Get more out of every energy installation

The Voltmasters EMS stacks six revenue streams on the same batteries, solar panels and chargers. One self-learning algorithm decides every second what pays off most: self-consumption, dynamic tariffs, energy trading, peak shaving, grid services and higher uptime, fully automatic.

Six revenue streams

One coordinated strategy instead of a single revenue stream, without extra complexity for the installer or end customer.

One product, three components

The Voltmasters EMS is one whole: the Voltmaster Controller runs the smart steering locally in the installation, while the web platform and mobile app handle configuration and reporting. The intelligence lives in the installation itself, not in the cloud, and together they steer batteries, solar panels, chargers and consumers in every energy application, wherever you are.

The Voltmaster Controller, an industrial edge controller on a DIN rail

01 · The controller

The heart of the installation

An industrial edge controller on a DIN rail running the smart steering. A decision every second for every device, and during an internet outage the installation simply keeps running locally.

A self-learning brain that decides every second

The algorithm processes millions of data points per hour and determines the best strategy for charging, discharging, injection and consumption in real time. It learns from the installation, the market and the grid, automatically avoiding penalties, congestion and negative prices.

AI forecasts 24 hours ahead

Expected consumption, production and energy flows based on historical data, market prices, weather and solar irradiance. On sudden changes the system recalculates immediately.

A decision every second for every device

Taking each device's response speed into account, with a reaction time of 1 to 3 seconds.

Fully autonomous, 24/7

Arbitrage, peak shaving and grid services without any manual input or configuration.

Control strategies

Cost optimisation

The primary algorithm minimises energy costs using dynamic prices: charge when it's cheap, discharge when it's expensive. It plans per quarter-hour using day-ahead market prices (EPEX), weather-based PV forecasting and the consumption profile, and only cycles when the price spread justifies the round-trip losses (typically ± €20/MWh, configurable per project).

Self-supply

Maximises self-consumption of solar power. Runs fully local and reactive: PV surplus is stored and used later, minimising grid exchange. Ideal for customers on a classic contract or with a wide injection-consumption spread.

Imbalance trading

External trading partners send dispatch signals that steer the battery on the imbalance market. Those signals take priority over the standard algorithms but always stay within project limits and safety margins. More about energy trading →

All features

BESS optimisation

Automatic arbitrage on dynamic prices. The battery schedule sets the optimal charge and discharge moments per quarter-hour and is updated continuously.

Peak shaving & capacity tariff

Monitors the quarter-hour power and adjusts battery and loads before the peak drives up the capacity tariff.

PV curtailment

Automatically curtails inverters at negative injection prices. No more paying to produce on sunny Sundays.

Forecasting

Weather-based PV forecasting and consumption prediction feed the optimisation. Measured production versus forecast is visible in the PV dashboard.

Consumption planning

Enter planned large loads in advance; the system pre-charges the battery for known peaks.

Load management

Automatically sheds low-priority consumers when thresholds are exceeded, with configurable hysteresis for stable behaviour.

Manual overrides

Temporarily set the battery power yourself or disable algorithmic control for a chosen time window.

Grid protection

Import and export limits from the grid contract are strictly enforced, with a safety margin below the contractual limits.

Multi-site & roles

All your projects in one portal. Role-based access: you configure as the installer, your customer watches along with read access.

The controller steers, the platform lets you watch

Power follows the grid, the control signals come from the controller. Everything that happens locally, you see live in the platform and the app.

THE BRAIN Solar PV Grid Battery EV chargers Consumers energy flow control signals
Power follows the grid. The brain of the site, the Voltmaster Controller, steers every device, every single second.

Works with the hardware you already know

The EMS is brand-independent: 50+ brands and models of batteries, inverters, energy meters and chargers, steered over Modbus TCP/IP. You pick the hardware that fits the project; the EMS steers them all.
