How Does a 3-Phase Solar Battery Operate in Home Backup Systems?

A 3-phase solar battery operates in home backup systems by storing solar energy for later use. The main components include solar panels, inverter, battery storage, and electrical distribution system. Solar panels capture sunlight and convert it into direct current (DC) electricity. The inverter then converts this DC electricity into alternating current (AC) electricity suitable for home use.

In a 3-phase system, three separate currents flow out of the inverter. This setup provides balanced power, improving efficiency and enabling larger energy loads. Once the solar energy is generated, the excess electricity can charge the battery. The battery stores energy for use during periods of low sunlight or power outages.

When the grid goes down, the backup system draws energy from the battery. The inverter again converts this stored DC electricity back to AC for home appliances. A control system manages the flow of energy, ensuring efficient use while prioritizing battery charging and discharging. Overall, a 3-phase solar battery enhances energy reliability and reduces dependence on the grid.
