The optimization feature “PV excess to PV immersion heater” allows you to exploit the full potential of your self-produced PV power. If the heat pump, the household and other devices in the system no longer require energy, the battery (power storage system) is sufficiently charged and there is still a PV excess, it will be available for PV immersion heater. This maximizes self consumption before feeding into the public grid begins.
The optimization feature can be enabled and disabled in the ViCare app as needed. It is possible to activate it at short notice if there is still a PV excess available, but it is too low to be used for the heat pump, for example.
Note: “PV excess to PV immersion heater” and the holiday program in the ViCare app should not be active at the same time.
