Features
High-Capacity 20.7 kWh Energy Storage
The Huawei LUNA2000-21-S1 provides 20.7 kWh of usable battery capacity, making it an ideal energy storage solution for medium to large residential homes and light commercial applications. It efficiently stores excess solar energy generated during the day for use at night, during peak electricity pricing, or in the event of a grid outage when paired with a compatible backup solution.
Intelligent Smart String ESS Architecture
Huawei’s Smart String Energy Storage System architecture enables intelligent energy management at the module level, improving system efficiency, operational reliability, and long-term performance. The modular design also simplifies installation, maintenance, and future expansion.
Safe Lithium Iron Phosphate (LiFePO₄) Battery Technology
The system utilizes premium Lithium Iron Phosphate (LiFePO₄) battery cells, offering excellent thermal stability, enhanced operational safety, long service life, and outstanding cycling performance. LiFePO₄ chemistry is recognized as one of the safest battery technologies available for residential energy storage.
Powerful 10.5 kW Charge and Discharge Capability
With a maximum charging and discharging power of 10.5 kW, the LUNA2000-21-S1 delivers sufficient power to support high household energy demands while maximizing solar self-consumption and reducing dependence on the utility grid.
Intelligent Battery Management System (BMS)
Huawei’s advanced Battery Management System continuously monitors voltage, current, temperature, and overall battery health. Intelligent cell balancing and multi-level protection help maximize battery lifespan while ensuring safe and reliable operation.
Modular and Scalable Design
The LUNA2000-21-S1 consists of one power control module and three battery modules. The modular design simplifies transportation, installation, servicing, and future capacity expansion. Up to four battery systems can be connected in parallel, depending on the supported system configuration.
Seamless FusionSolar Integration
The battery integrates seamlessly with Huawei FusionSolar, allowing homeowners and installers to monitor solar production, battery status, energy consumption, and system performance in real time through a smartphone app or web portal.
Silent Natural Cooling
Unlike conventional battery systems that rely on active fan cooling, the LUNA2000-21-S1 uses passive natural convection cooling, resulting in extremely quiet operation with noise levels below 29 dB while reducing maintenance requirements.
IP66 Weather Protection
Designed for both indoor and outdoor installations, the enclosure features an IP66 protection rating, providing excellent resistance against dust, rain, and harsh environmental conditions.
Smart Backup Power Support
When combined with compatible Huawei SUN2000 Hybrid Inverters and Huawei SmartGuard, the system can provide reliable backup power for essential household loads during utility outages.
