1,Rated Discharge Current: 20A; USB Output Voltage: 5V/3A; Battery Voltage: 12V/24V auto. Adjustable power rate with dual USB ports; 4-Stage(EQU, Bulk, ABS, Float) charge management and 4-Stage PWM charge<br>2,Funtionality: Equipped with industrial-grade STM 8 microprocessor to control the charger and discharge process and it has reliable battery to charge and discharge period management<br>3,Mutiple electric protection: over-current and short-circuit protection, inverse connection protection, low voltage and overcharge protection<br>4,Good Heat Dissipation: Dual mosfet reverse current protection, low heat production<br>5,Easy to use: Comes with a display that can clearly indicate the status and data, it can be conveniently switched modes and parameter configuration, suitable for home, industrial, commercial etc <br><br>Specifications:<br>Rated Voltage: 12V 24V Auto<br>Application: Solar System Controller<br>Current: 10A, 20A, 30A<br><br>With Timer and light sensor,it could work for solar light system.<br>Only For off-Grid PV Solar System.<br>For 10A 12V Pv System: 120W Solar Panel,12V Lead-acid Battery,21V for Max input Voltage<br>For 10A 24V Pv System: 240W Solar Panel,24V Lead-acid Battery,42V for Max input Voltage<br><br>&gt;&gt; SAFETY INSTRUCTIONS<br>1.Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.<br>2.The battery cable should be as short as possible to minimize loss.<br>3.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>4.The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.<br><br>&gt;&gt; SYSTEM CONNECTION<br>1.Connect the battery to the charge regulator - plus and minus.it will show 1, if it detects 12V battery, 2, if it detects 24V battery.<br>2.Connect the photovoltaic module to the regulator - plus and minus.<br>3. Connect the consumer to the charge regulator - plus and minus.<br>The reverse order applies when deinstalling!<br>An improper sequence order can damage the controller! <br><br>Package include:<br>1 * Solar Charge Controller <br>1 * Users Manual
