Strategic partner of Poweroad

Voltmasters and Poweroad signed a strategic partnership MoU to jointly advance the deployment of BESS storage solutions. We align the control and the battery perfectly: not a connection bolted on afterwards, but an integrated whole that we keep improving together. That is why Voltmasters is the control of choice for Poweroad batteries.

Our controller in the Poweroad factory

A Voltmaster Controller is permanently installed at Poweroad. That lets us develop and test the control for every new product and firmware release before it reaches the market.

Control and hardware tuned to each other

Because we work directly with the Poweroad team, we get the most out of every FLEX battery: faster commissioning, more reliable control and support for new models from day one.

The control of choice for Poweroad

Voltmasters is the standard EMS for the FLEX series. One whole of robust hardware and smart control, with a revenue model ready to go.

What the EMS gets out of your Poweroad 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 Poweroad and Voltmasters

Poweroad delivers robust all-in-one battery cabinets, Voltmasters delivers the intelligence. The EMS supports both PMS version 1 and version 2 and works with air-cooled and liquid-cooled variants. The Voltmaster Controller steers the battery locally, so the optimisation keeps running when the internet connection drops.

How your Poweroad 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.

Questions about the Poweroad integration

Are Voltmasters and Poweroad partners?

Yes. Voltmasters and Poweroad are strategic partners. We develop and test the control on a Voltmaster Controller that is permanently installed at the Poweroad factory, so the control of every FLEX battery and every new firmware release is right from day one.

Which Poweroad systems does Voltmasters support?

The full FLEX series: FLEX 126 AIO, FLEX 215, FLEX 215 AIO, FLEX 215 AIOS and FLEX 233 AIO. We support both PMS version 1 and version 2, in air-cooled and liquid-cooled versions.

Can I trade on the imbalance market with a Poweroad battery?

Yes. The EMS automatically reads the market prices and plans charging and discharging quarter hour by quarter hour. At a transport company in West Flanders this yielded up to −€200.83/MWh during negative prices.

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 Poweroad battery 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.
