I have 2 batteries 12V 80Ah deep cycle lead in series for a 24V system.
I connected an invertor directly to the battery pack.
I have ~600W (~44V) of solar panels connected to the PWM charge controller.
As soon as I use like in this example 1000W on the system, the charge controller just stop transmitting Amps to the battery. (And voltage drops.)
Resulting in a voltage drop like that (captors on battery pack 24v) :
- Black line is battery full + voltage added from solar panels. ~28.8V
- blue line is battery full. (At night should be around there) ~26.8V
- red line is maybe ~23.5V
It seems to restart the charge after few hours.
Is there something wrong with my Charge controller ? With my setup ? :/
