I have a small PV system for my shed. Just setting up and testing at this point.
- 90W panel
- MPPT T20 charge controller - 20 AMP
- 120ah 12 volt battery
Only one led light connected to load.
I am not sure if the battery is just not discharged enough for charging or my panel controller is not allowing the battery to charge? The icon for sun does not show anything at all. The panel is producing some load according to my metre.
