A solar inverter with grid connection and battery is a device that converts the electrical energy produced by a photovoltaic system into alternating current (AC) and uses it to power the household appliances and electrical devices of a home or building. It can also be used to charge a battery that is used to store electrical energy for later use when solar energy is not available.
The solar inverter with grid connection is connected to the local power grid and sends any excess electrical energy produced by the photovoltaic system to the grid. This means that the home or building can use the solar energy produced during the day and also receive electrical energy from the grid when needed. The battery is used to store electrical energy for use when solar energy is not available, for example, at night.
