Huawei LUNA2000-15KW-S0 battery, LifePo4, 15.0 kWh

This is the complete configuration of a Huawei battery stack for homes: one module that handles the electronics and three modules that contain the energy proper. Its role is to move the energy produced during the day into the interval when the house actually consumes, that is in the evening and at night. Each module works optimised separately, so the weakest module does not drag down the whole assembly. Installation and operation are automatic: after commissioning, the system decides by itself when to charge and when to discharge.

The 15 kWh can be used in full, at 100% depth of discharge, and the continuous power of 5 kW with a peak of 7 kW for 10 seconds covers the instantaneous consumption of a house, including motor starts. Indicatively, at an evening and night consumption of about 1 kW, the 15 kWh cover the interval from sunset until morning. The assembly is 1320 mm high and exceeds 160 kg, because the power module weighs 12 kg and each of the three battery modules 50 kg, so it needs an appropriate floor or plinth. The IP66 protection rating allows outdoor installation, and the noise below 29 dB makes it acceptable even in a technical room adjoining the living space.

Configuration: 1 x LUNA2000-5KW-C0 + 3 x LUNA2000-5-E0, LiFePO4 cells, 15 kWh usable at 100% DoD, 5 kW maximum output power, 7 kW peak 10 s, module-level optimisation. Nominal voltage 450 V in single-phase systems (350-560 V) and 600 V in three-phase ones (600-980 V); coupling on the DC side of Huawei SUN2000 inverters from the residential range, management through FusionSolar, several stacks in parallel through the CAN interface. Power module 670 x 150 x 240 mm / 12 kg, battery module 670 x 150 x 360 mm / 50 kg, total height 1320 mm, IP66, -20...+55 °C, noise below 29 dB. Declared certifications: CE, RCM, CEC.

Who it suits

Suitable for a house with high annual consumption, with a heat pump or an electric car, which wants to use almost all of its own photovoltaic production and has room for a stack of 1320 mm and over 160 kg.

Terms explained

• Battery stack: The modules are placed one above the other like identical boxes; you add modules to increase the capacity, without changing the rest of the installation.
• Module-level optimisation: Each module is managed separately, so a more worn one does not limit the energy available from the others.
• CAN interface: The communication channel through which several battery stacks coordinate with each other and with the inverter, so as to work as a single system.

Technical specifications

Recommended applications

• Homes with high annual consumption and maximised photovoltaic self-consumption
• Long-duration backup for the entire house, in combination with SmartGuard
• Houses with a heat pump and a charger for an electric vehicle
• Three-phase residential systems with Huawei SUN2000 inverters

Technical details

Specifications confirmed from the manufacturer's datasheet

LUNA2000-15-S0 is the maximum configuration of a Huawei Smart String Energy Storage stack: one LUNA2000-5KW-C0 power module and three LUNA2000-5-E0 battery modules, totalling 15 kWh of usable energy. The cells are LiFePO4, and the module-level optimisation allows the full use of the capacity, without the weakest module limiting the entire system.

The maximum output power is 5 kW, with a peak of 7 kW for 10 seconds. The nominal voltage is 450 V in single-phase systems (350-560 V) and 600 V in three-phase ones (600-980 V). The system is coupled on the DC side of Huawei SUN2000 inverters from the residential range and is managed through the FusionSolar platform; several stacks can work in parallel through the CAN interface.

The assembly is 1320 mm high; 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, so the complete assembly exceeds 160 kg and requires an appropriate supporting surface. The IP66 protection rating allows installation indoors or outdoors, the operating range is -20...+55 °C, and the noise in operation stays below 29 dB. Declared certifications: CE, RCM, CEC.
