Your Tesla, charged on the cheapest hours. Automatically.
kilowatts watches your dynamic electricity tariff so you don't have to. It plans your charging into the cheap hours, soaks up your solar surplus, and shields you from evening price peaks — then shows you the receipt.
For Tesla (and Powerwall) owners in Europe on dynamic tariffs:
🌙
Cheap Hours
Every afternoon when tomorrow's prices land, kilowatts writes the cheapest window into your car's own charge schedule. One command a day — your car never gets woken up.
☀️
Sun Soak
Exporting solar for cents while your car sits at 60%? When your Powerwall reports a real surplus, it goes into the car instead.

Peak Guard coming later
When the expensive evening hours hit, your home runs from the Powerwall instead of the grid. Tell us if you need it.
🔌
Grid Rescue coming later
Grid overvoltage tripped your inverter? Start charging, drag the voltage down, solar comes back. We're validating demand — tell us if you need it.
First month free — no card, no auto-charge. Then €3/month or €30/year.
Costs and margin published: Stripe €0.32 · Tesla API €1.50 · infrastructure €0.18 · our margin €1.00. That's the whole business model.
