nope, not at all. Ive seen some invertors probably like your trace, when in standby mode, reduce the PWM to very small ratios, so they still generate mains AC , and then rapidly switch to full mode once a triiger current
is detected. Those sort keep clocks alive becuase they are in effect generating mains.
Today, usually a pulse is sent out to energise any potential load, then the switcher starts up. That type of invertor basically shows 0VAC at the outlets and doesnt power up clocks or anything, ( its actually a mode I dont like anyway)
