There is a difference between a switch for the 120v side of an inverter and one for the DC side. The DC side needs to be beefy for the ampacity of the inverter to battery wiring. The DC switch will have different amp ratings for 12v and 24v too.
I have some cheaper DC switches good to 100amps. I noticed that when "open" they still "leak" a little, so that is another thing with switches.
For storage, it seems easier IMO to remove the wires from a battery post.
I already have this switch to completely shut off the power to everything.
Battery Disconnect
If there is a concern about the inverter drawing to much power while shut off I would add another on of these to control power to the inverter.
We do not dry camp but might stop overnight at a rest area to get some sleep. That is where my concern came from the inverter draining battery while power is on but inverter is not being used.
You can use your multi-meter on volts and check each side of the switch when it is open. Might find a small voltage "leak", which would be no better than having the inverter's 120v "off", but still drawing a little. Or that switch might be high quality with no leakage.
