Will this 400 watt off grid solar panel kit be enough to power a 40 gallon hot water heater?

Asked by: Barb
No. Use propane to run your water heater. A 400 watt system will run your LED lights and perhaps a small microwave oven and a well pump if you have enough batteries, that's about it. It won't provide hot water or run your refrigerator.

Will this one bundle kit be able to support a house

What I mean by this is will it support a house from the bottom up with 6 rooms and a big hallway with a/c units, refrigerators, lamps, etc.
Asked by: Nana
Sorry to say that this system is designed to recharge 12 volt batteries and supply power for a small RV. For the home you described, I would guess would require some 15,000 watts of power depending on the electricity required for your large appliances and other devices such as the water heater, stove, clothes dryer, AC units, etc.

I have a light that is run with a ballast that runs on 110v. A.C. draws 9.5Amps 60 Hz. Will the 400 supply the power I need? for an 8hr. run time

Asked by: Anonymous
what kind of light do you have that uses the equivalent of 17 60 watt light bulbs? Even a yard light does not use that much electricity. I lit my whole workshop with six fluorescent units (8 tubes) using less than 500 watts lighting over 600 square feet of shop space. Are you lighting an operating room? I suspect you are miscalculating your wattage draw for a single light fixture.

400-Watt Off-Grid Solar Panel Kit is rated 4.2 out of 5 by 17.
Rated 5 out of 5 by from Solar panels So far the solar kit works great bought 2 kits and haven't had any trouble running a small refrigerator freezer and lights in the cabin we'll see how it works when it's warmer out but I like not listening to the generator.

Rated 5 out of 5 by from Great Product Very satisfied with this system. Powers our hot tub with no problem. Saves on our power bill. Our hot tub is 120 volt so it works well. I have added 4 deep cycle batteries to this system and have all the power I need for hot tub and outdoor lights.

Rated 5 out of 5 by from Rv installation Was pretty easy to install. Tech support people were very knowlegeble patient helpful and responded promptly.took a little planning Where to locate inverter and charge controller to minimize voltage drop. How to get conductors from roof to charge controller in basement (I went through plumbing vent roof flange and fished through wall. Others use the refrigerator vent chase. You also have to design your own roof panel mounting system. Was easy, I used short pieces of 1 1/2 aluminum angle to mke mounting brackets and all stainless fasteners to avoid galvanic corrosion. Then some aluminum flat stock for support rods when rotating panels up for proper sun angle. Don't forget to order a few tubes of Dicor self leveling caulk to seal roof penetrations.

Rated 5 out of 5 by from Off grid power Unless you're planning on running an air conditioner this unit is perfect. I run this unit with three 100 amp our AGM batteries. During the day when the sun is out it is amazing. At night it runs a ceiling fan, 4 LED 60 W lights and my laptop and television without any problems whatsoever. If you want more power just add another battery or two

I needed it to work at night and it only worked for 2 hours . I wish I would not have gotten the kit the day after I ordered it they dropped the price down $200.00 dollars . Then I had to spend $300 on a battery... The solar panels did look good upon top my shed but I took them down and put them in the shad . I had to go back to running the extension cord across the yard. I am unhappy with this ...

Rated 5 out of 5 by from 400-Watt Off-Grid Solar Panel Kit This kit is for the beginner solar enthusiast .... It is very easy to assemble ... It does not come with a battery, but, you can buy batteries (deep cycle marine batteries work well) just about anywhere .... It provides sufficient power to run a 16' above ground pool pump 24/7. ... But, those of you that are looking to power much larger loads should know that this is not going to work. ... The kit does not require any special tools and can be relocated with minimum effort .... I learned enough from putting this kit together and operating experimental projects that, I think, I can build one from scratch ...
