EPEVER Tracer2206AN G3 MPPT Solar Regulator 20A, 12/24V, Input 60V

Advanced MPPT solar charge controller with adaptive 3-stage charging for maximum solar energy utilization.

The Tracer-AN G3 solar charge controller represents a new generation of MPPT controllers from EPEVER. It utilizes adaptive 3-stage charging that maximizes energy utilization from photovoltaic panels and extends battery life. The controller features a constant voltage output function that ensures comprehensive and user-friendly compatibility with various types of lithium batteries.

Under certain conditions, the photovoltaic system can power loads directly without a battery. Excellent low-power consumption design significantly reduces standby power consumption and extends system operating time. The controller is ideal for applications such as RVs, residential systems, and outdoor monitoring.

Advanced charging and battery protection
The controller utilizes adaptive 3-stage charging that optimizes the charging process according to the current battery state. Temperature compensation ensures correct charging voltage at different operating temperatures. The stable self-activation function enables automatic system operation recovery.

Flexible communication and control
Parameters can be set via PC software, mobile app, or remote meter. The RS-485 communication interface with 5 V DC/200 mA output (RJ-45) allows connection of optional 4G or Wi-Fi modules for remote monitoring and system management.

Comprehensive system protection
Electronic protection includes protection against overload, short circuit, overvoltage and undervoltage. LCD display with adjustable backlight (default 60 s, range 0–999 s) provides clear information about system status. IP30 rating ensures protection of internal components.
