Huawei Power Module LUNA2000-5KW-C0

Power Module / BMS - Huawei Power Module LUNA2000-5KW-C0

The Huawei LUNA2000-5KW-C0 is a compact DC/DC power module and battery management system (BMS) designed as the central control unit for the LUNA2000 modular high-voltage home energy storage platform. It orchestrates battery management, power monitoring and system communication for modular LFP battery strings, enabling scalable residential or small commercial storage from 5 kWh up to 30 kWh.

Applications and use cases

This power module is built for modular battery storage installations where flexible capacity, safe chemistry and inverter interoperability are required. It suits residential single-phase and three-phase systems as well as small commercial rooftops when paired with compatible inverters and 5 kWh battery modules.

• Modular home energy storage: expand in 5 kWh steps to meet changing consumption patterns.
• Backup and self-consumption optimisation: pack-level energy optimisation with full depth-of-discharge capability.
• Integration with hybrid and grid-tied systems via compatible inverters (SUN2000 series).
• Small commercial or multi‑phase installations when combined with appropriate inverter hardware.

Key electrical and performance parameters

The LUNA2000-5KW-C0 performs BMS, monitoring and DC/DC power conversion for high-voltage battery strings. It supports both single-phase and three-phase voltage topologies and communicates with multiple storage modules to manage system charging, discharging and balancing.

• Nominal voltage (single-phase systems): approximately 360 V with an operating range around 350–560 V.
• Nominal voltage (three-phase systems): nominal 600 V with an extended operating window approximately 600–980 V.
• System-level pack management: central BMS and power monitoring for modular LUNA2000 battery stacks.
• Designed to interface with SUN2000 inverter family (single- and three-phase models) for hybrid and PV-coupled operation.

Battery and backup capabilities

The device is part of a modular energy storage architecture based on lithium iron phosphate (LiFePO4 / LFP) cells that emphasizes usable energy and cycle stability. The architecture supports scalable capacity and configurable backup strategies at pack level.

• Modular battery design: 5 kWh battery modules that scale from 5 kWh up to 30 kWh in typical configurations.
• Pack-level energy optimisation allowing deep usage: manufacturer-stated 100% depth of discharge at pack level under designed control strategies.
• Lithium iron phosphate chemistry for long cycle life and thermal stability.
• System communication and coordination with multiple storage modules—module counts supported by controller communication for larger stacks.

Mechanical design and installation

The LUNA2000 power module is engineered for easy installation and quick commissioning. The unit is compact and lightweight relative to battery modules, simplifying mounting and site integration while battery modules remain the heavier components of the system.

• Compact power module mass: around 12 kg for the power/control module, enabling easier handling during install.
• Battery module mass reference: typical battery module ~50 kg (for sizing and mounting considerations).
• Installation options include freestanding base and wall‑mounting depending on site layout.
• Quick commissioning and system recognition: automatic detection by accompanying app for streamlined setup and commissioning.

Operating conditions, safety and compatibility

The LUNA2000-5KW-C0 implements standard safety and monitoring functionality expected from a modern BMS and meets multiple regional safety and performance standards. It was developed to integrate smoothly with Huawei inverter platforms and to provide robust protection and diagnostics for LiFePO4 battery stacks.

• Cell chemistry: Lithium Iron Phosphate (LFP) for improved thermal and chemical stability.
• Safety and standards: designed in line with industry certifications commonly applied to LUNA2000 components (CE, IEC and other regional approvals noted in technical documentation).
• BMS functions: cell balancing, over/under voltage protection, temperature monitoring and pack-level energy optimization.
• Compatibility: built to integrate with SUN2000 series inverters (selected single‑ and three‑phase SUN2000 models) and typical residential hybrid inverter workflows.
