There's a ground on the inverter, so I thought I should use it - if not doing so won't lead to the end of the world then that's good news.

System is going to be (currently all ordered):
120w solar panel>Victron MPPT 75/10 solar charge controller>Renegy 50ah LiFePo4 battery>Victron Smart battery protect>Victron Phoenix 12/250 Inverter>Hormann Promatic garage door operator.

According to the manual it's not connected to anything other than the inverter housing. It's there because in some configurations you might connect one of the AC output wires to it to create a neutral, but that's a whole can of RCD-requiring worms.

Without checking the manual, I would say it is acting like an isolation transformer because the earth is not tied to ground. It is theoretically safer because the output voltage is floating and not referenced to true earth.
