I have three 150 watt 18v panels in parallel in a 12v system, I have 8 metre AWG 7 wires (10mm cross section), I have a 50 amp PWM charge controller/inverter (hybrid). Today was very sunny and hot, the 200AH gel battery is being charged but is showing 0 amps and 12.2 volts for the battery and the PV voltage was 19v for a short while but has been stuck at 12v for most of the day. The sun is fully reaching the panels and there is no shade.
The highest I have seen the charging reach is 23 amps and 13.8 volts. I have never seen it go higher even though I have selected the "AGM" setting which allows the voltage to reach 14.1v (the "flooded" seeings which allows it to reach 14.6v also did not help).
Today at one point the charge was at 8 amps but when I removed washing machine off the electricity it jumped to 15 amps immediately (????).
What's confusing is that the battery is more than half discharged and yet the amps are still 0 when the sun is out and shining.
Could anybody help me figure out what is going on?
