[RE-wrenches] Chevy Bolt

[Jay]

Hi Darryl

It has to do with the zero point crossing. 
With pure sine wave, it crosses almost vertical angle so no time spent there.  Mod square wave usually has a flat crossing, totally screws certain things up.

Causing failures when the switching is coincidental.  I forgot the exact reason but I have failed equipment using a modified square wave inverter on portable tool charging equipment.
