EPEVER 40A MPPT Solar Charge Controller 12V/24V Auto Voltage Detection, Negative Ground, Compatible with Lead-Acid & Lithium Batteries - Perfect for RV, Marine, Off-Grid Solar Systems

The Tracer AN series is based on common negative design and advanced MPPT control algorithm, with LCD displaying running status. Improving the MPPT control algorithm further, Tracer AN series can minimize the maximum power point loss rate and loss time, quickly track the maximum power point of the PV array and obtain the maximum energy from solar modules under any conditions; and can increase the ratio of energy utilization in the solar system by 10%-30% compared with a PWM charging method. The limitation function of the charging power and current and reducing charging power function automatic improve the stability which works even connecting oversize PV modules and in high temperature, and increase the professional protection chip for the communication port, further improving the reliability and meeting the different application requirements. With the adaptive three-stage charging mode based on a digital control circuit, Tracer AN series controllers can effectively prolong the life cycle of batteries, significantly improve the system performance and support all-around electronic protection functions, minimize damages to components of the system caused by incorrect installation or system failure at the utmost, and effectively ensure safer and more reliable operation of the solar power supply system for a longer service time. Ultra-fast tracking speed and tracking efficiencyCharging power and current limitation functionCompatible with lead-acid and lithium-ion batteriesReal-time energy statistics functionOverheating power reduction functionMultiple load work modesThe communication port adopts professional protection chip, which can provide 5VDC power supply, and has over-current and short-circuit protection.With RS-485 communication bus interface and Modbus communication protocol, it is available to meet various communication requirements in different situations. While wiring the controller do not close the circuit breaker of fuse and make sure that the leads of "+" and "-" poles are connected correctly.A fuse which current is 1.25 to 2 times the rated current of the controller, must be installed on the battery side with a distance from the battery not greater than 150 mm.If the controller is to be used in an area with frequent lightning strikes or unattended area, it must be installed an external surge arrester.If an inverter is to be connected to the system, connect the inverter directly to the battery, not to the load side of the controller.
