Huawei LUNA S1 – 7/14/21 kWh: in-depth review

In this article, we will delve into the new Huawei LUNA S1 energy storage system, designed to provide maximum flexibility and optimization, allowing the user to adapt the energy capacity to their specific needs thanks to its modular plug & play system.

The optimization of each battery module is achieved through the use of advanced technologies that ensure efficient energy management, improving battery life, operational efficiency, and safety.

Below are the technical specifications and a video showcasing the easy installation of this Huawei product.

Technical Specifications

The Huawei LUNA S1 batteries stand out for a series of advanced technical features:

  • Technology: LiFePO4 (Lithium Iron Phosphate), which offers greater safety and long lifespan.
  • Operating Range: from -20°C to +50°C
  • Installation Environment: suitable for both outdoor and indoor installations
  • Cooling: air cooling system through natural convection, avoiding the use of fans and reducing maintenance
  • Dimensions and Weight:
    • Width: 590 mm
    • Depth: 255 mm
    • Height: variable (510 mm for one module, 870 mm for two modules, 1230 mm for three modules)
    • Weight: Power Module 10 kg, Battery Module 68 kg
  • Noise Level: below 29 dB
  • Protection Rating: IP66
  • Submersion Functionality: capable of operating submerged up to 40 cm for 72 hours
  • Explosion-proof Valve: present in each module to ensure maximum safety

Simplified Installation

The installation of Huawei LUNA S1 batteries has been significantly simplified to ease technicians’ work and reduce setup times.

One of the key aspects is the assisted transportation, made possible by the removable handles that allow easy handling of the battery modules.

Additionally, the quick-connect system without the need for wiring enables immediate and secure connection between the various system components. This innovative connection method eliminates the complexity of traditional wiring, reducing the risk of errors during installation and ensuring greater system reliability.

In the installation video available here, the simplicity of the process is shown, highlighting how the batteries can be quickly assembled and ready for use in a few simple steps.

The connection between the various modules is ensured by the quick-connect plug, further simplifying the installation process.

It is also important to note that:

  • the wiring for the S1 model must be done from the left side of the Power Module
  • S0 and S1 models cannot coexist in the same system
