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

Until I figured out why my WYZE Cameras were turning off at sundown, I was very impressed with this system. I've connected a 12VDC lead acid battery to the controller for storage, and I've plugged the cameras into the two USB ports, not realizing that these turn off at sunset (or rainy day, etc. ). Although the controller has a load output, it is 12VDC from the battery or solar panel. The cams required 5 volts DC. This system would be significantly more valuable if the USB circuits were placed downstream of the battery. To solve the issue, I repurposed a dual USB car charger and connected it to the load terminals, where the cams are now plugged in. It was aggravating because the'manual' made no mention of the USB ports being limited to the solar side of the circuit. I hope this information is useful to you.

This is a fantastic discovery. When I'm out on the water, I use it to charge both my LiFePo4 and SLA batteries, and it works flawlessly. Without it, I won't be able to go boating. Despite the fact that my 30lbs torque motor drains the battery faster than this solar kit can recharge it, it significantly slows the drain, allowing me to double my time in the water. My backup battery is a 20 AH SLA, and my primary battery is an 80 AH LiFePo4.

  So far, everything has gone well. I've finally got some light in the shed without having to spend an arm and a leg. It was very simple to set up. I'm in love with this device because it keeps my battery charged.

I was a little hesitant when I made the purchase, but I was pleasantly surprised when it arrived. The frame and feel of the solar panel are made of solid aluminum. The solar panel's actual material appears to be deep and spotless. I had some panel material that was hazy and shallow, and it did not perform well. Thank the Lord, the charge controller looks and feels better in person than it does in pictures; some charge controllers are garbage from the start. The quality of the cables and connectors is also excellent. Everything connects properly and, more importantly, functions properly. I'm glad I went ahead and bought it. Longevity will be determined with the passage of time.

The battery is dead. I bought two of these to keep two car batteries charged (20 Watt 10 Amp solar controllers).
PROS: I was able to get a reading of 37 Watts (2. 6 amps multiplied by 14 4 volts) when one of these small panels is exposed to direct sunlight. These panels work well with the solar controller, which can safely handle up to a 100 Watt panel. The wire length from the panel (18 inches) to the battery (24 inches) is a good compromise; one of my batteries was at 11 volts, as stated in the review title. 7V, and one of these panels was able to restore the battery to its original 12V. Over a 2-hour period, 5V is applied to the circuit. (To be fair, the battery is already 7 years old and on its way out. ) CONS: br>br> (a) The solar controller's cable screws are small, and it's important not to overtighten them. torque while also being cautious that the cables actually catch and hold tight. (b) The solar controller should be simple to use. settable for the maximum voltage (I chose 13). They continue to charge up to 14 volts at 8 volts. 4 and maintain it. This isn't a big deal for standard car batteries, but it could be a problem if someone uses a more unusual battery. OVERALL EXPERIENCE: br>br>OVERALL EXPERIENCE: br>br>OVERALL EXPERIENCE: b While the Kit is a little pricey for what you get ($50 each), I'm happy with it and recommend it as a way to keep your batteries in good working order.

There are nine batteries and three chargers in my inventory. I figured I'd give solar a shot to see if it had improved in the previous 15 years. So I spent $50 to charge a $25 lawn tractor battery, which usually lasts me two years if I maintain it properly. Last week, the battery started the tractor on the first try, so I knew it was in good shape. This solar device was set up by me. It should be placed in a bright area. Before connecting the batteries, I checked the voltage at the battery connectors. It was 13. Both the display and my multimeter showed 6V. The voltage fell to a low of 12. 4V- When you plug it in, you'll get a voltage of 5 volts. I double-checked the current, and it's currently around. 9A. I assumed everything would be fine. It had been charging for an hour when I noticed that the Sun was obscured by clouds. I went outside to see what was going on. The number four appears on the display. xx V. My multimeter should be brought with me. That's right, it's completely depleted. My Battery MINDer needs to be connected. The battery is dead, according to the message. Now I have to return this trash and go buy a new battery, which I despise doing at the end of the season. It gave me the chance to put my DBPOWER jump starter to the test. On the first try, I was able to get started. At the very least, it worked. It should last me until Spring, and it has come in handy a few times to charge my phone when the power outlet was unavailable. So, for the time being, thumbs down for solar junk and thumbs up for Battery MINDer and DBPOWER jump start.

I have a car that sits most of the time, and the battery would constantly die because it was rarely used. Because my car is parked outside in direct sunlight, I purchased a solar panel kit, hooked it up, and tossed it on the roof rack, and the voltage has never dropped since. It's an excellent option for charging and maintaining 12V batteries.

In my small garage, I connected the kit to a dead truck battery. br>I use it to run an LED strip light 24 hours a day, seven days a week. br>I use a power inverter to power my large-screen TV and laptop. br>Thus far, everything has gone smoothly. So far, I haven't spent much time on the laptop. br>I attached the light to the light terminals that were provided. I use the battery to power the inverter. br>The capacity of a truck battery is 50 - 100 amps. 100 W- Depending on the model and make, this could take several hours. My battery is estimated to be in the 75W range. br>Right now, I'm getting around 4-percentage points. With just 5 hours of direct sunlight, the battery is fully charged and the light is turned on all the time. br>I'm thinking about getting a second unit for my other battery so I can power other lights and devices.
