Rated 4.8 out of 5 by 5 reviewers.
Rated 5 out of 5 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 out of 5 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 out of 5 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 4 out of 5 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
Rated 5 out of 5 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
