Manufacturer: Sunwoda

INDEX: ATRIX15LV

Product number: ATRIX15LV
Product information "Energy storage set Atrix 15 kWh Sunwater"

Sunwoda Atrix energy storage systems can be used to support back-up power for various types of equipment and systems. Atrix batteries allow up to 100% DoD discharge, and a system built on them can operate without issues at temperatures below 0°C. They are especially recommended where a demanding operating environment is one of the selection criteria for energy storage systems. The IP20 protection rating against moisture requires indoor installation. Atrix batteries can be installed as free-standing towers or mounted in rack-type cabinets. They are ideal for limited installation space with restricted load-bearing capacity while requiring long service life.


The Atrix 5 kWh lithium-ion battery is the basic building block of Sunwoda energy storage systems. This low-voltage battery is used to build demanding energy banks with capacities from 5 up to 120 kWh. At maximum capacity, the set consists of 6 towers with 4 batteries in each, all connected in parallel. An energy storage system built in this way can work with inverters from various well-known brands, communicating via the RS485 port. 

Atrix 5 kWh is a battery with a nominal voltage of 51.2 V built in LFP technology with a usable capacity of 5 kWh and a charge/discharge power of 2.5 kW, featuring an integrated BMS for cell management and monitoring of voltages, currents and temperature. Moreover, the BMS directly influences the balancing of cell charge/discharge states to extend cycle life.

Key features of the Sunwoda Atrix battery module:

  • Battery based on LFP technology, nominal voltage 51.2 V
  • Charge and discharge power – 2.5 kW
  • Battery Management System (BMS) with protection against overcharge, overloading, overcurrent and high/low temperature
  • The system can automatically manage charge/discharge status and balance the current and voltage of each cell
  • Compatible with inverters from various brands
  • Easy expansion: up to 4 batteries per tower and up to 6 sets in parallel, from 5 to 120 kWh
  • Up to 100% DoD discharge
  • Operating temperature range: -10°C to 50°C (charging -10~50°C; discharging -20~50°C) with high efficiency
  • Designed for convenient installation and maintenance
  • Low failure rate
