The household energy storage system is a new type of hybrid system for energy acquisition, storage and use, based on the traditional grid-connected photovoltaic power generation system with the addition of lithium batteries to store electricity, which is a combination of batteries, hybrid inverters and photovoltaic panels.

    Household energy storage systems operation mode：

      1, Morning: the light intensity in the morning is weak, resulting in low energy generation, while this period is high energy demand; at sunrise, the solar panel starts to generate energy, but it is not enough to meet the morning energy demand, so the energy stored in the energy storage battery is usually used by the electricity-using load at this time.

    2, noon: the most vigorous light intensity, the highest energy production of solar panels, while this period is low energy demand. The energy produced by solar panels reaches its peak during the day. However, as family members usually go out to work or attend other events at this time, the electricity demand is low at noon, so most of the energy produced by the solar PV panels at this time is stored in the energy storage systems batteries, and excess electricity is sold to the electricity company on a grid-connected basis.

    3, Evening: The light intensity is weakest at night, with low energy production and high energy demand. The highest daily energy consumption is at night when solar panels produce little or no energy. The lithium energy storage system uses the energy stored in the battery energy storage system (bess) during the day to meet the energy demand.
