But, when power is no longer available or coming in, the automatic transfer switch built into here transfers the AC1 circuit only to be powered by the inverter. So, what that really means is it's pretty much like a UPS unit if you've used them before. If you look on the back, you know, there is what they call like surge only, right? And then there's another chain of circuits which are battery backup.
That's pretty much exactly what's happening here, right? Except on a, you know, much larger scale, so to say, mainly because AC2 out is not powered when AC in is has no more power, and then AC1 is always powered whether you have AC power or not, right? The beauty of these transfer switch units also is that besides it being automatically built into the unit is also is that it's a really fast cutover. So, if you have sensitive electronics, you don't really have to worry about
