🔧 Complete your solar system
The Luna2000-S 100kWh is Step 4 - you need solar panels and a compatible inverter before it, and an energy management system after it to get the maximum return from every kWh.
💡 Commercial tip: LONGi Hi-MO 7 (580W) or JinkoSolar Tiger Neo (580W) are the most common panel choices for Irish commercial solar + storage systems. Fewer panels per kWp reduces mounting and labour cost at scale.
🧠 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
Commercial battery storage and a heat pump cut heating costs across premises of any size. Charge the battery on cheap night-rate electricity, run the heat pump from stored power during peak hours — and claim SEAI grants on both systems. Browse all heat pumps →

At a SCOP of 4.3, every €1 of night-rate electricity stored in your battery produces €4.3 worth of heat from the heat pump. That makes battery-powered heat pump operation 3× cheaper per kWh of heat than a gas boiler at today's rates. Stack the SEAI battery grant with the up to €12,500 heat pump grant for maximum combined subsidy.
🔌 Pair with fleet EV chargers — charge your vehicles from stored solar
Commercial battery storage paired with fleet EV chargers is the most cost-effective way to run an electric fleet. Your solar charges the battery during the day; your fleet charges from stored energy overnight at solar rates.
🔌 Commercial battery + fleet charging: close the loop on solar
A commercial battery stores your daytime solar generation. Fleet chargers draw from that stored energy overnight — so your vans charge on solar you generated for free rather than expensive grid electricity. Dynamic load balancing ensures multiple charge points share your available supply without expensive grid upgrades.
❓ Luna2000-S 100kWh — frequently asked questions for Irish buyers
The Huawei Luna2000-S 100kWh is priced at approximately €42,000 for the 100kWh configuration. Indicative for 100kWh system. Larger configurations quoted on application. 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-S 100kWh (100kWh usable) shifts approximately 27,375 kWh/year from grid import to self-consumed solar — saving around €9,636/year. At €42,000, 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-S 100kWh 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-S 100kWh 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-S 100kWh provides Full commercial backup capability. 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 Commercial. 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-S 100kWh 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-S 100kWh is modular and expandable from 50kWh to 1000kWh in 50kWh 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.
Commercial installations using the Huawei Luna2000-S 100kWh may qualify for several support schemes: the SEAI Non-Domestic Microgen grant (confirm current battery-specific eligibility at seai.ie); TAMS III providing up to 60% grant aid for qualifying agricultural buildings with solar and storage; and Accelerated Capital Allowance (ACA) through Revenue allowing the full equipment cost to be written off against tax in year one. For a 100kWh system at ~€42,000, the ACA alone could reduce the effective cost by €5,250–€10,500 in year one for a profitable business. Always verify current eligibility at seai.ie and revenue.ie before proceeding.
The Huawei Luna2000-S 100kWh 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.
For C&I installations of this scale, the most relevant supports are: SEAI Non-Domestic Microgen grant (confirm current eligibility for ESS-only installations at seai.ie); Accelerated Capital Allowance — the full capital cost written off against corporation tax in year one (applies to battery storage under the ACA energy-efficient equipment list); Enterprise Ireland and IDA supports for manufacturing and FDI clients; TAMS III for qualifying agricultural installations. At €42,000+ system cost, the ACA tax benefit alone can amount to €8,000–12,000 in year-one tax reduction for a profitable business.
