Added this fan when the when the smaller (4") red fan was not enough. Install was easy, the nylon wall anchors made usable nuts for the provided screws when mounted to the greenhouse panels. I added some supports to the solar panel bracket so I could mount it on the greenhouse apex and have east/west tilt adjustability. The louvers are nice, they give you a quick visual that the fan is running, There is also a grill on the other side. The fan moves a decent amount of air, even in bright overcast skies. It is relatively quiet, you hear the air motion.
I wasn't sure how good this was going to work, especially on days that we don't get a lot of sun because it being winter and cloudy. However, the one thing I wasn't expecting was it to work just as good as it does when its bright and sunny on days that it's not so bright and sunny. I bought this to replace my old solar panel on my feeder and not only does it work but it works way better than the old one that I had. Plus I found that when I do clean this, that its so much easier to clean and doesn't streak easily at all. Not to mention, there is an area in the back that will show me that its on but also how much power this panel has left.
Wanted to have my observatory completely off grid, buying and installing 2 of them has provided more than enough energy. The size was perfect for the tops of the bays where I added them.
First off, I never intended to use just one of these panels to charge my 12V lead acid car battery with the included PWM charge controller and attached wiring harness. Rather, I intend to buy multiple examples of these panels and configure them with a more comprehensive MPPT controller, LiFePO4 battery and inverter in a carry-in-car and set-up-quickly portable application. The 23.1" (541mm) square footprint is ideal for the portability I need and the price is certainly right. Fortunately, the fit and finish of the panel itself is very good. This sort of thing would have easily cost twice as much just a few short years ago. There are a few rough edges on the corners of the aluminum framing, but that's a minor point. The individual cells look to be very cleanly assembled, topped with a nice piece of glass and the caulking sealant job along the interior of the frame is very clean. I knew from the tugapower.net listing, however, that the panel would come with a 6' long piece of spindly zip cord terminated with a 2-pin trailer connector. The good news is that the junction box termination on the back of the panel is of the conventional type with a water-proof seal. It's going to be relatively easy to solder in better cabling with standard MC-4 connectors. As it turns out, the attached cable (basically 14 gauge red/black lamp cord) had a short . . . zero voltage and amp readings on the multimeter at the connector end! Readings off the tabs inside the junction box (easy to pry off the back cover with a flat blade screwdriver) indicates, though, that the panel outputs 23.6V and 2.5A on my quickly-assembled back yard test rig (picture attached.) That's very good. I tested at Noon with reasonably perpendicular panel/Sun angling on a cloudless day. Ambient temperature was approximately 70° F / 21° C Next, I trimmed/stripped the 14 gauge wires to within about 1 foot of the junction box and got similarly good readings. Subsequently, I found out that the short was in the remaining (now detached) ~5 feet of cable somewhere along the black/negative wire. I did not test the included PWM charge controller. If it was just for the panel itself, I'd give the Solperk SK-M50W a solid 5 stars. I'm knocking it down to 4 stars because the wiring harness is terrible and, in my case, non-functioning out of the box. I will be buying more of these panels for my above-described application, knowing that the other included bits will be going into the waste can and I'll need to solder in suitable 10 gauge wires at the junction box end, terminated at the other end with real MC-4 connectors. The additional attached photo here shows the back of the panel (junction box cover removed) with labeling.

If you want a 3000 Watt pure sine wave inverter that is built really nice, then this is it! First off I like how the inverter is mounted because it doesn't just mount flat against the surface it is raised up by about a 1/2 inch so air can get to the bottom of the unit and help keep it running cooler! Plus it has 2 internal cooling fans and they are strong and they turn fast. So with that being said this inverter gets warm but has never gotten hot in my months of use. The 2 sets of 5 AWG copper cables that come with this inverter are good quality as well and are actually copper instead of copper clad aluminum like you'll get with other Inverters. But if you are going to run this inverter at above 2000 watts i would upgrade the cables to a 1/0 knuconceptz cable! The customer service is great, just email them and they will always message you back. The inverter has all the safety features in place to protect your devices from damage. The over voltage protection, over temperature protection and overload protection are all great features to have. Plus this inverter is backed by a 1 yr warranty. Hopefully this review helps you out!
Easy to cover and remove
Cables are a little stiff, and seen made of aluminum, not copper. But the plugs fit together ok and are well secured. They passed the pull test and indicates a good solid crimp inside the plugs. 6'6" is accurate in fact mine were just a bit longer
I used this solar panel with a Meidase P70 trail cam and it works great. The solar panel recommends having batteries in your trail cam for backup, but it charged pretty quickly so I will likely not do that depending where I place the panel in the field. The power cord comes with a usb-c to barrel plug wire with an adapter to a different size barrel plug. I do wish the angles for mounting were adjustable, but this is not that big of a deal and this solar panel is a great option!
Funciona a la perfección 1 panel de 600 wats Conseguí 550w real 👍🏻a 12volts
Knock outs were just stamped. Had to use a drill for the knock outs since they wouldn’t punch out. The bottom came off and had to weld back in place. Disappointed
The ELEJOY 1800W Solar Panel Tester MPPT works exactly as expected! It's an excellent tool—smart, portable, and reliable. I found it to be well-designed and efficient, making it a valuable tool to help set up a solar system. Highly recommended!
One of the best solar panels for all types of batteries, they really make your life easier and the quality of the product is one of the best, I really recommend it, and its product installation is really easy since its manual is well explained.
This review is for the MOOKEERF brand MC4 to female XT60, 30 foot, 10 AWG extension cable. I have reviewed many products from MOOKEERF, and I can’t think of a single one that was not good quality. This cable is no exception. It is made from 10 gauge 2 conductor wire with a heavy sleeve protecting the wire. One thing to note is the sleeve has a tacky feel. All similar product use the same sleeve, but it has a tacky feel and is a dust and dirt magnet. Keep that in mind before you order.
It’s a very nice box, all metal seems to be .049” thick, it’s smooth with no sharp edges, and the paint is good everywhere. There is plenty of room for making connections, it's a little large, but it does make hook up much easier. The knockouts for wiring are quite good, one on each side towards top, two on the bottom, and none on the back. The instructions are just as good as needed and if you’ve done wiring before it should not be hard to figure out. The plug looks to be very nicely made and works well also.
