💰
Cost-effective entry to 20kWh commercial storage
At ~€8,000 for 20kWh, the SBH is the most affordable commercial LFP option in this directory by capacity — a lower upfront investment for SMEs and farms wanting to store peak solar generation without committing to a 25–38kWh system.
🚐 Electrify your fleet — overnight depot charging from your battery
Commercial battery storage and an electric fleet are the ideal pairing. Solar charges your battery during the day; your fleet charges overnight at your depot from stored energy. SEAI van grants of €7,600 per vehicle stack on top of your battery grant. See the full EV Vehicle Directory — 205+ vehicles including vans, trucks and buses.
🔋 Commercial battery + electric fleet — depot charging at near-zero cost
A commercial battery system stores daytime solar generation for overnight fleet charging. Vans charge from stored solar at your depot during off-hours — at near-zero fuel cost. SEAI offers €7,600 per vehicle in van grants, stackable on top of your battery and solar grants. Accelerated Capital Allowance applies to all three technologies in year one.
📊 Example depot: 50kWh commercial battery + 50kWp solar + 10 × electric vans = solar charges battery by day, battery charges fleet by night. Annual fleet fuel cost: near zero.

The SBH 20kWh (HV Commercial) is compatible with the following inverters. Click any inverter to see full specifications, pricing and system cost estimates. See the Solar Inverter Directory to compare all 15 inverters available in Ireland.
⚠️ Ecosystem note: The SBH 20kWh (HV Commercial) is only compatible with Sungrow inverters. If you are considering a different inverter brand, please check the Battery Directory for a battery compatible with your inverter.
☀️ Compatible solar panels
The SBH 20kWh (HV Commercial) is compatible with all solar panel brands available in Ireland — any panel that works with your compatible inverter will work with this battery. See the Solar Panel Directory to compare all 13 panels with specifications, pricing and SEAI eligibility.
Compatibility is via the inverter - ensure your chosen inverter is compatible with both your panels and this battery. All panel links above go to their individual review page.
🔧 Complete your solar system
The SBH 20kWh (HV Commercial) 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.
The Sungrow SBH 20kWh (HV Commercial) is priced at approximately €8,000 for the 20kWh configuration. For the 20kWh SBH unit. Sungrow SH10RT 3-phase inverter required separately (~€3,200). SEAI TAMS / non-domestic grants may apply. 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 Sungrow SBH 20kWh (HV Commercial) (18.6kWh usable) shifts approximately 5,092 kWh/year from grid import to self-consumed solar — saving around €1,792/year. At €8,000, the estimated battery-only payback is ~4.5 years. An energy management system (EMS) can improve self-consumption by a further 10–25%, shortening the payback period.
The Sungrow SBH 20kWh (HV Commercial) 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 Sungrow 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 Sungrow SBH 20kWh (HV Commercial) 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 Sungrow SBH 20kWh (HV Commercial) provides Full backup (with Sungrow SH10RT 3-phase 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 iSolarCloud Commercial. Note: backup capability requires the system to have been correctly configured for island mode at installation — confirm this with your installer.
No — the Sungrow SBH 20kWh (HV Commercial) uses proprietary communication protocols and is only compatible with Sungrow inverters. It cannot be used with Huawei, Fronius, Solis, GoodWe or SolarEdge inverters. If you do not have or plan to install a Sungrow 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.
Commercial installations using the Sungrow SBH 20kWh (HV Commercial) 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 20kWh system at ~€8,000, the ACA alone could reduce the effective cost by €1,000–€2,000 in year one for a profitable business. Always verify current eligibility at seai.ie and revenue.ie before proceeding.
The Sungrow SBH 20kWh (HV Commercial) 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.
The Sungrow SBH 20kWh is a single fixed-capacity high-voltage cabinet — 20kWh, floor-standing, not expandable, paired exclusively with the SH10RT 3-phase inverter. The Sungrow SBR256 is a modular system starting at 9.6kWh and expandable to 100kWh by adding 3.2kWh modules. Choose the SBH if you need exactly 20kWh at lower cost and do not anticipate expanding. Choose the SBR256 if you need a scalable system that can grow with your solar generation.
Three main support mechanisms apply: (1) SEAI Non-Domestic Microgen grant — covers commercial solar and storage for premises up to 6MW. Verify current battery-specific eligibility at seai.ie before proceeding. (2) TAMS III — agricultural premises with qualifying solar + storage installations may access up to 60% grant aid. Confirm current TAMS III battery eligibility with your Teagasc advisor. (3) Accelerated Capital Allowance (ACA) — the full capital cost of eligible energy-efficient equipment can be written off against corporation tax in year one. Battery storage systems listed under the ACA scheme qualify; confirm the SBH is on the current ACA list at revenue.ie.
