Abstract
A photovoltaic energy storage system and a control method for the photovoltaic energy storage system are provided. The photovoltaic energy storage system includes an energy storage unit, a photovoltaic array assembly, an inverter and a rapid shutdown switch. The inverter is electrically coupled to the energy storage unit and the photovoltaic array assembly. The rapid shutdown switch is electrically coupled to the inverter, a power grid and a load. A detecting and controlling circuit of the inverter detects at least two of a first voltage, a second voltage and a third voltage, and determines whether the rapid shutdown switch is turned off according to the detected voltages and a reference value. When it is determined that the rapid shutdown switch is turned off, a connection between the inverter and the energy storage unit and a connection between the inverter and the photovoltaic array assembly are cut off.
