I have two identical strings, both connected in series, one averages 260-280 volts which is within the PV panel specs and the other is only giving me 170-190 volts which is way below where i think it should be, none of the two have any shadows on them.
String with lower voltage will always show higher current with lower voltage while the higher voltage string always shows higher/normal voltage and lower current.
But if i restart the inverter then both strings will show almost the same voltage and current for the rest of the day.
What could be causing this?
