The inverter is arguably a more consequential choice than the panel, because it is the component most likely to need replacing during the system’s life.
As with panels, we do not recommend brands. Here is what UK installers commonly fit and what to check.

What you are likely to be quoted
Manufacturers commonly fitted in the UK domestic market include Huawei, Solis, SolarEdge, GivEnergy and Fox ESS.
Some of these matter for reasons beyond the inverter itself:
- SolarEdge is built around panel-level optimisers, so choosing it is partly a choice about how shading is handled
- GivEnergy and Fox ESS also make batteries, so choosing one can mean choosing a battery ecosystem at the same time
No primary source publishes UK inverter market share. This reflects installer-facing and comparison sources and is a guide to what appears on quotes, not a ranking.
What to check, whichever brand
Is it a hybrid inverter? If there is any chance you will add a battery, a hybrid inverter now avoids replacing it later. This is the single most consequential question on this page. See hybrid systems.
Warranty length, and whether it can be extended Inverter warranties are typically shorter than panel warranties, which tells you about expected life.
UK support How a claim actually works, and how quickly a replacement arrives. The system generates nothing while the inverter is out, so response time has a real cost.
Number of MPPT inputs, if your panels are split across roof faces. One per face is the clean arrangement. See multiple roofs.
Rated AC output, and how it interacts with your grid connection. See grid connection and inverter capacity.
Monitoring Is there an app, is there a subscription, does it need a permanent internet connection, and can you see panel-level data? Monitoring you will actually look at is how you notice a fault.
Battery compatibility, if you plan to add storage later. Some inverters work only with the same manufacturer’s batteries, which narrows your options down the line. Ask explicitly.
Noise and siting Inverters hum and generate heat. Ask where it is going and why. A garage or utility room is kinder to the electronics than a hot loft, and much easier to reach.
What matters less
Small differences in stated efficiency. Modern inverters are all highly efficient and the difference between two reputable units over a year is marginal compared with shading, orientation and how much of your generation you use.
A note on ecosystems
Increasingly, choosing an inverter means choosing a manufacturer’s wider system: their battery, their app, their compatibility rules.
That is not necessarily bad. An integrated system often works more smoothly than assembled parts. But it does narrow your choices later, and it concentrates your exposure if the manufacturer has problems. Worth being conscious of rather than sleepwalking into.
