EPEVER 40A MPPT Solar Charge Controller 12/24V DC Automatically Identifying System Voltage Common Negative Grounding Compitable with Lead-Acid and Lithium Batteries

The Tracer AN series is based on common negative design andadvanced MPPT control algorithm, with LCD displaying running status.

Improving the MPPT control algorithm further, Tracer ANseries can minimize the maximum power point loss rate and loss time,quickly track the maximum power point of the PV array and obtain themaximum energy from solar modules under any conditions; and can increasethe ratio of energy utilization in the solar system by 10%-30% comparedwith a PWM charging method.

The limitation function of the charging power and currentand reducing charging power function automatic improve the stabilitywhich works even connecting oversize PV modules and in high temperature,and increase the professional protection chip for the communicationport, further improving the reliability and meeting the differentapplication requirements.

With the adaptive three-stage charging mode based on adigital control circuit, Tracer AN series controllers can effectivelyprolong the life cycle of batteries, significantly improve the systemperformance and support all-around electronic protection functions,minimize damages to components of the system caused by incorrectinstallation or system failure at the utmost, and effectively ensuresafer andmore reliable operation of the solar power supply system for alonger service time.

• Whilewiring the controller do not close the circuit breaker of fuse and makesure that the leads of "+" and "-" poles are connected correctly.
• Afuse which current is 1.25 to 2 times the rated current of thecontroller, must be installed on the battery side with a distance fromthe battery not greater than 150 mm.
• Ifthe controller is to be used in an area with frequent lightning strikesor unattended area, it must be installed an external surge arrester.
• Ifan inverter is to be connected to the system, connect the inverterdirectly to the battery, not to the load side of the controller.

• Package List:
• 1 x Solar Charge Controller
• 1 x User Manual

The control you will purchase must meet two conditions

1. The rated current of the controller must be greater than (the power of the solar panel divided by the voltage of the battery)

2. The open circuit voltage of the controller must be greater than the open circuit voltage of your solar panel, and both must be greater than the voltage of your battery
