The honest answer
Is Fox ESS any good, the honest answer
Yes. Fox ESS is our value-focused pick, not a corner-cut one. The EP12 battery carries a genuine 10-year, throughput-backed warranty (43.19MWh across a 10kWh unit), and the inverter includes AI-led grid trading. On provenance: Fox ESS is a Chinese-founded, internationally-listed manufacturer with a UK presence and established UK distribution, the same footing as most of the battery brands in this market, including components inside plenty of "British" systems.
Cost & payback
What a Fox ESS system costs, and when it pays for itself
Our general 5kW solar + 10kWh battery system guide starts from £8,825 including scaffold. As with every brand we fit, we aim to get every customer's payback under 7 years, with most landing 6–8 years. A Fox-ESS-specific figure depends on your usage and is confirmed at a free survey.
The Fox range we fit: the EP12 battery and the hybrid inverter
Modular batteries paired to a Fox hybrid inverter for warranty and compatibility.
Fox EP12 battery
10-year warranty, 43.19MWh throughput per 10kWh unit, the workhorse of the range.
Modular, stack as you grow
Add capacity later rather than overspending on day one.
Hybrid inverter, brand-matched
We always match the inverter brand to the battery for warranty and compatibility, never a mismatched micro-inverter setup.
AI grid trading built in
The inverter can trade against a time-of-use tariff automatically, without you having to manage it manually.
Fox vs EcoFlow vs Tesla: why the warranty decides it
We fit all three, so this is a genuine comparison, not a sales pitch for one brand over another.

Squeezing every cheap unit
Fox, Octopus and AI grid trading: squeezing every cheap unit
A Fox ESS system pairs well with a time-of-use tariff such as Octopus's off-peak rates. The inverter's AI can charge the battery overnight when electricity is cheap and discharge it through the expensive evening peak automatically, without you having to schedule it manually. It works whether you have solar or not. A battery-only Fox install on a cheap-rate tariff is a genuine, if quote-only, option.

Adam Khodabaccus
We recently had solar panels and battery storage installed at our property in Poole by New Gen Renewables, and I couldn't be more impressed with the service we received. From the very start, the team were incredibly helpful, knowledgeable, and professional. They took the time to explain everything clearly and made the whole process feel smooth and stress-free. We're already seeing the benefits of going solar.
Neil Smith
Great service from New-Gen! Very personal and very reasonably priced. Had 24 panels installed with inverter and 2 batteries. All working perfectly.

We fit all three. Fox ESS gives you a strong warranty at a value price. EcoFlow's 15-year warranty is longer. Tesla suits buyers who want the brand specifically. We'll compare them honestly at survey.
