I am a software developer and electronic designer interested in energy management products. When I bought this product I had no illusions about it being of any value. So I haven't tried to get my money back. I bought it to write a review.
It's hard to decide where to start. First, the power calculations are way off. There is no way to use the parts shown to generate the kilowatt hours per month claimed in the literature. Second, the parts shown cannot be connected to the grid. It is illegal to use a 100 dollar modified sine wave truck stop inverter to feed power back to the power company. A synchronizing grid tie inverter is required. They cost a lot. The connection he shows could start fires, damage power company equipment, and kill power company workers. Don't hook it up.
About a year ago I asked them about their inverter and they told me, "That is a very good question". I haven't heard back.
I think Power4Home has gotten over their delusions about knowing anything about engineering. Now they seem more interested in sending me email tips like 'How to install a low flow shower head' and 'How to get servive your water heater'. Pretty soon I'm just going to put them on my spam list.
