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

Advanced MPPT solar charge controller with high efficiency for photovoltaic systems.

The EPEVER XTRA3415N G3 solar charge controller represents an efficient solution for energy management in solar systems. It utilizes advanced MPPT technology with maximum power point tracking efficiency ≥ 99.5%, ensuring maximum utilization of solar energy under all lighting conditions. The controller supports automatic battery voltage detection 12 / 24 / 36 / 48 V DC and offers rated charging and discharging current of 30 A.

The device is equipped with an adaptive three-stage charging mode and a special function for lithium battery activation, which protects the battery and extends its lifespan. Thanks to the constant voltage function, the photovoltaic panel can directly power the load even without a connected battery. The controller is compatible with various battery types including lithium, gel, and lead-acid, with automatic temperature compensation for lead-acid batteries.

Advanced features and protection
The controller offers automatic temperature compensation for lead-acid batteries with a compensation coefficient of -3 mV/°C/2V (default value). The device operates reliably in a temperature range of -25 to +45 °C and is equipped with comprehensive electronic protections for safe system operation.

Communication and monitoring
Through the RS-485 communication interface, the controller can be remotely monitored and configured. Support for optional 4G or Wi-Fi modules enables flexible connectivity for remote system monitoring. The LCD display with adjustable backlight duration (default 60 s, range 0 to 999 s, where 0 s means permanently on) provides clear display of operational data.

Applications
The controller is suitable for various applications including recreational vehicles (RV), residential systems, field monitoring, and solar power plants. FCC, IC, ETL, CE, IECS, and RoHS certifications confirm the quality and safety of the product.
