The Huawei LUNA S1 energy storage system, initially available only with 7 kWh modules as an alternative to the LUNA S0 series, has now evolved to offer a new level of flexibility with the introduction of 5 kWh batteries.

A whole new range of configurations is now available thanks to the free combination of 5 kWh and 7 kWh modules, allowing up to 9 different total capacity levels for each BMS, from a minimum of 5 kWh up to a maximum of 21 kWh.

This innovative, reliable and safe energy storage solution is suitable for both residential and commercial applications. Compared with other storage systems, it stands out thanks to its Module+ architecture, which enables increased storage capacity and improves the total usable energy.

Key Features of the New LUNA S1 Batteries

LiFePO4 cells (Lithium Iron Phosphate – LFP)
Over 40% more total usable energy compared with conventional storage systems
Advanced safety ensured by a 5-level protection system
Fast and simplified installation thanks to the compact and modular design
Extendable warranty up to 15 years

These are the main distinguishing features of the new LUNA S1 range, delivering flexibility, optimisation, efficiency, simplicity and safety from the installer’s perspective.

Description

Over 40% usable energy

With the new Module+ architecture, the total usable energy is improved by more than 40%.

Silent operation <29 dB

The separate temperature control system and new insulation material, allow the cells and energy optimizers to work optimally and reliably while avoiding overheating or excessive cooling, thus eliminating the need for a fan and reducing noise to <29 dB.

Faster charging

Each battery module charges at 3.5 kW with a maximum input and output power of 10.5 kW.

Up to 15-year warranty

In laboratory tests, LFP Lithium-iron-phosphate batteries have passed rigorous tests that ensure reliability, safety, and quality.

High protection degree

Three-level protection: overcurrent, short-circuit at string and module level
IP66 degree of water protection
High resistance to impact and crushing: withstands up to 5T of pressure, can withstand sudden impacts
Active pressure release is an advanced emergency protection to reduce oxygen concentration and eliminate sources of combustion for fire prevention
Smart firefighting kit that detects and extinguishes fires in 15 seconds
