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. Verify the PV array wiring polarity relative to battery negative. Check for a short circuit in the PV input circuit and repair it. Controller input and output voltages read about the same.
How do I avoid a PV system failure?
The best way to avoid system failures is to install a high-quality, properly designed PV system. A regular maintenance program helps eliminate system failures. The most common system failures are usually the easiest to fix. Check the system first for basic problems to save a lot of time.
Why are batteries undercharged?
Batteries are undercharged. The system array is not producing enough charging current because of an extended length of time with cloud cover. Reduce the building's electrical load or adjust the PV system size for more days of autonomy. The building's actual electrical load is greater than the calculated load.
