Is Sunsynk any good, and is it right for your home?
Yes, Sunsynk is a genuinely capable, reliable inverter and battery platform. We use it deliberately, not as a fallback. Here's the honest picture on fit.
Sunsynk is a good fit if
- You need an off-grid-capable inverter (no mains connection at all)
- You're sizing a commercial or critical-power site
- You want a generator-integrated backup system
We'd more often recommend elsewhere when
You want a straightforward domestic battery with the longest warranty.
See why we recommend EcoFlowBudget is the deciding factor for a standard home install.
See the Fox ESS optionYou want a straightforward grid-tied hybrid inverter, not an off-grid or commercial-scale setup.
See the Solis option
On reliability doubts: like most manufacturers in this market, Sunsynk is designed and engineered internationally with UK distribution. We only fit it because the inverters we've installed have proven reliable on real commercial and off-grid jobs.
The kit we install
The Sunsynk kit we install, and the truth about reliability
We use Sunsynk's rack-mounted batteries and off-grid-capable hybrid inverters, including 30kW commercial units, built around individual high-voltage battery modules stacked into racks rather than a single fixed-size box. It is a deliberately utilitarian setup, chosen for sites that need to stay running rather than for how it looks on a wall, and we fit gateways and generator integration wherever a site genuinely cannot afford downtime. On the "common Sunsynk problems" people ask about online: like any inverter brand, issues are almost always down to poor commissioning or an undersized system, not the hardware itself, which is exactly why we spec and commission every install ourselves rather than drop-shipping a kit.

Cost & what's included
What a Sunsynk system costs and what's in it
Sunsynk installs are commercial and off-grid by nature, so pricing is scoped individually against your site's load, generator integration and battery capacity rather than a fixed domestic figure.
Real local proof
A real Sunsynk build: off-grid near Dorchester
We fitted 2× Sunsynk 30kW inverters on a genuinely off-grid site near Dorchester, replacing a diesel generator that had been running a workshop, a school facility, cabins and a glamping field. 120 panels feed 12 high-voltage batteries across two expandable racks, and the generator is configured to auto-kick-in at 12% battery, sync, and hand back over automatically at 10%, so power never actually drops. All the roof work was done in 3 days, and the racks are built to expand again when a second barn is added. It's the kind of job Sunsynk is built for, and one a national brand page can't localise.

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.
Is Sunsynk actually any good, and is it right for my home?
Yes, it's a genuinely capable platform, but we use it mainly for commercial and off-grid sites, not as our default domestic battery. For a standard home install, we'd usually point you to EcoFlow or Fox ESS first.

What are the common Sunsynk problems, are the inverters reliable long-term?
Reliability issues with any inverter brand are almost always down to poor commissioning or an undersized system, which is why we spec and commission every Sunsynk install ourselves rather than drop-shipping a kit.
Sunsynk vs the alternatives, is it better than Victron, or should I have EcoFlow/Fox instead?
Sunsynk and Victron both suit off-grid and commercial sites. For a straightforward home battery we'd recommend EcoFlow (15-year warranty) or Fox ESS (value option) instead.
