1,PREMIUM CONVERSION RATE: Using high frequency switching for MOSFETs with extremely low conduction resistance to replace traditional rectifier diodes greatly improves converter efficiency, reduces the overall housing temperature, and achieves a minimum housing for greater power output. 2,ONE BUTTON RESET: When the system encounters an abnormality, one button can reset and restart, making the operation simple. 3,WIDE APPLICATION: The controller outputs multiple voltage ranges and is widely used in various solar electric vehicles. 4,STAINLESS STEEL MATERIAL: Made of premium stainless steel material, the boost controller is rust and corrosion resistant, ensures a long service life. 5,EASY INSTALLATION: Comes with a small and compact size, and light weight, the solar boost controller can be quickly installed and put into use. Item Type: Solar Boost Controller Material: Stainless Steel 1 x Solar Boost Controller 2 x Fuse Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
