EPEVER XTRA4215N G3 Solar MPPT Controller 12/24V XDS2 40A, 150V Input

EPEVER XTRA4215N G3 — MPPT Solar Charge Controller

Efficient solar charge management is crucial for maximizing the performance of photovoltaic systems. The EPEVER XTRA4215N G3 offers advanced features that ensure optimal solar energy utilization in 12V and 24V systems. Thanks to MPPT technology —featuring a peak conversion efficiency of up to 97.9% and a 40A charging current—it is ideal for professional applications. A wide MPPT voltage range of up to 108V allows for the flexible connection of various solar panel types. Reliable protection, adaptability to different battery types, and remote monitoring capabilities make it an exceptional solution on the market.

Advanced Charging and Battery Management

This controller supports a wide range of battery types, including lithium, gel, and flooded batteries, and offers a special function for the safe activation of lithium batteries. An adaptive three-stage charging mode (bulk, absorption, float) automatically adjusts parameters based on temperature, thereby extending battery lifespan. Maximum charging power reaches 520W for 12V systems and 1040W for 24V systems, enabling efficient energy use even under high loads.

Installation Flexibility and Remote Control

The EPEVER XTRA4215N G3 is equipped with an RS-485 communication port that supports the connection of optional 4G or Wi-Fi modules for remote monitoring and control via mobile apps. The backlit LCD display shows all key operating information and allows the backlight duration to be set between 0 and 999 seconds. These features make managing the photovoltaic system easy and straightforward.

Durable Construction and Protection Mechanisms

The controller is housed in a robust metal casing with an IP33 rating, providing protection against dust and water splashing at angles up to 60°. Integrated safety features include protection against overvoltage, overload, short circuits, and overheating. Additionally, the device is certified to international standards such as FCC, CE, RoHS, and others, ensuring its safety and reliability. ### Electrical Parameters
