Be careful with RCDs on inverters, some inverters run two phases of 110v making 230 across phases, this works most domestic electrical appliances and lights without problem.
Your RCD may require 230v on the phase to work correctly, only way to be sure is to use an RCD tester when the installation is running on invertor.
Similarly your overload device needs to disconnect at below peak current of the inverter, otherwise a fault may not pull the mcb...
Some use an earth stake with a generator but I don't think there would be any reason to in your case.
It's a can of worms using mains/inverters on mobiles!
