Utilizing advanced Lithium Iron Phosphate (LFP) technology, the battery provides a stable and safe power supply, ensuring that excess energy generated during the day is efficiently stored for later use.

Advantages

This battery module stands out due to its impressive 95% depth of discharge, which allows for maximum utilization of the stored energy without compromising the health of the battery. The robust construction supports a lifespan exceeding 6000 cycles, offering long-term reliability for your energy infrastructure. Furthermore, the unit is designed to operate effectively in a wide temperature range from -30°C to 55°C, making it suitable for diverse environmental conditions. With an IP66 protection rating, the module is well-protected against dust and water ingress, ensuring durability in various installation settings.

Suitable for

  • Residential solar energy storage systems
  • Commercial solar power installations
  • Off-grid and hybrid energy setups
  • Scalable energy capacity expansion

This slave unit may not be suitable for standalone operation as it requires a compatible master unit to function within a battery system. It is also not intended for use in environments that exceed the specified temperature limits or in applications requiring different battery chemistry types.

Key specifications

  • Capacity: 5.8kWh
  • Battery Type: Lithium Iron Phosphate (LFP)
  • Depth of Discharge: 95%
  • Cycle Life: Over 6000 cycles
  • Operating Temperature: -30°C to 55°C

How to use

The Solax battery module is designed for professional installation within a compatible Solax energy storage system. The modular design allows for easy stacking with other units to increase total system capacity. Installation should be performed by a qualified technician to ensure all electrical connections are secure and the system is properly configured with the master control unit. Once installed, the system integrates with the solar inverter to manage charging and discharging cycles automatically based on energy production and consumption patterns.

What to consider before purchase

  • Ensure compatibility with your existing Solax master battery unit
  • Verify that the installation location meets the IP66 environmental requirements
  • Confirm that your inverter supports the total capacity of the stacked battery system
  • Check local regulations regarding the installation of lithium-based energy storage systems

Usage recommendations

For optimal performance and longevity, ensure the battery is installed in a well-ventilated area away from direct heat sources. Regularly monitor the system via the connected inverter interface to track performance and ensure firmware remains up to date.
