40A MPPT Solar Charge Controller for 12V/24V Solar Panels Temp Sensor LiFePO4 Batteries

Core Features

Advanced MPPT Design for Maximum Efficiency

Thanks to the innovative Max Power Point Tracking (MPPT) Technology, the LNEX MPPT solar charge controller boasts a high tracking efficiency of up to 99.5% and a peak conversion efficiency of 98%. This advanced design improves the utilization rate of your solar panel system by approximately 20%-30% compared to regular Pulse Width Modulation (PWM) controllers. Even in cloudy conditions, the LNEX MPPT controller ensures maximized solar panel production.

12V/24V Automatically Detect

Our LNEX MPPT solar charge controller automatically detects 12V or 24V DC system voltages and clearly displays solar charging, battery operation information, customizable parameters, and error codes via its LCD screen and multiple LED indicators. It is compatible with various types of batteries, including LifePo4, LTO, GEL, AGM, Lead-Acid, and Calcium, making it suitable for deep cycle, starter, marine, car, RV, powersport, and more applications.

5-Stage Safe Charging

With 5-stage charging (Soft Start, Bulk, Absorption, Equalization, and Float), the LNEX MPPT solar controller increases battery life and enhances system performance. For Lithium batteries, it uses a 4-stage charging (Bulk and Absorption) and includes Lithium Reactivation as well.

Full System Protection

The LNEX MPPT solar charge controller is equipped with over temperature protection, over voltage protection, over current protection, over charging protection, over discharging protection, over load protection, and short circuit protection. This comprehensive protection maximizes safety and minimizes damage due to system faults or installation errors.

Temperature Sensor Port

Equipped with a Temperature Sensor Port, the MPPT solar controller can measure battery temperature in real-time for accurate temperature compensation, ensuring stable and constant charging. Note that the temperature sensor is sold separately.

User-Friendly Design

Our LNEX MPPT solar charge controller is designed for ease of use, featuring straightforward settings and allowing you to customize the voltage if needed.
