Not sure what kind of APS you speak of but yes, needs to be an inverter in line. Most non-motor stuff can take pretty good variance on 60hz (50-70) and usually 90-130 vac. DC stuff is usually just a volt or 2. Big problem with the 'grid' switching is making sure the 'line' is started in-phase and freq. Takes time to get MW generators miles apart synced. Not synced and really bad stuff happens. Can't just throw the switch.
Oh, almost 50F now.
One something like this for the house.
