🌞 Topsolar 20W 12V Monocrystalline Solar Panel Kit with 10A Solar Charge Controller + Extension Cable and Battery Clips O-Ring Terminal for RV, Marine, Boat, and Off-Grid System Review

I was a bit skeptical when I bought it, but was pleasantly surprised when I received it. The solar panel itself has a beautiful, durable aluminum frame and feels nice to the touch. The actual solar panel material looks deep and clean. I had some sheet materials that were blurry and flat and they didn't work well at all. The charge controller looks and feels better live than in the picture, thank goodness. Some charge controllers are junk with Git Go. The cables and connectors are also of linear

I connected the kit to an unused truck battery in my small garage that has no power. I use it to power my LED strip 24/7. I have a large TV and a laptop that I use with an inverter. Has worked well so far. I don't spend much time on my laptop yet. I connected the light to the terminals provided. I operate the inverter directly on the battery. The truck battery is 50-100Wh depending on the model/brand. I rate my battery at around 75Wh. I currently get around 4-5 hours of direct sunlight and it…

Very good value for money. It can be used to charge a 20Ah battery for an amateur radio transceiver. Bought it for a field day to charge the batteries. Works great but only gets 4 stars because the instructions are absolutely sauk, the controller is a little tricky and doesn't support charging and the wire gauge between the controller and the battery is incorrect and this kit doesn't have proper fuses. I strongly recommend changing the wires. ***Update*** I used the USB port to charge an old…

I was very impressed with this system UNTIL I found out why my WYZE cameras were shutting down at sunset. I have a 12VDC lead-acid battery connected to the controller for storage and the cameras are connected to two USB ports, unaware that they will be at sunset (or on a rainy day etc.) ) switch off. The controller has a load output, but that line is 12V DC from the battery/solar panel. I need 5VDC for the cams. A simple design change that allows the USB circuitry to be placed under the battery

I have nine batteries and three chargers. I decided to try something solar powered just to see if it got any better in the last 15 years. So I spent $50 to charge a $25 lawnmower battery that would normally last two years with minimal effort to keep it in decent condition. The battery started the tractor on the first try last week so I knew everything was fine. I connected this solar light. Put in a sunny place. Checking the voltage at the battery terminals before connecting showed 13.6V, both…

I bought 2 of these to service two car batteries (20 watt + 10 amp solar controller). PROS: Measured up to 37 watts (2.6 amps x 14.4 volts) in direct sunlight from one of these small panels. The solar controller works great with these panels and can safely work with up to 100w panel. The cable length from the panel (18 inches) to the battery (24 inches) is a good compromise. As stated in the title of the review, one of my batteries was 11.7v and one of these panels was able to get the battery…

20 watt kit is great. Includes everything you need to use the stock RV battery maintenance kit. The battery on our caravan trailer is very old and I thought it needed replacing as it is struggling to reach a full charge after being stored in the warehouse for a while. However, after being connected for a few days, this solar panel and charge controller seems to have saved our old battery from the abyss! The full charge of the battery is achieved by solar energy, while a standard charger cannot…
