With the help of a Raspberry Pi and the cFos Charging Manager, you can add two important functions not only to our EVSE, but also to other EVSEes: intelligent load management and solar surplus charging. As an alternative to the Raspberry PI, you can also use a PC with Windows 10.
You have an EVSE and want to retrofit solar surplus charging and load management.
You want to set up a charging park with third-party EVSEs and your grid connection does not support all EVSEs with maximum power. The cFos Charging Manager regulates the charging power of the connected EVSEes as low as your grid connection allows.
You have a charging park with third-party boxes and a solar system and only want to charge with your solar surplus at certain times.
For solar surplus charging, the cFos charging Manager requires reference values for the current. There are two possibilities for this:
