ECO-WORTHY 400 Watt 12 Volt Premium Solar Panel Kit :4pcs 100W Solar Panel+ 40A MPPT Charge Controller+ Bluetooth Module+ Mounting Z Brackets, 400W 12V Solar Power Off Grid System for Home, RV, Boat.

Works exactly as it should! Im getting about 350 watts and 25.5 amps out of the controller at peak sunlight. The key is, at peak sunlight. If your angle is off or there's cloud cover it will drop dramatically, but that's just the nature of solar power. I went a little above and beyond and built a frame that is adjustable to maximize sunlight given the time of year. It helps to have a little electrical knowledge, but if you follow the instructions and know how to use the internet it should be a breeze to install. All hardware and wiring is included. The wiring is just enough to get you going so if you plan on having long runs plan to get some larger gauge wire. The kit came neatly packaged with clear instructions. The controller recognized my lifepo4 batteries and the parameters were good with me so I let it be, however, if youre looking for "out of the box plug and play" this isnt it. You dont have to be an engineer, but its good to have some building and electrical knowledge. I haven't tested the "load" yet, and dont plan on using it, but its charging my batteries just fine and my inverter is working like it should. The app is ok and the BT controller has a decent range. If youre looking for plug and play dont expect that from this kit. If youre ok with getting your hands dirty you'll have no issues getting it set up.

Very well packed. Complete. Good instructions. Seller support. I’m using 8 panels, two controllers, and 4 (12 volt) batteries to run my house during electrical outages. This system will run the furnace and lights along with an electric griddle for cooking. Most importantly keep the refrigerator operating. We are very happy with the kits. It took about a week to complete the project. Mike and Mona

Really impressed with the output and efficiency of the panels and controller. Bought these to upgrade my solar setup from one 100W panel and 100ah of batteries to these with 450ah and the panels and controller and they have definitely exceeded my expectations. In full sun I'm getting over 400W to my batteries . The price is also fantastic, got them on a limited time deal for $330 but even at full price they're completely worth it!

Do yourself a favor and just go to Harbor Freight and buy their 200 watt panels and a separate charge controller. This system DOES NOT WORK. I had to purchase a single 400 panel to get 360 watt charging. This kit only made 35 watts. The panels are horrible. Currently running on the new panel.

I installed this system adding the four pannels with the two I already had. These pannels produced about the same power as the other ones I had, so that was good. The charge controller seemed to get pretty hot, even though I was nowhere near the limits of it. The load function did not work consistently. The Bluetooth module did not come with any useful instructions, so I had to rely on contacting EW through Amazon to get that resolved. There app did not work and had to use a 3rd party one. I did not use the wire, but the brackets worked well.

Its been working very good.. it can recharge a 12v 100 ah battery in 3 hours and keeps its self charged enough to run a a 10.1 cubic foot fridge. Very happy with this purchase.

Ordered this kit for my 27 fifth wheel and it has everything you need to hook it up. I got a disconnect switch and longer wire for the panel to disconnect switch. Shipping was faster than expected. Should have been here on a Friday and I got it Thursday instead. Would purchase again if needed.

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.
