Фотоелектричний контролер/інвертор нагріву води

The KTR4 controller is intended for powering electric resistance heaters with a power of 1 to 5 kW from photovoltaic modules up to a power of 7 kWp in hot water storage tanks.

The voltage from the photovoltaic modules is connected to the input and it is converted into alternating voltage in the device. The microprocessor controls so that the maximum possible power (MPPT) of the solar generator is delivered to the resistance heater.

The controller has two power outputs:

        output 1 is connected to the primary heater

        output 2 is connected to the heater which uses the  

         residual energy.

The controller has two temperature measuring inputs. Each of the inputs is connected to the temperature sensor PT1000 in the heating device.

The integrated temperature controller ensures that the temperature in the heating device is not higher than the set maximum temperature.
