Features: Adopting advanced MPPT (Maximums Power Point Tracking) technology to improve the charging efficiency of solar panels and optimize energy utilization. Easy installation, terminals design, easy installation, even beginners can easily set up. The battery voltages coverage ranges is wide, and it can perfectly adapt to battery types as low as 12V or as high as 48V. The MPPT controller is equipped with full power input function, providing stable and sufficient power for the equipment, and has obvious advantages in highly power and complex power demand scenarios. The solar voltages regulator has overcharge protections, overcurrent protections, overheat protections, and short circuit protections.
