Solar & system controllers

Solar controller DeltaSol<sup>®</sup> AL E HE

Solar controller DeltaSol® AL E HE

The DeltaSol® AL E HE controller is especially designed for standard solar systems with a high-efficiency pump and an electric backup heating. It is equipped with a PWM output and two high-current relays to which an electric immersion heater of up to 3 kW (230 V~) can be connected. The heater can be directly connected to the controller without the need of auxiliary relays. For data communication, the controller has a RESOL VBus®.
