EPEVER XTRA3415N G3 Solar MPPT Controller 12/24/48V XDS2 30A, 150V Input

EPEVER XTRA3415N G3 — Solar MPPT Controller

Managing energy in solar systems can be challenging, especially when you want to maximize efficiency and protect your batteries. The EPEVER XTRA3415N G3 is a high-performance solar MPPT controller offering a Maximum Power Point Tracking (MPPT) efficiency of ≥99.5%, ensuring you harness the maximum available solar energy even under varying light conditions. The controller is compatible with 12/24/36/48 V DC battery systems and supports charging and discharging currents of up to 30 A, making it an ideal choice for a wide range of applications. Thanks to advanced features—such as adaptive three-stage charging and support for various battery types, including lithium—it delivers reliable performance and extends battery lifespan.

Maximum Efficiency and Flexibility

The controller utilizes MPPT technology to track the maximum power point with high precision, which is crucial for optimizing solar panel performance. With a wide MPPT voltage range (battery voltage +2 V) up to 108 V and a maximum open-circuit voltage of 150 V, the device is highly flexible and adapts to diverse solar system configurations. The ability to power the load directly without a connected battery ensures efficient operation even when storage capacity is limited.

Protection and Reliability

The EPEVER XTRA3415N G3 is designed with a focus on the safety and protection of your system. It offers automatic temperature compensation for lead-acid batteries, minimizing the risk of overcharging and enhancing reliability. An IP33 rating protects the device against dust and splashing water, while comprehensive electronic safeguards provide protection against overvoltage, reverse polarity, and short circuits. The controller operates fully within a temperature range of -25°C to 45°C, making it an ideal choice for diverse climatic conditions.

Monitoring and Management

With an integrated RS-485 communication interface, you can easily monitor and configure the controller remotely, enhancing convenience and control over your solar system. Support for optional 4G or Wi-Fi modules enables even broader management capabilities. An LCD display with an adjustable backlight duration (up to 999 s) shows key operational data, facilitating system management and diagnostics. ### Technical Specifications
