Solar Charge Controller - 20A DC12V Solar Cell Panel Charge Controller Battery Charge Regulator

General Description

The 20A DC12V solar charge controller is designed to regulate the charging of batteries from solar panels. It offers protection against short circuits, overloads, over-discharges, and undervoltages, thus ensuring safe and efficient operation of your solar system.

Technical Specifications

• System Voltage: DC12V
• Nominal Charging Current: 10A
• Maximum Charging Current: 16A
• Maximum Open-Circuit Voltage of the Solar Cell: 25V/36V
• Operating Temperature: -20℃ to +50℃
• Controller Self-Consumption Power: 10mA

Installation

• Open the top cover of the controller and connect according to the illustration on the cover.
• Connect the "+" and "-" terminals of the battery to the corresponding terminals (third and fourth terminals from the top). left).
• Connect the "+" and "-" terminals of the solar panel to the corresponding terminals (first and second terminals from the left).
• Connect the "+" and "-" terminals of the load to the corresponding terminals (fifth and sixth terminals from the left).

Operation

• The charging indicator light shows the charging status: on for a strong charge, flashing for a float charge, off for a stopped charge.
• When the light is on, it means there is an output and the load can operate; If it is off, this means there is no output.

Other Information

• This product is suitable for 17V lead-acid batteries and solar panels.
• Before connecting, check that the rated voltage of the solar panel, battery, and load is correct.
• The rated current of the solar panel and load must not exceed the rated current of the controller.
