Works like it should and met expectations

Works like it should and met expectations
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.

    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.

    I had no power in my shed, so I bought this kit hoping it would be a good workaround, and it ended up solving the problem for me. It was a lot easier than trying to run power out there, and now I have a much more usable space.

    What I liked most was that it gave me a complete setup instead of having to buy everything one piece at a time. Once I got it going, it did exactly what I needed it to do.

    Overall, I’m really happy with it. For anyone trying to get power to a shed or small building without running electric, this turned out to be a great solution.

    Looks like I got the defective one. The controller will not charge. All parameters are within range and all start up procedures were followed properly but still no charge current. Internal fuses are still intact. The wire terminals are a good design but poor materials are used. The PV+ terminal broke due to low quality material. I had to find an alternate solution to connect to terminal which is more than a pain in the neck. The controller has a nice look to it but it’s worthless as of now. Customer support has not picked up the phone or returned my phone call. If you are new to solar and are buying this kit I recommend you just do your homework and build a system piece by piece with quality products. I have used ecoworthy panels in the past and they work but like the controller the panels are made of low quality thin aluminum. Please save yourself the time and headache and build a system on your own. Go with Outback or midnight solar for your charge controller. This kit is a waste of time and will only cause you to regret your purchase later. Do it right, do it yourself.
