@RyDawg@mstdn.ca To be a whole-home backup, you need a way to recreate split-phase 240. The charge port can't do that (it can only send either 120 or 240) so to provide that particular functionality, you would indeed need an offboard inverter and in that case you might as well give it access to the battery pack's DC.
In theory, though, this could provide 48A at 120V which would make it quite a capable generator. It just won't be able to power any big stuff like central air.

@TechConnectify@mas.to @RyDawg@mstdn.ca Could you use the 240V and an autotransformer to generate the split phase? Like this - https://www.victronenergy.com/autotransformers/autotransformers ? (see the diagrams in the datasheet). Although I guess the 240V mode might be 50 Hz for Europe, Australia etc. so that could cause some problems?
