How to AC charge and use AC outputs on an Ecoflow Delta Pro

[Shepherd]

I am stuck on neutral ground bonding. I want to charge my Delta Pro from my house when there is no solar AND at the same time use the AC from the Delta Pro to power a single circuit from my home electrical panel to send AC out to my computer and router. From what I see, having it charge and output AC with them both having a neutral ground bond in the panel will cause problems with the unit. I'm going to essentially just backfeed the single circuit in the panel with an extension cord. Remove the wire from the circuit breaker and wire nut the hot wires together and put the neutral on the neutral bar in the panel. But the neutral bar is bonded to ground. How can I make this work?
