Huawei has announced that its SUN2000 series is the most-installed solar inverter in Ireland in 2026. The company offers two main variants: the L1 hybrid model, which is battery-ready, and the M0 string-only inverter, which costs roughly €300 less. The SUN2000-6KTL-L1 is the most common model in the country, according to Huawei.

The inverter's technical specifications include a maximum DC input of 9.5 kWp, maximum AC output of 6 kW, peak efficiency of 97.6%, dimensions of 470x525x146 mm, a weight of 18.5 kg, an IP65 rating, natural convection cooling, and a standard five-year warranty. Monitoring is handled through the FusionSolar app, available on iOS and Android, and a web portal at eu5.fusionsolar.huawei.com.

The L1 model connects exclusively to Huawei's LUNA2000 battery via a proprietary DC bus and battery management system, meaning non-Huawei DC-coupled batteries cannot be used. LUNA2000 modules each have a capacity of 5 kWh and are stackable to 5, 10, or 15 kWh, with a usable capacity of 4.8 kWh per module, round-trip efficiency of 90%, and a ten-year warranty. Installed prices range from €1,800 to €2,200 per module.

Huawei's iStore controller allows automatic optimisation for dynamic electricity tariffs, configured through the FusionSolar app. With Irish overnight rates of 6-9 cents per kWh and peak rates of 35-50 cents per kWh, a 10 kWh battery can generate annual savings of approximately €300 to €440 through tariff arbitrage, the company says.
