40A MPPT Solar Controller
40A MPPT Solar Controller
Description:
Description:
Choosing a Y&H MPPT (Maximum Power Point Tracking) solar controller means you will get higher charging efficiency, more stable system performance and longer equipment life. Compared to traditional PWM controllers, MPPT controllers track the maximum power point of the solar panels in real time, increasing charging efficiency by up to 30% or more, making them especially suitable for environments with highly variable lighting conditions.
Specifications:
• Super LCD display screen.
• A full screen view of real-time charging and discharging status.
• Rich load self-management mode.
• Perfect charge and discharge self-protection and self-recovery function.
• Equipped with specific lithium charging profiles, and others.
• Intelligent three-stage charging system.
• USB 5V 2A dual output interface.
• MPPT (Maximum Power Point Tracking) technology with a tracking efficiency of 99.6%.
• Utilizing a 32 – bit chip with a 97% conversion efficiency.
• 12V/24V automatic identification.
• 7days Log query.
