EPEVER TRC3210 — High Efficiency MPPT Solar Controller

For solar system users looking for an efficient and reliable way to charge batteries, the EPEVER TRC3210 controller is the ideal choice. With the new generation MPPT algorithm, the maximum tracking efficiency reaches up to 99.5% and the conversion efficiency 98.4%, which minimizes energy losses and increases system performance. Automatic battery voltage detection (12V or 24V) and the ability to directly power the load via battery-free mode provide flexibility in various applications. In addition, with low standby power consumption (less than 10mA), this controller is ideal for autonomous systems with limited power availability.

Performance and Efficiency

The TRC3210 controller excels in high charging efficiency, allowing you to maximize the use of solar energy. It supports charging and discharging current up to 30A, which allows stable operation even under higher loads. The maximum charging power reaches 390W at 12V and 780W at 24V, which is ideal for small and medium-sized solar installations. MPPT voltage range from (battery voltage + 2V) to 72V ensures optimal tracking of the maximum power point even under variable conditions.

Compatibility and installation flexibility

This model is compatible with a wide range of batteries, including LiFePO4, AGM, Gel and flooded batteries, allowing you to choose the battery type according to your specific needs. With support for parallel operation, the system capacity can be expanded when using multiple units. The choice of communication interface — 2× RS-485, RS-485 + CAN (RV-C) or RS-485 + LIN (CI-BUS) — facilitates integration into various systems. An optional 4G/Wi-Fi module is available for remote monitoring, ideal for users who need to access data from anywhere.

Reliability and operating conditions

The TRC3210 controller is designed for long-term and reliable operation even in harsh conditions. It operates over a wide temperature range -30 °C to +60 °C, while maintaining full performance down to 40 °C. With an IP32 rating, it is suitable for installations in protected environments, such as in motorhomes or technical rooms. The maximum altitude without derating is 2,000 m, ideal for mountain installations.
