A grid-tied solar inverter is a device that converts the electrical energy produced by a photovoltaic system into alternating current (AC) and uses it to power the appliances and electrical devices in a home or building. However, unlike a grid-tied solar inverter with batteries, this type of inverter does not have the ability to store electrical energy in a battery for later use.
The grid-tied solar inverter without batteries is connected to the electrical grid of the location 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. However, when there is no sunlight available, there is no way to use the energy stored in a battery and one must rely entirely on the electrical grid to obtain power.
