Even my 25 year old Trace 2012 does this in search mode, but as Paul said about once every 5 seconds looking for a load. Funny
thing, that short little power up looking for loads was enough to keep my VCR clock keeping time. If memory serves, if I set the threshold so low a wall cube for charging
would keep it on, then for 24 hours per day I would be wasting about 300 w-hr for the inverter to always be on. If left in search mode with a higher threshold it would be 1/10 the drain.
I had to use dip switches to set my parameters for search threshold, voltage and current for charging
, and a few other things looking at the instruction sheet. I hope the new inverters have a better user interface like a screen
menu and function switches.
Welcome to the world of inverters and power saving of your stored electrons.
