💡 Most popular Irish combination in 2026: LONGi Hi-MO 6 panels + compatible hybrid inverter + Huawei Luna2000 10kWh — installed by a SEAI-registered contractor, managed by a smart energy controller.
🧠 Energy Management Systems — get more from your battery
A battery stores your solar energy — an energy management system makes sure it's used at the right time. EMS devices can reduce grid import by an additional 10–25% beyond the battery alone by coordinating solar generation, battery charge/discharge, hot water heating and EV charging. See the full Smart Energy Directory for all EMS products available in Ireland.
💡 Why add an EMS to your battery system? Without an EMS, a battery charges and discharges on simple rules (charge during solar generation, discharge at night). An EMS adds smart scheduling — learning your consumption patterns, responding to time-of-use tariffs (e.g. Electricity Ireland Smart), and diverting surplus to hot water or EV charging before exporting to the grid.
🌡️ Pair with a heat pump — the night-rate combination
A solar battery and a heat pump are the most powerful combination for cutting your heating bill. Your battery charges overnight at the cheap night rate — then your heat pump runs from stored electricity during the day, delivering heat at a fraction of the cost of gas or oil.

🔌 Pair with an EV charger — charge your car from stored solar
A home battery and an EV charger complete your home energy system. Store surplus solar in your battery, then draw it back through a smart charger to power your car — maximising self-consumption and cutting your fuel bill to near zero.
🔌 Battery + EV charger: the perfect home energy pair
Your battery stores surplus solar during the day. A smart solar-compatible charger like the myenergi Zappi draws from your battery first — so your car charges on energy you generated for free. At night, the battery tops up on cheap off-peak rates (as low as €0.10/kWh) for the next day's driving. SEAI Home Charger Grant: €300 applies to eligible wallbox installations.
❓ Luna2000 10kWh — frequently asked questions for Irish buyers
The Huawei Luna2000 10kWh is priced at approximately €4,200 for the 10kWh configuration. For 10kWh (2 × 5kWh modules). 5kWh single module ~€2,300. Installed cost varies by county, property type, and whether this is a new solar installation or a retrofit. The SEAI Solar PV Home Grant (up to €1,800) applies to solar panel components when installed at the same time — get 3 quotes from SEAI-registered installers for an accurate all-in system price.
For a typical Irish home with €0.33/kWh electricity and a 4kWp solar system, the Huawei Luna2000 10kWh (10kWh usable) shifts approximately 2,738 kWh/year from grid import to self-consumed solar — saving around €964/year. At €4,200, the estimated battery-only payback is ~4.4 years. An energy management system (EMS) can improve self-consumption by a further 10–25%, shortening the payback period.
The Huawei Luna2000 10kWh carries a 10-year warranty that guarantees at least 70% of the original capacity remains after 10 years of normal use — the standard industry capacity retention guarantee. The warranty covers manufacturing defects and capacity degradation below the 70% threshold. Annual cycling beyond the rated 6,000 cycles, physical damage or installation errors are not covered. Always register the battery with Huawei at installation to activate the warranty.
LFP (Lithium Iron Phosphate) is now the dominant battery chemistry for Irish residential and commercial solar storage for good reasons. It is the safest chemistry — LFP cells have an extremely low thermal runaway risk compared to older NMC or NCA chemistries. It has a longer cycle life — the Huawei Luna2000 10kWh is rated for 6,000 cycles, equivalent to 16 years of daily cycling. LFP tolerates Ireland's variable temperatures better than NMC, and it handles deep daily discharge without the capacity fade that affects other chemistries. For Irish homeowners cycling the battery every day, LFP is the right choice.
Yes — the Huawei Luna2000 10kWh provides Full backup (with Huawei SUN2000 hybrid inverter). When the grid goes down, the system automatically switches to battery-backed island mode, keeping your household circuits live. Switchover time is typically under 20ms — fast enough that most equipment, including computers, does not notice the transition. Backup is managed through the FusionSolar. Note: backup capability requires the system to have been correctly configured for island mode at installation — confirm this with your installer.
No — the Huawei Luna2000 10kWh uses proprietary communication protocols and is only compatible with Huawei inverters. It cannot be used with Solis, Sungrow, GoodWe, Growatt, Fronius or SolarEdge inverters. If you do not have or plan to install a Huawei inverter, see the Battery Directory to find a battery compatible with your inverter. Multi-inverter batteries like the Pylontech US3000C (Solis, Sungrow, GoodWe, SMA) or BYD Battery-Box (Fronius, SolarEdge, SMA) offer more flexibility.
Yes — the Huawei Luna2000 10kWh is modular and expandable from 5kWh to 30kWh in 5kWh increments, without replacing the inverter or rewiring the solar system. This is a significant advantage for homeowners who want to start with a smaller capacity and expand as their budget allows or as electricity prices change. Your installer can add modules at any point after initial installation — though it's worth having the mounting and wiring provisioned for expansion at the original installation to reduce future labour costs.
Not directly. The SEAI Solar PV Home Grant of up to €1,800 applies to the total installed cost of the solar PV system — panels, inverter, mounting hardware, cabling and labour. It does not cover battery storage as a standalone item. However, if battery storage is installed as part of a new solar system at the same time, the grant still applies to the solar components, and the overall system cost (including battery) is reduced by €1,800. Some homeowners maximise their panel and inverter specification under the grant, then use the savings to partially offset the battery cost. Always apply to SEAI and receive a Letter of Offer before installation begins.
The Huawei Luna2000 10kWh is rated for 6,000 charge/discharge cycles. At one full cycle per day — typical for a solar-charged battery in Ireland — this represents approximately 16 years of daily cycling before reaching end-of-life capacity (defined as capacity dropping below 70% of original). Most Irish homeowners cycle batteries to 60–80% depth per day rather than 100%, which extends effective lifespan further. The 10-year warranty provides protection during the early years. Budget for potential replacement at year 15–20 when modelling long-term system financials.
Three factors: the Huawei SUN2000 inverter is Ireland's most-installed residential hybrid, the Luna2000 is the only battery compatible with it (creating automatic ecosystem demand), and the FusionSolar monitoring integration is the tightest and best-rated in the residential market. Irish installers stock Luna2000 as their default Huawei-ecosystem battery, so supply and installer familiarity are very strong.
No — the Luna2000 is exclusively compatible with Huawei SUN2000 hybrid inverters (residential) and Luna2000-S commercial systems. It is not compatible with any third-party inverter from Solis, Sungrow, GoodWe, Fronius or any other brand. If you want battery flexibility across multiple inverter brands, consider Pylontech US3000C (compatible with Solis, Sungrow, GoodWe, Growatt) or BYD Battery-Box (compatible with Fronius, SolarEdge, SMA).
Yes — when paired with a Huawei SUN2000 hybrid inverter, the Luna2000 provides full home backup capability. During a grid outage, the system automatically switches to battery-backed island mode, keeping your household circuits live. The switchover time is typically under 20ms — fast enough that most equipment, including computers, does not notice the transition.
