When it may not be suitable

This unit is specifically designed as a master module for the Solax stackable system and may not be compatible with third-party inverter brands or non-modular battery architectures. It is not intended for mobile applications such as marine or automotive use where vibration and mounting requirements differ significantly from stationary residential installations.

Key specifications

• Battery chemistry: Lithium Iron Phosphate (LFP)
• Capacity: 5.8 kWh
• Depth of Discharge (DoD): 95%
• Cycle life: Over 6000 cycles
• Ingress protection: IP66
• Operating temperature range: -30°C to 55°C

How to use

The Solax 5.8kWh Master module should be installed by a certified professional in accordance with the manufacturer's guidelines. The unit is designed to be stacked vertically, allowing for easy integration with additional slave modules to increase total system capacity. Ensure the installation site is level and provides adequate clearance for ventilation. Once physically mounted, the module must be connected to the compatible Solax inverter and configured via the system interface to ensure proper communication and charging parameters.

What to consider before purchase

• Compatibility with your existing inverter system
• Total energy storage requirements for your household or business
• Available physical space for a stackable battery tower
• Local electrical regulations and installation requirements

Usage recommendations: To maximize the lifespan of your battery system, ensure it is installed in a location protected from direct, prolonged sunlight and extreme moisture. Regularly monitor the system performance through the dedicated monitoring application to ensure optimal operation and to receive timely firmware updates.
