I never seen anyone use a 100 ohm resister on that type of Inverter. You would think the Inverter of that complexity would have some protection. Does the Manual advise you do this ?
It won't damage the inverter if you don't. It's just a common practice that people do. Newer rack mount style batteries have pre charge circuits built in but not all batteries have this. If you don't it will create a big spark when connecting battery for first time. If you look around you will see this. Did not see anything in manual about it.
