EPEVER XTRA3215N G3 Solar MPPT Controller 12/24V XDS2 30A, 150V Input

EPEVER XTRA3215N G3 — High-Efficiency MPPT Controller

For users seeking a reliable way to manage solar battery systems, the EPEVER XTRA3215N G3 controller offers a combination of cutting-edge technology and robust design. Thanks to MPPT technology with a tracking efficiency of at least 99.5%, it maximizes energy harvest from solar panels, even under changing light conditions. With automatic 12/24 V voltage detection and a maximum charging current of 30 A, it provides flexibility for a wide range of battery applications. An IP33 rating and an operating temperature range of -25 to +45 °C ensure reliable operation even in demanding outdoor environments.

Maximum Charging and Battery Management

The EPEVER XTRA3215N G3 supports adaptive three-stage charging, which optimizes battery performance and lifespan. Automatic temperature compensation is ideal for lead-acid batteries, while the lithium battery activation function enables the safe use of modern LiFePO4 systems. A wide MPPT voltage range (battery voltage + 2 V to 108 V) ensures efficient charging across various configurations.

Protection and Durability

The controller features advanced electronics that provide protection against overload, short circuits, reverse polarity, and overheating. A constant output voltage function allows the load to be powered directly from the solar panels, which is useful in situations where no battery is connected. With an IP33 rating, the device is protected against the ingress of solid particles and water spray, enhancing its reliability for outdoor use.

Connectivity and Remote Monitoring

An RS-485 interface allows for the connection of optional 4G or Wi-Fi modules, enabling remote system monitoring and management via an app. The clear, backlit LCD display provides real-time system status information and can be configured for display duration (default: 60 s; range: 0-999 s). ### Technical Specifications
