My-PV AC•THOR 9s is a linearly controllable 0 - 9 kW solar power transmission unit that can be used for hot water boilers, storage tanks and even for controlling electric heating circuits (up to 3 electric consumers). Its operation depends on the solar energy available and the amount of heat required.

This equipment can be used to provide part or, for energy-efficient homes, all of the energy needed for hot water and heating, or to support existing heating systems (by connecting to a storage or multifunctional tank). It obtains the missing energy from the common grid. 

This control unit can be used to control several heating elements, which can also be used to quickly reach the operating temperature of large-volume tanks and achieve a stratification effect in them. In such a scheme, the heating elements will operate in a combination which achieves the operating temperature most quickly (see below). 

Main product advantages:

• Linear power control from 0 to 9 k, depending on the solar energy available;
• 3 controllable outputs, for up to 3 power connections;
• Neutral output for connection to a three-phase heating element;
• Tank heating possible with 3 x 3 kW heating elements or with one 9 kW three-phase heating element;
• Possible energy transfer to heat pumps;
• Up to two electric heating circuits (see below) can be powered;
• Easy installation, maintenance, takes up little space in the utility room;
• Compatible with most inverters, battery chargers and Smart Home systems on the market;
• Up to 85% self-generated solar energy even without a battery charger - minimise the amount of solar energy transferred to the grid!

My-PV AC•THOR 9s can be purchased individually, as a bundle with three 3 kW heating elements or as a bundle with one 9 kW three-phase heating element (in both cases with an thermostat). In all variants, it comes with a My-PV WiFi meter.
