IT-NC G3 Series (50~100A) MPPT Charge Controller with Load Control

The IT-NC G3 Series MPPT Charge Controller is designed for off-grid solar systems that need both efficient solar charging and reliable DC load power. Unlike standard MPPT controllers, this model not only charges batteries efficiently but also directly powers DC loads, making it ideal for applications like solar streetlights, RVs, boats, and remote monitoring systems. With 50A-100A charging capacity, 99.9% MPPT tracking efficiency, and dual PV input options (select models), this controller maximizes solar energy utilization. Some models come with a built-in BLE Bluetooth module, allowing for seamless wireless monitoring via a mobile app. Its intelligent load control supports multiple operation modes, ensuring stable power supply to DC devices. Remote monitoring is effortless via RS485, with optional Bluetooth, WiFi, or 4G modules for real-time data access. Built with a durable metal housing and IP32/IP43 protection, the IT-NC G3 ensures long-lasting performance in various off-grid environments. Whether you need reliable DC power for solar lighting, RV appliances, or industrial equipment, this MPPT controller with load output delivers smart, efficient, and versatile solar power management.
