Why KStar through SolarFast?
KStar is the line if you want outage cover and a direct Frank Energie link. On three-phase it stops at 10 kW. That is not a house that always keeps running: heavy circuits can sit outside that limit. We put that in the quote, not in a slogan.
We check your connection and choose single-phase or three-phase. Which circuits stay on during an outage is agreed before install.

How it works
Outage cover up to a limit
On three-phase, outage cover is at most 10 kW. A cooker circuit or EV charger can sit above that. We say so beforehand, not afterwards.
Price is not on the site. Capacity, phase and circuits during an outage come in the quote.

Yes. KStar ALL-IN has a direct Frank Energie link. After install we connect the app.
