Solar PWM controller 12-24V/20A+USB for Pb batteries, LiFePO4, Li-ion

Product detailed description

PWM controller allows charging of lead-acid batteries with current up to 20A and connection of PV panels with output voltage max. 25V (for system voltage 12V). It is equipped with LCD display for setting and displaying operating parameters.

Brief description of PWM controllers:
PWM solar 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 limitation-interruption. This happens at a frequency of units up to tens of Hz and is indicated by the flashing of an LED marked "charge" or "solar" in some controllers. Regulators are suitable for panels with a system voltage identical to the battery voltage, otherwise losses occur when part of the power is wasted due to inappropriate V-A characteristics of the panel.
