Why is my PV array not working?
If the input side voltage and current from the PV system array are operating at a reduced level, the problem is most likely with an array string or with a specific module. This means you'll need to go to the array location next. In a grid-tied PV system, the AC output from the inverter fluctuates with the amount of sun.
Why does my PV array have zero volts?
The PV wires from the array may be connected in reverse polarity, or there could be a short circuit in the PV input, resulting in zero volts of input voltage.
