We handle the grid company for you
One MitID signature lets us ask. It costs nothing and does not bind you.
How it works
You sign
With MitID. You get a copy by email straight away.
We fetch data and ask the grid company
May a battery export power to the grid from your connection, and how much?
The grid company answers
Grid companies are busy, so it can take several weeks. We will write to you if it drags on.
You get the answer and a concrete number
Then you decide. No commitment before an actual agreement.

What can our connection earn?
Up to the amount the calculator shows, in the first years, paid as a monthly share of the battery's profit. The final figure depends on how much your grid company allows the connection to export, and on the electricity market. The grid review gives you a concrete number.
Does our connection need room to spare?
No. What matters is how much your grid company allows a battery to export to the grid from your connection. The grid review finds out.
What does it cost us?
You pay nothing for the battery, its installation or its operation. ZynexGroup pays for, builds, owns and operates it. You provide a space on your site and receive a monthly share of the profit.
What does the grid company decide?
Whether, and how much, a battery may export power to the grid from your connection. The answer decides how large an installation can stand on your site.
How long does the grid review take?
It varies. Grid companies are busy, so the answer can take several weeks. We will write to you if it drags on.
What if your connection is smaller?
This tool does not have a waitlist. Contact us if you would like to discuss whether a smaller connection could be relevant.
What happens with our data?
Address and CVR searches are sent to the server for lookup, and lookup data may be cached. To create a PDF, the selected setup and any address are sent to the server; downloading it requires no name, email or consent and does not create an enquiry. If you arrive from the electricity analysis, the calculator receives the selected connection and address plus a short-lived reference to check any existing permission; it does not fetch or display historical meter time series. The six-month period mentioned in the draft document is a proposed term for a grid review and does not describe PDF downloads.
