Buy Huawei Battery – Fast Charging & Extended Battery Life
A Huawei battery stores the solar power your panels make during the day so you can use it in the evening, when grid electricity is dearest. Added to a solar PV system, it cuts how much you import from the grid night after night.
Since 6 October 2026 there is a stronger reason to add storage. The SEAI now pays a flat €600 towards a home battery of 5 kWh or larger, fitted by a registered solar PV company as part of a solar system.
Our engineers size the unit, confirm your system is ready for it, and handle the grant from offer to payment.
What a Huawei Battery Does in a Solar System
A Huawei battery is a lithium iron phosphate storage unit that captures surplus solar generation and releases it on demand. During daylight your panels often make more than the house uses. Rather than export that surplus for a low rate, the unit holds it for the evening peak.
The LUNA2000 range is modular, so capacity can be matched to your usage and added to later. It pairs with a compatible hybrid inverter and reports charge, output and household use through a monitoring app.
It suits both homes and commercial sites, and it is the cleanest route to adding storage to an existing system without replacing what you already have.
- Stores daytime surplus instead of exporting it cheaply
- Powers the evening peak from your own generation
- Scales up in modules as your needs grow
- Tracks performance live through the app
How the €600 SEAI Grant Works With a Home Battery
The SEAI pays a flat €600 towards a home battery of at least 5 kWh, whether you are adding storage to an existing solar system or installing both together.
Your home must have been built and occupied before 2025, and the work must be done by an SEAI-registered solar PV company. The published SEAI battery grant criteria set out the detail, and we confirm your eligibility before quoting.
| Condition | What the grant requires |
|---|---|
| Grant amount | Flat €600, regardless of what the battery costs |
| Battery size | 5 kWh or larger, smaller units do not qualify |
| Your home | Built and occupied before 2025, with an MPRN |
| Installer | An SEAI-registered solar PV company |
| Timing | Grant offer approved before any work starts |
| Pairing | Fitted with a solar PV system, new or existing |
We are SEAI-registered and manage the whole application for you, part of the end-to-end solar grants we administer, so the €600 is secured without you chasing forms. A battery grant can only be claimed once per home, so it is worth sizing the unit properly the first time.
Why Pair a Huawei Battery With Your Panels
Storage lifts how much of your own solar you actually use. Without it, much of your midday surplus is exported for a low rate and you still buy expensive units after dark.
A battery keeps that energy for the evening, so you draw far less from the grid at peak times, and lean on night-rate charging only when it pays.
To see how storage changes your own numbers, size a system and run your usage through the calculator below.
What Homes and Businesses Gain
- More of each day’s free solar used in your own home
- Lower evening grid imports when unit rates are highest
- Backup to key circuits during an outage when configured for it
- A clearer path to energy independence as tariffs move

Will a Huawei Battery Suit Your Home or Business?
Most homes and many commercial sites can take one, provided the solar system has a compatible hybrid inverter. A standard string inverter on its own will not charge a battery, so an older system sometimes needs an inverter change, which our engineers check during the survey before anything is quoted.
The grant needs a battery of at least 5 kWh. Most configurations we fit sit comfortably above that, and the modular design means you can start with what you need today and add capacity later as your usage grows or an EV joins the household.
How to Add a Huawei Battery and Claim the Grant
Adding storage with the grant handled runs as a straightforward five-step process, with the SEAI paperwork done on your behalf at every stage.
- Free survey. We check your roof, usage and existing inverter to confirm what your system needs.
- Custom sizing and quote. We design the storage to your demand and give you a clear price.
- Grant offer secured. We submit the SEAI application and wait for approval before any work begins.
- Installation. The unit is fitted, commissioned and set up on the monitoring app, often in a single day for a retrofit.
- Grant applied. The €600 is processed through the SEAI once the install is verified.
Conclusion
Adding storage is the step that makes a solar system earn its keep after dark, and the €600 grant takes the edge off the cost.
