Not very comfortable.

The battery is empty, not charged. The instructions were very difficult to understand. Do you have another brand that would be much easier to use and understand.

Pros
  • Pleasant
Cons
  • Socket required

Definitely not an MPPT

Works, that's all. Not sure what Amazon's policy is for false product advertising, but this is clearly not an MPPT controller! After using it alongside a real MPPT controller and comparing the data, it doesn't come close. Less voltage on panels and less on batteries. I have 8 panels and split them into 4 with this controller and 4 with the slightly more expensive MPPT and was hoping it would be about the same but it wasn't. So I tried to compare it with a cheaper PWM and in fact its specs were…

Pros
  • great product
Cons
  • Good but not great

I'd skip and get something more valuable, like Victron.

a bit disappointed. Currently using this on a 12v system and this controller will not work properly. It's mppt and the controller quickly adjusts the amps. That's the problem. If you use a panel it works fine. As soon as I plug the panel in parallel, the controller can't handle it. Amos actually drops to 0.2 and is not configurable. Since this mppt is actually a slightly higher series voltage, the controller needs to lower the voltage and raise the current. But to my surprise, that doesn't…

Pros
  • nice thing
Cons
  • flimsy

Assembly instructions are useless

Cannot comment on cleanliness or warmth when asked, but solar charging is possible. Put this on a backup power supply I made to power the electronics off a large deep cycle battery. My biggest gripe is with the menus and instructions. Tells you which buttons are which, but doesn't explain what the context menu options are, so try and fail to some extent with all settings. It appears to be solar powered so I think if you don't mind making adjustments this is a cheap option. I would recommend…

Pros
  • Good product for the price
Cons
  • Empty

Works with 30w solar panel and 7ah 12v battery system

1/10/2021 - I bought this and RICH SOLAR 30w 12v monocrystalline PV solar panel ( https://www.amazon.com/gp/product/ B07FN84C9K/) to obtain a charged 12V 7Ah battery and supply power from either of the two USB ports to a Wyze V3 camera to operate, which is mounted in a tree outside the bird feeder; Here's how to make a homemade solar powered bird watching system. My initial system requirements calculations include the following known parameters: The Wyze V3 camera consumes 1,575 watts of power…

Pros
  • Weight
Cons
  • Some small things
