Battery Storage
Use your solar energy day and night
A home battery stores the solar power you generate during the day so you can use it in the evening — when grid electricity is most expensive. Pair it with a smart tariff and your battery can also charge overnight on cheaper rates.
Why it pays off
Key Benefits
- Use 100% of the solar you produce

Who it's for
Is battery storage right for you?
- Existing solar owners exporting more than they use
- Homes on a smart tariff with cheap night rates
- Households wanting outage backup for essential circuits
- EV drivers wanting to store night-rate charge for peak-time use
Our process
How your battery storage install works
Load & tariff review
We analyse your ESB smart-meter data and current tariff to size the battery properly (5, 10 or 15 kWh).
System design
AC-coupled or DC-coupled with existing solar. Backup circuits selected if required.
Installation (1 day)
Wall or floor-mounted, indoor or outdoor rated. Commissioning and app setup included.
App onboarding
Live charge/discharge monitoring, savings dashboard and automation setup.
Typical pricing
Battery price depends on capacity, brand and whether it's paired with new solar or retrofitted. We size and quote a fixed price after reviewing your ESB bill and existing inverter.
Estimated figures only. Savings, payback, generation and running-cost numbers shown are indicative estimates, not guarantees. Actual results depend on your system size, roof orientation, shading, electricity tariff, self-consumption, grant eligibility, property condition and other factors.

Frequently asked
Battery Storage FAQ
How long does a home battery last?
10-year manufacturer warranty is standard, with 6,000+ cycles at 80% depth-of-discharge. Real lifespan is 12–15 years for LiFePO4 chemistry we use.
Can a battery power my house during a power cut?
Yes, with the backup module option — essential circuits (fridge, lights, sockets, boiler pump) can run for 12–24 hours depending on capacity. Whole-home backup is possible with larger systems.
Do I need solar to have a battery?
No. Battery-only installs on a night-rate tariff (e.g. EV night rate at 8c vs day 40c) can save €500–€800/year by shifting all daytime use to overnight charge.
Is a battery safe indoors?
Yes. LiFePO4 chemistry (what we install) is non-flammable and thermally stable. Units are IP65-rated for garage, utility or outdoor mounting.
How much does a battery add to solar savings?
Typically €300–€600/year on top of solar-only savings, plus €150–€400/year from night-rate arbitrage on smart tariffs.
