Renogy review: Off grid tiny home kit

i am building a house so after 3 different representatives telling me that their $7500 kit would power my 1000 sq ft kit I bought it. they are LIARS! 90 days later my contractor and electrician are ready to install and both said NO way that kit will power my house so I called back and the 4th representative told me that the kit they sold me would NOT power my cottage and that I needed to buy another $7500 kit. are you kidding me? I would have NEVER paid $7500 for anything that I cant use. they have doe nothing and will not refund my money after 30 days. they are LIARS and SCAMMERS
