Am I right in thinking that as I live in Spain so have a reasonable amount of sunshine to keep the solar panel busy, when MH standing idle between trips away, the batteries will be adequately topped up by the solar panel, therefore no need to be hooked up except for possibly the night before we set off again so as to get the fridge cold?
Secondly if I turn off all the electrics via the Battery Circuit Breaker does this affect the batteries being charged by the solar panel?

Living the dream.
1, if your solar charger/battery bank is connected to your starter battery it should get charged up fine.

2, yes I would think so unless the battery isolator is after the solar connection to the battery bank.

Depends whether your solar panels charge both hab and engine batteries.. ?

The battery isolator switch will normally isolate the batteries from everything, so they won't charge from solar .. but that also depends on how the solar was installed, it may go direct to the batteries.

You should be fine and no need to plug in the night before you leave but I'm unsure what effect your battery circuit breaker will have. My suggestion would be turn it off for a few days then measure the battery voltage at the terminals. Then, assuming it's a sunny day, close the circuit breaker and see if the voltage jumps up. If it does this suggests opening the circuit breaker isolates them from the solar charger.
Hopefully it won't! But I think you should have some sort of meter showing battery voltage and if it reads something around 13.8 volts when the sun has been shining for a while this would indicate the charger is working.
