Powerwall 2: backup function in a 3 phases installation - Alexandre Lechenne - 18.05.2020
Submitted by alechenne on May 18, 2020
Hello everybody,
I recently installed 3 Powerwall2 batteries with the Powerwall Gateway. The electrical installation is using 3 phases. I installed one Powerwall on each phase. The Gateway and the Powerwall have the lastes firmwares. When I run the setup in installer mode/level, I can only check the backup functionnality for 1 phase, and not for all the 3 phases (see screenshot). Has anybody an idea how to bypass this limitation and/or why there is such limitation?
Thanks in advance for your support.
Kind regards

According to the DACH support from Tesla, it seems that it's impossible to activate the backup feature of the Powerwall2 for each phase, even if you have 1 Powerball connected to each phase. I asked to know the deep motivition of this limitation (electric or electronic, electrical regulations or software functionnality limitstion) and will post here when I'll get the detailled reply.
Kind regards
