Device integrations

Frax

The Frax EMS battery system in the Voltmasters EMS: one Modbus TCP unit exposed as a PCS with its own BMS and on-board metering.

Our EMS supports battery systems from Frax.

Frax supplies an integrated energy storage system that combines the power conversion system (PCS), battery management system (BMS) and on-board metering in a single managed unit.

Supported devices

  • Frax EMS: integrated battery energy storage system

The Frax system connects over Modbus TCP and is represented as a battery inverter (PCS) together with its battery management system, on-board PV and an energy meter. The battery capacity is entered during device setup: it is not read from the device, so make sure it is configured correctly.

The Frax integration does not expose cumulative energy counters, so production and consumption totals are derived from live power measurements.

EMS functionality

With the current integration, our EMS enables:

  • Monitoring of battery status and performance
  • Smart charging and discharging control
  • Optimization of self-consumption
  • Peak shaving and load balancing

Additional functionality may be added over time as integration capabilities evolve.
