My considered goal is to change to a 2 burner induction stove top and depending upon the reviews and recommendations of actual usage on a boat, replace the current oven with a convection/microwave oven. Granted, I can cook and live with the current configuration of 3 burner Force 10 (Princess was bought out by the Force 10 people) stove and oven plus the standard microwave....
I have a 30 amp boat, a 6KW generator, 2x130watt solar panels and 3x4D (3X200amp) AGM house batteries. (plus another 4D start battery) and a 40amp charger
I have learned successfully learned the very famous, "30amp load shedding/planning and timing dance' successfully, without the boat going dark.
First suggestion: put an AMP meter in the galley so you can watch the increasing AMP demand and make corrections.
#2 shut down the electric water heater, 11 gal. The water will stay hot for at least one "navy shower" and washing dishes. (I also have the main engine coolant set up to heat the hot water.)
#3 rotating the electric burners.... the element will stay hot for a few minutes while shifting to another burner, same with the oven.
#4 I have a 1800 watt inverter, I can put the microwave on it but, microwave oven does suck down the 3 house batteries voltage quickly.
AND if I elect to do all the modifications as stated in the first sentence, I can get one more cupboard.
