Leisure Vehicle.

Zoomup

Is it realistically possible to run a small 240 Volt microwave oven from a 12 Volt static inverter in a camper van? The leisure batttery is a 110Ahr capacity.

    The leisure battery might be separate from the vehicle starter battery (caravan style, although either option is possible for a campervan), In any event you usually don't want to discharge a lead acid below 50% if you're going to get a decent life out of it - so perhaps think more in terms of a maximum capacity of 660Wh rather than 1.3kWh - and reduced again for the high discharge rate.

    Indeed, the motor starting "traction battery" is separate from the leisure battery.  There is though a battery charger hidden under the driver's seat that supposedly charges the leisure battery when the engine is running. The vehicle had a gas fridge. At first glance the battery charger looked to me to be an inverter. It has the same finned case and appearance. I think the  new owners of the camper van want to live "at home" with all mod cons whilst driving about. That is until reality kicks in.

    Often a DC-DC converter yes., In the old days the leisure battery was just connected across the ignition circut to charge it but that often confuses modern engine management systems as they then think that the main traction battery isn't charging as it should....

    Not sure about motorcaravans but with towing caravans there's normally a 'habitation relay' too - that switches off all the caravan's circuits when the ignition is on (but allows the leisure battery to charge from the traction battery/alternator and the fridge to run on 12V from the traction system) - the idea being that stuff in the caravan can't then interferre with the engine operation.
