Huawei LUNA2000-10KW-S0 Battery, LifePo4, 10.0 kWh

The panels produce the most at midday, when the house is empty, and produce nothing in the evening, when everyone is at home. The battery covers exactly this gap: it collects the surplus from the middle of the day and gives it back when you need it. LUNA2000-10-S0 is a vertical assembly of modules which is mounted next to the inverter, indoors or outdoors, and works on its own, without your intervention. The cells are LiFePO4, a lithium chemistry used precisely for its thermal stability.

The 10 kWh can be used in full, at 100% depth of discharge, without a part permanently locked in the battery. The continuous power of 5 kW covers the instantaneous consumption of an average home, and the peak of 7 kW for 10 seconds takes on the starting of appliances with a motor, such as the heat pump or the washing machine. For a house with a consumption of 4-6 MWh a year, this capacity generally covers the evening and night part, which means that most of the energy produced stays in the house instead of being injected into the grid. The assembly is 960 mm high and exceeds 110 kg (12 kg for the power module plus two battery modules of 50 kg each), so it needs a solid supporting surface. It works below 29 dB, that is quieter than a fridge, and if the needs grow a third module is added, up to 15 kWh.

Configuration: 1 x LUNA2000-5KW-C0 (power module) + 2 x LUNA2000-5-E0 (battery modules), LiFePO4 cells, 10 kWh usable at 100% DoD, 5 kW maximum output power, 7 kW peak 10 s, smart string architecture with module-level optimisation. Nominal voltage 450 V in single-phase systems (range 350-560 V) and 600 V in three-phase ones (range 600-980 V); coupling on the DC side of the Huawei SUN2000 inverters, monitoring through FusionSolar. Power module 670 x 150 x 240 mm / 12 kg, battery module 670 x 150 x 360 mm / 50 kg, total height 960 mm, IP66 for indoors and outdoors, -20...+55 °C, noise below 29 dB. Declared certifications: CE, RCM, CEC.

Who it suits

Suitable for a house with a consumption of 4-6 MWh a year and a Huawei SUN2000 photovoltaic installation, which wants to cover its evening and night from its own production, with the possibility of expansion to 15 kWh.

Terms explained

• Usable kWh: The energy you can actually draw out of the battery; on this model it coincides with the total capacity, because discharge is allowed down to 100%.
• LiFePO4: A type of battery with lithium, iron and phosphate, chosen in home installations for its stable behaviour at temperature and for the large number of charges it withstands.
• The DC side of the inverter: The direct current side, the same one the panels are connected to; the battery is connected there, not to the household socket.

Technical specifications

Recommended applications

• Residential photovoltaic self-consumption with Huawei SUN2000 inverters
• Whole-house backup in combination with SmartGuard
• Covering evening and night consumption in houses with 4-6 MWh a year
• Systems later expandable to 15 kWh

Technical details

Specifications confirmed from the manufacturer's datasheet

LUNA2000-10-S0 is the 10 kWh configuration of the Huawei Smart String Energy Storage system, made up of a LUNA2000-5KW-C0 power module and two LUNA2000-5-E0 battery modules. The cells are LiFePO4, and the smart string architecture, with module-level optimisation, allows 100% of the stored energy to be used.

The maximum output power is 5 kW, with a peak of 7 kW for 10 seconds, which covers the instantaneous consumption of an average home including at the start-up of inductive loads. The nominal voltage is 450 V for single-phase systems (range 350-560 V) and 600 V for three-phase ones (range 600-980 V). The system is connected on the DC side of the Huawei SUN2000 inverters and is monitored through FusionSolar.

The total height of the assembly is 960 mm. The power module measures 670 x 150 x 240 mm and 12 kg, and each battery module 670 x 150 x 360 mm and 50 kg. The IP66 protection rating allows installation indoors or outdoors, the operating range is -20...+55 °C, and the noise level stays below 29 dB. The capacity can be increased to 15 kWh by adding a third module. Declared certifications: CE, RCM, CEC.
