For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically (LCD will be unavailable at the same time).<br> <br><b>Easy to operate and installation :</b> <br>Wiring STEPS: Screw the adjustment screw counter-clockwise until the plates move down. Insert the wire into the new opening between the plate and the "top" of the Terminal hole, not under it. Screw the adjuster clockwise and the plate will move upwards thereby squishing the wire in the Terminal hole. <br>Installation STEPS：Connect the system in the order of 1.Battery > 2. Load > 3.PV Array in accordance with Figure, and disconnect the system in the reverse order 3. 2 .1.<br> <br><b>Note:</b> <br><1>Please keep it in cool and well ventilated place to maintain good heat dissipation. <br><2>the regulator is only suitable for lead acid batteries:OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries. <br><3>Make sure your battery has enough voltage for the controller to recognize the battery before first installation. <br><4>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.
