EST12KH/15KH/17KH/20KH series inverter, also known as hybrid or bidirectional solar inverter, is suitable for energy management of photovoltaic, battery, load, power grid and other solar energy systems. Electricity from the photovoltaic panels is used for residential electricity, and excess power can be stored in batteries. When the battery is fully charged, users can send excess power to the utility grid.

When the photovoltaic power is not enough to meet the user's load demand, the battery will
discharge to the load. If there is not enough energy stored in the battery, the grid will supply
power to the load through the system.
