My problem is the intermediate blackouts here, I like the ecoflo panel as it switches over in zero time, a millisecond. I tend to leave my rig on 24/7. I admit, I just started looking into this, so I am not up to speed on the various solutions.
It won't switch in 1ms. Its more like 20.
You have to consider your budget and what you want to backup. Do you need the transfer switch.
The marketing material makes it look easy. Code is going to throw wrenches into any installation that has a transfer switch and ties to utility power.
Using it for audio is a different subject.
