I understand basic DC and AC (240v) principals, but within the off-grid setup I have I'm having some questions on how I setup a 'safe' system. I've installed an array, solar charge controller, battery and inverter (240v) AU. I've also installed a grounding rod and have the solar charge controller and inverter all back to a common busbar and that is connected to the earthed rod.
But when I use a plug tester I get an error on the earth connection, as in it doesn't show as an LED to indicate all is working. Now I've watched some YouTube videos and found that it's due to the way the inverter generates 240v power. With a normal AC (Australia household) setup being L+N = 240v, N+L =240v and N+E = 0v, but with an inverter it's L+N = 240v, N+L = 120v and N+E = 120v and thus it'll never have a correct test result.
On the inverter it has 3 output, L, N & E and I've attacted my grounding to that E output connector (only grounding point for the inverter and per contacting supplier).
So my question is, am I protected from an Earthing issue? With the two 120v phases making a single 240v out, is it even possible for me to achieve what I'm trying to do? I've read, and I need to look into more, about ground-neutral bonding, but I'm not sure if I should attempt this or how to go about it.
What is the best way to go about this? Any help appreciated. Here is a photo of the current setup, if that might help.
