Solar Inverters

The solar inverter is the engine room of every photovoltaic (PV) system. Without it, the DC electricity your solar panels generate cannot be converted into the usable AC electricity that runs your home. At Solar Briton, we stock ahand-picked range of solar inverters for UK homeowners and tradespeople —spanning compact string inverters for straightforward rooftops through to advanced hybrid models that integrate solar generation, battery storage, and Smart Export Guarantee (SEG) management into one intelligent unit.

Selecting the right solar inverter is arguably the single most important decisionin your solar panel installation. A poorly matched unit can clip your system’s output, reduce your SEG export earnings, and leave you facing an expensive replacement far sooner than expected. Getting it right from day one delivers better efficiency, lower energy bills, and a solar setup that earns its keep for fifteen years or more.

Solar inverters broadly divide into three types. String inverters wire all your panels into one circuit — affordable, proven, and perfectly suited to unshaded south-facing roofs. Microinverters clip onto each individual panel, maximizing output on complex or partially shaded rooftops and enabling panel-level performance monitoring via app. Hybrid inverters — far and away the most popular choice among UK buyers in 2026 — manage your solar panels, home battery, and grid connection together, making them the smart pick for anyone planning or already using battery storage.

Every solar inverter we sell currently qualifies for 0% VAT (applicable until March 2027), delivering a meaningful reduction in upfront cost for residential buyers.

Our range covers trusted brands favoured by MCS-certified installers nationwide: Fox ESS, Solis, Huawei, Fronius, SMA, SolarEdge, and Enphase. Output ratings run from 3.6kW for small terraced homes up to 10.5kW for larger properties and light-commercial use.
