Hello everyone,

I've had my solar (18x LG 370) + battery (8.2kWh) for about 18 months and wasn't aware this forum was a thing until today...... so be gentle as this is my first post.

Not had any issues with the system that I've noticed and I have the dashboard running in the background when I'm working during the day as I like to keep an eye on what's going on, but last night my battery decided to fully discharge:

I don't have any Timed Discharge or Export set and the Inverter is in Dynamic mode.

Is this some sort of expected maintenance/calibration cycle it's doing as I've not seen it happen before?

Thanks for the reply, I hadn't considered it to be a sudden drop to 0 as the top half of the graph made it look like it happened over 30 mins but looking at the battery percentage it is pretty sudden.

I'll give that thread a read as it sounds like it's the same thing.

Cheers.

Yes, this looks like an SOC drop, followed by an emergency charge back up to 4%, to keep the battery safe.
