HUAWEI 5KWH LITHIUM BATTERY

The Huawei 5kWh Lithium Battery represents Huawei’s commitment to delivering intelligent, reliable energy storage for residential solar installations. Engineered with advanced lithium-ion technology and seamless integration with Huawei’s solar inverter ecosystem, it provides homeowners with energy independence, backup power during outages, and significant electricity cost savings through smart energy management.

Advanced Lithium-Ion Technology

Built with high-quality lithium-ion cells, the Huawei 5kWh battery delivers over 10,000 charge/discharge cycles at 90% depth of discharge — significantly outperforming traditional lead-acid batteries and ensuring a service life exceeding 10 years under normal operating conditions. The high round-trip efficiency (>95%) minimizes energy loss during charging and discharging, maximizing the value of every kilowatt-hour stored.

High Depth of Discharge

With approximately 95% usable depth of discharge, the battery provides 4.75kWh of accessible energy from its 5kWh nominal capacity. This high DoD reduces the number of battery units needed for a given backup runtime, lowering upfront system costs while maintaining battery health and longevity.

Seamless Huawei Ecosystem Integration

Designed for plug-and-play integration with Huawei SUN2000 hybrid inverters, the battery automatically configures itself upon connection via Huawei’s proprietary communication protocol. Real-time monitoring, charge/discharge control, and system diagnostics are accessible through the Huawei FusionSolar mobile app and web portal, providing homeowners with complete visibility into their energy storage system.

Intelligent Battery Management

The integrated BMS continuously monitors cell voltage, current, and temperature, providing multi-layer protection against overcharge, over-discharge, short circuits, and thermal events. Active cell balancing ensures even wear across all cells, extending overall battery pack lifespan and maintaining consistent performance over time.

Compact, Quiet, and Safe

The compact modular design enables flexible installation in space-constrained utility rooms, garages, or outdoor enclosures (with appropriate weather protection). Fanless operation ensures silent performance, while lithium-ion chemistry provides inherent safety advantages over alternative battery technologies when properly managed by the BMS.

Modular Expansion

Start with a single 5kWh module and expand capacity as energy demands grow by adding additional battery units in parallel — providing a scalable solution that grows with your household’s needs.

A proven energy storage solution from a global technology leader, delivering reliability, performance, and peace of mind for residential solar systems.
