So I found this: https://diysolarforum.com/threads/understanding-aio-idle-power-consumption.41017/
Which is somewhat close to what I'm asking but not quite... I see values for "idle power consumption" in the spec sheets of a lot of these inverters/AIO's ... but what isn't clear to me is which mode (modes?) of operation these idle values do and don't apply to.
If I have one of the AIO's that functions as an inverter/charger/transfer switch, and we assume that "normal" operations is with the AC mains connected, this means that the vast majority of the time the inverter isn't actually doing anything, right? It's just periodically checking the voltage on the battery side, and if that's below the threshold it clicks on the charger function, then clicks it off whenever the high threshold is reached... in the meantime, the AC mains power is just being passed through the transfer switch to the AC load side, right? So I would *think* that in this case the power consumption of the inverter itself when not topping up the batter would be VERY low (maybe just a couple of watts for the microcontroller?)
Do I have some part of that incorrect? I'm basically thinking of one of these AIO's as a big UPS, but I'm trying to figure out what the various vampire draws for the system would be. (In reality I'm just trying to learn how all this works... but this seems like a use case I can wrap my brain around...)
