Thanks to the combination of the Solar-Log™ and the EGO Smart Heater, surplus PV power can be used to heat water which can also be used later when stored in combination storage tanks. The heating elements are activated to operate at different levels from 0 to 3500 watts depending on the amount of surplus power. This combination increases the degree of self-sufficiency, especially in the summer and in transitional periods when there is a high amount of surplus PV power. During this time, no fossil fuels are needed for the conventional heating of warm water. The minimal temperature for the hot water heater can be defined in the device configuration. This will ensure that there is always 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.
Solar-Log™ is compatible with my-PV AC ELWA®.
