Yeah - 5 Ohm is the bit that matters. I’m in the process of installing an off-grid solar energy system at my home, which the previous owner had wired up, ungrounded, with a generator. I am not exactly following code, as my earth comprises a 5 meter RSJ left over from construction buried 30cm down under a dirt road - we have very little soil over bedrock, but the soil is full of iron. It’s only half buried but I’m at 2.2 Ohm, so it should do the job - have soldered a nice fat cable to it to be my common ground.
