Grid calculator

Run the numbers before you run the cables

Put in your peak, your connection limit and the quote the DSO gave you. The site plan and the numbers move together, and you land on the storage that covers the gap.

1
Enter your peak, your grid connection limit, and how long the busy period lasts
2
Add your chargers and your solar, then the quote and the waiting time the DSO gave you
3
See which path wins, what it costs, and which cabinet covers the shortfall
