Technology overview -
Energostat
A small box next to the inverter. It sends surplus power to your car, water heater, pool and heat pump.
How it works
Energostat, our own product
Use at home what would otherwise go to waste.
A small box next to the inverter keeps track of how much spare energy you have and sends it to your car, water heater, pool or heat pump. Without it, the surplus would flow into the grid for next to nothing, or off-grid it would simply be wasted.
-
Watches the surplus
When the panels produce more than the house uses, it sends the surplus to the car, water heater, pool or heat pump. It adds and trims power as the sunshine comes and goes.
-
Never drains your house
The home battery keeps a reserve for the night, 30% by default. Below it, appliances are never powered from the battery. It watches the main breaker too: switch on the oven and it cuts back.
-
Charges by the time you set
Say 80% by 7:00. It uses solar power until the last moment and tops up only the shortfall another way.
-
Decides on site
It switches appliances via contactors and makes every decision in your home; it needs no internet to run. It always shows why something is running.
Surplus 4.2 kW. Charging the car and heating water.
Illustrative data
What it controlsElectric car, water heater, pool and heat pump. Other appliances connect via a contactor.

We build it, connect it and keep watch.
Every installation we build reports to HELIOS, the monitoring centre we built on top of Victron VRM. We see output, battery status and faults in real time. We usually know about an outage before you do.

News
What's new with us.
All news-
We turned an old Tesla charger into a smart wallbox
The 2019 Tesla Wall Connector can do just one thing: send power to the car. With Energostat it now charges from the sun, follows the home battery's state of charge and works without the cloud. We didn't change the wallbox at all.

Our new website and HELIOS monitoring
We've launched our new website in Czech and English. It covers the equipment we build on, our Energostat and HELIOS, the monitoring centre that keeps an eye on our customers' installations remotely.

Introducing Energostat: use your rooftop surplus at home
Energostat is our own control box for solar systems with Victron equipment. It sends surplus power to your car, water heater, pool or heat pump instead of exporting it to the grid for next to nothing.
