Thank you for showing your system. Your build looks very well constructed and with the future in mind!

[@easypowerwall]

Thanks for the kind words Sam. Stay tuned for next episode....the BMS settings.

I really like your videos and your setup

[@easypowerwall]

Hi Eric, thanks for your kind message. These messages are fuel for my motivation engine :-) Talk to you soon.

[@briansweeney4184]

Love the vid! I'll have to watch it a couple more times. Electricity and magnatism were never my strong points in physics! Thanks!!

[@Cptnbond]

I'm looking forward to learning more about the transfer switch. It's fundamental if you will not back-feed the grid and kill some utility workers, and also ensure that your neutral bonding gets correctly installed for the house consumption when the grid is down. Cheers.

[@easypowerwall]

Hi, thanks for your message. The ATS will appear in a future video. It will be dedicated to the ATS.

[@mellyons4052]

Very very tidy system, clean and simple.. well done 😊

[@ghostwriter6699]

I noticed that the power cables coming from the charger busbars are different lengths as it goes to each battery pack. IE the batteries closest to the busbar (top shelf) has less cable length then the one that's on the bottom shelf. I have found that the batteries with the shortest route or length of travel not only gets used up the fastest but also charged more often.... just my thoughts.

[@easypowerwall]

HI, thanks for your question. I agree there's a little difference in length. Because I have 4 x 15KWh, the current for every battery is pretty low, so losses are marginal. But it's a good topic for a future video. Will show current difference while charging. Stay tuned. Franky

[@VincentDegrave]

Dankuwel voor de info

[@TheJensss]

Great setup! How did you solve the problem with inrush current for the inverters when connecting the batteries? Did you implement a precharge resistor circuit?

[@easypowerwall]

Hey Jens, I actually have a unique system to overcome the inrush current. It's planned for a future video. If my answer receives a lot of "thumbs up"....I will avance the video. Have a nice evening. Franky

[@TheJensss]

@@easypowerwall okay, thanks for the reply :)

[@tim62744]

Nice and tidy job what you think of the sma inverters towards yours

[@easypowerwall]

Hi Tim, I only worked with grid-tie SMA inverters, not with low voltage SMA. Will check their catalogue. have a nice day. Franky

[@ErikRave]

Hello, Thanks for sharing these videos. I’m also on my way to build such system. Please check the multiplus manual, chapter installation. Victron states that the negative battery cable should ALWAYS be connected to the multiplus and it’s not allowed to put switches or breakers on the negative lead. I don’t know why this is… Anyway, good luck and thanks again!😊

[@easypowerwall]

Hi Erik, thanks for your reply. I'm aware I need the ground always be connected with the MP, that's why I installed a fuse in the + line. Normally I will never disconnect all batteries...if I do, the MP will be switched off. Thanks for the remark. Have a nice day. Franky

[@nigelbooth3661]

Hi Franky, thank you for this video. It's exactly the type of video I'm looking for to get specific details of how all the components are connected. I'm curious about something that I have seen on a family member's installation. Like yours, the cable diameter from busbar (Lynx Power In) to fuse is smaller than the cable diameter from fuse to Multiplus II. I don't understand the reasoning for this. My understanding is the current would be limited to that of the smaller diameter cable, so why use two different diameters? I'm hoping you might be able to explain this to me.

[@easypowerwall]

Hi Nigel, For short piece the loss is not high and it's easier to bend the cable between this busbar and the fuse.

[@basiljacob4037]

That’s a great set up. Do you know if the battery banks can pass the Fluvius inspection/certification?

[@easypowerwall]

Hey Jack, they passed my wifes inspection...if it passes there, it passes everywhere :-) Just kidding. No idea if it's passes the Fluvius inspectation. Some builders with similar setups managed to pass inspectation, so I think it's possible.

[@basiljacob4037]

@@easypowerwall Great, I'll try to pass it in around 6 months with 32 cells 280ah, a Deye Hybrid inverter and 36 pannels. I'll let you know. Keep the videos coming!

[@universeisundernoobligatio3283]

If you are thinking of adding more cables to the house think about a conduit, that way you can pull any cable you want at any time.

[@easypowerwall]

Hey, 4 years ago when I started the project I installed a small conduit. It might be possible to add an extra cable. See how it looks like here: sites.google.com/view/diy-powerwall/inverter/all-electric?authuser=0 After 4 years, things got out of hand, never taught the battery virus would bite me that hard. I'll find a way to get the extra cable between point A & B. Bye for now. Franky

[@ericklein5097]

How much resistance does one fuse add to the circuit? 25mm2 seems a bit small for the size of your inverters. Wouldn't it make more sense to do 70mm2 off the bus bar and at least 35mm2 off the batteries to the bus bar? Or do you plan on never running your inverters very hard?

[@easypowerwall]

HI Eric. The cables between the busbars and the inverter are 70mm2. Only the short piece between the busbar and the fuse is 25mm2.

[@PhilippeCJR]

Hoe hou je dit gebalanceerd tusssn de 4 banks? Na verloop van tijd heb je een pack dat voller is dan de andere of niet? Of is er een "bank bms" die alles regelt met de 4 banks? Ik heb een deye 12kw hybrid btw en geen victron

[@easypowerwall]

Hi Philippe. De 4 batterijen of banken hangen allemaal aan dezelfde busbar. De spanning is dus op elk ogenblik op alle batterijen dezelfde. Elke batterij heeft zijn eigen BMS. Werkt prima zo. Frank - EASYPOWERWALL

[@johnbrand5231]

Why did you choose to have your upper and lower battery banks connected with different length of cables to the busbar? Won't this give a higher flow on the battery banks with the shortest cables?

[@easypowerwall]

Hi John, Indeed there's a little difference but the impact is marginal. If I'm using 2KW of energ, that's 500W per bank, +/- 10A, so voltage drop is nearly zero. Difference is only 40cm max, so definitely not a dealbreaker. Have a nice day. Franky

[@tiborchren]

It would be good to add a second row of output terminal connectors to the BMS protection board to allow connection of the active balancer. Is it possible to buy your BMS protection board somewhere?

[@easypowerwall]

Hey Tibor, The board is connected to a JK BMS. The BMS has an active balancer onboard. (my version 1A) But I agree, it might be interesting to have a bigger balancer when cells get out of wack after many cycles. I was planning to launch a sale of the board when the in depth video about the BMS protection board was published. Will contact you via FB group: facebook.com/groups/1076897519357184 BTW have to add some minor tweaks. As always the gerber files will be available too If you want to order the parts and PCB yourself. Talk to you soon. Franky Easypowerwall.

[@ericklein5097]

@@easypowerwall unless your cells are Grade (G)arbage the 1A balancer should be plenty

Hello do u have any video how to setup the bms ?

[@marcvandaele1878]

Hi Franky ik ben nu al uw video’s van voor naar achteren aan het bekijken en zelfs dubbel😅 Maar als ik het goed begrijp, tussen uw panelen en Mppt zijn er fuses breakers en nogmaals breakers met spd gemonteerd.. is dit voor een bepaalde reden? Is het niet voldoende om fuses of breaker en spd tussenin Bedankt Marc vanuit de Filipijnen en bijna startens klaar om ermee te starten

[@easypowerwall]

Hey Marc, Correct, die dubbele zekering & SPD tussen combinerbox en MPPT is misschien overkill. Je kan ze zeker weglaten zonder aan veiligheid in te boeten. Succes met het bouwen, kijk uit naar je project. Groeten uit Belgie.

[@d.r7585]

You live in Belgium, how did you get this approved for your insurance? Cause in BE you need your home battery packs approved if I m not mistaken.

[@easypowerwall]

My setup is not approved. It's full off-grid and the only inspection it passed is the approval of my better half :-) My insurance agent saw my installation, really liked it and never asked a question.

[@I_m_watching_you]

knappe installatie Franky

[@Mister-D]

Beste ik vermoed dat u Nederlands spreekt ik heb de video door het blad van de zendamateurs. de eerste automaat is een wisselspanning automaat type c dus voor hogere pieken tot 10 maal hoger en springt trager af, maar is enkel voor wissel spanning niet voor dc volgens mij. wij gebruikten deze voor hoogspanning trafo's die diende voor neon reclames en zo voorts. volgens mij zijn deze helemaal niet geschikt voor DC. misschien toch eens goed checken. groeten anders niet beveiligd.

[@easypowerwall]

Hallo mister D. De automaten zijn zeker voor DC. Je kan trouwens geen AC automaat gebruiken in DC kring, die zou vrijwel meteen afslaan. Maar ik ga me zeker eens verdiepen in de karakteristiek van de zekeringen, bedankt voor de feedback. Mvg Frank, ON7RU
