Weekly schedule
Pick charging slots day by day and hour by hour: they apply to all your controlled batteries.
Off-peak charging
In winter, charge your batteries off-peak and use them at peak times
In winter your panels no longer fill the batteries. TED recharges them from the grid during off-peak hours, and the house uses them during peak hours.
Sounds familiar?
- From November to February your batteries stay empty most of the time.
- You pay peak rates while storage capacity sits unused.
- Scheduling charging in each manufacturer app is tedious, or impossible.
Why it is hard
Charging from the grid means coordinating every battery on the same time slots, without exceeding your supply capacity, then returning to normal regulation.
Time slots depend on your contract, and each brand's app has its own way (or none) of scheduling a charge.
The solution
The features involved
Automatic off-peak hours (France)
For French contracts, your off-peak hours (via MyElectricalData) and Tempo day colours can be fetched automatically, to charge at the right time without a schedule to maintain.
Within your limits
Charging respects the maximum charge power you set and each battery's maximum level.
Automatic return
Outside the slots, normal regulation resumes, or everything stays on standby if nothing is useful.
Getting it running

In the settings.
- 2
Choose where slots come from
Your weekly schedule, or (in France) your contract's off-peak hours.
- 3
Set the charging power
Taking into account your supply capacity and the rest of the house.

Frequently asked questions
Does it pay off?
It depends on the price gap between peak and off-peak rates in your contract and on your batteries' efficiency. You choose the slots: you stay in control of the strategy.
Does it work outside France?
The weekly schedule works everywhere. Automatic off-peak detection covers French contracts.
Other problems solved
Zero export and maximum self-consumption with batteries
Surplus exported at noon, imports in the evening: keep the grid close to 0 W, continuously.
