Thanks to the combination of the Solar-Log™ and the EGO Smart Heater, surplus PV power can be used to heat water, which can be used later when stored in combination storage tanks. The output is adjusted to 0 to 3500 watts in 500-watt steps depending on the amount of surplus. This combination offers savings potential and increases the degree of self-sufficiency, especially in the summer and in transitional periods when there is a high amount of surplus PV power. Thanks to this stored surplus power, no fossil fuels are needed by the water heater boiler. The minimal temperature for the broiler can be defined in the device configuration. This will ensure that there is enough warm water available regardless of the amount of surplus PV power. The EGO Smart Heater can be conveniently configured from the Solar-Log™ web interface.
There are two EGO Smart Heater; the difference is in the connection options. The heating rod is available with an Ethernet connection or a direct RS485 interface for the connection to the Solar-Log™ device. However, the RS485 is required exclusively for the Solar-Log™ connection.
