Best something wrong with solar panels

The device seems to be good but the battery in my camper dies after 4-5 days with nothing switched on and working. I'm not sure if the system is bad for this application or if the controller is defective. I just want the battery to charge while the camper is unplugged and it doesn't work for that. I'll try a different controller to see if that's the problem.

Pros
  • Pleasant to use
Cons
  • Actually I don't like it, it's ok

Great combination of solar panel and controller!

This solar panel and controller works great to keep our little waterfall and pond running day and night with a 12 volt pump. I like not having to worry about over-discharging/charging the battery, which allows the pump to run at a constant speed. I will definitely be using this kit again for my future solar projects! 100% satisfied!

Pros
  • Few competitors
Cons
  • Quick Start Guide

Works great - High quality

Everything was high quality and very well packaged. But it requires wiring and assembly. Full assembly is required an hour before use. It worked properly when I first used it. Get a 25ft extension to add to your existing 12ft cord, usually included. The instructions could have been improved but the way things worked out made perfect sense. I used heavy duty industrial velcro to attach the controller to the back of the solar panel.

Pros
  • Handy item
Cons
  • Tape

Good price, no instructions

The most notable thing is that there are no instructions. But the wires are clearly labeled so you know how to connect them. Parts are easy to identify, panel, controller, bracket, cables and hardware. Would it be helpful to have some cable selection instructions if you need to increase the distance between the panel and the battery? Should you position the controller closer or farther from the panel? Does it even matter? Would be helpful and boosts confidence for people unfamiliar with this…

Pros
  • Absolute legend
Cons
  • You could choose a newer model

For my hydroponic garden

I bought this unit and battery to power a 12vdc water pump for my hydroponic garden. This device is well made and the frame is sturdy and will support the panel properly. It comes with all the necessary parts and a nice and strong U-shaped metal bracket to attach the panel to the structure it is mounted on. The mount makes it easy to aim the panel in the best position to catch the sun at my location (and as the seasons change I can easily adjust it). The solar panel controller is mostly made of

  • Easy to use

Works great - generators and portable power supplies

Installed to use as a charger for my motorcycle. Noon at 40Β° N. Sulfate-lead-acid battery. I tried the same thing (with a battery I had stored for several years) and encountered the same symptom: the battery charged for a day and then quickly ran out. This is because there is virtually no capacity left in sulfate batteries. Replacing the battery solved the problem and the new battery doesn't drop below 12.9V (peak charge voltage for a lead acid battery) all night. consumes 22mA. It would still…

Pros
  • Stable test results
Cons
  • Exchange available
