Battery storage (BESS) integration
RCT Power CESS, large-scale storage smartly controlled
RCT Power builds commercial energy storage systems (CESS) that combine battery and power conversion, distributed in the Benelux by EcoPowerCell. Voltmasters EMS turns it into an earning asset: market-driven charging and discharging, peak shaving and grid-balancing services.
Supported devices
- CESS 1044-500-01D
- CESS 783-375-01D
The CESS 1044-500-01D (1044 kWh / 500 kW) and the CESS 783-375-01D (783 kWh / 375 kW), distributed in the Benelux by EcoPowerCell. Supported from controller version 0.0.268.
What the EMS gets out of your RCT Power 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 RCT Power and Voltmasters
The CESS series brings ample capacity to commercial and industrial sites and needs tight control to deliver its return. Voltmasters aligns the battery with the market, the PV and the consumption and guards the grid connection. The Voltmaster Controller runs the optimisation locally, even without internet.

How your RCT Power connects to the EMS
Voltmaster Controller in the cabinet
The industrial DIN-rail controller sits next to the installation and runs the optimisation locally, even without internet.
Connect over the local network
You connect the device following the step-by-step guide in our documentation. We assist with commissioning on your first project.
Configure and go live
The installation appears in the platform: dashboards, control and monitoring are active right away.
FAQ
Questions about the RCT Power integration
Which RCT Power systems does Voltmasters support?
The CESS 1044-500-01D (1044 kWh / 500 kW) and the CESS 783-375-01D (783 kWh / 375 kW), distributed in the Benelux by EcoPowerCell.
What can the EMS do with an RCT Power CESS?
Market-driven charging and discharging, peak shaving, grid balancing and self-consumption optimisation, 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 RCT Power CESS 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.
