[0002] Photovoltaic inverter (PV inverter or solar inverter) is an inverter that can convert the variable DC voltage generated by photovoltaic (PV) solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverter is one of the important system balance (BOS) in photovoltaic array systems and can be used with general AC-powered equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and islanding protection.
