Looking to get a solar option for charging laptops and small electronics in my van (vandweller). Would this work? or need x2?

This system is designed to charge a 12V battery. I use one on my popup tent trailer to keep the 12V deep-cycle battery charged on long camping trips. This setup (with a deep-cycle 12V battery) works quite well with my small laptop (and DC charger), iPad, and Android phone.

this kit will work way beyond that as long as you have enough batteries to hook it up to.it can charge your van battery and run 12 volt appliances through your cigarette lighter or run 120 volt appliances with an inverter that can handle the amount of watts you want to use.be careful of sensitive electronics while using a cheap inverter.you may need a sine wave inverter.i would highly recommend a good group of deep cycle batteries.the more batteries the more you can run.check out youtube for lots of answers.hope I was able to help

Depends on how many batteries you have. Gc2 everyready 6 volt golf cart batteries from Sams Club should be enough. And your location also is a factor.

This is really for charging 12v batteries. Not aboe to directly charge laptops, etc, becuse the output in 12V from the controller. We use this on our RV to charge 4 marine batteries with the 30AMP controller, and run inverters to run appliances. It would be overkill to use this with inverters just for basic recharging, but it CAN be done.

Hi,1 panel is 100w, that's good enough. If you have 12V, light bulbs in ur van, you can connect 2 or may be 1 12w bulb. You will still be having 88w to be used, u can charge ur laptops and small electronic appliances. Good thing about this panel is that, these are expandable. You can buy 1 more panel later on. If u decide to buy 2nd panel, just buy panel alone that Is around $149. U don't need charge control with that.. Thanks,Masroor

Yes this will work. The whole purpose of having this controller is so that once a battery is "fully charged" (at ~14V), this will "disconnect" or "shut-off" the charging so you don't get the battery up to levels like the 17.5V you mention (where it will damage the battery). Even if the solar power is at levels like ~30V (while it's not charging the battery), this will still function blocking the solar power from getting to the battery until the battery voltage comes back down to 13V where it again lets the "charge" power thru.

Unless the Laptop chargers via a USB Port, then I don't believe so. The solar charger has a USB out which delivers 5 volts DC. Most Laptops have a transformer connected to a cord which requires 120 volts AC. I would also assume that the laptop battery itself probably would require at least 12 volts DC or more if it could be charged directly. You could get a regular solar panel to do it if it was connected to a 120 volt AC inverter.

Depends on the wattage of the load and how long you will run in hours. It will work with a 100W panel fine. You will need a charge controller like the Morningstar SS-20L-12V SunSaver 20 Amp Charge Controller LVD. If you plan on running AC device you will need a little DC to AC inverter as well.

No. Two panels on one battery will not work. Waste of money only one panel needed if using as a maintance charger. If looking at using as a power supply to a cabin this is not the setup you will want. Would need larger panel and controller for that purpose. This unit is strictly a 1.25 amp charger for maintaining a battery in storage. Like my old beat up pickup that is used once or twice a month and sets outside all the time. Keeps the battery in top shape and counter acts the lite drain of the factory radio and computer in modern vehicle.

Yes, it should work. You'd honestly be better off getting a second solar panel and wiring them in series to produce 24v.

All Depend on what you are using the solar system for. I have two of these battery charging a small fish pond with total of four pumps, that not of enough battery. I have 200 watt system, use as many battery of same size as you can afford. Good Luck

I am not sure if this cable would fit or not, but technically speaking, you can connect two solar panels in series to get double voltage as it produces a pure DC voltage just like batteries.

JD - Kindly edit your response, it is .3 of an Amp, not 2.4. Also- I would LOVE to know what kind of a controller you use with the solar panels and batteries.

You'll need something to mount the panels to. The batteries will need to be connected with heavy gauge battery cables. I keep my batteries in a ventilated box out on the deck, so you might want to have a container in mind. It appears to me that this kit will provide charge for 12V batteries in parallel. You will need an inverter to turn that battery power into AC power so you can plug things in. AC inverters come in a wide range of power outputs. 200W inverter will power a laptop. Do a google search for "how many watts do appliances draw." This will help you pick out an inverter. (A space heater might need a 1500 W inverter for example. Cell phone charging can be done off of a 150 watt invert. Buy a bigger inverter than you think you will need. Good luck.

I would keep the configuration the same because you will above 13 volts to charge the battery. If your looking for amperage in series, it's best to have a power capacitor wired on the 30 amp solar controller battery input side, and the output on the capacitor to the battery with a resettable 20 amp fuse on the red cable to the battery. The capacitor depending on the Faradays you pick, will act as solar storage and help the backup battery recover fast if your running an AC Inverter on the battery output cables. Remember these panels are only outputting at 35 watts, so the amperage is low and need capacitors for storage.

Am sure it would since small solar panels don't generate much in the way of amps. The primary concern would be what is the VOLTAGE output of the panel. A conventional battery charger is capable of putting out about 13v max. Hope this helps----I am not an electric fence wizard but I do have a lengthy background in electronics.

Depends on your battery set up...doubt one panel will get the job done. Works great for my RV though.

Sorry, I can't see how that could possibly work as this device charges AA and AAA sized batteries from a standard 125VAC outlet/power source. I have no idea what would happen if you connected and 12VDC battery or solar panel to it, but I'd bet that it wouldn't be good. A better idea would be to find a small 12VDC to 125VAC inverter to connect your solar panel to, and plug this charger into the inverter. Yet another idea, see if Duracell, Energizer, or any aftermarket manufacturer actually make an automotive/12VDC charger. Good luck.

This is a good solar panel. I have 2 batteries connected parallel, + to +, and - to -. This gives me the same voltage- 12 volts. I run my garage door opener and some accessories in my garage off a power inverter. The Ramsond solar charge regulator shuts off when batteries are full. Like T.J. said, make sure you aim the panel for best results, and hopefully its not foggy where you keep your boat!

I am not sure if you are looking for a battery or solar, the solar I can answer. For a laptop you will need the highest wattage you can get. You will also need an adapter to go from the Solar charger to the laptop. I do not know if you can find one on line or have to make it, that "PLUG" would have to atatch to your battery port on the laptop. I have a "SOLAR 12" It works great on my tablet even while I'm using it. I hope this helps you. SPM

I agree with most all said here before. Get 2 12v batteries in series = 24v, or 4 6v and hook up in series but controller is best way to go to match your solar panel. Most quality solar panels will charge 12v and 24v. Get a volt meter and check it out as you go. A fuse is a must. Good luck
