Why Voltmasters
Dynamic prices, capacity tariffs, negative injection prices, telecontrol requirements: today's installation has to do far more than store electricity. Voltmasters EMS takes that complexity off your hands, and your customer's.
The algorithm plans ahead every 15 minutes based on day-ahead market prices, PV forecast and the consumption profile. Charge when it's cheap, discharge when it's expensive, including curtailment at negative prices.
Explore the platform →Through secure connections with trading partners such as Yuso, Trevion, BEE, Centrica and Elion, your customer's battery earns on the imbalance market, on top of the arbitrage savings.
More about energy trading →Six specialised dashboards, AI-driven health monitoring and automatic incident detection with alerts. You manage all your projects remotely; your customer watches along in their own environment.
Monitoring & incidents →How it works
The algorithm forecasts consumption, production and prices 24 hours ahead and turns that forecast into a day plan for the battery, chargers and grid. Every second the Voltmaster Controller checks that plan against reality and adjusts where needed.

The platform
From SME battery to industrial site with a charging plaza: the same controller, the same platform, the same workflow.
Automatic arbitrage on dynamic prices, validated against round-trip losses.
Read more →Dispatch signals from trading partners over MQTT or REST API, within the limits of the grid contract.
Read more →Distributes the available power dynamically across charge points, no grid reinforcement needed.
Read more →Real-time dashboards, automatic incident detection and a traceable digital logbook.
Read more →Telecontrol via IEC 60870-5-104 and quarter-hour values via the A1 port, certification included.
Read more →Monitors the quarter-hour power and adjusts battery and loads before the peak sets the bill.
Read more →The partner portal shows all your projects with live status, battery level, solar production and firmware version. You spot an incident on a site immediately, often before your customer calls.
Use cases
Case study 01 · Cras Ostend
A 250 kW / 500 kWh battery automatically covers the shortfall of the two Alpitronic fast chargers, and earns extra through balancing services on top.
Full charging power, no grid reinforcement.

Case study 02 · Negative prices
Eleven electric trucks, 8 battery containers and 420 kWp of PV: at negative prices the EMS flips the logic and the whole site charges from the grid at full capacity.
Charged, and paid for it.

Case study 03 · Battery Schedule
The Battery Schedule calculates the optimal charging plan per vehicle ahead of time, based on departure time, grid capacity and dynamic energy prices.
Every deadline met, at the lowest cost.
