1、CONVENIENT LCD DISPLAY: Backlit LCD displays PV, battery, load charge and discharge parameters. The floating voltage, LVD, LVR, load timer can be adjusted according to the needs of this charge controller. New functions include charging and discharging current, charging and discharging energy recording functions 2、AUTOMATICALLY SHUT DOWN FUNCTION: For acid batteries with multiple duty timers ( OPEN, AGM, GEL). The load should be DC. To protect the life of the battery, once the battery voltage is lower than 8V, the solar controller will automatically shut down 3、PWM CHARGE CONTROLLER PROTECTION: With dual MOSFET reverse current, overheating, undervoltage discharge, short circuit, open circuit, overload, overcharge protection. Safer for home, industrial, commercial and more 4、SMART DUAL USB PORTS: Dual USB port can power two phones, tablets and other devices that need to be charged, maximum 5V 2.5A power supply 5、WIDE APPLICATION: Protected with a coating that minimizes damage from humidity and nesting insects. Suitable for agricultural solar power generation systems, solar street lights, solar garden lights, solar billboards, outdoor camping solar systems, marine solar systems
