The IT-NC G3 series is a new generation of high-current MPPT charge and discharge controller. It features load output capability and delivers superior MPPT tracking and conversion efficiency. The series is compatible with various lithium battery types and supports three-stage charging management to extend battery lifespan. Its exceptional low-power design significantly reduces static consumption, prolonging system standby time. Comprehensive electronic protection and flexible communication options (WiFi, Bluetooth, 4G, etc.) further enhance system reliability and monitoring capabilities. It is widely used in RVs, boats, industrial monitoring, and small to medium-sized solar power systems.

**PLEASE NOTE: This unit has an internal relay which sometimes clicks on and off early morning and late evening, when the sun is not quite strong enough to run the MPPT, but there is some ambient light. Therefore it is not recommended to install this unit in a location where the sound could cause a disturbance.**
