Well built and sealed against the weather with MC4 connector and bypass diode included. Used to power a fan for the attic. The fan is operating even under cloudy conditions. ### ⭐⭐⭐⭐ GET SOME INFO HERE - Fix sharp edges, Install IN a PU truck for use as a maintainer. *by W***S on April 8, 2019* YES, corners are sharp. Here is the PERFECT solution which will prevent scratches on the inside of your windshield. :-)https://www.amazon.com/gp/product/B07J9WRFNZ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1I paid $11.99 You should WAIT 24 hours after installing them BEFORE stressing the adhesive. It needs time to properly create a lasting bond.DO NOT connect this PANEL directly to your car battery. YOU WILL damage your car battery if you do.You NEED a charge controller. Here is a simple and effective one I selected:https://www.amazon.com/gp/product/B073WQC558/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1It was very reasonable at $10.99MOST installations on a vehicle charge batteries that are NOT the batttery the vehicle uses to start and run. THERE ARE some quirks when using on the vehicle's engine/running battery. These are addressed by using easily removed connectors ---> ABSOLUTELY . DO NOT EVER leave the controller connected to your car battery or the panel connected to the controller when not charging. NO, NO, NNNOOOO! To setup for charging, Connect: FIRST connect CONTROLLER TO BATTERY, THEN connect PANEL TO CONTROLLER. TO Disconnect: Remove panel from controller, THEN remove controller from battery. PITA? WHY? VERY sensitive MOSFET transistors are in ALL charge controllers. They can DIE if you forget even ONCE. Also, the electronics can go whack due to voltage imbalances in the circuitry causing a malfunction. Think bootup with bad voltages in your computer. BAD JUJU.-----> From here on, this is NOT for inexperienced technicians.Instead of "Solar" connectors I used EC3 R/C Battery connectors since the panel and controller are IN my vehicle.Get them HERE:https://www.amazon.com/gp/product/B013HSSSAU/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1The MALE CONNECTOR uses 2 FEMALE sockets and the FEMALE connector uses 2 MALE pins. Typically, the MALE CONNECTOR is on the BATTERY side. I HIGHLY recommend you go to youtube and search for EC3 Soldering videos. Doing it wrong WILL be a lesson in frustration... I PROMISE. Doing it RIGHT = easy-breezy pin insertions during assembly. The good news is they can handle 50A!!! I used 14# GPT automotive primary wire. Red / Black. USE GPT it is good to 221 degrees! I COULD have gone with 16# BUT I wanted less voltage drop. ALSO, be sure to use a FUSED tap with the fuse located AT THE BATTERY. I had to do it this way because NONE of my cigarette lighter sockets remain live when the key is not "ON". Even if they were, There is too much potential for a improper connection using cigarette lighter sockets.On the INSIDE of the truck I used a CCTV coaxial jack that I installed on my dashboard. Looks Pro. I installed one of the EC3's on the backside so I could disconnect it from the jack if I ever need to remove the panel the jack is installed into. It goes between the jack and the battery. THIS is it: https://www.amazon.com/gp/product/B07C46XMPT/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1This jack accepts 5.5 x 2.1 mm Coaxial power connectors. Get THOSE here:https://www.amazon.com/DAYKIT-Female-2-1x5-5MM-Adapter-Connector/dp/B01J1WZENK/ref=sr_1_4?keywords=CCTV+Cameras+2.1mm+x+5.5mm+Female+Male+DC+Power+Plug&qid=1554717370&s=electronics&sr=1-4I installed a second EC3 between the SOLAR PANEL and the CONTROLLER for easy system removal when I'm ready to drive.Again, The charge Controller CANNOT remain in-circuit while the truck is running. I disconnect the Panel, then the battery connection as outlined in the instructions for the controller.This is NOT a project for a accountant - You NEED to know what you are doing, otherwise you could cook your vehicle etc. ### ⭐⭐⭐⭐ Excellent solar panel *by A***R on September 28, 2018* Perfect size for a small solar battery charger for camping.
