My RV has 2 x 100Ah gel cells. AC charger, alternator charging, and solar charging. None of these are LiPO4 compatible. I also have a 2kW inverter, which I don’t plan on changing,
Plan to change to LiFePO4 batteries, Victron Phoenix Smart IP43 50A (1+1), Victron DC/DC charger, Victron solar charger.
Regarding the Phoenix Smart IP43 50A (1+1) storage mode when using LiFePO4 batteries:
- How does it determine 24hrs of no load? It must be based on a (minimal) voltage drop criteria? What is that voltage drop that makes it think there is a load?
- Is the store charge voltage user adjustable? I would like to store the battery at 50-60% (so 3.26 - 3.27 V / cell or 13.0 - 13.1 V for the battery).
- How does it get the battery down to this store voltage? Or do I need to drain the battery to say 50% prior to plugging in AC, and letting store charge mode activate? How do I prevent it charging to 100%, prior to store charge activating.
The camper is stored in a garage (which does have a couple of skylights). I guess I would need to turn off the solar charger when parked up in the garage and plugged into AC (with the AC charger doing the storage).
Thank you!
