The SolaX X1-FIT G4 3.7kW AC Inverter and 5.8-17.3kWh SolaX T58 5.8kWh Battery Energy Storage System (5.8-17.3kWh/3.7kW AC Coupled ESS) comprises:

This 5.8-17.3kWh/5.0kW AC Coupled ESS efficiently manages energy usage, ensuring a stable electricity supply and reducing costs by charging the battery with solar or low-priced off-peak Octopus electricity. Coupled with a private power source like on-grid solar panels, it provides a continuous 24/7 power supply for your home.

The 5.0kW X1-FIT G4 AC Coupled Battery Inverter is designed for compatibility with an external backup generator, seamlessly supplying electricity during prolonged grid outages when the battery storage is emptied.

    • SolaX 5.8kWh Triple Power T58 Master ans Slave Battery Module: A high-performance, scalable battery storage module with a modular design for maximum flexibility. Easy installation, plug-and-play solution, 95% charge/discharge efficiency, 100% depth of discharge, and a cycle life of over 6000 cycles.
    • SolaX X1-FIT G4 3.7kW AC Coupled Battery Inverter: A high-quality inverter converting solar energy to AC energy, compatible with high voltage batteries. Suitable for indoor or outdoor installation, featuring natural cooling, quiet operation, and low maintenance.
    • SolaX X1-FIT G4 3.7kW AC Battery Inverter Working Modes:
      • Self-use (default): Because there is no PV supplied, battery will discharge for local loads firstly, and grid will supply power when the battery capacity is not enough.
      • Feed in priority: The priority of inverter output power is: feeding to the grid  --> supplying the load --> charging the battery. This work mode applies to the area with high feed-in tariff.
      • Force time use: In this work mode the charging and discharging time can be set flexibly, and 
      • Back up mode: Battery will stop discharing to keep higher capacity when the grid is on. Only when the gird is off is not enough, battery will start to discharge to keep the emergency load working normally. This work mode applies to the area where suffering from blackout regularly.

    The system seamlessly integrates with smart Octopus tariffs, allowing automatic optimization for Plunge Prices and super cheap prices. With solar panels and the battery storage system, your electric unit price can be drastically reduced!
