Rated 1.0 out of 5.0 by Henry Don't compare this to a serious off-grid system!
If you are interested in a real off-grid system or a grid-tied system with battery backup for standby power, this is not likely it. It will run some small things for a short period of time, but keep in mind that depending on where you are, 140 watts of solar is going to generate, at best, 100 watts of AC power. That means that you could not run a 100 watt lightbulb for perpetuity. The size of the battery bank will determine how long you can go, but running a 100 watt light bulb will eventually deplete the battery bank because you don't have 24 hours of sun each day. Google Shockoe Solar and check out their website if you want to learn a little more. The site contains lots of information.

Rated 5.0 out of 5.0 by theoutdoors4life Impressed---Much better than a gas generator
Wow, I live in a condo association that does not allow the use of gas or propane generators. I found this online, but admit I am not a solar expert. It was simple to install....just plug wires into obvious ports. (I called customer service once, extremely helpful and they even sent me a link to an installation video they created that shows each step of how to install and confirm I did it correctly). It is completely silent, good for the environment and it worked great! My neighbors are all on-board to buy more for association members. Most of the time I plug it into the wall when the power is restored and the charge the batteries back to full. They last a while so I have barely even needed the panel yet!

Rated 5.0 out of 5.0 by kory This product saves money and pays for itself
At first I was not feeling to good about the price. It was very expensive and I thought that it wouldnt work out to pay for itself; however, after I decided to buy it started cutting my electric bills by major amounts. i work all day so my house uses little electric during the day and at night i have a few lights on and the tv, so basically my electric bill was very minimum. Winter rolled around and the heat needed to be turned on. my eletric bill rose in the winter, but only for the heat. over all i am very impressed with this product.

Rated 3.0 out of 5.0 by TheNavigator Some things to consider
This is a good basic system but it does not have a pure sine inverter which can be harmful to some electronics. If you do some research on batteries, many pros recommend 6 volt golf cart batteries connected in series - these batteries cost more but are designed for many more charge/discharge cycles. Marine deep cycle batteries are different and are designed/constructed differently from golf cart batteries.

Rated 5.0 out of 5.0 by Nick Wonderful product at a great price, and free shipping, even to Hawaii!
I was researching buying the components to build one myself, but finally realized that it would be safer to get one that was already put together. Recharges battery in about 5 hours of good sun. A larger solar panel might improve charging. Battery voltage goes higher with AC charging. Would have wanted a pure sine wave output. But thrilled with the product.

Rated 4.0 out of 5.0 by beck7601 good product
Know what you are ordering. This unit is not a pure signwave inverter....that means some rechargable devices will not work. No it does not come with batteries, and when you get the Exide batteries, they do not have hex nuts. That requires a trip to the hardware store for 2 3/8 inch coarse thread nuts and washers [ mine were 13 cents each]. Hook up the batteries first and then plug the battery box into the inverter/charger[ otherwise you get sparks]. Keep the shipping foam to cover the solar panel when installing [ keep it in the dark until it is hooked up]. Always hook up the charge controller to the inverter first and then to the solar panel. Highly reccomend a DC disconnect switch between each panel and it's charge controller.
This unit is not perfect but it gives you a chance to put together a system using wind and sun and provides emergency power for many uses. There will be better units in later years but this on is here and now. I like it and reccomend it.

Rated 5.0 out of 5.0 by GreatGen1 Excellent Solar Generator
Generator works great for our needs. Easy to install and it ran our TV, lights, and small electronics because our power goes out for short periods periodically. Big Help!
