A solar controller is an electronic device that controls the circulating pump in a solar hot water system to harvest as much heat as possible from the solar panels and protect the system from overheating. The basic job of the controller is to turn the circulating pump on when there is heat available in the panels, moving the working fluid through the panels to the heat exchanger at the thermal store. Heat is available whenever the temperature of the solar panel is greater than the temperature of the water in the heat exchanger. Overheat protection is achieved by turning the pump off when the store reaches its maximum temperature and sometimes cooling the store by turning the pump on when the store is hotter than the panels.

This system works at its best during any time of the day at any kind of sunlight. The induction motor has very high starting current which is around four times of the running current of the motor. The VFD in controller eliminates the high starting current of the induction motor. Because of the smooth start using VFD, the motor will start as early as even 9am and works till 5:30pm. It delivers maximum water during 10am to 4pm.
