What is the best practice for LiFePO4 batteries when they are sitting idle for long periods between use? Would it be best to let the PV and MPPT in to keep them charged or it is better to shut they system down and turn everything back on when the cabin is in use? The cabin goes unused for months at a time. A few times a year it is used for a full week or maybe a weekend here or there but most of the time it is empty.
