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

Product detailed description

Solar PWM controller Geti GSR020
Solar PWM controller Geti GSR020 with charging indication, current draw and battery voltage display. Designed for a system voltage of 12V or 24V with fixed operating parameters and a 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 being charged, and once the set or given terminal voltage of the battery is reached, subsequent regulation is handled by pulse limiting-interrupting the current. This occurs at a frequency of units to tens of kHz and is indicated by an LED. The controllers are suitable for panels with a system voltage matching the battery voltage, otherwise losses occur, where part of the power is wasted due to the unsuitable V-A characteristics of the panel.
