Introduction

Thank you for choosing the Sunsynk SS-16kWh-F-BATT-IP21-00 Lithium Iron Phosphate (LiFePO4) battery. This energy storage system is designed for high-power applications, efficient use in limited installation spaces, and offers an exceptionally long cycle life. It provides safe and reliable power for residential, commercial, and industrial energy systems.

Each module delivers a 16 kWh capacity and can be connected in parallel with multiple units to expand the total system capacity and output power. This modular design makes the SS-16kWh-F-BATT-IP21-00 highly flexible, allowing system sizes to be scaled according to the energy requirements of the user.

The battery is equipped with a built-in Battery Management System (BMS) that:

  • Monitors real-time voltage, current, and temperature.
  • Ensures over-charge, over-discharge, over-current, and short-circuit protection.
  • Provides cell balancing to maximise performance and extend service life.
  • Communicates seamlessly with Sunsynk inverters and other approved compatible systems via CAN/RS485 and Bluetooth protocols.
