Charge controller for 20 A Solar Panels and USB outputs

Charge controller for photovoltaic applications controlled by a microcontroller and capable of operating automatically at both 12 and 24 V. It has a graphic LCD display, two 5 volt / 2 A USB outputs, control buttons and screw terminal block (for battery, load and solar panel). It allows to supply the right degree of current to the batteries, protecting them from an excess discharge or charge with the aim of prolonging their life cycle as much as possible.

Attention! use only with 12 and 24 V solar panels.

Technical features

·       Protects the battery from polarity reversal.

·       It automatically goes into protection and stops when the load current exceeds the range of the regulator.

·       In case of short circuit it enters into protection.

·       Overload protection.

·       To avoid the complete discharge of the battery, the regulator will automatically disconnect the load at a certain voltage which cannot be less than 10.7 V for the 12 V battery and 21.4 V for the 24 V batteries.
