Product description: Easy to use: This product is a semi-flexible board that can be bent up to 30 degrees. It is suitable for mounted on an irregular smooth surfaces such as RV roofs, boats, tents, Yacht, vaulted roofs, etc. High efficiency, Light weight: only 3mm thick, weight 2.2kg, easy to hang, disassemble and carry. Easy to install: Metal holes in the four corners of the product for fixing screws and mounting. Each solar panel has been tested several times. The junction box on the back of the solar panel has a Schottky diode built in to prevent reverse current. The solar panel operates at 18V. Please purchase a solar controller to charge the battery. Controller: Model: PWM Buck charge: 28.8V Float charge: 27.4V USB output: 5V/3A Self-consume: <10mA Discharge stop: 21.4V Voltage: DC 12V/24V Max solar input: <50V Current: 20A/30A Rated working current: ≤20A Discharge reconnect: 25.2V Working temperature: -35℃~60℃ Output voltage: 12V/24V Automatically distinguish voltage 　 Safety Instructions: 1.Make sure your battery has enough voltage for the controller to recognize the battery type before first installation. 2.The battery cable should be as short as possible to minimize loss. 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). 4.The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator. 　 　 System Connection: 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. 2.Connect the photovoltaic module to the regulator - plus and minus. 3. Connect the consumer to the charge regulator - plus and minus. Note: Please allow 0-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
