Say you have a Sol-Ark 15K doing 200amp pass-through from the grid to your 200amp main panel. Say you've got a battery backup system hooked up to it. And say you are charging your EV at, e.g., 7.2 kW.
Because the 15K is doing pass-through to the entire panel rather than to a critical loads panel, if the grid goes down, your batteries will automatically takeover and continue to charge your EV at 7.2 kW, correct?
I had been thinking that the Sol-Ark 15K and 200amp pass through, without the need for a critical loads subpanel, would be good. But now that I realize that a grid outage would cause my batteries to be supplying power to literally any load in my panel that happens to be running when the grid goes down (electric dryer, EV charger, etc.), I'm starting to think I might actually prefer a critical loads subpanel. I don't think my batteries would even have the power to power, for example, an EV and a dryer at the same time, but even if they had sufficient power, I don't want my EV and my dryer to immediately drain my batteries during a grid outage...
Am I thinking about this correctly, or am I missing something?
