Solar Inverters

A solar inverter is used to convert the variable direct current (DC) electricity produced by solar PV panels into alternating current (AC) which can then be put in to the national grid network or used by off grid power systems. Because solar PV panels cannot produce AC power, a solar inverter is necessary for a solar installation so that regular appliances can be used with the power produced.

Types Of Solar Inverter
There are 3 main types of solar inverters which can be used depending on the application.

Grid Connected Inverters: These inverters match phase with the ulility supplied sine wave power. They are designed to shut down automatically when there is a power loss for safety reasons. They don’t provide backup during power outages.

Stand-alone Inverters: This type of inverter is used in stand-alone applications and draws DC power from batteries which are charged by PV panels. Many of these inverters also have a built in charger with which they charge the batteries from an AC power source where available. They almost always have no connection to the national grid.

Battery Backup Inverters: These inverters are designed to draw power from a battery, manage the battery charge through a built-in charger and export excess power into the utility grid. These inverters are capable of supplying AC energy during power outages.
