12-24V/10A+USB PWM Solar Controller for Pb Batteries, LiFePO4, and Li-ion

Product detailed description

The PWM controller allows for charging lead-acid batteries with a current of up to 10A and connecting PV panels with a maximum output voltage of 25V (for a 12V system voltage). It is equipped with an LCD display for setting and viewing 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.
