The new power controller AC-THOR 9s can control both electrical room heating and water heaters up to 9 kilowatts of power linearly. It controls three-phase heating elements or up to three electrical heat sources and can even supply several heating circuits and regulate them independently of each other.
Because it communicates with inverters, battery systems and smart home controls, the intelligent power controller always knows exactly how much excess solar power is available. In energy-optimised buildings, the device replaces the entire fluid-based heating technology. Missing energy comes from the grid. Alternatively, the solar power manager can also be integrated in conventional buffer storage tanks. The new power controller is no larger than its “little brother” AC-THOR, which my-PV launched in 2017 for detached and multi-family homes.
