01
Contract and documents
Your flex contract and the paperwork we need to start: grid operator details, signed mandates, the technical drawing of your site.
HOW IT WORKS
You and your installer follow every step on the same dashboard: what is done, what comes next and who does it
PHASE 1 · GETTING CONNECTED
1
Contract and documents
Your flex contract, your energy contract for both consumption and injection, your grid operator details, signed mandates and the technical drawing of your site. The energy contract matters from day one: it decides how far the battery can be optimised, and sometimes it should change first.
We chase and check
2
Grid operator
Your installer files the technical dossier and the test results with your grid operator, through their portal where one exists. We follow the file and step in when it stalls, so nothing sits waiting on a form.
Your installer files, we follow
3
Gateway
The device that connects your site to the markets. It is ours, we bring it, and it can go in before the battery is even hanging. Plugged in on site, configured remotely by us.
We supply and configure
4
Installation
Your installer places the battery and connects everything the market connection depends on: inverters, meters, fixed addresses and settings. Not only the battery. This is where projects usually lose weeks.
Your installer connects
Your flex contract and the paperwork we need to start: grid operator details, signed mandates, the technical drawing of your site.
We move approvals through your grid operator's portal. You see the status; we handle the back-and-forth.
Your installer connects the battery. We confirm validation with the grid operator and manufacturer before moving on.

PHASE 2 · GOING LIVE
5
Datasheet
One document that collects the technical details of every device on site. We need it to make the integration work, and without it the next steps cannot start.
Together, we supply the form
6
Commissioning
Two inspections, not one. The manufacturer checks that the battery is installed correctly and your grid operator inspects the connection. Only after both does the administrative process start that ends in your connection contract and your limits.
Your installer hosts both
7
Technical Integration
Your battery starts talking to our platform, tested against real market signals before a single euro is on the line.
We integrate and test
8
Go-live
Your site starts earning on its own meter first, and joins the energy markets as each approval lands. From then on, you get a report every week.
We coordinate, settle and report
A question we get every week
It is ours, and no. FlexHub supplies no other hardware and does no installation work. The gateway is how your site is read and connected to the markets. Everything physical stays with your installer, including the margin on it.
