I wish there was something like RES where you hover the community name in the list item and it pops up a frame you can choose Block on.

Yah, I’m in N Alberta and a farmer, fixing things at -30 is never fun. Those MC4 connectors are a pain in the ass when they’re cold.

140 is a little light but yah, it’s definitely a solar thing only. It’s possible it bounced over the 150 for a very short time to trip the cutout, and the 140 number you’re seeing is a time-smoothed average in your reporting system. If you’re using something trustworthy like a Smartshunt to get that data, then yah, tripping 10V short isn’t great.

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.

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.
