Hola. Just a quick question. I just checked the batteries (20 month old exide duel)
Most had specific gravity reading around 1.250. One cell read 1.175.
showing 90% charged, voltage 13.2V, 10A going in via solar
A couple of batteries were low on fluid (just over the plates) so I added some and will check those tomorrow.
For now, the battery
with the low sg cell...does it need immediate replacement or removal
from the bank?
is 100% by solar
. We have the solar charger
set to 14.8V for 12 hrs absorption. Most days we range between 75%-100% charged. Battery monitor
seems close enough, we see the acceptance rate drop in the afternoons to 10-15A when around and over 90%.
The bank is 6 X 140Ah. 1150W solar and victron 150/85 mppt
