<b>❤ IF YOU NEED 20A WATERPROOF SOLAR CHARGE CONTROLLER WITH 24 HOURS LOAD DISCHARGING WORKING MODE, PLS KINDLY SEE ASIN B07CK2PCC7 </b><br><br> <b>■ Safety Instructions: </b><br> A) Make sure your battery has enough voltage for the waterproof solar charge controller to recognize the battery type before first installation,<br> only sufficient battery voltage can charge or activate the controller.<br> That means it won't charge or activate when hooked to a dead or low-voltage battery, or connecting only with solar panel but without battery<br> B) The battery cable should be as short as possible to minimize loss. <br> 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. <br> D) The charge regulator is only suitable for regulating solar panels. Never connect another charging source to the charge regulator. <br><br> <b>■ How to connect solar system with the controller: </b><br> Step 1: Connect the battery to the solar charge controller firstly- plus and minus.(it will auto adapts to the battery voltage) <br> Step 2: Connect the load to the controller secondly. <br> Step 3: Connect the solar panel to the controller finally - plus and minus. <br>♥Note: The reverse order applies when deinstalling. <br><br> <b>■ Specification: </b><br> Color: Black<br> Rated Charging Current:10A<br> Rated Discharging Current:10A<br> Max Solar Input Voltage: ＜50V<br> System Voltage:12V/24V Auto Adapt<br> Self consume: ＜10mA<br> Operating Temperature: -20 ~ +60℃<br> Equalize Charging Voltage:14.4V/28.8V<br> Bulk Charging Voltage:14.2V/28.4V<br> Float Charging:13.8V/27.6V<br> Discharge Stop Voltage:11.2V/22.4V<br> Discharge Reconnect Voltage:12.6V/25.2V<br> Housing: Aluminum Alloy<br> Maximum Wire Size:16AWG<br> Size/Weight: 82x45x21mm/120g<br><br> <b>● Package Include：</b><br> 1 X 10A Waterproof Solar Charge Controller<br> 1 X User Manual<br>
