What does this power? Fridge, AC, or just lights, recharge outlets etc. how many marine batteries does it take for this much solar?

It depends on how long you intend to run the appliance. Frig. 3-4amps @ 120V = 420 watts. Divide by 12 = 35amps per hour. Typical large battery has 150 amp hour capacity but not at that rate and not fully discharging. Regular batteries are cheaper and you will only discharge to about 11.5 volts. That is why most residential system use line inverters and sell back to the utility. My starting point would be 10 if I was seriously wanting to benefit from a generator / battery backup on these appliances.. A couple of batteries could take all the charge a 100 watt panel could produce for days. Store it, use it or lose it because you can't afford your design intentions here.

The controller charges 12v batteries, and its ment for turning on lights at night from battery power. The controller feels cheep but I like the panels, I have 4 panels charging a 48v golf cart, and an inverter in the cart that can run almost anything you plug into a standard outlet.

At 200 W it puts out 12 V DC charging for deep cycle batteries. You can expect anywhere from 7-11 amps at peak power generation. You can also use it in 24 V mode, and expect half the current to the batteries. It will keep your batteries topped up. You can then use the batteries like you normally would, whether they power an inverter to power 110 appliances, or just 12 volt accessories. You can expect about 1 k-W-hr from these panels, with the 5 hour approximation rule. Should be enough power to recharge a 125 ah deep cycle battery, assuming a 50% discharge.

If you plan to use this with an inverter attached to the solar charge controller, the amount of current being drawn from the battery is dependent on the solar charger and the inverter. the solar charge cotroller i use does not allow for more than 20 to 25 amps (300 ac watts). If you run the inverter directly off of the battery, you can use larger wattage inverters. The simplest way to use these panels is to hook them to the solar charge controller and hook the batteries up to the charge controller. Then hook the inverter of your choice up to the batteries. I use a 2000w samlex sine wave inverter. This covers refrigeration and recharging sensitive products. If you plan on running these to your electrical panel, you need an electrician to figure that out. I used these panels for my solar generator project. They worked great. The 2 panels combined give you about 10 DC amps of continuous power (about 120 watts of continous power). Without getting technical, It would take about 8-10 hours to charge a 100 amp hr deep cycle battery. How long that battery lasts depends on how much power you draw. Definitely can't run central Air conditioner with 120V. You can run a fan, lights, refrigeration. Your limitation will be the alternate current 120V inverter and the max continous wattage.

how long can this take to recharge 200ah 12v battery from 50% drain and completely drained level?

I actually have 4 of these 100W panels, with 3 VMAXtanks Vmaxsir 125 AGM deep cycle 12V 125ah rechargeable batteries. Today I ran 3 circuits in my house. One for the computer, the A/C motor on my central A/C, and my refrigerator. This configuration is exceeding my expectations!

The solar panels are for charging batteries. You will need batteries and a 220 volt inverter to power the refrigerator. 4 panel will not be enough to maintain the charge with your refrigerator. I have 10 panels charging 14 deep cycle batteries connected to a 3000 watt, 120 volt inverter that powers a small chest freezer and some lights plus occasional microwave and TV and I am probably going to add another 400 watts to my system so I can have a small refrigerator.

the only thing i can tell you is my own experence.,i had it hooked up to 1200watts of solar with 1000amps from 10, 100amp 12volt battery bank.,and it wouldnt start my house refridge..it has 2/3 seconds of surge power.,the house refridge need 10-15 seconds of surge power.,if you dont need surge power,,its ok i guess.,,im not useing it..it doesnt work for me.ill give you a deal if you want to buy mine half price.

I had an old 1700 watt generator during sandy. It powered my fridge and a bunch of other small things. The 3000 watt inverter isn't overkill tho. It won't draw more power than it needs. Battery needs to be good and charged as much as needed. Car alternator at least. Cables need to be thick for 3000 watts.

It takes two rechargable AA solar batteries. They can be found with the other solar products at stores or on line.

Every receptacle can hold about 8A. And 2 receptacles can hold total 8A. The freezer needs very high current when they startup. You will need to buy 2000watts inverter.

The inverter is a 3500 W. 4 1500 W equals 6000 w. That would mean you would need 2. I use this inverter on my boat. It runs a household refrigerator of approximately 1800 W. The best thing about this inverter is that it will shut down if it is back fed. Since I switch from AC to DC this feature is extremely valuable. I would recommend this inverter because I have tried Xanax and I burnt out 4 them. As far as the amount of battery you need it all depends on how long you going to run the unit.

Hello Sharon, Thank you for your interest in our products. The SunSocket Solar Generator has a 250WH LiFePO4 battery and a 100 watt inverter. The maximum power output is 100 watts, with the 250WH battery you can run a 100 watt device for 2.5 hours with no sun. The unit will run some portable refrigerators but not regular full size one. I hope this helps.Sincerely,AspectSolar

The fridge draws about 30 Watts of power when the compressor is running, and when running in freezer mode, it will run the compressor most of the time. That means you'll be drawing 20-30W, or 200-300Wh over the course of 10 hours. For a 12V battery, that translates to 17-25Ah of battery capacity, plus any inefficiencies (some cars will also require you to have the ignition on to use the 12V sockets, which could add to the power draw). Given that most car batteries have capacities around 40-60Ah but only about half the capacity is usable, keeping this fridge running in freezer mode overnight is not advisable. I would recommend getting a second deep cycle marine battery so that you don't run down the car's main battery.

Just an opinion here, Kindle Customer; If I were you and had 'that' kind of money I'd get kit anyway and 'go solar' for just part of the house--part of the kitchen comes to mind. Right off the top of my head I'd have somebody wire up the hot water heater, fridge, and maybe a light. Check the wattage for all three and see how it matches up. Plan B would be to wire up a window air conditioner. Futher, you need to remember solar panels work best with batteries hooked up to them.

i dont take it off my battery ,i run a 1200 watt inverter in a 3/4 inch box with a lid which has a cut out for out lets with a dome light cig lighter and alarm with toggle switch out side has a poly rope rated for 500 pounds rolled up handles on each end off box, i run a small compressor with a 90 led watt bulb plus my 32 inch led tv and a 300 watt heater and lap top.i dont run it all day its my er travel pack. i can run it for a week full charge on my 12 volt battery charge time may be a full week for a low battery, i use a marine battery and 150 amp fuse hook up just in case. the main thing is the solar panel facing direction and elevation direction . my plan is to go off grid in next few years.leave it hooked up and leave it alone.. this is all new to me but i must say what i done works for me, good luck out there ..i own a solar book and read that it dont pay to go 100 percent off grid at my age but if your young start now if thats your dream.

all the panels do is charge the batteries. if you have enough batteries you can run anything. These panels charge a 125ah battery in about 7 hours in good sunlight. you need to find out how many watts the refrigerator is and convert it to amps. amps = watts / volts. 125ah battery can run 6.25 amps steadily for 20 hours. Here is a write up i did about solar power and power conversions. On a good day i get 18a of charging power from 400w of solar panels. good luck. I put an example of a refrigerator in my blog.

15 amps. NO! My 27 cubic ft home refrigerator doesn't use 15 amps. Double check your numbers. Also, you can't run any 115 volt device off a solar panel. The panel charges a battery. The battery runs into an inventor. The fridge runs off the invertor.

only has 2 voltage settings gel cell which i think is 14.1 volts and lead acid or wet cell batteries at 14.5 volts which is the right voltage for deep cycle marine batteries. I'm running 2 deep cycle marine batteries and it works great. with two 120 watt solar panels I have seen 17.3 amps coming in. at 14.5 volts that's about 250 watts gotta love it. This is a great controller for anyone with a small solar panel system, it's not a mppt controller but it's also 1/5 the price. I got it before it was on sale paid $130 and it's still well worth that. I'm not going to complain I have been using it for 6 months and have no complaints. see my photos.

If you had it hooked to a large capacity battery. With a inverter hooked to that battery large enough to handle 115vac @ 5amps. The amps for a small fridge is probaly closer to 1.5 than it is 15 amps. So with your panel in full sunlight producing 50W at 22vdc regulated to 12vdc. You could in theory run the fridge.

You would want to use this in conjunction with a deep cycle battery even a marine deep cycle like those sold under the blue "Ever Start" label at walmart even and a 10 amp or greater "Solar Charge controller" and a "ac power inverter" for running things like household AC lights/laptops/small appliances like blenders and coffee grinders and even short uses of a standard 700 watt microwave! Pending your geographical location (I'm in Oregon) I get about 35 to 45 amps of battery charge on a late spring through summer average sunny day.. (6-7 amps per hour) That's enough for me to keep my laptop running 24/7 and 3 or 4 8 watt CFL light bulbs in standard table lamps for 6-8 hours a day! You can add more panel and more batteries to expand your needs and to compensate for lower sun exposure areas.. I highly recommend searching the internet for a basic free "Solar how to and intro" page. and also a search about using and maintaining "Deep cycle batteries" (You never want to drain your batteries lower than 50% between charges) It all sounds overwhelming to a beginner but once you do a quick study you will be hooked! ~ Hope this helps ~ Nick

This is primarily a 12vdc device. You would need to set up batteries with an inverter to run your AC operated devices, and you will most likley need two or three panels to keep up with the demand.The batteries would need to be enough to run your heat lights all night I am guessing. Knowing (calculating) what your power demand is will be key to proper setup. That will tell you the number and capacity of batteries/inverter you will need and the charging demand you will need taking into account cloudy overcast skies (winter weather, etc..) when a solar panel is not as efficient.
