An inverter becomes an essential part of any PV system that is intended to power anything beyond small lighting and appliance loads. A standard inverter enables the use of alternating current appliances. An inverter does have efficiency losses and stand-by consumption losses, but it makes a PV system far more versatile. It may still be desirable to incorporate DC lighting and appliances as they are more efficient and do not require the inverter to operate to function. The inverter may be operated only intermittently in a system of with this design. DC has disadvantages for lighting and loads when it has to run longer distances due to voltage drop.
