Size: 400W 12V MPPT KIT
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!

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.

Size: 400W 12V MPPT KIT
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.

Bought two of these, one did not work. The charge controller was defective and would not power up. They would not respond to their phone. I left three messages with no response.
