I have just installed 4 X12V 140Wp Mono. panels in series connected to an MPPT controller. I also have an inverter/charger connected to the batteries which are 6 X 6v Trojan connected in series giving 720Ah.at 12V.
The problem I have is as soon as the panels are switched on for the MPPT to charge the batteries they appear to immediately start draining. Indications on the inverter monitor are that the SOC% drops, now I understand that the % is only a rough estimate but why would it reduce so rapidly.
I have checked the cables and voltages all appear correct. The panel monitor snapshot displays panel output as 0.46A, 92.97V and 42.78W. Battery status is normal and charging status is "boost charge" battery voltage is 13.37V, 3.25A there is zero load on the batteries.
I have always used the inverter/charger monitor to give me a reasonable idea of the SOC%.
I am no expert on Solar technology so can anyone help please, any suggestions will be gratefully received.
