Solar inverters
The inverter is the brain of a solar system. It turns the DC power from your panels into AC power that your home can use, and on hybrid models it also manages a battery.
Picking the right type matters more than any single spec, which is why we group the range by type and by brand. We carry string inverters for simple roofs and hybrid inverters for battery-ready installs. We also list microinverters, which suit shaded roofs where panel-level monitoring helps.

Brands we stock & compare
Brand matters because it sets firmware, monitoring and battery compatibility. Victron is the off-grid and leisure benchmark. Sunsynk, Solis, Growatt, Solax and FoxESS cover most UK grid-tie and hybrid installs, while Renogy is popular for 12V and 24V campervan and off-grid setups.
How to choose solar inverters
Choose the inverter type first. A string inverter suits a roof with even sun, because all the panels feed one unit. However, shade on a single panel can pull down the whole string, so microinverters help on busy roofs.
Next, decide whether you want a battery now or later. A hybrid inverter costs more than a string unit. Even so, it saves you buying a second inverter when you add storage, which suits many new installs.
Finally, check the size of your supply and the grid rules. Larger homes and commercial sites may need a three-phase unit. You also need to tell your network operator about a new inverter under G98 or G99, depending on its size.
Our solar inverter comparison sets the main brands side by side. Moreover, the home battery storage cost guide explains how a hybrid inverter and a battery fit together, and the solar panel kits buying guide shows how kits include an inverter. For a full system, you can also browse battery storage and solar panels and kits.

Solar Inverters — common questions
What's the difference between a string and a hybrid inverter?
A string inverter only converts solar DC to AC. A hybrid inverter does that and also charges and discharges a battery. Therefore, it is the better choice if storage is on your plan now or later.
Do I have to match the inverter brand to my battery?
For hybrid systems, battery compatibility comes from an approved list for each inverter. For example, FoxESS inverters pair cleanly with FoxESS batteries. Check the compatibility list before you buy, and use our comparison guide for the main brands.
