Isolated Battery Bank?

[Juliet 15]

So, last year I created a new house battery bank. I installed a separate pair of busses (one neg and one pos). The bank goes to an inverter that's wired into the house AC system.

I haven't connected anything but the inverter to the bonding system. Do I need to connect the house bank negative (ground) to the bonding system?

Yes.

what/how did you connect inverter to bonding system, basically the negative of the battery to the chassis. The battery negative should already be connected to the bonding.
