Solar PWM controller GETI GSR020 12-24V/20A

Product detailed description

Solar PWM controller Geti GSR020
Solar PWM controller Geti GSR020 with indication of charging, current draw and battery voltage. Designed for system voltage 12V or 24V with fixed operating parameters and maximum charging and load current of 20A for panels up to 240W-12V or 480W-24V.
Brief description of PWM controllers: solar PWM controllers connect solar panels directly to the battery to be charged and after reaching the set or given battery terminal voltage, the subsequent regulation is solved by pulse current limiting-interruption. This happens in frequency units of up to tens of kHz and is indicated by an LED. The regulators are suitable for panels with identical system voltage as the battery voltage, otherwise losses occur when part of the power is wasted due to inappropriate V-A characteristics of the panel.
