Short answer
By having your installation controlled. Electricity you do not use yourself, you sell for a fraction of what you will later pay to get it back. That is why the energy-management software decides, every quarter of an hour, where your energy goes: hot-water tank, battery or charge point.
You have nothing to remember and nothing to set. The software comes with your installation, with no subscription.
Every kWh you use instead of exporting is straight saving. The software shifts boiler, battery and charger to the hours your panels are producing.
Your bill depends partly on your highest quarter-hour peak. Peak shaving absorbs that peak with the battery — you don't pay for one moment when everything ran at once.
When prices are low or even negative the battery charges; at expensive hours your home lives on what it stored.
Our software, supplied with your installation. No monthly licence, no third party holding your data or your controls.
For as long as your meter ran backwards, nobody had to think about timing. What you generated at midday you simply took back in the evening. The hour at which you switched something on made no difference.
That is over. Today there are two prices: a low one for what you export and a high one for what you draw. The hour at which your hot-water tank or your car starts working is therefore suddenly worth money.
That is precisely what controls do: shift your usage to the right hours. Every day, without you thinking about it.
Every quarter of an hour the software sees how much your panels are generating, how much your home is using and how full the battery is. On that basis it chooses where your electricity goes.
If there is a surplus, it goes to the hot-water tank, the battery or the car instead of to the grid. If there is too little, your home lives off what it stored earlier. If output falls away, you get a signal rather than a surprise on your annual statement.
| Component | What happens automatically |
|---|---|
| Hot-water tank | Heats during the sunny hours instead of in the evening at the full rate. |
| Home battery | Charges on your surplus and supplies in the evening, and absorbs your quarter-hour peaks. |
| Charge point | Charges more slowly and at the cheapest moments, so your peak does not go up. |
| Monitoring | Reports a drop in output, so a fault does not go unnoticed for months. |
Part of your grid charge is calculated not on how much you use, but on your highest quarter-hour peak. If you cook while the tumble dryer is running and the car is charging, that single quarter of an hour sets your monthly peak — even if it happens only once. In 2026 a minimum of 2.5 kW is applied.
Controls flatten that peak by not letting everything come on at once. You therefore no longer have to plan a household around your meter. Read also the capacity tariff explained.
It follows generation, usage and battery level in real time, and shifts usage to the moments when there is your own electricity available.
It watches your quarter-hour peaks, which bear directly on the capacity tariff.
It warns when output falls away, so a faulty panel does not go unnoticed for months.
Because we fit and maintain the installations ourselves. When something goes wrong, we want to see it before the customer rings.
Dynamic charging and control based on hourly tariffs: [TO BE CONFIRMED]. We publish no claims on this before the features are confirmed.
No. The software comes with your installation. No monthly licence, and no third party holding your data or the control of your home.
Your generation, your usage and the state of your battery, with the energy flows at that moment. The images on this page are a representation of the app; we will supply the final screens: [TO BE CONFIRMED]
That depends on your current inverter and meter. Which existing installations we can connect to our controls: [TO BE CONFIRMED]
Yes. The software works automatically — that is the point — but you can always step in yourself, for instance charging the car fully straight away.
