In short: Growatt is a reliable, widely used inverter — and we arrange your full 10-year warranty
We now supply Growatt as well: one of the world’s largest and most-installed inverter brands, with a strong reputation for reliability. We offer it on single and three phase, on a low-voltage battery (48 V), and we make sure you get the full 10-year warranty — with the option to extend to 15 or 20 years.
Why we supply Growatt
Growatt sits in the worldwide top 4 of inverter manufacturers: millions of installations and years of reputation as a solid, dependable inverter. We choose our inverters case by case — the right type for each home — and Growatt earns its place on what it can do:
- Rugged and weatherproof — the housing is IP65, so it can go outdoors, in a garage or a shed.
- Fast backup — if the grid drops out, it switches to the battery in about 10 milliseconds; fast enough that your appliances simply keep running.
- Flexible to connect — suitable for a new installation and for expanding an existing system.
- Everything in view — yield, battery level and consumption are all in Growatt’s own app.
And because Growatt works on a low-voltage battery (48 V), you can pair almost any battery brand with it — a safe, universal battery class.
Which Growatt do we offer on single-phase?
Growatt’s single-phase range is broad, so we’ve narrowed it to the current, modern series — the SPM. Two sizes cover the home:
- SPM 3000-6000TL-HU — 3 to 6 kW, for the ordinary home.
- SPM 8000-10000TL-HU — 8 to 10 kW, for the larger home; with three MPPT inputs it gets more out of a roof with panels facing different directions.
Both are hybrid (ready for a home battery) and run on the universal 48 V battery. We deliberately leave out the older Growatt models — they’ve been superseded by this newer SPM line, so you always get the current generation.

10-year warranty — as standard, and we handle the rest
With an inverter, the warranty counts:
- Up to 20 kW — all our single-phase models and most of the three-phase — you get 10 years of factory warranty as standard.
- Only the heaviest three-phase models (above 20 kW) carry a 5-year base; we extend those to 10 years free of charge by registering your system in time — we handle it, you needn’t do a thing.
- Want to be covered even longer? The warranty extends to 15 or 20 years (purchasable).
So your Growatt carries a full 10 years of warranty, and more if you want it.
Three-phase too
Do you have a three-phase connection, a larger home or a small business? Then we offer the Growatt WIT line: a three-phase hybrid on the same low-voltage battery (48 V), from an ordinary three-phase home up to substantial power — 4 to 25 kW. Rugged (IP66), with fast backup, and 100% unbalanced load capability (each phase individually loadable to full power) — so during a cut your home simply keeps running, even when consumption is spread unevenly across the phases.
What we do for you
We’ll advise you honestly on whether Growatt suits your home and your plans, fit it properly, and handle the warranty registration so you have those 10 years without any fuss.
Where Growatt particularly earns its place: outdoor positions, garages and sheds (IP65, and IP66 on the three-phase), homes where the switchover to battery has to be quick, and expanding an existing installation — it’s flexible to connect into what’s already there. And if your consumption is spread unevenly across the phases, the WIT line’s 100% unbalanced-load capability is the reason we’d put it forward.
Request your free, no-obligation quote — free and no obligation. We’ll look together at whether Growatt is the best choice for you, and we’re perfectly happy to point you elsewhere if it isn’t.
