"All seems to be well here. The system is working very nicely and has reduced our consumption from the grid from about 8 units per day to about 1 unit per day. I did the power-cut test by turning off the mains in the garage with the garage lights on. There was nary a flicker, and the broadband internet services continued uninterrupted - very impressive. I am also extremely pleased to say that, so far, I have not detected any radio interference."
