6.9 kWh usable high-voltage LFP battery module for Huawei LUNA2000 S1 energy storage.

Huawei LUNA2000-7-E1 is the larger E1 battery module for residential and smaller commercial photovoltaic systems. It stores 6.9 kWh of usable energy in a compact IP66 enclosure and uses lithium iron phosphate cell chemistry. One module forms the LUNA2000-7-S1 capacity step; two or three matching modules create the official 13.8 kWh and 20.7 kWh S1 configurations when the complete system is designed accordingly.

This item is not a complete battery system. The product supplied under this page is one LUNA2000-7-E1 battery module. A working installation also requires the compatible Huawei LUNA2000-10KW-C1 power and control module, a supported Huawei inverter, the specified mounting arrangement, protection, cabling and professional commissioning. These separately selected components are not included unless they are explicitly listed in the order.

Capacity steps of 6.9, 13.8 and 20.7 kWh

One to three 7-E1 modules can be installed in one S1 tower according to current Huawei design rules. Each module contributes 6.9 kWh of usable energy and up to 3.5 kW of charging or discharging power. A correctly configured two-module tower reaches 7 kW and a three-module tower up to 10.5 kW, subject to inverter capability, controller limits, firmware, temperature and the approved operating mode. Selected 5-E1 and 7-E1 combinations may also be possible only where current Huawei documentation explicitly permits the exact arrangement.

IP66 enclosure and quiet natural cooling

The module is intended for protected indoor or outdoor installation in accordance with Huawei mounting, clearance and environmental requirements. Natural convection avoids a continuously running fan and keeps the specified operating noise below 29 dB. The operating temperature range is -20 °C to +55 °C, although output may be reduced at temperature or altitude extremes. Floor mounting is standard; an approved wall-mounting arrangement is optional only where the supporting structure and manufacturer instructions allow it.

Key technical data

Compatibility is verified for the complete system

The module is intended for supported Huawei residential inverter families listed in current LUNA2000 S1 documentation. Compatibility depends on the full inverter suffix, phase arrangement, firmware, grid requirements, backup design and number and type of battery modules. A matching connector alone does not establish approval. WodaSign™ checks the complete component list and intended operating mode before confirming a system proposal.

Scope of supply

• 1 × Huawei LUNA2000-7-E1 battery module with 6.9 kWh usable energy.

The LUNA2000-10KW-C1 power and control module, inverter, backup equipment, meter, protection, installation material and labour are selected separately. Installation, electrical protection, earthing, cable sizing, firmware setup and commissioning must be completed by a qualified professional in accordance with current Huawei documentation and local regulations.
