Questions & Answers

Would it be possible for you to provide me with the dimensions of the controller? Because the company claims it is not waterproof, I am searching for an enclosure that is nema rated! ?

As far as I can tell, the controller I received is a Two dimensions of 25 inches by two dimensions of two inches. The dimensions of the image are 75 inches x 1 inch. The diameter is 25 inches. It might be a good idea to get a container that is larger than You have room to connect wires with a distance of 25 in.

The solar panel would allow a 12 volt 35 ah battery to be charged within a few hours. But how long would it take? Currently, I live in the sunny state of California. ?

A 30 watt peak output will lead to an output of about 2 watts at most. There are 5 amps in 5. Imagining that your battery is 50% discharged, you will need to replace it somewhere between 17 and 18. If losses were included, I would estimate it to be The sun is on for 8 hours and a half during midday. I would estimate around two days with full sun.

A device that uses 10 watts of power needs to be powered. What can I do to determine if the product will work?

In addition, both the panel and controller are capable of producing The current draw will be approximately 5 amps at 12 volts).

What is the best way to set up panels in a ?

Yes, of course. While you're driving, the mirror can only be inserted in the windshield. There are quite a few of them. At the moment, mine is in my tent, but I would estimate that it is about As far as parking it like an RV, it would be fine, but I wouldn't drive around in it. There are no flexible options here. When I wash mine, I stand it right up on the ground and clean it against the hitch of I was able to run lights and charge three cell phones while it kept my battery healthy.

There could be a better way to set up controller instructions There is a timer on it, though! The four BougeRV mounting brackets made it a breeze to attach this small panel to our backyard gazebo's roof As of now, the EV charger is charging a Mighty Max SLA battery to power Twelve Volt It is another matter to deal with the controller The box appears to work as expected, but the set screws on the tiny wire terminals make it difficult to connect, and the one-way latch is hard to use There are limited instructions in this page folder, but they are written in a disjointed manner
4/5

The way to change the settings is not intuitive In fact, it is pretty much something you need to figure I think you're right The discovery has been made! The settings contain a timer that adjusts how long the load will be powered on after the panel has stopped producing electricity - and this can be done by either setting the timer to 1 or 2 hours. As the sun sets. For example, if you plan to use an external switch or motion detector, or if you want the light on always, you may leave it at 24, the default setting.

It is perfect for off-grid power generation, derp cycle batteries, and off-grid equipment
5/5

It arrived in perfect condition, and the parts functioned flawlessly after being tested. I had to make my own mounting brackets since I was not provided with any. My battery charger was able to charge my deep cycle battery perfectly, but the instructions were unclear about what the buttons did. Although I am trying to figure out the dusk till dawn option, I cannot set the timer to use power output. The rest of the product is great!.

This is awesome
5/5

With Lowe's aluminum strips, I mounted the solar panel onto the roof of my Jeep and attached it to the battery box so I can charge my spare car battery during the day and power my electronic devices at night using the panel. While both USB outlets are included on the unit, I prefer to use the ones on the box. Upon installing it, the battery was 79% when I turned it on, and after a 5-minute charging time, it dropped to 82%, and I just left it there and it's been 100% for weeks and months. I think this contraption is really cool!.

This is not a new issue
3/5

This is a terrible piece of work. Thanks to that panel, I got my work done! It's hard to imagine brand new panels with scuffed surfaces, scratches, and improperly stripped wires. This is a poor-quality piece of work. As a result, my hands and arm got scratched up because the manufacturer didn't even bother to align the corners. Aluminum corners that are razor sharp. There are more scratches on the screen. I urge you not to purchase this product!.

With a 12v water pump, it's a great solution
5/5

SUMMARY I needed to run a 12v water pump directly from the output of the charger without using batteries. The charger arrived packaged well, and the instructions were easy to understand. Due to the spike of current needed to start the pump, it is not possible to do so. There was a small 12V battery that I had to add, but it worked fine after that. A switch on the charger for the output line allows it to be turned into an on/off device. The only complaint I have is that the wire that exits the panel could be a bit.

This kit is functional and attractive for the price
5/5

I bought it for use on a chicken coop, together with an old motorcycle battery, a shelly one smart relay, and a spare 12v led light, it makes a nice low voltage lighting system on a budget. Despite this, there are some limitations of this charger that you should be aware of before you purchase As the panels stop producing electricity at the end of the day, the built-in timer is only a delay from sunset. When using this for a chicken coop, it is best to set it so that it is always on and use a separate timer or smart relay to be able to turn it back on before sunrise. It is also not entirely compatible with the provided manual, particularly the instruction about changing between flooded and absorbed, as well as gel batteries. When you are using fancier batteries, or if you care more about keeping them in good shape, it is more important to do this. Besides that, the set I bought was right about $50, and I can't really complain for the price. It's not as nice as the solar installation on my RV, but it also only cost about 10% as much, so I can't really complain. In light of the price, I would still rate this solar kit as a 5 star product.

As long as the setup is done correctly, it will work
4/5

A solar panel mounted on the roof of an RV to charge batteries while in storage and for other purposes While the batteries are charged, the charger should be on during the day. There is no way to change the setting it says it will automatically set to 12/24vdc, but I connected the solar panel to the battery first and then the battery to the solar panel and it remained in 24vdc mode. The first thing I had to do was disconnect wires and connect battery before I could use the 12 volt There are too few wires and the manual is difficult to understand, according to others. A strip of aluminum was purchased at a hardware store so I could make brackets that would mount the panel at an angle, so dirt wouldn't accumulate easily (see image).
