victron Professional Online Training 9.2. (from 9:40 onwards), Guy mentions that when using sealed isolators the spark/ inrush current is not a problem, if the isolators/breakers are appropriatly rated for DC current.
Do note this is only for Victron inverters, which seem to have a low input capacitance. Other inverters on the market have a much larger inrush current and these can e.g. cause the BMS to turn off (over-current protection) or blow a fast acting class T fuse among others.
Great job Andy! At 8:00 something many people are not aware of is that in the U.S. (Similar in other countries) is that all disconnects and circuit breakers, and panels are to be installed in a readily accessible manor, and kept clear for a distance of 36" inches, or a bit over a meter and clearly labeled. At 7:00 that was a smart hack on the duct corner, and while I didn't do a lot with non-metallic duct lke Panduit, I seem to recall 'L'' and 'T" junction connectors for larger plastic panel ducting that might make life easier if that's something the CCP even cares about making now.
about the precharge - the inrush current is really high. I read from several ppl that their BMS died (fried one or more transistors), despite I think that with fully open transistors (using breaker switch) is probably safer than using on/off switch in BMS (no transition period for FETs). Similary it's recommended to use BMS as an emergency switch only, add communication between BMS and Venus, so those hard limits are never reached and charging/discharging is turned off before BMS has to act. Some corner case with recover value/time could be cycling BMS on and off and that would be really hard on those transistors. I have it set up that recover values are unreachable so if BMS+Venus can't prevent it, any error state must be manually cleared.
Even if the shunt loosened enough to make contact with positive buss bar each battery still has a breaker that would trip I would mount a push button next to your main breaker to pre charge all equipment at once.
I wonder if the 3 ish weeks connection issue with the Pi is to do with the DHCP lease time on your router/AP? It would be interesting to see if the connection is dropped with a manually specified IP/Subnet/Gateway.
I think technically you need some sort of cover/conduit over the cables because your battery system will be regarded as DVC-C due to the charge controllers not having basic separation between the pv and battery terminals. But when making your covers, make sure you dont restrict air flow into the inverter.
Very nicely done Andy!! You are gifted in so many ways but especially in your presentation skills. I’ve learned a great deal from you. I do have a question: what is the correct name for the blank filler plug you used to cover unused breaker positions in the DC Distribution boxes and more importantly where did you purchase them? DIN panels are not a standard in the US. Thank you.
I can see that angle cover popping off. If you didn't glue it on, it could be something you do. It's a small enough piece that permanently glued in place, the space is still accessible with the 2 main covers removed.
2:04 why not just use these wide gray slotted cable tray instead of those white closed cable trays? 16:23 But if you want something white and wide, use PVC tubular drainspout...
I would be really interested in your view on using the Victron Multi RS 48v 6000va instead of the Multiplus or Quattro ??? I’m looking to fill my roof and build a copy of your three parallel 16S EVE LiFePo.
looks great! but what about the rest of the batteries installed on the shelf? also while you are playing with the batteries when you charge them to 3.45 and take the charge away what do they settle down to? 3.3 3.2 after 24 hrs? how do you tell if a battery is degraded other than a load test? let us know
I’d suggest you get yourself an externally powered POE network switch, and a poe hat for your raspberry pi. Then use something like a UniFi dream router or dream machine and use their access points connected to the POE switch. They have cameras too. And then you can power the switch from DC directly.
What cables have you used for connecting to the solar panels (UV stabilised)? Trying to find different options in Australia. PS the jst cable you list on your site for the diy victron USB from core-electronics should have male ends (they have this option but I ordered with your link without thinking and found out the problem).
smiles .. just cut the very inside corner until they all fit neatly .. then just cut piece white plastic and glue/weld the cover edge .. and just manage a piece of plastic to look good and addto make the cover plate .. voila .. still very neat and controlled .. evidence demands a verdict .. hope all the rain hasnt soggied u too much.. beerwah ,,.. we have become webbed appendages and joined the frogs .. lol.. i shall keep watchning now .. cheers ..
Hello Andy. I have a new topic proposal for your expertise. I cannot find any serious comparaison between the 48 v bDIY cells and the high tension batteries. Please try to bring your experience on this !
The unstable WiFi in the raspberry pi is a common thing. There is a power saving mode you can disable that helps, but even then it will still happen. I've found that there's part of network protocol called "ARP" and there's a request the gateway sends out and the devices are supposed to reply, but on the raspberry pi, it gets into a state where it stops responding to these on WiFi for some reason (even with power savings disabled). This is a common cause for the network drop, since the router won't necessarily know the Pi is still there or it's address. On my Pi (not a Venus OS, I made a digital picture frame/slideshow for my wife) I have a script I wrote that periodically pings the gateway to ensure it has a connection, and when it loses it it will reset the WiFi connection. It also forces it to periodically send out ARP responses (using the arping command). Having both these seems to have "fixed" it, but the short version is any time you can wire Ethernet to a permanently installed Pi, that will be best.
I have always had trouble with my WiFi to my building disconnecting and not reconnecting I just ran a wire and said I am done with that I could not find a Bridge that would stay connected.
My raspi does the same thing with wifi, no idea why, but it's in my electrical meter box so I'm not keen on running an ethernet cable down inside the wall to it.
You can put another white channel End for the cable PG chain tube The shunt not need to band for a short to be onley some thing to fall thete so to make a short ???
Andy I went on your website and I've looked everywhere on Amazon eBay all of them where did you find that wide cable gutter I have found small 2 in 3-in cable gutter but nothing that has as wide as you the ones you are showing in the video please help me with a link or point me in the right direction just want to say I'm a big fan love your work on your UA-cam channel and the website thank you very much
Hey Andy, great job mate! I have a similar project myself, which will include 4 x 5kw Growatt inverters, and running 3 phase for fast charging for the Tesla. I've tried looking back through your videos, to see how you are measuring the battery input/output and battery capacity measurement, however, I can't find anything over about a month old. I probably don't know how to use UA-cam, but if you could give me a couple of links to some of your older videos, where you describe that process, I would be most appreciative. I think you used a "smart shunt"? and then what software? Is that BlueTooth or wired? I'll keep looking, but I may not have much luck. Will send you some photos of mine when done.
whats u thoughts on this tecnologia aculta latest uploads mybe put one in ur boot why not put one on every wheel haha think i stick to solar for now bit skeptic

Even if the shunt loosened enough to make contact with positive buss bar each battery still has a breaker that would trip I would mount a push button next to your main breaker to pre charge all equipment at once.
I wonder if the 3 ish weeks connection issue with the Pi is to do with the DHCP lease time on your router/AP? It would be interesting to see if the connection is dropped with a manually specified IP/Subnet/Gateway.
I think technically you need some sort of cover/conduit over the cables because your battery system will be regarded as DVC-C due to the charge controllers not having basic separation between the pv and battery terminals.

On that gray duct cover, you could wrap the cover with white vinyl.
or you can buy a white spray paint and spray the cover. 😄
I can see that angle cover popping off. If you didn't glue it on, it could be something you do. It's a small enough piece that permanently glued in place, the space is still accessible with the 2 main covers removed.
Andy not sure what it is but noticed that some guys use some kind white plastic tubing with a smooth finish
You like the Victron stuff, can all the Victron inverters be run in parallel? On single phase ac?
Not all of them. The Multiplus and Phoenix can, single as well as 3-phase.
@@OffGridGarageAustralia ah cool! Can they run alongside grid power at all? I think some growatt inverters can?
@@DrewNewmanAce Yes, they both can run with grid or off-grid.
@@OffGridGarageAustralia ah cool!!! Thanks for that… love the videos, very informative!!
felicitaciones 🍺
Great job Andy. I have always thought your gutters might be too small though. Maybe some plastic ties might hold your cables in place.
Make the corners with 22.5 degree angles then the covers will work. Like a long elbow in plumbing!!
2:04 why not just use these wide gray slotted cable tray instead of those white closed cable trays?
16:23 But if you want something white and wide, use PVC tubular drainspout...
I think too many spiders will get into this slotted duct over time. I like the look of the closed an better anyway.
watching this video the first time, and its like you stick a pair of "Wiener Würstchen" into the Canal to the cables hahaha
Andy did you find out why one of the terminal connects on the new inverter has that plate and the other one not.
I would be really interested in your view on using the Victron Multi RS 48v 6000va instead of the Multiplus or Quattro ??? I’m looking to fill my roof and build a copy of your three parallel 16S EVE LiFePo.
I’m interested how you are going to solve the problem of power going round in circles.
Inverter -> multi > battery -> repeat
Well, the off grid garage had a good run, I guess now that it is done we will be looking for channels....
Nice job Andy. Well done! You used 70 mm cable. They are a lot bigger than needed? A 50 mm was enough isn’t it for 280amps 2 strings?

Hello Andy. I have a new topic proposal for your expertise. I cannot find any serious comparaison between the 48 v bDIY cells and the high tension batteries. Please try to bring your experience on this !
What brand of panels are you using?
The unstable WiFi in the raspberry pi is a common thing. There is a power saving mode you can disable that helps, but even then it will still happen.

Having both these seems to have "fixed" it, but the short version is any time you can wire Ethernet to a permanently installed Pi, that will be best.
Andy, Are your batteries in the battery rack yet ?
How much will the whole thing cost this far ?
Like I always say, never use a 90 when a 45 will do. 🙂
I have always had trouble with my WiFi to my building disconnecting and not reconnecting I just ran a wire and said I am done with that I could not find a Bridge that would stay connected.
Andy , what is the model of your clamp on meter? I believe I'm seeing UNI-T UT210 D
My raspi does the same thing with wifi, no idea why, but it's in my electrical meter box so I'm not keen on running an ethernet cable down inside the wall to it.
Hi Andy, can you Tell me what circuit breaker Do you use?
You can put another white channel
End for the cable PG chain tube
The shunt not need to band for a short to be
onley some thing to fall thete so to make a short ???
just move the vertical duct over so it's a straight run
Could maybe cut a p-trap pipe in half for that "bended" piece you're looking for??
VenusOS wifi driver probably. Some wifimanagers suck at reconnecting, best to cable it.

Andy I went on your website and I've looked everywhere on Amazon eBay all of them where did you find that wide cable gutter I have found small 2 in 3-in cable gutter but nothing that has as wide as you the ones you are showing in the video please help me with a link or point me in the right direction just want to say I'm a big fan love your work on your UA-cam channel and the website thank you very much
Hey Andy, great job mate! I have a similar project myself, which will include 4 x 5kw Growatt inverters, and running 3 phase for fast charging for the Tesla. I've tried looking back through your videos, to see how you are measuring the battery input/output and battery capacity measurement, however, I can't find anything over about a month old. I probably don't know how to use UA-cam, but if you could give me a couple of links to some of your older videos, where you describe that process, I would be most appreciative. I think you used a "smart shunt"? and then what software? Is that BlueTooth or wired? I'll keep looking, but I may not have much luck. Will send you some photos of mine when done.
