Description

Innovative storage solution for your home

The HUAWEI LUNA2000-21-S1 offers a modular and powerful storage solution with a usable capacity of 20.7 kWh (with three 6.9 kWh modules). Expandable up to 82.8 kWh by combining multiple systems in parallel – ideal for demanding residential storage solutions.

Easy installation and operation

Commissioning is straightforward via plug-and-play using the FusionSolar app. The system is compatible with HUAWEI SUN2000 inverters of the L1, M1, and MB0 series and enables optional backup power functions via the Huawei Backup Box. Status indicators via LED and SOC display provide information about the operating status at all times.

Maximum safety and reliability

The robust lithium iron phosphate cells (LiFePO₄) allow 100% deep discharge. The 5-layer security concept protects against overcharging, overcurrent, overtemperature, and short circuits at the module, cell, and system level. With IP66 protection, underwater resistance (up to 40 cm for 72 hours), and passive cooling, the system is extremely reliable and low-noise (<29 dB).
