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