What is Inverter?
A device that converts the DC electricity produced by solar panels into AC electricity used in your home.
Quick Answer
Most Irish residential installations use either string inverters or hybrid inverters. Hybrid inverters are increasingly popular as they allow battery storage to be added later. Leading brands in Ireland include SolarEdge, Huawei, GivEnergy, and Enphase. Installers must comply with ESB Networks connection requirements for inverter settings.

Inverter Explained
A solar inverter converts direct current (DC) electricity from solar panels into alternating current (AC) electricity at 230V — the standard used by household appliances and the grid. Inverters also manage power flow, monitor system performance, and ensure safety through anti-islanding protection. There are three main types: string inverters (one unit for all panels), microinverters (one per panel), and hybrid inverters (which also manage battery storage).

Frequently Asked Questions
Where is the inverter installed?
Inverters are typically installed indoors near your consumer unit (fuse board), often in a utility room, garage, or hot press. They need a well-ventilated location.
How long does an inverter last?
String inverters last 10–15 years, microinverters 20–25 years. Most come with 10–12 year warranties, with optional extensions available.
