Three platforms, chosen not stocked
We install three home battery systems in Northern Ireland: the Hinen A Series, the Sigenergy SigenStor and the EcoFlow PowerOcean. All three are LiFePO₄ chemistry, all three do backup, all three are modular. They suit different houses, and this is how we actually pick between them.
Hinen A Series — all-in-one, sensible money
- 3.6–6 kW hybrid inverter and a 14.4 kWh battery in one slim stack, 18 cm deep — no separate boxes, no wall of conduit.
- Expands to 86.4 kWh per inverter (six battery clusters), and up to six inverters in parallel.
- Backup switchover of 10 ms or less with a built-in bypass switch; self-heating cells rated to −20 °C.
- New to the UK in 2026 from a manufacturer with more than 20 years of battery production; we're among the first NI installers fitting it.
Who it suits: most homes. A big single battery at a strong price — it's the platform in our Smart Energy System from £6,750 (solar and battery together). If you want serious capacity without paying flagship money, start here.
Sigenergy SigenStor — the five-in-one flagship
- Hybrid inverter, battery modules, backup, energy management and an optional EV DC charging module in one tower.
- Stacks to 48 kWh per tower; packs click together and can be added years later, mixed capacities included.
- Load-side switchover rated at 0 ms — backed-up circuits don't flicker. IP66, so it can live outside on a wall.
- 10-year battery warranty; built for V2H/V2G pending the standards.
Who it suits: homes that want one system to run the house and the car — the DC charging module charges the EV straight from the battery and panels — and anyone who wants whole-home backup done properly. The premium choice.
EcoFlow PowerOcean — start small, longest warranty
- Start with one 5 kWh pack and grow to 45 kWh; each pack has its own DC-DC converter, so new packs work beside old ones.
- 15-year warranty to 70% capacity, backed by a 6,000-cycle design — the longest we install, registered in your name at handover.
- Backup as standard with a switchover designed to go unnoticed; three-phase systems up to 12 kW of backup output.
Who it suits: people who want to begin modestly and add capacity as the EV or heat pump arrives, and anyone who values the longest written warranty.
How to choose
- Usage first. We size from your real consumption and your solar generation, not from the biggest box. Hinen's 14.4 kWh single module covers a typical NI household in one go; SigenStor and PowerOcean get there in modules.
- Backup. All three do it. If you want the whole house carried through a cut without a flicker, SigenStor; for essentials circuits any of them.
- EV. A SigenStor with the DC module is the tidiest one-box answer; otherwise any battery pairs with a solar-aware charger.
- Growth. PowerOcean and SigenStor grow in small steps; Hinen grows in 14.4 kWh clusters.
- Warranty. 10 to 15 years across the range; PowerOcean longest.
- Budget. Hinen for value; SigenStor and PowerOcean in the Premium Home Energy System, priced at survey.
True of all three
0% VAT until 31 March 2027 — including a battery added to existing solar (standalone batteries have qualified since 1 February 2024). Installed and certified by NICEIC electricians, warranties registered in your name, monitoring app handed over working. And a straight recommendation: we'll tell you which one fits your house rather than whichever has the best margin. Battery storage has the full comparison and the survey booking.
Questions people ask
Which home battery is best in Northern Ireland?
It depends on the house. Hinen A Series for the most capacity per pound, Sigenergy SigenStor for a one-box house-plus-EV system with seamless backup, EcoFlow PowerOcean for starting small with the longest warranty. We install all three and recommend from your usage.
What size home battery do I need?
We size from your actual consumption and generation at the free survey rather than guessing. Hinen's 14.4 kWh module covers a typical household in one go; the modular systems build up in 5 kWh or similar steps.
Can I add a battery to solar panels I already have?
Yes — AC-coupled beside your current inverter or by swapping to a hybrid inverter, and it's 0% VAT until 31 March 2027.
Will a home battery keep my power on in a cut?
With the right system and a backup circuit design, yes. Hinen switches in 10 ms or less, SigenStor is rated at 0 ms on the load side, and PowerOcean's switchover is designed to go unnoticed.
