PV heating element

ELWA

ELWA is a 2 kW photovoltaic water heating device. The electricity from the photovoltaic modules is fed
into the heating element without any loss. The device runs in pure island operation and is supplied by
the PV generator, no connection to the power grid is necessary.The desired hot water temperature is set
with a rotary knob, LED displays provide information on the current device status

AC ELWA-E

AC ELWA-E is a 0 - 3 kW steplessly regulated hot water heating device for grid-connected photovoltaic systems. Excess PV energy is used to prepare the hot water, thereby optimizing your own use of your photovoltaic system.

The AC ELWA-E also has a hot water safety device: if it is too cloudy that your PV system cannot produce enough energy, the water is brought to the desired temperature using energy from the public power grid.
