UEIUA Solar Charge Controller 12V24V 30A PWM Solar Charge Controller Auto Switch LCD Display Solar Panel Regulator with Dual USB

?Specification: ?Voltage: DC 12V/24V ?Self-consuming: 10MA ?Rated Charge Current: 30A ?Rated Load Current: 30A ?Over charge Protection: 14.4V/28.8V ?Over charge Floating charge: 13.7V/27.4V ?Charge recover voltage: 12.6V/25.2V ?Over discharge Protection: 10.7V/21.4V ?Over discharge Recover: 12.6V/25.2V ?USB output: 5V/3A ?Operating temperature: -35?-60? ?Size:150 * 78 * 35mm / 5.9 * 3 * 1.4in ?Warmly Tips <1>Please keep it in cool and well ventilated place to maintain good heat dissipation. <2>the regulator is only suitable for lead acid batteries:OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries. <3>Make sure your battery has enough voltage for the controller to recognize the battery before first installation. <4>Indoor use only: the working temperature of this controller is -35°C to +60°C, during hot sunny days, the temperature outside might go up to 60-75°C. Please do keep the controller stay in cool and well-ventilated place to maintain good heat dissipation. <5>When the battery voltage is too low, the controller will stop to output(? 8V, controller turn off itself, LCD is blank,? 10.7V, 12Voutput ports are not available); after the solar panels charging, the battery will return to 12.6 V. It is a natural to output. ?Advantage (1)Automatically manage the working of solar panel and battery in solar system. (2)Overloading and short-circuit protection. (3)Build-in short-circuit protection, open-circuit protection, reverse protection, over-load protection. (4)Protection from lightning strike. (5)Prolong the battery life cycle and keep the load work well. (6)Easy to set up and operate. (7)Suitable for small solar energy system.
