I've had my system in for just over a month now and other than the initial commissioning, had a total of 2 battery drops to 0%; however, the one I had yesterday (20%-0% drop) seemed to cause me some issues.

The battery charged to 100% throughout the day but then steadfastly refused to discharge at all. I tried restarting the inverted, forcing discharge (which did work but stopped again as soon as ECO mode was reslected), turning the inverter off/on, turning the battery off/on and fiddling about with all sorts of settings etc

I had to do a proper power off in the end. Isolators etc all turned off, wait 30 seconds and then switch back on. Touch wood everything seems ok since then.

Hopefully this isn't the sign of things to come 🙁
