Battery Cable to pass through

[Funseeker Mike]

I have a 2022 Outback 330RL and was wondering is there a way to connect battery cables to an inverter without drilling a hole to the pass through?
Thank you

Depends on where you plan on mounting the inverter. Some additional info about your intended plans for the inverter might help as well.
I installed our inverter right in the entertainment center since our plan was to primarily run the TV for movies in the evening.
If getting into the passthrough is necessary you might consider coming in from the bottom. Any penetration could then be easily sealed with expanding foam.

I would say no. If the inverter is in the pass through and the batteries are outside. I can't imagine that there are existing cables of the correct gauge to satisfy an inverter of any use/size.
