1. Introducció
The EPever XTRA N series solar charge controller utilizes an advanced Maximum Power Point Tracking (MPPT) control algorithm to efficiently manage power from your solar array. This technology minimizes power loss and quickly tracks the maximum power point (MPP) of the PV array, ensuring optimal energy harvesting under various conditions. Compared to traditional PWM charging methods, the XTRA N series can increase the energy utilization ratio in a solar system by 20%-30%.
Key features include limiting charging power and current, and reducing charging power functions to maintain system stability, especially in high-temperature environments. With an IP33 ingress protection rating and an isolated RS485 design, the controller offers enhanced reliability and versatility for diverse applications. The self-adaptive three-stage charging mode, based on a digital control circuit, effectively prolongs battery lifespan and significantly improves overall system performance. Comprehensive electronic protections against overcharge, over-discharge, and PV & battery reverse polarity ensure a reliable and durable solar system. This controller is suitable for RVs, household systems, field monitoring, and other similar applications.
