If we assume that this is 5 minutes, then that is 66Ah from your battery... with a 120Ah leisure battery this is already over the 50% of the recommended discharge depth... So point #1 you need to keep the engine on while using it and most likely, with a common 100Watt Peltier element for the cooling it is likely to be pulling around 8Amps even when not microwaving stuff... Not my idea of green living even if it does fit the criteria of off-grid...

It's a cool idea but in actuallity, the thing just doesn't work very well. Did you read the reviews for this microwave? It’s a cool idea but in actuallity, the thing just doesn’t work very well.
