Battery storage (BESS) integration
Frax storage under smart control
Frax delivers an integrated storage system that combines the inverter, the battery management and the metering in a single managed unit. Voltmasters EMS turns it into an earning asset: market-driven charging and discharging, peak shaving and self-consumption optimisation.
Supported devices
- Frax EMS
The Frax EMS, with the inverter, the battery management, the PV and the metering in one unit. You enter the battery capacity during setup, it is not read from the device.
What the EMS gets out of your Frax installation
- Trade on the imbalance market and dynamic prices, quarter hour by quarter hour
- Peak shaving: keep peak power and capacity tariff under control
- Maximise self-consumption together with PV and EV chargers
- Fluvius telecontrol and grid compliance, certification included
- Real-time monitoring with automatic incident detection
Why installers combine Frax and Voltmasters
Frax delivers the complete package in one cabinet, Voltmasters adds the control. The EMS connects over Modbus TCP and shows the inverter, the battery management, the PV and the meter separately in the platform, so you follow up on each part. The Voltmaster Controller runs the optimisation locally, even without internet.

FAQ
Questions about the Frax integration
Which Frax system does Voltmasters support?
The integrated Frax EMS. It appears in the platform as an inverter with the battery management, the PV and the energy meter underneath it.
What can the EMS do with a Frax system?
Market-driven charging and discharging, peak shaving, self-consumption and grid compliance, controlled from a single platform.
Does the system keep working when the internet drops?
Yes. The Voltmaster Controller runs the optimisation locally in the cabinet. If the connection drops, control, peak shaving and the safety limits simply stay active.
How do I connect a Frax battery system to the EMS?
The Voltmaster Controller connects to the device over the local network. The step-by-step instructions are in our documentation, and as a certified partner we guide your first commissioning from start to finish.
