Huawei LUNA2000-5-E1 5kWh LiFePO4 Storage Battery

The Huawei LUNA2000-5-E1 is the new-generation lithium battery module of the LUNA2000 family, designed for photovoltaic energy storage in residential and commercial applications. With a usable capacity of 5 kWh and 100% DoD, it maximises self-consumption of the energy produced by the PV system, drastically reducing grid imports.

E1 generation: what changes versus E0

The -E1 version is the most recent revision of the 5 kWh LUNA2000 series and brings substantial improvements over the previous -E0:

• Compatibility with LUNA2000-7-E1 7 kWh battery modules — flexible 5+7 kWh combination under a single BMS
• Module+ architecture with an integrated energy optimiser for each module
• Extended operating temperature: from -20°C to +55°C
• Improved IP protection for installation in more exposed environments

Note: the LUNA2000-5-E1 is not backward compatible with the LUNA2000-5-E0 series.

Module+ architecture — independent optimisation for each module

Each LUNA2000-5-E1 battery module integrates its own energy optimiser that manages it independently of the other modules in the same tower. This brings concrete advantages:

• Expansion without losses — you can add new modules to already-used ones without penalising overall performance
• More recoverable energy — usable energy can increase by more than 10% over the life cycle compared with systems without optimisation
• Fast charging — 3.5 kW per single module, up to 10.5 kW per group (3 modules)

5-level safety

The LUNA2000-5-E1 protection system operates on five distinct levels:

• Cell level — inherently stable LiFePO4 chemistry, without the thermal runaway risk typical of NMC
• Electrical level — protection against overcurrent and short circuit at string and module level
• Structural level — separate compartments for cells and optimisers with thermal insulation
• Active protection — 4 temperature sensors every 8 cells, continuous 24/7 monitoring with pre-alarm
• Emergency protection — active pressure-release technology to reduce oxygen concentration and prevent fires

Silent operation and smart management

The fan-less thermal management system ensures a noise level of just 29 dB — equivalent to a whisper — making the battery suitable for installation even in living areas. Through the Huawei FusionSolar app you can monitor energy flows, state of charge and yields in real time and set custom operating modes (TOU, maximum self-consumption, grid feed-in).

Inverter compatibility

The LUNA2000-5-E1 is compatible with Huawei SUN2000 series inverters, in particular:

• SUN2000 L1 series (single-phase residential)
• SUN2000 M0 and M1 series (three-phase residential and commercial)
• SUN2000 MB0 series — supports up to 4 groups in parallel for maximum system capacity

Operating voltage: 350–560 V (single-phase systems) — 600–980 V (three-phase systems).
