20A 12V 24V Auto IP68 Waterproof PWM Solar Charge Controller Solar Panel Battery Intelligent Regulator for Solar System Caravan Boat(24 Hours Working Mode)

Safety Instructions: A) Make sure your battery has enough voltage for the waterproof solar charge controller to recognize the battery type before first installation only sufficient battery voltage can charge or activate the controller. That means it won't charge or activate when hooked to a dead or no-voltage battery. B) The battery cable should be as short as possible to minimize loss. C) The regulator is only suitable for lead acid batteries: OPEN,AGM, GEL It is not suited for nickel metal hydride, lithium ions or other batteries. D) The charge regulator is only suitable for regulating solar panels. Never connect another charging source to the charge regulator. How to connect solar system with the controller: Step 1:Connect the battery to the solar charge controller firstly- plus and minus.(it will auto adapts to the battery voltage) Step 2: Connect the load to the controller secondly. Step 3: Connect the solar panel to the controller finally - plus and minus. ♥ Note: The reverse order applies when deinstalling.
