With the increasing popularity of home solar battery storage boards, home solar battery storage, which can obtain and store electricity from these devices, has attracted more and more attention. In the future, such a home solar battery storage system will not only benefit homeowners, because they have greater autonomy in how and when to obtain the required electricity, but also benefit the power sector, because people will shift their electricity demand During off-peak hours, thereby reducing the load on the system.

The home solar battery storage system is generally composed of a photovoltaic array composed of solar cell components, a solar charge and discharge controller, a battery pack, an off-grid inverter, a DC load, and an AC load. If the output power is AC 220V or 110V, an inverter is also required. The photovoltaic array converts solar energy into electrical energy when there is light, and supplies power to the load through the solar charge and discharge controller, and at the same time charges the home solar battery storage.

When there is no light, the home solar battery storage group supplies power to the DC load through the solar charge and discharge controller. At the same time, the home solar battery storage also directly supplies power to the independent inverter, which is inverted into AC power through the independent inverter, and supplies the AC load powered by.
