My camper has a 12/50 Phoenix VE.Direct inverter with an attached Bluetooth dongle. The 230v output goes to a single gang RCD socket via an auto relay, which switches from the inverter to the EHU when shore power is connected.
I have tried connecting the earth and neutral internally (moving the earth spade terminal in the inverter) and externally (at the relay and in the RCD socket and not necessarily at the same time), in order to obtain the correct neutral earth requirements on a socket tester, and so that the RCD will hopefully work.
If I don't join the earth and neutral, the socket tester shows that there is no earth which is not good and would probably mean that the RCD won't work as it's supposed to (although it tests okay whether the earth and neutral are joined or not).
However, in eco mode with earth and neutral joined, the inverter starts inverting and shows a load of approximately 12VA and regardless of whether or not there is a plug in the 230v output.
When I tried resetting everything to default settings via the app, the inverter started "searching" for about 2 minutes and I thought it had sorted itself out, but alas, it then went back to inverting. I have tried changing a number of the settings, but it has made no difference. Without joining earth and neutral, eco mode works fine.
I think that I either have some settings wrong or there is a defect with the inverter which would not be good as the unit is brand new.
Can anyone offer any advice as to how to sort this or come across this issue before?
Thanks
