Astrel 4-noks Pro is a PV support system for three-phase solar panel systems that allows you to track the amount of solar energy you produce and consume (and change your energy consumption habits based on it), but most importantly, use the built-in relay to transfer the excess solar energy you produce to an electric heating element or heat pump.

This function is used in this hot water kit, which consists of an 4-noks Elios4You Pro control module, a Kospel SW 300L hot water tank with a 1.5 m2 heat exchanger for connecting an additional high temperature heating system (e.g. gas boiler) and a flanged electric heating element with 4.5 kW or 6 kW output.

This set can be easily integrated into an existing heating system or used as a basic element in a new system.
