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 3This amount that controller on the wall mount your solar panel outside in a nice sunny w area and the rest will do its job!

The media could not be loaded. 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.

good product

For the price this is great. Keeps my outdoor shower pump battery charged.

Complete system for small project I am using it in a storage shed for lighting and even going to put a small converter on it

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.

This was a very easy installation and setup. Connected the controller to the battery and then connected the solar panel and charging began! Once that was going on fine tuning the settings for max charge voltage and max discharge level were easy to select.I would highly recommend this purchase to anyone looking for a plug and play solar setup.

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 radiobatteries, 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.
