It may be that the 60hz GFCI needs to be a 50hz GFCI. I'm going to try that next...if I can find out here in Malaysia.

G-N jumper: if your inverter/charger is a 120V model then you need that jumper. The reason that I don’t have it is that the output of my isolation transformer is 240V and becomes L1 & L2 without a Neutral. So my inverter/charger is a 230V model, configured for 240V 60Hz with ground relay disabled. After that, a new Neutral and 120-0-120
service is created with an auto transformer.
When exactly does your ELCI trigger? If you connect the boat to the ELCI or when you connect
shore power to the isolation transformer? Also, what is the mA rating of the ELCI?
It does not have to do with frequency: the ELCI triggers when the
current between L and N differs more than the mA rating of the device. It’s test button connects a resistor between L and G causing a
current larger than that mA rating to flow so that it should trigger.
