The majority of 230v consumer units supply 12v to the battery to keep it charged and your lights would function off that and therefore use your battery as their power source, the battery can be recharged using solar (as you found) or by using the consumer unit + charger (you can usually hear that running as it has a cooling fan built in for when it functions.
Your 230v supply is obviously working as the fridge would run off the supply, the lights would NEVER run off 230v unless you have separate 230v supply lights.
The 230v will also supply power sockets in the MH for such things as hairdryers etc. Most MH TV's use 12 v supply rather than 230v. You can also run a water heater off 230v to save gas.
You have demonstrated how little you need the 230v supply so that opens up a vast number of new possibilities for overnight stps (wild camping in remote places).
Hope that makes things clear, there will NOT be a changeover switch as the supply to the lights remains the same - the 12v battery.
Thinking of; Mavis, Ray, Sandra and Albert at this time.
Any comments above are only MY OPINION
and should be read as that.
