Answer: 
Not even close, your house will need something on the order of 10-15 kiloWatts. The 400 Watts is only 0.400 kiloWatts, so you can see how little it produces. The converter will be good for powering things like low wattage lighting, battery chargers, computers, small radios and TVs, but anything like an appliance such as coffee maker, microwave, A/C, heater, washing machine, etc is way, way out of the Read More

Answer: 
Most houses today have 110volt, 200amp service. Watts = volts x amps (roughly) so expect 2,200 watts for your electrical needs. You may respond with "I don't run everything at once" and that is true, but appliances with large electrical motors (refrigerators, washers, dryers) can draw in a surge of power that is several times its normal consumption.

Answer: 
The community answer is incorrect. There are 400 watts of total DC panel power, this has no relation to the output. This product will generate, on average, 1,200 watt-hours of usable AC power per day. This is enough to power most smaller fridges, and maybe some LED lights or cell phone/laptop charging. It is not large enough to run a house or even a single AC unit - contact quotes@grapesolar.com for an Read More

Answer: 
if my research is correct...
With PWM controllers Input Current = Output Current
With MPPT Output Current = Panel Wattage / Battery Voltage.
what you have describe is the MPPT charge controller.

Answer: 
Hi John,
The 35A you see listed refers to the output amperage, not the input amperage. Because the panels have a higher voltage than the the battery bank, the charge controller has to step it down to match the preferred charging voltage. When it does this it increases the output amperage. If you place six 100W panels on the charge controller the increased amperage will exceed the 35A output limit.

Answer: 
Hi Barb,
Thank you for your interest in the Grape Solar GS-400-KIT. The average 40 gallon hot water heater consumes between 4,000kWh and 5,000kWh per year. Unfortunately, this system will not produce anywhere near enough power to operate the hot water heater in question. Please feel free to contact Grape Solar Customer Support (877-264-1014) for assistance in sizing a system for your hot water heater.

Answer: 
no
power or watts is = to voltage x amps in this case you have 400 watts available but are needing 1045 watts (110v x 9.5 amps = 1045) also the panel only produces power during the day if used at night you would need a battery backup.

Answer: 
Hi,
Thank you for your interest in Grape Solar kits. Based on your description above, the 400-KIT will not even come close to powering your light.
A 110 volt light at 9.5 Amps is 1.045 Watts (110V * 9.5A = 1,045W). To run that light for 8 hours per day requires 8,360 WattHours (1.045 * 8 = 8,360Wh).
If you want to run the light every day you would need 3,051.4kWh per year. ((8360 * 365)/1000 = Read More

Rated 4.8 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by 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 October 5, 2015
Rated 5.0 out of 5.0 by good products, pricey it's a good kit, but a bit pricey. you can buy the pieces individually cheaper. July 14, 2015
Rated 5.0 out of 5.0 by 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 ... July 2, 2014

Rated 5.0 out of 5.0 by Customer service is tops everything was delivered timely and was stored for a week before installed. when I opened box one panel was broken but I went and installed everything and set it up with the batteries I had.. Everything seams to be working fine. Monday I called HD customer service and talked to Amber. She took care of everything as far as replacing panel and having it delivered to my house no charge. I received 5 days later and installed panel. Way to go Amber and HOME DEPOT thanks for the great service - I'll be back! October 29, 2014
Rated 5.0 out of 5.0 by This system is great for peace of mind and performance in case of power outages at home. This is a complete system which is easy to assemble and install using the enclosed instructions. After testing it under a load consisting of a 5.2 amp refrigerator, large TV with a surround sound system and miscellaneous fans and lights, I was pleased to measure that I had plenty of voltage left on my 2 large 12 volt batteries after my 7-hour test. I intend to use this system as a stand-alone emergency power source during power outages in my home in case my small generator runs out of fuel. I love it. July 21, 2014
Rated 5.0 out of 5.0 by I guess it will do I don't know about the features or functions. I checked the box content when received. Looked all there and no damage. It will stay at the Lake House unopened until the USA crumbles and hope it will help us to survive. April 1, 2014
Rated 4.0 out of 5.0 by Simple installation The harness system was made incorrectly, which allowed negative voltage into the controller. Once corrected this unit works well, nice inverter. I took this with me to an event had a lot of interest and views. October 30, 2013
