Composition of household energy storage systems

 Introduction to household energy storage system 

The structure of household energy storage system includes: photovoltaic modules, energy storage batteries, energy storage inverters, grid-connected and metering equipment, public power grid, household loads and important loads. PV energy first meets the power consumption of important loads, then charges the battery, and finally flows to household loads, and the excess flows to the power grid.

 Working principle 

 In the morning , when there is sufficient sunlight, PV energy will first supply the load, and the household load will consume the photovoltaic power generation to the maximum extent, and the remaining power will be stored by the battery; when there is insufficient sunlight, the battery will supplement the power to the load.

 In the afternoon , after meeting the consumption of household loads and the battery is full, the remaining power will be fed to the power grid.

 In the absence of sunlight  , the battery is converted into AC power through the inverter for use by the load.

When the battery cannot meet the power demand of the load, the power grid will supplement the power for the load.
