Inverter failure can be caused by problems with the inverter itself (like worn out capacitors), problems with some other parts of the solar PV system (like the panels), and even by problems with elements outside the system (like grid voltage disturbances). An inverter failure is when the inverter develops faults that cause improper functioning.
