Hallo Solar Enegy Entusiasts, I am in this Forum to get more knowledge on how Solar Panels work.
In my attempt to realise an off rid system, I have connected 2 Solar Panel ( Open Circuit 91 V. from first Solar) to a 30 amp Charge Controller .
When I had only 1 Panel, I realised 12 Volts of charging on a 42 V ( trial) Car Battery. Now I have added a Second Panel ( to cover the evening Sunlight), and upgraded my Battery to A 12 V- 100 ah SOLAR BATTERY.
Now, I am only able to realise 11. 3 V at most. What am I not doing correctly.
Additionally, when I measure my current output from my Panels, I read 45 to 90 Volts. But when I connect it to my charge controller, it produces only 13 V. Max. Why is this so. How can I tap current direct from the Charge Controller during Sunlight- without discharging my Battery?
