Yes, there is a charging rule with which you can configure that charging only takes place when the solar system delivers a certain minimum power. In addition, the cFos Charging Manager can handle solar surplus charging
. For this purpose, the cFos Charging Manager can read out generation meters and/or directly access the inverters of the solar system. Many SMA inverters and inverters that support SUNSPEC are supported. We are constantly adding more devices to the list. You can also test yourself
whether the Charging Manager already supports your solar installation.
What we do not currently support is the automatic switching on and off of individual phases when the solar power drops below 4200 W. This would require us to be able to switch the phases individually using separate contactors. For this, we would have to be able to switch the phases individually using separate contactors. We are considering providing a retrofit kit or conversion kit for the cFos Power Brain Wallbox. However, this will not 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) with which the supply lines to the EVSE are protected (just not the one with which the cFos Power Brain Controller is protected). However, you must not
switch individual phases on or off during the charging process
