Hello all,
please I need your help, I am new in the solar energy world , i installed last weel 12 panels 405W each, the configuration is 4 groups of 3 series panels. so each each group is <140v VOC under the PH18 5045 PLUS MPPT limit which os 145V. my problem is that I mostly need the system during the day more than over the night in Lebanon when there is an electricity crisis. the idea that Untill I import batteries I am uusing 4 old cosumed battery (distinct model, size,..) so I am using them just to make the inverter launch because it requires batteries, my needed power is 2000W. my face problem is that even if the sky is totally clear, the sun is pure if I load the inverter around 1800W it starts consuming from the batteries continuously (I waited 3 min and that values almost the same) around 1100 watts. is it logic for a solar system 5Kw inverter and panels during sunny days to take from batteries to feed 1.8 Kw charge instead of the solar panels charges the batteries and feeds the home appliances?
