We have a large late model Sharp Microwave, it's used for thawing pet food. I don't like microwaves for a number of reasons but that's a different story. This Microwave has a clock that is obviously synced to the mains frequency. Some inverters cause it run slow after a few days. The last EG8010 inverter kept time, some previous inverters also based on the EG8010 did not. ..snip.. . Thanks for this info. it seems that the EG8010 60Hz selection is not accurate. My pool timer which uses a 60 Hz synchro motor runs slightly faster when driven by the EG8010 based inverter. Even when I added an LC Pi filter at the synchro motor power line.
