Does anyone know of a 400V output MPPT charge controller? (i.e. one that takes a PV input and can charge a 400 volt battery) The only ones I have heard of are: -The StorEdge, but that requires a regulated input voltage from a string of SolarEdge optimizers -The old Pika charge controller, but...

Was just talking to Robin G on another forum and he was talking about how 400V battery systems are more dangerous for DIYers. And of course they are - 400VDC is worse than 240VAC since it's both higher voltage and DC, which has worse outcomes when you get shocked by it. But I've also noticed...

And then it turns out that although you are the owner, it's your renter who had the 10 year old chained up in the basement. Oops! State killed an innocent man, and let a child trafficker escape! Sorry about that! Tell you what, we'll give his wife and kids a gift certificate to Chick-Fil-A...

Anyone have the pinout for the RS-485 ports on the EG4 5.12kWhr battery? I can't find it in any of their documentation.

Specific question first. I am planning to connect a Sol-Ark 30K to a 400V EV battery for energy storage purposes. You have to do a fair amount of spoofing/translating of the CAN bus to enable the battery and give the inverter what it wants, but there's also the issue of having the EV battery...
