Last year I installed a new solar
panel, controller, and batteries
for my house loads.
My usage is such that I am shedding power everyday by 2pm or so, meaning I reach 100% SOC every day. In the morning when I get up the lowest number I have seen on my Balmor Smartguage is 77%.
My bank is 2-6 volt GC2 Duracell Ultras with a 215 Ah rating, made by West Penn. The charging
parameters on the controller are set correctly for these batteries
, with one exception.
I read recently in the manual for a similar battery
(the Trojan T105), that if one does not discharge them below 70% the recommendation is to NOT equalize.
The Rover controller has a setting that makes it do an equalization
charge of 14.8 volts for 2 hours every 28 days. I have been monitoring it and it is doing just that.
I would prefer it did not, so I wrote to Renogy tech support and they say I cannot change the setting.
Anyone here have any input on this issue?
