Alter is Isuzu 160 or 180 I think

If you arrange the terminals on the busbar so the inverter and battery bank connection share a stud, then the current between these won't need to pass through the busbar, only the terminals. Its possible that during heavy inverter use with the engine on, the alternator might pass its full current, and that would be on a separate stuf - so the current will traverse the bus bar. So, rate the busbar the same current capacity as the alternator.

500 amp capable busbar and isolator to be on the safe side. Make sure the isolators rating is for continuous use. Suggestions below.

Pauls idea is good (can't give greenies to mods)

 

Will the inverter/combi need a fuse though?

 

If so might help to have a midi/mega fuse box as mentioned here:
