The all-in-one, explained
Sigenergy SigenStor: the all-in-one, explained
SigenStor combines the battery and inverter into one stackable unit. You can start with what you need now and add more later, up to 120kWh per inverter on larger sites. It's a genuinely different proposition from a fixed-capacity battery, which is why it suits homes planning to expand (an EV, an extension, a home office) and small commercial sites more than it suits a straightforward single-battery domestic install.
What a Sigenergy system costs, and what size you need
SigenStor comes in a range of sizes, from a single domestic unit up to a stacked commercial array. The figures below are our honest starting point, and we size it properly at a free survey.

Is Sigenergy right for you, and when we'd fit EcoFlow or Fox instead
Sigenergy's SigenStor carries a 10-year warranty (30.66MWh throughput per 8.76kWh unit) and stacks to 120kWh per inverter. Here's our honest read on who it actually suits.
Sigenergy is a good fit if
- You want to expand capacity later without replacing the system
- You want to charge an EV directly from the battery stack (integrated DC charging)
- You're sizing a small commercial or critical-power site
We'd steer you elsewhere when
You want the longest available domestic warranty and a simpler single-battery install.
See why we recommend EcoFlowBudget is the deciding factor and you don't need modular expansion.
See the Fox ESS optionYou'd rather keep the battery and inverter separate, with a simple, proven hybrid inverter.

We fit Sigenergy where it genuinely suits, not by default. Ask us honestly at survey which brand fits your actual usage.

Where Sigenergy really shines
Where Sigenergy really shines: expandable to 120kWh, DC EV charging, and retrofit
Beyond the domestic case, SigenStor's genuine edges are its stackability (up to 120kWh per inverter, so a small business or a large home can scale in one system rather than bolting on a second) and its integrated DC EV charging, which draws directly from the battery stack rather than through a separate charger. We also retrofit Sigenergy to existing solar, including systems we didn't install.

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.
What is the Sigenergy SigenStor and how does the all-in-one system work?
It combines the battery and inverter into one stackable unit, expandable up to 120kWh per inverter, so you can start small and add capacity later rather than replace the system.
How much does a Sigenergy system cost to install?
Our general system guide starts from £8,825 including scaffold. A Sigenergy-specific figure depends on the configuration and is confirmed at a free survey.
What battery sizes does Sigenergy come in, and what size do I need?
SigenStor is modular from a single domestic unit up to a stacked 120kWh commercial array. We size it to your annual consumption or load profile at survey.
Is Sigenergy actually right for me, or would EcoFlow or Fox suit my home better?
If you want room to expand later, integrated EV charging, or you're sizing a commercial site, Sigenergy is a strong fit. For a straightforward single-battery domestic install, we'd more often recommend EcoFlow. We'll tell you honestly which suits you at survey.
Can I add Sigenergy to my existing solar, and can it charge my EV?
Yes, we retrofit Sigenergy to existing solar (including systems we didn't install), and SigenStor can charge an EV directly from the battery via its integrated DC charging.
What's the Sigenergy warranty, and how long will it last?
The SigenStor BAT 10 carries a 10-year warranty covering 30.66MWh of throughput on an 8.76kWh unit, genuinely throughput-backed, not just a time limit.
