Ya I hoped for that as well. The thing is very sensitive to power fluctuations which actually makes it work really good especially in my area. Where I live the mains have auto-breakers so if a tree or something touches the line they will trip but then re-engage a few seconds later to see if the fault has cleared. They do this up to about 5 times and it creates a huge surge in the house on-off on-off etc it's horrible for sensitive electronics. Use to have to run across the room and shut off the tube amps and other radio gear I have on. That never happens now as the Powerwall switches over so fast and wont switch back until it has about 5 mins of constant mains power.
