Abstract
An energy storage apparatus, including a plurality of battery modules, a switch unit, a start unit; and an electrical energy output port. The energy storage apparatus is configured for use in a photovoltaic power generation system having a plurality of photovoltaic modules, a direct current-to-direct current (DC/DC) converter, and a direct current-to-alternating current (DC/AC) converter. The plurality of battery modules is separately connected to the start unit and the switch unit, and the plurality of battery modules are configured to, when the start unit receives a start signal, control the switch unit to be turned on. The energy storage apparatus is configured to, in response to the switch unit being turned on, output electrical energy of the plurality of battery modules through the electrical energy output port, and, in response to the switch unit being turned off, disconnect the plurality of battery modules from the electrical energy output port.
