I have a 3000w Growatt in my RV, with 8s2p LiFePO4 batteries and overkill BMSs. I currently have the charge settings set to absorb 28.2 and float 27.2. The batteries are kept at full charge by the solar that is always on. I am reading that when the batteries are not in use for long periods of time you should store them at about 50% SOC. Should I adjust the Growatt so that the batteries are sitting at 50%? If so whats the best way to do it?
