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

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

Brief description of PWM controllers:
Solar PWM controllers connect the solar panels directly to the battery being charged, and after reaching the set or given terminal voltage of the battery, the subsequent regulation is solved by pulse limitation-interruption of the current. This happens at a frequency of units to tens of Hz and on some controllers is indicated by a flashing LED labeled "charge" or "solar". Regulators are suitable for panels with the same 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.
