Embodiment Construction
[0012] The connection structure of each part of the device is as follows: figure 1 As shown, more than one set of photovoltaic array components 1 are connected in series and paralleled to charge the energy storage device 3 through the DC / DC charging device 2 , and then convert it into AC power through the bidirectional inverter 4 to supply power to the grid load 5 .
[0013] The specific power supply methods are as follows:
[0014] At night or during a set time period, the energy storage device 3 is charged through the bidirectional inverter 4 by using the energy of the power grid, making full use of the peak-valley electricity price difference, and playing a role in peak-shaving and valley-filling of the power grid until the energy storage device 3, that is, the battery is fully charged. After charging, charging stops.
[0015] When the photovoltaic array component 1 outputs energy, and the energy emitted by the photovoltaic array component 1 is greater than the energy requ...
