Ass a reasonably compact solar panel kit goes, this one is decent but there are a few things to watch out for. The panel itself is a pretty standard basic monocrystalline panel measuring a little over a foot by a foot, so its nice and compact. It’s rated maximum output is 50W, so this isn’t really suitable for rapidly charging a battery, but more appropriate for topping up and maintaining a battery that goes a while between uses.
The kit includes the panel, pre-wired, a charger controller, and a set of O-ring and alligator clip connectors. What it doesn’t include is a set of MC4 copper connectors, which the instruction booklet does take some pains to say should be placed between the bare panel wires and the controller. That’s disappointing that the kit wouldn’t include such a basic part, but it is readily possible to wire the panel directly to the controller without them, you just lose the quick-connect functionality and additional length.
The controller is just as important as the panel, and this one is decent with several adjustable functions, but the documentation is truly, awfully, abysmally bad. Unless you have experience with these controllers – I didn’t with this type – be prepared to spend some time on Google and Youtube looking for help. One caution – while it has presets for various battery types, the preset on the lead-acid batteries is for a standard vehicle battery with a max charge set at 14.4V. A marine deep-cycle battery float (at least according to my research on this) for a boat or RV sits at a lower voltage of around 13.7V, and a higher setting will kill the battery; it’s not obvious if the three settings are max, float, and cutoff from the documentation. Lesson here is pay careful attention to programming the right settings or you can destroy your battery over time. The other drawback on the controller is it displays only volts, not amps, so you can’t tell what wattage the panel system is actually outputting.
The alligator clips are fairly good and connected easily to my battery, while the O-rings are too small for the terminals on my relatively small deep-cycle 12V marine battery. The controller is designed to be wired between the panel, battery, and load, so if your battery is normally sending out to the load itself you’ll need to change that.
One good but somewhat disappointing feature is the controller has two USB ports for direct charging, but the controller will only power on its display if connected to a battery – the controller isn’t made to transfer power direct from the panel to the controller. It will, however, route power to the USB-ports and charge a connected device without a battery hooked up, though you cannot tell the voltage being sent.
At time of review, this kit is $76 CAD. It’s not bad, but the lack of the recommended connectors and poor documentation is frustrating.

A pretty complete solar charging panel for low dollars.
Although the instructions are a little bit lacking, the system and wiring are pretty easy to figure out, as is the charge controller.
The panel is well-made for a cheaper panel and delivers substantial output. I just use this to maintain my camper’s batteries between charges, so not a demanding situation in my case. The controller is pretty easy to set up.
Overall, for the money, this is a good kit.

This is a basic but decent solar charging kit. The solar panel itself lacks a bracket, or any sort of mounting hardware, and the cord is very short and ends not in any kind of connector, just a naked wire to be added to the charge controller or spliced into your connector type of choice manually. The output is genuine, at peak sun I tested it at 2.50 amps and 23.5 volts direct from the panel, which given amps x volts = watts comes to 58.75 watts, even better than rated. It’s a great sturdy solar panel itself, but with the short cord, no mounting hardware, and no connector, it’s hardly complete alone.
The charge controller is PWM, not the more efficient MPPT type, but it works well. It’s the kind where you need to use a screwdriver to loosen its “teeth”, feed the wire ends into the appropriate holes, and tighten the screws to lock them down again. It works, and you have the option of clamps or O-ring connectors for the battery connection, but it is, again, not ready out of the box. It supports the common battery types, and you can adjust voltage levels for cutoff and such by using the menu button and arrow buttons. Again, more work manually fiddling around to get it set up where you want it. The LCD display shows the current battery voltage and charging status, it is helpful, but dim, with no backlight, and hard to read under full sun or deep shadow.
The charge controller also has a hookup for a DC load, be it a small fan or, as I used, a 12-volt light bulb, so that the controller has somewhere to dump current when the battery is full. You can set the time in hours that is allowed to run in the charge controller’s settings as well. Like most of this kit, they don’t give you that part, and it requires at least some familiarity with solar equipment not found in the manual.
As a solar hobbyist who has used all of these parts before and rigged up my own cables dozens of times, I found this kit a very nice set of pieces to work with, but it definitely feels less than complete, nor is it ideal for beginners. I was happy with the parts I got, and their quality as a whole, but for a total solar beginner just looking to charge a battery I’d get something more ready-made, with a panel bracket or mount, quick connect cables, and a two-wire charge controller with no DC load feature.

This is an awesome kit that comes with almost everything you need to set up solar power solution. I connected this to a lifepo4 battery and use it to keep the battery topped off.

This kit consists of a 50 W solar panel and a 10 Amp PWM charge controller. All wires are bare ended, so unless you connect them directly to the controller, you will have to add your own connectors. The controller is very basic, and the instructions are not clear at all. I have several controllers, both MPPT and PWM, and this one was the hardest of all to set up. Those who are new to solar systems will likely have trouble with this kit. I charged four different small (7 – 15 Ah) LiFePO4 batteries, and the BMS in one of them apparently activated its over-voltage protection, resulting in a continuous disconnect and reconnect loop. The other three had no problem.
I monitored the panel’s output to the controller with a DC clamp ammeter and voltmeter while charging the batteries, and it delivered 13.5 volts at 2.5 Amps, or about 33.75 Watts. This is about what I expected from a very hot panel under the sub-tropical sun. You may get more output in cooler temperatures, but no panel will deliver the full rated output except under controlled laboratory conditions.
The weak point of this kit is the controller, and the lack of clear instructions make it a poor choice for first-time users.

Update 8/27/24: The solar panel does not perform well in shady conditions, often producing no usable power. Another reviewer reported that the panel produced 58.75W. That was a mistake, because he used VOC (Open circuit voltage) in his calculation. He used 23.5 V multiplied by probably short circuit current 2.5A. As soon as there is any load, the voltage will drop significantly. Even the specs claim Max Operation Voltage only at 18V. How we wish these cheap Chinese solar panels can produce 17.5% more power than claimed.
Update 8/21/24: I mistakenly reported that the solar panel wires were solid aluminum. They are stranded copper. They look to be 18 gauge.
The solar panel has a nice-looking surface and it comes with a color booklet. But you don’t have to look too closely to see that everything else is cheaply made.
I opened the connection box to see if there is a backflow blocking diode. I found the sloppiest soldering job. The screw anchor is broken. Already sign of corrosion. Of course there is no diode.
The controller is primitive and practically defective. There are way too many problems. Some of them are 1. User interface has bug, so you cannot tell which 1 of the 3 voltage menus you are in (high cutoff, discharge reconnect, and discharge cutoff). 2. Voltage reads 0.3V too high. (Not clear whether it is panel voltage or battery voltage when both are connected as there is just 1 display). 3. No charging current reading. 4. Controller auto voltage gets confused and switches to 24V if battery is disconnected temporarily. Can only reset by disconnecting solar panel. 5. Most important, it stops charging more than 1.5V below full charge cutoff.
At this point, I pretty much chalked the controller up as a total loss. The only positive thing I can say is battery reverse polarity protection does work.
The solar panel fares a lot better. It has a very hot VOC at well over 20%. In slightly cloudy sky, it can easily pull 10W. Frankly that exceeded my tempered expectation.

I have checked every connection, tried different wires, different cables, but the units third button produces no results. Considering I want this for charging phones and lights during camping trip, this is the function I need most and it does not work. For about the cost 2 battery packs you can charge all the time the sun is out, the price is good. It was about 40$ for a 12 v rechargeable battery on top of this panel and kit. I can run an inverter off the battery, but it would have been a lot easier if the usb would have worked. The 3 icon does no go on no matter what I try. Yes I did connect the battery first. Seems like I have a lemon controller, the solar panel is charging the battery.

The main reason that I ordered this solar panel is to charge my many USB charging devices, I don’t have an inverter yet for 120 volt so I can’t comment about that but the solar panel really charges all my 12 volt batteries quite fast, including large car/truck batteries. The controller does a great job of regulating the voltage and showing you when energy is actually going into the battery as the regulator cycles, very nice, and also shows when energy is going out to the load, and it shows the battery voltage at all times. you can select the battery type as well as other options I haven’t even got to yet.
At first I had problems with the output until I realized that the battery must be connected to the controller first before any other connections are made, the instructions do mention this but it should be a little clearer or in large print. I’m very pleased with the kit now and it deserves 5 stars but I didn’t receive the MC4 connector that were supposed to be included according to the listing only, so for that reason I took 1 star off, having the connectors would make life a lot easier.

This is really nice to have, I have a Lifepo4 battery in my trunk that I use for car audio, and having this on hand I don’t have to worry about having an outlet close by to top off the battery. It does push out the amperage needed in order to make it useful. I would prefer an MPPT charge controller over a PWM controller but it does the Job.
So far I have no issues with the setup and will continue to use this as a mobile power charging setup.
