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

EPEVER Tracer2206AN G3 — 20A Solar MPPT Controller

Are you looking to maximize energy harvest from your photovoltaic panels while ensuring a long lifespan for your batteries? The EPEVER Tracer2206AN G3 solar controller is designed to efficiently manage battery charging using advanced MPPT technology, boasting a tracking efficiency of over 99.5%. Thanks to adaptive 3-stage charging, it optimizes the charging process and supports compatibility with various battery types, including lithium. With a peak DC/DC conversion efficiency of up to 98%, it minimizes losses and boosts system performance—making it ideal for residential solar systems, RVs, and outdoor monitoring applications.

Efficient Charging and Battery Protection

A key feature of this controller is its adaptive 3-stage charging, which automatically adjusts the charging voltage based on the battery's current state. Temperature compensation is set to -3 mV/°C/2 V to protect the battery during temperature fluctuations and extend its service life. The controller also supports stable self-activation, ensuring automatic system recovery following a power outage.

Communication Interface and Remote Control

For easy system management, the controller features an RS-485 communication interface with a 5 V DC/200 mA (RJ-45) output. This port allows for the connection of optional 4G or Wi-Fi modules, enabling remote monitoring and control via a mobile app, PC software, or a remote meter. The LCD display with adjustable backlight (default 60 s, range 0-999 s) provides clear information on system status and allows for easy parameter configuration.

System Reliability and Protection

The controller features comprehensive electronics that protect the system against overload, short circuits, overvoltage, and undervoltage. An IP30 rating protects internal components from dust, while low self-consumption (under 10 mA) ensures minimal energy loss. Thanks to its robust design and support for a wide operating temperature range (-25 to +45 °C), the controller is suitable for demanding outdoor applications.
