All good points and I am well versed in the arithmetic involved with batteries and inverters. This Prevost, like many current high end coaches, is an all electric coach with 1850 ah of AGM batteries. All the appliances are residential devices. There is no propane on board although I do carry a small bottle to power the propane fire pit and the BBQ.
The appeal of induction cooktops, and why they are common on new coaches, is they heat food very quickly while imparting far less heat into the interior of the coach so it stays cool unlike cooking with propane or resistance. Those same traits are why they are so popular in other countries around the world and are becoming more common in residential applications here as well.
The fast cooking means the inverter, while drawing substantial power, only does do for a short period of time - a few minutes for most applications. Very much the same arithmetic as powering a microwave from an inverter which
many motorhomer's do from far smaller battery
banks.
Yes, turning on the 17500 watt generator is an option, and what I would do for extended cooking applications, but I also want to explore the inverter option for quick use. Hence looking for anyone who has experience doing so.
Thanks for the input.

Hi John,
I am usually a lurker on GMCnet and only pipe up occasionally. I, too, am interested in the reasoning behind using any electrical cooking method in a GMC be it inductive or resistive - but even more so I was wondering why one would even consider running it from an inverter.
Like solar panels and wind turbines, these inverters seem to have some magical Star Wars light-saber allure and end up getting used for all the wrong reasons. Unfortunately the EE concepts of P=IE and P=I^2R (re conductor loss) are usually ignored on the inverter setups and result in installations that are either marginal in performance or are outright dangerous.
I guess if one has an unlimited supply of DC then drawing 12V @ 200 amps for a half hour while cooking dinner is OK..but why not just use propane? Or, if you really must have electrical cooking - start the genset for a bit?
Sign me ?baffled?...
