Tumo-Int 600 Watts Wind Solar Hybrid Charge LED Street Lamp Controller (24V) 600W wind, 300W solar for 24V system Directly light up two pcs 10 Amp DC Lamp Wind turbine brake current:12.5A PWM stepless dumpload mode, which release the excess power into dump load, making the battery charging in best status. Over charge, over discharge, short circuit, lightning, current limiting, brake protection. Wind/Solar hybrid controller is the most important part in off-grid system, whose performance has much effect on life expectancy and operational stability of the whole system, especially the battery expectancy. Or battery service lifewill be shortened by over-charge or over-discharge. Perfect protection function, thus the system has higher reliability. Check and set all operation parametersas requirement from LCD display. Voltage limiting and current-limiting charge mode ensures battery in the best charging status. RS232/RS485/RJ45/GPRS/WIFI/ Bluetooth / Zigbee Rated input power: 600W Protection grade: IP52 Size (wide  high  deep): 150  143  83mm Net weight: 1.8kg Display mode: LCD Conversion efficiency:  95% Display content: Battery Voltage, Fan Voltage, Fan Current, Fan Power, Photo-voltaic Voltage, Photo-voltaic Current, Photo-voltaic Power, Photo-voltaic Turn-on Voltage, Photo-voltaic Turn-off Voltage, Time Control Time, Load Current, etc.
