Description
The ET-NC G3 series is a new generation of high-current MPPT charge controller. It offers 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.
