Hi Folks
I'm a solar newbie and recently setup my 1st system. I have been monitoring my battery's state of charge (using resting voltage at first, and later, a battery monitor). I manually shut off the solar panels when my battery gets close to full because I am not confident that the charge controller won't over-charge the battery.
How can I make sure the charge controller will prevent over-charging?
Here is some info about my system:
Design Drawing
Link to Drawing
Two 200W Panels Wired in Series
Link to Manual
Maximum power (Pmax): 200W
Voltage at Pmax (Vmp): 17.0V
Current at Pmax (Imp): 11.76A
Open-circuit voltage (Voc): 20.23V
Short-circuit current (Isc): 12.45A
MakeSkyBlue 60A Charge Controller v118
Link to Manual
Charging Voltage accuracy: ± 0.2V
Overcharge protection voltage - 12V Bat: 15V
Limited current protection: 61A
Max PV Module for 12V Bat: 720W
PV Module Open Circuit Voltage for 12V Bat: DC20V ~ DC80V
Voc of PV should be 1.5 to 2 times greater than battery voltage for best efficiency
Controller Charging Voltage for 12V battery: 12V - 17V
My settings (see manual for explanation):
