48V Inverter/charger vs. MPPT SCC float settings for AGM string
My XW6048 charger is set to a float voltage of 55.4v for my AGM battery bank (4 cells in series in 2 parallel strings), but the float voltage of my SCC is set to 54.0V by default. Wouldn't that use grid power to keep the batteries topped off instead of PV? I would think the SCC float voltage should be set a little higher than the inverter's charger, but by how much, and what should the voltage ideally be set to? Thanks in advance!
XW6048, 3.4KW PV, Grid-Tied, always tweaking.
