Make the most of solar energy and increased self-consumption
AC ELWA-E
AC ELWA-E is a 0 - 3 kW linearly controlled water heating device for grid-connected photovoltaic systems. It uses excess PV energy for hot water heating and thus optimizes the self-consumption of the system. The linear control of the power sets the PV feed-in power to zero. The AC ELWA-E also has our proven hot water boost-backup function: if the sun does not seem to be enough, the hot water can optionally be heated to the desired temperature by using energy from the public power grid. It can be installed in hot water boilers and buffer storages.
Advantages of AC ELWA 2
Self-consumption increases significantly
Easy communication via network cable or powerline
Heating power is linearly controlled
Practically no energy is fed into the grid
Installation in hot water boilers and buffer storage possible
Flexible control by various inverters, battery systems and Smart Homes
