8kW unit, 10kW of panels - constantly need to reset circuit breakers on PV strings
I have 10kW of solar panels installed, 16 x 330W panels on a NNE roof, and 14 x 330W panels on a WNW roof, in Johannesburg. Now in June 2022 the maximum my system products is 4.5kW at around 11-12pm, with the 16 NNE panels (5.3kW) producing a maximum of 2.4kW on a sunny winter day with batteries at only 30% SOC (there is plenty of demand - our AC demand is around 3kW, and Revov 10kWh li-ion battery set to charge at 90A). I also have to reset the breakers to the solar strings to achieve even this (they only produce around 1.7kW until I put the string circuit breakers down and then up again). As a result I am producing only around 30kWh on a sunny day in winter but need more like 40kWh (am thinking of getting a second battery). Has anyone come across this problem?
Hi Ryan, can you please let us know more info on the DC PV breakers. when do you need to reset? can you please give us logger number and plant name.
