and anything using a EHU shouldn't be exporting power anyway ... given they're connected via plugs that have the pins exposed when disconnected (automatic shutdown on grid loss isn't quite quick/reliable enough to prevent shocks).

Given that most caravans use the mains to re-charge the leisure battery (often the best part of 100Ah) I might be tempted to wonder if a B-type might be sensible to guard against faults between the a.c. and d.c. systems...

Could it be feasible that in the future that caravans static or mobile would have PV on the roof?  What about motor homes?

It's normal to have solar to recharge the 12V battery.  But how many motorhomes would have a grid-tied inverter onboard?

hopefully none with a plug and socket hook up.... (!) the ability to generate and have live pins end of the lead is not a good idea.

Static caravans with permanent wiring might well however.

I suspect the better  holiday tourer may have an inverter, but not driving the same sockets as the shore power directly
