Review: Very nice setup and with some thought easy to install - I now own two of these and I still can't get the eco-worthy controller to show only LED 1 which indicates a sealed battery. It always shows LED one and two. The directions are confusing or inaccurate. This controller cannot recognize a battery for what it is. Again I have purchased a small MTTP controller that has no trouble whatsoever identifying what my battery is. ___________________ I gave this a five stars because it seemed unfair to ding my review over the fact that the controller that came with it to proved to be unworkable. After 6:00 or 7 readings of the directions I was unable to make the controller recognize and AGM battery. The AGM would go under sealed battery but it kept staying on two lights which meant that it was either a lithium battery or a gel battery. You can't run an AGM battery on anything other than sealed or AGM. For that reason I had to move to a tiny MTTP controller that worked instantly and made it very easy for me to link the battery with the solar panel. I think that it's a very nice system and I'm using it to trickle charge and AGM battery over winter. My plan is to buy another one of these and set it up in the same way to trickle charge over winter a typical sealed battery. Here is something you'll really love. I set this up approximately 24 hours before hurricane Helene hit the mountains of Western North Carolina. The solar panel was set up on a 4x4 post with a 2x4 support that formed a cross. The cord on the panel is very long and makes connection into a outdoor storage cabinet very easy. I then connected some green covered ground wire to a 4 ft piece of rebar next to the 4x4 post. I then stapled the ground wire such that it was not going to pull on the solar panel. The result was very pleasing. It's survived 40 to 60 mile an hour winds. I do hope to figure out why I was unable to program the control panel that came with it.
Review: good value, lot's of watts for the $ - works well, but I wish they put a disconnect near the panel, as the control box is near the charging end. I want to mount the controller near the panel in certain cases. The cord seems heavy duty.

## Questions & Answers

**Q: Does the kit include a manual?**
A: From memory, it was a sheet of paper.  regulator isn't going to last IMHO.  So you should probably look at a backup for that.  Overall we like the product.

**Q: is the panel waterproof?**
A: Yes，the panel is waterproof.

**Q: Can I use this to bring power to a heated pet water bowl? If so, how would you connect it since there is no actual outlet on there?**
A: Hi David, if the heated pet water bowl is DC load, you need one small 12v battery, pls connect the battery, pet water bowl and solar panel to the charge controller, then the kit will bring power to the pet water bowl. If the pet water bowl is AC load, then you need one additional inverter to convert the voltage from 12v to 110v for the pet water bowl. Any further question, pls feel free to contact us AMAZONZYH@163.COM.

**Q: Will this work good for a trolling motor bat.?**
A: My husband says:  Depending on the amps of the battery.  It would not be good for a quick charge, but if you are talking about having a boat in the back yard to connect this to and it would sit for 3 or 4 days at a time it would do the job.  Make sure you get a charge controller as well.

### ⭐⭐⭐⭐⭐ Nice unit, a little pricey, tariffs.
*by R***R on January 18, 2026*

Simple setup. Although not mentioned in the description, the box states 4 amps. That is not correct watts devided by volts is the formula. 24 watts divider by 12 volts is basiclt 2 amps. I knew this in advanced. 2 amps is a decent trickle charge The charge controller protect the battery from over charging.
