EPEVER Tracer2210AN G3 MPPT Solar Regulator 20A, 12/24V, Input 100V

Advanced MPPT solar charge controller with adaptive 3-stage charging for maximum photovoltaic system performance.

The Tracer-AN G3 controller represents the third generation of MPPT solar charge controllers from EPEVER with maximum DC/DC conversion efficiency of 98% and advanced MPPT technology with maximum power point tracking efficiency higher than 99.5%. It supports automatic 12/24 V voltage detection and operates in the battery voltage range of 8–31 V.

The device offers a unique constant output voltage function, which allows direct load power supply without a connected battery, extending battery life and reducing standby consumption. The controller is equipped with an LCD display for battery parameter settings, supports temperature compensation and stable self-activation function.

Advanced charging modes
The controller offers several load operating modes including manual control, light control, timer control and combined modes. It supports parameter settings via PC software, mobile application or remote meter.

Battery compatibility
The device supports a wide range of battery types including various lithium variants. Temperature compensation with coefficient -3 mV/°C/2 V (default) ensures optimal charging at different temperatures.

Communication and expansion
RS-485 port with 5 V DC power supply and 200 mA current (RJ-45) enables connection to monitoring systems. Optional 4G or Wi-Fi modules expand remote monitoring and system management capabilities.
