By combining the Solar-Log™ and the AC ELWA-E from my-PV, excess PV power can be used
to heat domestic hot water or combined storage tanks. The power is linearly controlled by the
Solar-Log Base from 0 to 3,000 W depending on the surplus. This combination increases the degree
of self-sufficiency, especially in summer and during transitional periods. During this time, fossil
fuels can often be completely dispensed with for conventional hot water heating. The minimum
temperature of the hot water tank can be defined by configuring the unit. This means that hot
water can always be provided regardless of the excess PV power available. The AC ELWA-E can be
conveniently configured via the web interface for the Solar-Log Base.
