For an Off Grid backup, this generator has met all my needs and more. The setup and operation is simple enough for the whole family to use. The key fob means that I don't have to go out in the rain to turn it off. The two wire start gives me the confidence that if things go south, the generator will kick in before disaster strikes and keep everything working. I also bought the smaller 4000 ESi as a general backup to a smaller Off Grid installation and I'm just as pleased.
One last comment about Proline - After making an online enquiry, Proline invested the time finding out exactly what I was going to use it for, sizing and my general needs. Add to that the after follow up service checks show that Proline really care about their customers. Excellent Customer Service, bar none.
