An agreement with a deadline
By 7:00 tomorrow the car needs 100 km more in it.
Novolt turns those 100 km into kilowatt hours, picks the cheapest hours to charge them and moves them when prices change. The deadline stays put.
the car is ready on time
Belgian power market · 11 August 2026
At 14:00 almost free. At 19:45 30× the price.
Those prices were fixed the day before. Novolt tuned your battery, your car and your house to them.

Before you wake up, the day is already planned. Novolt steers your solar panels, your battery and your charger as one system, on tomorrow's prices and the rules that apply here.

What happens between the market price and your socket
Four layers. Each one does something you will never see, and each one is the reason the layer above it is allowed to be right.

Works with the hardware you already have
+ more brandsIt calculates by Belgian rules, not generic ones
A dynamic tariff is more than the exchange price. The rest of your bill counts just as much, and here it works differently than anywhere else.
Capacity tariff
Part of your bill does not depend on what you consume, but on your highest quarter-hourly peak. Novolt tracks your monthly peak and weighs it into every decision, including the 2.5 kW floor and the rolling year your tariff is calculated over.
Quarter hours, not hours
The Belgian market settles per quarter hour. Novolt plans on those same quarter hours, so a cheap half hour really is a cheap half hour.
Export that can cost you money
When there is plenty of sun, the payment for what you export drops to zero or below. Novolt checks every quarter hour whether exporting earns you anything, and keeps the power in the house otherwise.
Your grid area
Distribution costs differ per grid operator. Your tariff is set to the area where you live, not to a national average.
You say what has to happen, not how
No screen full of sliders. You set what has to happen or where the limit is, and the planner finds the cheapest way to keep to it.
A limit that always holds
My peak must not go above 5 kW.
Your monthly peak sets part of your bill, the capacity tariff. Novolt spreads the charging of your car and your battery so that they do not push you over it.
charging does not raise your peak
This is what it looks like. The app, with real figures.
Three screens do most of the work: what is flowing now, what Novolt plans and why, and what it earned you.
22:23 · one real moment
Power costs 38 cents right now. You are buying none of it.
The house runs on what the battery stored from the sun this afternoon. The grid is idle.

11 August · the plan for that day
Every decision comes with its reason.
What your battery and your car do, when, and why. In the plan beforehand, in the app afterwards.
10:00 → 17:00
Store solar surplus
Your panels are producing more than your house is asking for. The surplus goes to the battery instead of to the grid.
11:45 → 15:45
Charge battery from the grid
Cheap window, averaging 1,3 cents per kWh: the battery is topped up for the expensive evening.
11:45 → 15:45
Car charging scheduled
The cheapest hours that fit inside your commitment, so the car is ready on time.
19:15 → 23:15
Battery covers your usage
Expensive hours, averaging 18,1 cents per kWh: your own storage covers your usage instead of the grid.

Built in Belgium, close to the installation
Novolt is made by a small team that stands between the inverters and chargers themselves. The first installations are running today; with a handful of sites we're now building further.
You talk directly to the people who write the code. No helpdesk layer, no script. What your installation needs steers what we build.
Ghent, Belgium
inverter, meter and the box on the shelf
One device in your meter cupboard
The Novolt box goes next to your inverter and your meter, reads them and steers them. Your installation itself does not change.
- Nothing gets replaced
- Your inverter, your battery, your charger and your meter stay exactly what they are. Novolt talks to them, it does not take their place.
- One network cable
- The box hangs off your network. It needs nothing else.
- Keeps working locally
- The plan runs on the box itself, so your installation stays steered even if your internet drops for a while.
How to start. With one house, or a whole fleet.
One installation? You start right away. Several locations or a charging park? We put together a proposal.

Novolt is not an energy supplier: your contract and your installation stay yours.
Yes, that's what Novolt is built for. It sits on top of your installation and runs what's already there: inverter, battery, charger, meter. Give us the make and model and you'll know before you start whether it works. If an integration is missing, we build it.
Energy that runs itself. Tonight too.
Novolt steers your solar, your battery, your grid connection and your charger on a dynamic tariff, and shows you why it does what it does.
