Hello guys,
I have following system(see attahments) installed at my home. It comprises of 6 panels; each of 200 watts,a dual inverter(utilizing both solar and Utility power to charge battery)+charge controller, and two batteries 150Ah each. I live in Pakistan where we get of 9-10 hours average sunshine and very little cloudy days.I have these panels connected in parallel and the panel current for 5-6 hours is 38-42 Amps and voltage 28.5-29v and during 2h in morning and evening 1 hour Amps drop down to 30-35 depending upon sun.These measurements have been taken directly from solar panels without connecting to Charge controller/inverter or Battery.
Now the problem is when i connect panels to charge controller and batteries the batteries seem to take only 6-8Amps even when they are 25% and no matter how much load i apply the current from charge controller remains the same.In contrast when i switch the inverter to utility charging mode and disabling solar charging mode the batteries start taking 22-25Amps of charging current and they charge pretty quickly.But When i switch inverter to Solar charging mode the Charging current Declines and batteries take only 6-8Amps and when i increase load to 200-250 watt the batteries start excess power instead of Charge controller increasing Amps from panels.
I have tried 2 different types of charge controllers but the problem persists.Please Reply if anybody knows Why charge controller is wasting 20-30 amperes and giving 6-8amps only to Batteries Thanks in Advance.
P.S: i think the person in this thread http://www.solarpaneltalk.com/showth...rge-controller is suffering from same problem but i have checked all my connections but still no luck.
