2022 EPEVER Tracer-AN series mppt solar charge controller is new upgraded version , Better funcations and advanced technology .

Added Features ：

Blacklight LCD Display ; More Safety Protection Functions ;
Compatible with lead-acid and lithium-ion batteries too ;
2022 Upgraded version support adjusting Lithium types by controller buttons directly . You could also contact vendor ( Goland Century ) services to get program firmware upgrade file , then you could set old version controller's Lithium types by controller buttons too .

Product Features:

Based on common negative design and Advanced MPPT technology, with efficiency no less than 99.5%,Ultra-fast tracking speed and tracking efficiency ;
With the adaptive three-stage charging mode based on digital control circuit, Tracer-AN series controllers can effectively prolong the life-cycle of battery and significantly improve the system performance. The load, utility or generator auto-control relays make it easy to compose the hybrid power system;
All-around electronic protections, including overcharging, over discharging, PV reverse polarity protection, effectively ensure the safer and more reliable operation of the solar system for longer service time;
The isolated RS485 interface with standard MODBUS communication protocol, easy for customer to monitor and set the parameters via mobile phone APP or PC software;
This modular solar controller can be widely used for different applications, e.g.solar RV, Communication base stations, household systems, and field monitoring, etc.

Protection function :

•PV Over Current/power protection • PV Short Circuit protection • PV Reverse Polarity protection
• Night Reverse Charging protection • Controller Overheating protection
• Battery Reverse Polarity protection • Battery Over Voltage protection
• Battery Over Discharge protection • Battery Overheating protection
• Lithium Battery Low Temperature protection
• Load Short Circuit protection • Load Overload protection
•TVS High Voltage Transients protection

CONNECTION DIAGRAM

Battery must be connected first ! Never connect soalr panel array to controller Without/Before connect battery.
DO NOT connect any inverter/wind/Alternator or Charger into the charge controller directly ! You should connect with battery and add fuse .
If there is a long distance between the PV array and controller or between the controller and battery, larger size wires should be used to reduce the voltage drop and improve performance. (Recommended wire size is only for reference.)

How to program for Lithium Battery parameters ？

Via Remote Meter (Accessories needed: MT50)
Via Phone APP [ Android or IOS], (Accessories needed：WIFI Adapter or BLE Adapter )
Via PC Software (Accessories needed RS485 cable :CC-USB-RS485-150U ) , Software download : EPEVER official website or read in manual .
