Interesting question, in the case that the unit is being fed through the inverter, and an earth fault occurs between Neutral and Earth, then the AC feed side ELU will trip, then the interesting part happens, the inverter will now switch on and supply the load with power. So effectively no earth fault trip.
Now the second scenario, if there is a Live to earth fault, then the AC feed side ELU will trip, the Inverter powers the load, and depending on the severity of the Live Earth fault, the inverter may or may not trip on an overload condition.

NOT SAFE!

So again here is the situation, if you provide the ELU safety on the output side of the inverter, then you are way more expensive than the next fellow who does not care, but sells and makes the sale because he is cheaper.

Go figure.
Cost trumps safety to most customers who have no understanding of electricity.
