New to all of this. For my offgrid cabin, installed a Growatt 3000 connected to a Eg4 24volt battery, powered by 2 - 300 watt solar panels. System is in an unheated outbuilding, not severe weather here in Central Washington state, but temps below freezing. Major concern right now is keeping the battery warm enough to not cut off. Should I be thinking about exchanging for a heated battery, and if so, what brand? Or, perhaps a heating pad? Not sure if my system would keep up with energy needed to power heat for the battery. System does not get a lot of use, as I don't get there too often. Or, better to put inverter in standby and switch battery breaker off when not there? And, if I understand correctly, I need at least a 6000w generator to recharge the battery through the inverter - maybe best using a 24v battery charger run by a generator. Thoughts? Any recommendations for a charger? Thanks for your time. Appreciate any advice as I am on a steep learning curve.
