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

This solar controller with solar panel works amazing it helps me out of a tough situation when my power went out and to help cut down on my electric bill in the lighting in my bedroom. This solar controller helped keep my battery is fully charged and maintained while regulating the electricity to my electronics! The insulation is very easy just need a small Phillips head screwdriver a spot to mount it and a battery connect to the ease of installation is as easy as 1 2 3 This amount that controller on the wall mount your solar panel outside in a nice sunny w area and the rest will do its job!

During my initial testing outside I couldn't get any output on the "load" connection. However, I must have been doing something wrong because today everything is working fine. I got a normal voltage and current output on both USB ports, a good charge voltage for the battery and over 10 volts/ 6 amps on the load. It should work fine on my e-bike for supplemental USB power and maintaining a12v battery for other peripherals.

Works well keeps my battery happy

Great light weight design, perfect for battery maintenance or any other power needs!

It kept my two marine batteries charged up for four months..

I have this panel hung in the window inside my enclosed porch connected to an old truck lead acid battery. I use it to charge AA, AAA batteries, Headphones, (3) 26800 mAh battery packs, vape pens, Baofeng radio batteries, truck jump start kits, headlamps, flashlights, bicycle flashing lights, etc. Ive been doing this for well over a year and I've had no problems at all. I would recommend this item.

The following is in my opinion based on my past experience only: I am having problems getting it to keep my settings and so I am just glad the lifepo4 has controller for protecting the lifepo4 🤔 The USB work only when the Sun is shining and when the sun is not shining only provide less than 5 volts each. Further if u use the 2 USB ports the unit becomes hot to the touch while another Amazon 2 USB to battery terminals stays normal and no heat created while connected to 2 USB outdoor cameras. Further it's nice to see the battery voltage displayed the unit. Update Aug 1 2024🫤 In my opinion based on my past experience only I am confirming the unit doesn't heat up if the 2 attached USB ports r not used, so I guess these ports r for temporary use during the daytime. Further on the issue of manual setting the numbers for voltage as an example; going from 28 volts toward 13.9 volts; ar 26 volts the next number is 29 volts. It appears this unit is for lifepo4 batteries connected is my guess only.

I have owned this kit for almost two years now and it has been great! I purchased it for my camping set up in my vehicle and it hasn't let me down. This was my first time messing with Solar Panels and really anything electrical. It is pretty straight forward as far as installation goes. You can't really mess it up. The panel delivers the wattage as advertised and the charge controller is optimal. All in all, a good way to get your feet wet in the Solar world!
