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!

Would agree with most of the post but would make the following points:
- Pure Sine Wave inverters (which the OP is using) are usually of much higher quality than modified sine wave inverters and I've yet to come accross one that works in "anti-phase" as you describe, so they should be okay with RCD's, but as you say best to test.
- Ground Earthing spikes for generators are usually used when domestic wiring is connected to them (i.e. building or portacabin) and is there for equipotential bonding.
