Bought it for my husband's garage. He set it up, it seems to be working, so yeah, good purchase!

Good deal working in Cuba

Everything has worked well all winter long except for the Bluetooth app that never would sync up

Well packaged. They seem to produce a lot of power, even on cloudy days. My battery is always full, so far. I wired them in series. Have not tried the Bluetooth thing yet, but the controller works well. They sent cables way too thin to run from that to the battery, though. Had to buy a thicker gauge. It would be nice if this kit came with the necessary fuses, but all-in I’m happy with the purchase and would buy this brand again.

Everything was packaged very well. All contents look to be well built. The controller didn’t work. However, so far Eco Worthy has been very accommodating with sending a new controller. I haven’t received it yet though. Keeping my fingers crossed.

Package arrived safe and sound with no damage. I haven’t tested it yet, but I’ll update this review when I do. Very excited!!

Do not buy this thing. Try another brand. First, p*i*s*s poor instructions. They tell you to get an electrician and damn little after that. I could not find one in my small town that would do solar. I had to watch about six Youtube videos, call the company itself, and still was winging it. Second, whoever designed the charge controller learned their trade back when Einstein filed his first patent BC the freaking connections for ALL your wiring are so screwed up I almost quit. I had to buy a whole new set of wires, crimping plyers, and two different sets of hollow copper casings just to get the wires to fit in securely. Did I mention the instructions SUCK?

I installed my 400-watt solar kit in mid-January. The support team was very responsive and helped to solve details I had with the controller. It works well. Thank you, Eco-Worthy. Value for the money.
