    Huawei LUNA2000 S1 5 kWh Battery Module

    For reviewed Huawei LUNA2000-S1 architectures. Exact model and firmware compatibility apply.

    Exact reference · LUNA2000-5-E1

    A 5 kWh LiFePO4 module for Huawei LUNA2000-S1 storage. It requires the separate C1 power module and a compatible Huawei inverter.

    Product role
    S1 LiFePO4 battery module

    The battery cells are here; the controller and inverter are separate.

    Usable capacity
    5 kWh per 5-E1 module

    5 kWh is the beginning-of-life usable value under Huawei test conditions; actual delivered energy depends on operation.

    Stack composition
    1 C1 + 1–3 E1 modules
    Maximum stack charge/discharge
    3.5 / 7 / 10.5 kW

    Values correspond to one, two or three modules. The inverter and operating conditions may impose lower limits.

    Voltage architecture
    350–560 V single phase · 600–980 V three phase

    These are system operating ranges, not a universal fixed battery voltage.

    Choose the complete system from the load profile, usable capacity, required power and supported inverter configuration.

    What this product does in the system.

    A 5 kWh LiFePO4 module for Huawei LUNA2000-S1 storage. It requires the separate C1 power module and a compatible Huawei inverter.

    Relevant applications

    • Compatible Huawei residential solar and storage systems
    • S1 stacks with 5, 10 or 15 kWh using 5-E1 modules

    Why ReneWave may shortlist it

    • One to three 5-E1 modules provide 5, 10 or 15 kWh.
    • Maximum stack charge/discharge power grows from 3.5 to 7 to 10.5 kW.
    • S1 stacking connectors avoid inter-module power cables.

    Built-in capabilities

    Four functions, read before the headline specifications.

    Stores 5 kWh per module

    One to three 5-E1 modules form a 5, 10 or 15 kWh stack.

    Capacity and available output depend on the installed battery-module count.

    Module count changes output

    Maximum charge/discharge power is 3.5, 7 or 10.5 kW per stack.

    These are manufacturer maxima, subject to inverter limits and operating conditions.

    Commissioned through FusionSolar

    The supported inverter and ESS configuration provide system status and settings.

    5-E1 requires the supported ESS software and inverter firmware.

    IP66 enclosure and natural cooling

    The enclosure is rated IP66 and uses natural convection.

    Mounting clearances and temperature derating still apply; the rating does not remove installation requirements.

    System position

    Where the E1 stores energy.

    A compatible Huawei inverter connects to the C1 controller, which coordinates the E1 battery modules. PV and AC loads do not connect directly to the battery.

    Solar supplies the site through the inverter; the S1 battery is idle.

    Solar power passes through the compatible inverter. The inverter battery interface connects through the C1 controller to the E1 modules. Battery support returns through the controller and inverter. Grid charging depends on the approved settings. In the separate SmartGuard backup configuration, the grid is isolated and only the protected backup circuits receive inverter AC power. The C1 and E1 have no standalone AC output.

    03 · Confirm before quotation

    Four checks before this reference is quoted.

    ReneWave confirms the electrical context, connected equipment, installation conditions and configuration path before the exact reference enters a written quote.

    1. 01

      Confirm the complete S1 configuration

      Verify inverter firmware, module count, mounting and commissioning. S0 and S1 components cannot be substituted.

    2. 02

      Match capacity and power to the load

      Check the usable capacity and inverter limits together. A single 5-E1 module is not a 10.5 kW battery stack.

    3. 03

      Confirm the installation conditions

      Check structural support, safe handling, clearances, protection and ambient temperature. Each E1 module weighs 68 kg.

    4. 04

      Confirm firmware and handover records

      Use the supported ESS and inverter versions, then confirm the serials, warranty terms and supplied package.

    04 · Documents & warranty

    Keep the exact reference traceable.

    Documents shown here support selection and handover. The accepted order and exact manufacturer warranty document control.

    Manufacturer warranty reference

    10-year manufacturer product warranty under the current residential ESS policy. Years 6–10 require FusionSolar connection; the supplied contract and serialized product record govern coverage.
