Complete installation
Solar panels, inverter and battery installed by us, with inspection and registration with the grid operator included.
Solutions
We build the installation and the control layer on top of it. Which combination fits follows from what you want to achieve, and the order in which your devices get their turn decides the result.
What we build
Raise self-consumption
Use as much of your own solar energy as possible instead of exporting it at a low rate.
Lower the capacity tariff
Flatten your monthly peak by letting the battery step in and heavy devices give way to each other.
Direct solar surplus
Surplus goes in order to battery, hot water, climate and car rather than to the grid.
Backup on selected circuits
During an outage, pre-selected circuits keep running. Honest about what does and does not come along.
Dynamic tariffs
Consumption moves to cheap hours, with your comfort limits as the ceiling.
Improve an existing system
A second opinion on a battery that disappoints, and control logic on top of what is already there.
The capacity tariff, in plain language
Your grid operator measures every quarter of an hour how much power you draw from the grid. The highest quarter-hour average in a month is your monthly peak. The average of twelve monthly peaks, with a minimum of 2.5 kW per month, is what you are billed on.
For 2026 the Flemish regulator applies a reference rate of 53.39 euro per kW per year, excluding VAT. Per grid area the actual rate sits between roughly 49 and 57 euro. With 6 per cent VAT that comes to just over 56 euro per kW per year.
A household with an average monthly peak of 4.2 kW therefore pays around 240 euro a year in capacity tariff. Every kilowatt you take off that peak saves you just over 50 euro a year, every year.
One evening with the oven, the dryer and the car running together thus helps set what you pay for a year. Export does not count: only what you draw.
An EMS lowers that peak in two ways. It lets the battery step in at the moment the peak is forming, and it makes sure heavy devices do not start at once. How much that saves depends on your profile, which is why we would rather calculate on your quarter-hour data than on an example.
Rates are set annually. The figures above apply to 2026; ask us for the state of play at the moment you decide.
When we advise against it
With low consumption, no solar panels and no controllable devices there is little to control. A battery will not pay for itself, and we will say so.
Going fully off-grid is rarely the sensible choice for an ordinary home in Belgium. It is possible, but it needs a feasibility study and a far larger installation than people expect.
A backup that keeps your entire home running is something else than backup on a few circuits. What we promise is the second.
