Commercial voltage optimisation

Maybe. But the fridge that keeps the beer cool is on 24/7, so sod waiting for the kettle!

And there was me thinking in terms of morning coffee's, rather than eveing beers!! lol!!

Motor loads will not benefit from voltage optimisation.

The governing factor is shaft HP. Lower the voltage and you’re heading for trouble!

Most AC induction motors that i have come across, have always had at least a manufacturer's tolerance of 10% and often 15%!! Can't really see a voltage reduction of around 10 volts is going to make much of a muchness to be honest...

If you want to improve motor efficiency surely it's better to run them through a vector drive inverter that ensures full saturation regardless of load and minimises copper and iron losses.
