Solar Charge Controller 50A,Solar Panel Charge Controller 12V 24V, Intelligent Regulator with Dual USB Port PWM Auto Paremeter Adjustable LCD Display

Features (1)Automatically manage the working of solar panels and batteries in the solar system. (2)Dual USB output,the maximum current of 2.5A,to support mobile phone charging. (3)Build-in short-circuits protection,open-circuit protection,reverse protection,over-load protection. (4)Dual MOSFET reverse current,protection from a lightning strike. (5)Prolong the battery life cycle and keep the load work well. (6)Easy to set up and operate. (7)Suitable for the small solar energy systems. Common Q&A Q: How to install it? A: (1)Battery --->(2)DC load ---> (3)Solar panels Q: Why the LCD screen becomes blank? A: When the battery voltage is too low,the controller will stop to output(? 8V,controller turns itself off, LCD is blank, ? 10.7V,12V output ports are not available); after the solar panels charging,it will re-output when the battery will return to 12.6V. Q: What battery type is this controller supported? A: The regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries. Product Specification *Rated Voltage: 12V/24V *Discharge current: 10MA *Max. PV Voltage: 50V *Max input power and voltage: 260W /12V; 520W/24V *Floating charge: 13.7V/27.4V  *Discharge Stop: 10.7V/21.4V  *Charge recover voltage: 12.6V/25.2V  *Working Temperature: -35 to 60 degree Celsius *Load Mode: 24 hours,1-23 hours,0 hour Note Old batteries may be degraded the capacity after hundereds of cycles, easily drop lower than 8V, which results in the controller will be shut off (LCD screen become totally “DEAD”). Connect the inverter (DC / AC) to the battery. DO NOT connect to the solar controller. Package List 1XSolar Charge Controller 1XUser Manual
