Yes. There is a charging rule that you can use to configure that charging should only take place when the solar system delivers a certain minimum output. The cFos Charging Manager also masterssolar excess
charging. For this purpose, the cFos Charging Manager can read out production meters and/or access the inverters of the solar system directly. For example, many inverters from SMA 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 currently do not support is the automatic switching on and off of individual phases when the solar output 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 or conversion kit for the cFos Power Brain wallbox. But that 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) 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!
