A solar inverter is an important part of a home solar system. It converts the direct current (DC) stored in batteries into alternating current (AC) that can be used by household appliances. Most homes use AC power, although solar panels and small wind turbines often produce DC power. This is why inverters are an integral part of off-grid and grid-connected solar systems.

Uses and Benefits of Solar Inverters
In the absence of a backup grid, battery-based inverters can meet less demanding requirements.
However, if there is an accessible grid, a system with a hybrid inverter can take advantage of it, and has the added benefit of storing power with batteries when the sun is not shining.
If the roof is heavily shaded, a microinverter system is a good choice because it has an inverter on each photovoltaic (PV) module and each module is managed separately to provide excellent efficiency and high throughput.
