What happens if a DC inverter is oversized?The inverter limits or clips the power output when the actual produced DC power is higher than the inverter’s allowed maximum output. This results in a loss of energy. Oversizing the inverter can cause the inverter to operate at high power for longer periods, thus affecting its lifetime.
Do PV inverters oversize?PV inverters are designed so that the generated module output power does not exceed the rated maximum inverter AC power. Oversizing implies having more DC power than AC power. This increases power output in low light conditions. You can install a smaller inverter for a given DC array size, or you can install more PV modules for a given inverter.
