@ggw I left ours in AGM volts mode for maybe 2 months, the adaption was automatic but slow. I did try and hurry it along by manually tweaking the A...
We have 304Ah batts too, but after letting the sunsynk auto detect to the size, it thinks they are vastly different to this. Our system now works ver...
When we first installed our Sunsynk I initially tried to use Li-bms as the battery state - this was dreadful, resulting in all sorts of weird behaviou...
@ggw I had a lot of trouble with the sunsynk originally(ok, I still do…). New LiFePo4 battery, with the Seplos bms that talked with it, and yet I fou...

@ggw I think the cable to the unit needs to be double insulated if you can touch it. Ideally the twisted pair from the CT should be away from any ma...
Personally I think it's only worth insuring stuff when your life would be really difficult without it. Home against fire, car, medical if you're on h...
I used 50mm2 cable, sunsynk 3.6kW to 100A givenergy breaker to 280L fogstar. 50 is the largest that fits all the above.
