Specification: Item Type: Solar Charge Controller Material: Aluminum Alloy, PC Weight: Approx. 1185g/41.8oz Size: Approx. 230x165x66mm/9.1x6.5x2.6in System Voltage: 12V 24V 36V 48V PV Input Voltage Range: 15V to 23V (12V) /30V to 46V (24V) /45V to 69V (36V) /60V to 92V (48V) Charging Mode: PWM Product Introduction 1. The use of industrial design of heat dissipation structure, flame retardant material shell, four button operation. 2. Using high efficiency, excellent quality, low internal resistance of large package MOS tube drive, stable performance. 3. The battery "over discharge, over voltage, under voltage" protection. 4. The load discharge current is protected by overload. 5. Photovoltaic panel current "overcharge" protection. 6. There is the machine temperature "overheating" protection. 7. There are positive and negative electrode "reverse connection" protection. 8. Load output short circuit protection. 9. Used in "colloidwater battery or lithium iron phosphate or lithium ion battery". 10. Charge and discharge control parameters can be manually adjusted. 11. Use the original imported chip control. 12. Equipped with two independent USB interface circuits (total 5V 2A constant current, short circuit protection). 13. LCD display with backlight function. 14. Automatic identification of 12V 24V 36V 48V battery in all stages. 15. Automatic "default" and manual setting of lithium battery in all stages. 16, when the battery voltage is "0", the photovoltaic panel can be started. 17. The load is normally on (the load is steady on). 18. Pure light control mode (load during the day, the day is dark and bright). 19. Time controlled mode (manually set load on time and load off time). 20. Light control and time delay (when light control is on, you can set the length of light on time). 21. Enable the function of random load. 22. Clock function (power off invalid). 23. Charge and discharge amount accumulated. 24. Has the function of restoring factory settings. . Package List: 1 x Solar Charge Controller1 x English Specification Note: 1. Prepare relevant tools and select premium cables with a current density of 26A/mm2.2. The controller will generate heat when working. Please install it in a well ventilated environment.3. Connect all battery cables before connecting other cables.4. Can not connect to the controller of the rated charging current of the photovoltaic panel.5. Do not connect the load with the rated discharge current of the supercontroller.6. Do not use any switching power supply (such as AC to DC power supply and DC to DC power supply) to connect to the controller instead of the photovoltaic panel.7. The disassembly sequence of the line is opposite to the wiring sequence.8. The work of the photovoltaic panel must be 1.5 times the voltage of the battery grade.
