    Hi All, I am looking some advice regarding what device/s would be required to do the following: I have a fairly heavy duty UPS (APC 2200VA, supports max of 1980 Watts - it's pure sine wave if that makes a difference).

    Sunny Backup

    Is Sunny Backup available in the Uk - is it G83 approved? I have a customer who wants a 4kwp system with some sort of backup for the 4/5 times a year he gets power cuts. I'm thinking even if it's available it's going to be too expensive????
