Surplus solar energy charging
Only use the surplus of your solar energy to charge your EV. To minimise your energy returned to grid.
(Remember, EV’s generally require a minimum of 6A (1.4kW) to start charging)
Amina app v2.0.1 (currently the latest) is lacking functionality to support surplus solar energy charging
Amina app v2.1.0 (27 Aug) now supports single phase charging,
I will update the flow below with the new card
The surplus of solar panels is less than 18A in most common cases.
(I have 20 panels and only on 1 day I hit the 18A this year)
So most of the time you want to charge with less than 18A. Which means: 1phase chasing (6-16A)
But the amina app does not have a card to set 1phase charging (only 3phase) charging.
I made a request to the app developer and @amina to add this flowcard to the app.
Below is my flow (which is also usable for other chargers)
- the flows input is the energy level from my meter P1
- a second flow will trigger calculation of the energy every minute using the insight trends reloaded app to provide the mean value over 1 minute (the input)
- The setting over the charger is based on the current settings minus the energy measured (P1). So return (negative) will increase the charger current
