Hi
New to this, searched and could find an answer.
Trying to get a ballpark (sanity reassurance) on how long it takes to charge my 48v battery bank.
its been sitting around 53-54v for a couple of days now. Starts off at 53v in the morning, and ends at 54v in the evening
Bank is made of 16x280ah EVE cells with a DALY BMS (48v 250a, non-smart)
Solar is via 6x350w (2 banks fo 3 panels, one bank for each MPPT), 40voc, 9amp, panels in series which daily im getting an average of low of 300w peak of 700w as the day progresses
have 2x MPP PIP LV 3048 charger/inverters, MPPT 144voc, 80a
each unit is outputting about roughly 400w, 90v, 9amps for 6 hours of the day
Battery settings are:
Bulk, 58v
Float, 54.4v
Low, 48v
Given all this, what is the realistic time it should take to charge this sized bank, are we talking hours/days/weeks ?
not really sure what to expect so really just checking my sanity and what i should realistically expect.
Feel like i got to from 52v (about 3.3v per cell) to 53.5v (about 3.35v per cell) pretty quickly. but since then its dragging.
Thanks for any insight you can give me
