Im using this for a trolling mtr, recharge battery as Im fishig. Have not actually put to use yet but have a trip planned in couple of weeks. Will know after that trip. Im running two batteries in parallel. 55 amp hr each. total 110 amp hour. should be able to run all day with no problems. Have several chargers to recharge each battery. I should have enough power for the hole week with recharging capabilities, the solar panel will provide the power to recharge while I'm using power . only able to get 36 LBS thrust from trolling motor, so it does not abuse the battery voltage. I will rate more after my trip, ... show more

  • It really works.
Size: 20W
I have a backyard shed, and I wanted a way to add lights and charge my ATV battery over the winter. So far, it's fall and there is enough light to keep everything charged. The only weird thing is, the polarity out of the controller seems opposite of the standard 12v quick connectors. So please pay close attention to that if you are adding additional extensions or accessories like I did. Anyway, it's a nice small size which was easy to mount and isn't an eyesore. ... show more

  • Trickle charging 3 batteries
Size: 50W
Only had it a week so far but seems to be doing what I wanted. Trickle charging 3 standard batteries on my Motorhome. So far on a sunny days I am showing the 3 batteries at 13.02volts which seems to be what I was looking for. Charge controller is small and very lightweight so I hope it lasts! 1 of the protection corners was broke but don’t seem like it will be an issue. ... show more

  • Great for Maintaining
Size: 20W
I ordered this to keep my batteries topped off on my 5th wheel and it does it perfectly. I run dual led acid batteries and this panel will keep them topped off easily. I do keep the coach turned off so the panel is not charging the batteries under a load. I have noticed if I do leave the battery switch on this panel never seems to reach fully charged but I have not checked the batteries to see the state of charge. This panel is perfect for maintaining the batteries but if you need to do more than that i would get something bigger. ... show more

  • Better quality than others
Size: 20W
I purchased this along with a similar product from another Amazon seller. This one was much better. The included wire was a sufficient gauge on the Voltset. I had to cut the included battery connection wires to put a different connector on it which allowed me to see that the wire was actually a decent gauge wire. Whereas the other brand I bought had just thickened coating on the wire and the copper was a very small gauge. It just looked like a decent gauge. The solar panel is much nicer with protectors over the corners for example. The charge controller was more sturdy and watter resistant as well. Over all I would recommend this one by far over the other brand. Especially since they were the same price. As far as reliability, time will tell. I'll update if I have any reliability issues. ... show more

  • Solar Panel Kit
Size: 20W
The media could not be loaded. The monocrystalline solar panel that is included in this kit is very effective at transforming the sun's rays into useful energy, and it does so with a high degree of accuracy. The power output of 20 W has proven to be more than enough to satisfy my charging requirements while I'm on the road. This solar panel set has proven to be a dependable source of renewable energy for me, whether I'm camping, traveling in a recreational vehicle (RV), going boating, or even using a gate opener. The charging efficiency of the kit as well as its overall performance have both greatly improved as a result of the integration of the MPPT charge controller. This clever controller optimizes the power output, making sure that my electronic gadgets get the most potential charge from the power source. Peace of mind is provided by the controller's built-in protective systems, which safeguard against overcharging, reverse polarity, and short-circuiting. These safeguards protect not only the solar panel but also the electronic equipment I use. The adaptability of this solar panel kit and its user-friendliness makes it stand out from the competition. The adjustable mount bracket enables smooth integration into a variety of surfaces, such as automobiles, recreational vehicles (RVs), boats, motorbikes, and other vehicles. Even if the vehicle experiences jolts or is exposed to severe weather, the solar panel will not be dislodged from its mounting bracket since the bracket is robust and dependable. ... show more
