Battery Huawei LUNA2000-5-E0 LiFePO4 5 kWh (BMS)

The battery solves the gap between the moment the panels produce and the moment the house consumes: at midday it fills up, in the evening it empties. This product is a 5 kWh module, that is one brick of the Huawei LUNA2000 system, and if more energy is needed several modules are stacked. The cells are LiFePO4, a lithium chemistry chosen for stability and long service life.

The 5 kWh are fully available, at 100% depth of discharge, so the figure on the label is the energy you really use, not a theoretical one. The output power is 2,5 kW per module, with a peak of 3,5 kW for 10 seconds, which means that a single module covers the base consumption of a house, while for large loads further modules are added. Up to 3 modules are stacked on a tower, and two towers can be connected in parallel, so the system can reach 30 kWh. The module measures 670 x 150 x 360 mm and weighs about 50 kg, so it needs a solid wall or platform; the IP66 enclosure allows outdoor mounting, the battery status is followed in the FusionSolar app, and the warranty is 10 years.

LiFePO4 cells, 5 kWh usable at 100% DOD, module rated voltage 360 V, maximum output power 2,5 kW with a peak of 3,5 kW for 10 s. The voltage range at system level is 350-560 V in single-phase configurations and 600-980 V in three-phase configurations, depending on the coupled SUN2000 inverter. The module is combined with the LUNA2000-5KW-C0 power and control unit, of about 12 kg, to form the LUNA2000-5-S0, -10-S0 or -15-S0 systems; a maximum of 3 modules per tower and 2 towers in parallel, up to 30 kWh. Dimensions 670 x 150 x 360 mm, mass about 50 kg, IP66, BMS included with pack-level monitoring in FusionSolar.

Who it suits

Suitable for a house with a Huawei SUN2000 inverter, single or three-phase, that wants to start from 5 kWh and expand the capacity later, including with the battery mounted outdoors.

Terms explained

• DOD (depth of discharge): How much of the battery capacity you can actually use; 100% DOD means that all 5 kWh are available.
• Power and control module (LUNA2000-5KW-C0): The separate part that manages the charging and discharging of the battery tower; without it, the energy modules do not work on their own.
• IP66: An enclosure completely protected from dust and resistant to powerful water jets, so the battery can be mounted outdoors.

Technical details

Specifications confirmed from the manufacturer's datasheet

Huawei LUNA2000-5-E0 is the 5 kWh battery module of the Smart String ESS LUNA2000 system. The cells are LiFePO4, and the Huawei architecture with module-level optimisation allows 100% of the rated energy to be used, so 5 kWh available. The rated voltage of the module is 360 V.

The maximum output power per module is 2,5 kW, with a peak of 3,5 kW for 10 seconds. At system level, the working voltage range is 350 - 560 V in single-phase configurations and 600 - 980 V in three-phase configurations, depending on the SUN2000 inverter it is coupled with.

The module is combined with the LUNA2000-5KW-C0 power and control module, which weighs approximately 12 kg, to form the LUNA2000-5-S0, -10-S0 or -15-S0 systems. Up to 3 modules can be stacked on a tower, and two towers can be connected in parallel, reaching 30 kWh.

The enclosure has IP66 protection rating, which allows outdoor installation. The dimensions of the module are 670 x 150 x 360 mm, with a mass of approximately 50 kg. The battery management system is included, with pack-level monitoring in the FusionSolar app.
