Earthing connection for inverter install

[leemarkadams]

Hello all, am looking to install a 2000w inverter and in the manual it says to connect the chassis of the inverter to ground.

Looking to put the inverter behind the couch on the stbd side, so any ideas where the best earth connection will be on a hunter legend 41ac?

Thanks in advance

Is your negative buss grounded? If so, I'd run a large gauge wire from your inverter to the negative buss.
