The NEWTRON Light storage ­system

NEWTRON Light is a comprehensive storage system that is suitable for container and building solutions. The battery system of the NEWTRON Light consists of lithium iron phosphate NEWTRON battery modules (NBM) that are certified in accordance with UN38.3/IEC 62281. In addition, NEWTRON Light has an independent inverter system that facilitates secure and efficient AC/DC conversion. The charge/discharge controller ensures a seamless interaction between the inverter(s) and battery system.

The storage ­system consists of

51.2NBM200 (battery module)

1. Battery system

Battery module

The NEWTRON battery module is a lithium iron phosphate battery (LiFePO4) with a rated DC voltage of 51.2 VDC and a rated capacity of 200 Ah. In addition, the NBM offers a 1C rate.

BMS (battery ­management­ system)

The battery management system (BMS) measures the state of charge (SOC) and state of health (SOH) of the battery system.

In addition, the BMS offers protection through targeted heat management of the battery module, and is equipped with an error diagnostic alarm that is displayed via an
information monitor.

  • Supervision of battery working conditions and monitoring
  • Determining the SoC / SoH
  • Monitoring charging and discharging functions
  • Thermal monitoring of the individual cells
  • Error monitoring and diagnostic monitor
  • Informational display
  • Monitoring equipment for safe operation of the
    battery storage system

Battery cabinet

The battery system is offered in a compact cabinet system perfectly tailored to the battery module, to offer safety while taking up the least possible space.


2. Inverter system

The inverter is a three-phase battery inverter for all kinds of storage applications. The inverter is certified in accordance with VDE-AR-N-4105:2018/VDE-AR-N-4110:2018.

Primary features

  • Integrated control card
  • Protective system
  • Surge protection
  • DC & AC circuit breaker
  • Insulation monitor
  • Current and voltage measurement
  • Internal data logger
  • DC precharging circuit
  • Grid stabilization
  • Provision of reactive power
  • Cooling system
  • Communication via Modbus TCP


  • Isolated mode
  • Touch display

3. CDC

The CDC is the control system that facilitates communication between the inverter system and battery management system. The CDC regulates safe charging and discharging of the battery system. The CDC also acts as an interface for an higher-level controller that uses Modbus TCP as the communication protocol. An operating interface also facilitates manual charging and discharging of the battery storage system.
