What kind of charger are you using that needs to voltage match the batteries? I’m running 500V strings on a Luxpower 18K and it’s not an issue with the chargers in that.
Schneider MPPT 150. We sell a lot of Schneider at work and I got a good price on it. However it’s totally a piece of crap. It’s the only “150v” device I’ve ever seen where 150v is the do not exceed voltage rather than the operating voltage, and it will trip offline at 140v which causes a huge issue here in Canada where OCV can rise greatly below -20C.
Wouldn’t recommend Schneider in general as they require their own proprietary CANBus mod to get telemetry out of any of their equipment.
That’s been my impression of Schneider, great on AC but their solar stuff is a placeholder for “nobody every got fired for buying Schneider”. I thought they ran Modbus on their comms, pretty sure I’ve seen the modbus maps for them around the Homeassistant forums. Maybe it’s just some equipment, but the Conext is modbus afaik.
I wouldn’t say the “150V” should be operating voltage by default, most SCCs I’ve used put that as the “do not exceed” number, just like the current. I’ve smoked relatively expensive charge controllers by being slightly over either of those numbers. Though Victron seem to be able to take it for a while without cratering.
