solar energy store

ran into Solar energy store when I was looking for backup system for my home then I contacted them. They told me they only operate online as an online store which seemed a bit shady to me so I did not purchase the same day I wanted to make sure they legitimate. After 3 days I decided to place an order of simply a 5kva inverter(Five star) with 8x 100AH 12v gel batteries(Goldshine), and they actually delivered after 3 or 4 days and everything came in mint condition. I'm giving a 3 star because communication was not too well with clients.
