Battery storage — NI
Store it when it's cheap. Use it when it's not.
A battery turns your solar surplus — or cheap overnight electricity — into power you use at peak rates. We install Hinen, Sigenergy and EcoFlow systems across Northern Ireland, all 0% VAT.
Glow Electric installs home battery storage across Belfast and Northern Ireland — Hinen A Series, Sigenergy SigenStor and EcoFlow PowerOcean, all LiFePO₄ with 10 to 15 year warranties. Solar plus battery from £6,750 installed at 0% VAT, and batteries can be added to existing solar. NICEIC electricians, free survey, fixed quote.

Why a battery
Three ways a battery earns its keep.
A normal day at home: the roof peaks at lunchtime, the house peaks at teatime. A battery is what connects the two.
-
Self-use beats export
Keep your solar
Without storage, your surplus is exported for pence while you buy evening power at full rate. A battery keeps the difference in your pocket.
-
Cheap rate in, peak rate out
Buy cheap, use peak
Low overnight tariffs exist for a reason. Charge the battery while you sleep and run the house on it when rates triple at teatime.
-
Backup built in
Ride out power cuts
With a backup-capable system, the kettle still boils when the street goes dark.

All-in-one hybrid systems from a manufacturer with 20+ years behind it — we're among the first installers fitting Hinen in Northern Ireland.
Flagship
Sigenergy SigenStor
The five-in-one tower — inverter, battery and optional EV DC charging in modular stacks that grow with you.
Longest warranty
EcoFlow PowerOcean
Clean, quiet home storage with the longest battery warranty we install — fifteen years, in writing.
Not sure which? That's the point of the survey — sizing and platform recommendation are free.
Sizing it right
Bigger isn't better. Right is better.
An oversized battery wastes capital sitting half-charged; an undersized one leaves you buying peak electricity anyway. We size from your actual usage pattern — smart meter data if you have it, a proper conversation if you don't. Evening load, EV, heat pump plans, tariff options: it all goes into the sizing.
- Modular platforms. Start sensible, add capacity later if your usage grows.
- Retrofit friendly. Already have panels? We add storage to existing arrays.
- 0% VAT. Battery storage qualifies as an energy-saving material — 0% VAT until 31 March 2027, then 5%.
Can I add a battery to my existing solar panels?
Yes. We retrofit batteries to existing arrays either AC-coupled alongside your current inverter, or by swapping to a hybrid inverter — the survey tells us which makes better sense for your setup.
How long do home batteries last?
The systems we install carry 10 to 15 year warranties, and all use LiFePO₄ chemistry — the long-life, stable battery type. Realistically you're buying a system designed to outlast its payback period several times over.
Where does the battery go?
Usually a garage, utility room or well-ventilated storage space near your consumer unit. They're wall or floor mounted, quiet, and sized like a small radiator to a tall fridge depending on capacity.
Is a battery worth it without solar?
Often, yes. On the right tariff a battery charges cheap overnight and runs the house at peak rates. If you have an EV tariff already, the numbers usually get better again. We'll model it before you buy.
