The main Question is that now there is contradiction in description how the Search mode works. first is say "no-load" then it say you can adjust the "shut down" and "Turn on" levels.
What we are facing as problem is that in reality Search mode will only be active if there is litarly ZERO LOAD AC on the inverter, so what is the need for the load levels defination?!!
