Hi,
my off-grid system consists of 14 solar panels 410 W, Voltronic 48v 5300w Inverter and 12x Leader LDR INV TT 220AH/12v set in 3 parallel banks of 4 batteries each.
I ran the 230V output from the inverter directly into my electrical panel.
This system is online for less than 1 week.
Bulk Charging voltage is set to 56.4v and Floating Charging voltage to 54v.
I don't have an issue during the day where the load can go up to 2.5kw where power is taken directly from the solar panels without the battery intervention.
But when the sun is down, battery drops fast to 50v (in few minutes) and stabilizes there and start dropping gradually to reach around 47.5 around sun set.
Load at night is around 800w.
I'm worried about this instant drop, is it normal? I also noticed that after battery drops to 50v, if I charge it using grid power it goes up rapidly back to 54v, is this also normal?
Any thoughts on this?
