First attempted was completely cracked. Item need to be shipped with better bubble wrap. Bubble wrap to thin. I did get a refund and order another one and my husband loves it.

Worked well right out of the box. Caution the plug adapter is reversed polarity. The shieled part is negative and the post is positive. Just the opposite of most connections.

I use this to keep the house battery of our 6 horse trailer charged when not in use. It works as promised. The small, simple display assures me it’s operating. I would buy it again

Good

I am very happy with the panels, the products are as described. With long enough wires and good connectors, it’s easy to install and put to work. In the presence of the sun, there is a constant flow of electricity. No doubt this will provide enough electricity for my camping trip and keep my cooler powered.

Will be perfect for Holiday unit to keep stored Suzuki ‘s battery fully charged and prolong its working life

Was gifted 13000 watt generator last year, my wife is so happy. Even though we’ve never had a significant power outage in the 28 years I’ve lived here, I’m obliged to keep my free generator in good condition just in case. First the generator needed a shed to store it in. Then it needed a bunch of very heavy duty cables to connect the generator to the house. Then it needed an electrician to connect the water pump to the generator in a safe way. Next, because we live in Ohio I got a oil core heater so the generator will start when the temperature outside is below freezing.
Finally, I went to start the generator two weeks ago, just because your supposed to run them every now and then and the battery was dead. So I got this nifty solar trickle charger/maintainer. In a few hours (on a cloudy day) the battery was charged enough to start the generator! I still need to pound a T fence post into the ground next to the shed to permanently mount the solar panel.
I’m happy with my investment of this solar panel with control module.

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 Amazon 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. In case the resolution of the photo isn’t good enough to clearly see, the specifications shown on the label are as follows . . .

Portable, lightweight and simple to use.
Works much better than expected.

I purchased this to recharge a battery on a remote water tank pump that I use to irrigate a small food plot. Very Simple setup and charges the battery to 100% by the next day.

Bought 2 of these units for maintaining boat motor battery and trolling motor batteries – works perfectly so far, no over charging issues.
