GivEnergy Battery Review: Is It Good for Ireland?
GivEnergy is a UK home-energy brand making lithium iron phosphate (LFP) batteries in both All-in-One and modular formats, popular for AC-coupled retrofits and new hybrid installs. Here's our independent review of the GivEnergy battery range for Irish homes, covering specs, the GivEnergy monitoring app, warranty, and how it compares to the Tesla Powerwall and other solar battery brands we track. For the wider picture, see our guide to solar battery storage in Ireland.
Quick Answer
GivEnergy is a UK manufacturer of LFP (lithium iron phosphate) home batteries available in Ireland in All-in-One and modular sizes from roughly 3.3kWh up to 13.5kWh. It is a popular choice for AC-coupled retrofits to existing solar as well as new hybrid installs, paired with a well-regarded free monitoring app that supports time-of-use tariff charging. The All-in-One carries around a 12-year warranty.
Who Are GivEnergy?
GivEnergy is a UK home-energy company that designs and supplies solar battery storage, hybrid inverters, and an AC-coupled battery system for retrofitting to existing solar arrays. They don't make solar panels themselves — instead they make the battery and inverter hardware that pairs with any brand of panel.
Their batteries use LiFePO4 (lithium iron phosphate) cells, the same chemistry favoured for its safety and long cycle life. GivEnergy is widely installed across the UK and is available through Irish installers, with a particular strength in retrofit jobs where a homeowner already has solar panels but no storage. The free GivEnergy app is one of the most praised parts of the package for its granular monitoring and tariff-based charging control.

The GivEnergy Battery Range
GivEnergy splits its home storage into an integrated All-in-One unit and a modular range you can size to your needs. Capacities run from around 3.3kWh up to 13.5kWh, all using LFP cells.
All-in-One
An integrated unit combining battery, inverter, and control in a single enclosure. Typically around 13.5kWh of usable storage and the longest warranty in the range (around 12 years). A tidy option for whole-home backup and self-consumption.
Modular Batteries
Standalone LFP battery units in roughly 3.3kWh, 5.2kWh, and 9.5kWh sizes. You pick the capacity that suits your usage and pair it with a GivEnergy hybrid inverter. The 9.5kWh module is a common sweet spot for Irish family homes.
AC Battery (Retrofit)
An AC-coupled variant that retrofits to an existing solar system without replacing your current inverter. Ideal if you already have panels and just want to add storage to capture surplus generation instead of exporting it.
GivEnergy Battery Specifications
| Specification | Value |
|---|---|
| Battery Chemistry | LiFePO4 (lithium iron phosphate) |
| All-in-One Capacity | Around 13.5kWh usable |
| Modular Capacities | 3.3kWh / 5.2kWh / 9.5kWh / 13.5kWh |
| Coupling | Hybrid (DC) or AC-coupled retrofit variant |
| Inverter | GivEnergy hybrid inverter (sold with hybrid systems) |
| Monitoring | Free GivEnergy app (iOS / Android) |
| Tariff Charging | Yes — time-of-use / dynamic tariff scheduling |
| All-in-One Warranty | Around 12 years |
| Retrofit Friendly | Yes — AC battery adds to existing solar |
| Best For | AC-coupled retrofits and new hybrid installs |
Exact usable capacity, depth of discharge, and round-trip efficiency vary by model and revision. Always ask your installer for the model-specific datasheet before ordering, and confirm the warranty terms for the unit being quoted.
GivEnergy vs Tesla Powerwall 3 and Pylontech: Which Is Better?
| Feature | GivEnergy | Tesla Powerwall 3 | Pylontech |
|---|---|---|---|
| Capacity | 3.3–13.5kWh | 13.5kWh (fixed) | ~2.4kWh+ stackable modules |
| Chemistry | LFP | LFP | LFP |
| Built-in Inverter | Yes (All-in-One / hybrid) | Yes | No (needs third-party hybrid inverter) |
| Retrofit Path | Yes (AC battery variant) | Yes (AC-coupled) | Depends on paired inverter |
| Monitoring App | Free, granular, tariff control | Tesla app, polished | Via paired inverter brand |
| Warranty | ~12 years (All-in-One) | 10 years | ~10 years (varies) |
| Best For | Flexible sizing & retrofits | One-box whole-home backup | Budget mix-and-match builds |
Verdict: GivEnergy wins on flexible sizing and its retrofit-friendly AC battery, plus a well-liked free app with strong tariff control and a long All-in-One warranty. Tesla Powerwall 3 is the simplest one-box option with strong brand recognition and proven whole-home backup. Pylontech is the budget, mix-and-match choice but relies on a separately chosen hybrid inverter and its app. For an Irish home adding storage to existing panels, GivEnergy's retrofit path is a genuine advantage.
GivEnergy: Frequently Asked Questions
Is GivEnergy available in Ireland?
Yes. GivEnergy batteries are supplied and installed in Ireland through solar installers. Ask your installer whether they offer GivEnergy and whether they recommend the All-in-One or a modular configuration for your home.
What capacities does the GivEnergy battery come in?
GivEnergy offers LFP storage in modular sizes of roughly 3.3kWh, 5.2kWh, 9.5kWh and 13.5kWh, plus an integrated All-in-One unit at around 13.5kWh usable. The 9.5kWh module is a common choice for Irish family homes.
Can GivEnergy be retrofitted to my existing solar panels?
Yes. GivEnergy makes an AC-coupled battery variant designed to retrofit to an existing solar system without replacing your current inverter. This lets you store surplus generation instead of exporting it, which is one of GivEnergy's main strengths.
What warranty does GivEnergy offer?
The GivEnergy All-in-One carries around a 12-year warranty. Warranty terms vary by model and revision, so confirm the exact coverage for the specific unit your installer is quoting before you order.
Is the GivEnergy app any good for time-of-use tariffs?
Yes. The free GivEnergy monitoring app is well regarded for its granular data and its dynamic, time-of-use charging control. In Ireland, with a smart meter and a night-rate or time-of-use tariff, you can schedule the battery to charge from the grid when electricity is cheapest and discharge during peak hours.
