Yes, there is a charging rule that allows you to configure that charging should only take place if the solar power system delivers a certain minimum power. The cFos Charging Manager can read generation counters, SMA inverters and inverters that support SUNSPEC. More will follow. You can also test yourself
whether the Charging Manager already supports your solar installation.
There is a charging rule in the integrated Charging Manager with which you can set that the electric car should only be charged from a certain solar power. In addition, you can set in different variations the power with which charging should then be carried out. The cFos Charging Manager also supports excess solar
What we currently do not support is the automatic switch-on and switch-off of individual phases if the solar power drops below 4200 W. To do this, we would have to be able to switch the phases individually using separate contactors. We are considering providing a retrofit kit for the cFos Power Brain Wallbox
. But that won't be possible before 2022.Here is a workaround
: If you know that the solar system delivers less than 4200 watts, you can switch off one or two fuses (circuit breakers) that are used to protect the supply lines to the wallbox (but not the ones with which the cFos Power Brain Controller
is protected). However, you must not switch individual phases on or off during the charging process!
