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.

at the shallow end, rather than dual alternators

and or diode switching diode example, a simple relay that parallels the auxiliary battery to the cranking one when the latter is at more than 13.5v i.e. pretty much charged is common. However a single car grade alternator may struggle with a flat battery and the loads of a dark winters night, example relay. It also confuses those stop and go systems that cut the engine at traffic lights etc. Fine for doubling up 2 similar batteries but not anything seriously heavily loaded.
