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?...

Hi Jerry I am an ex truck driver and have used inverters of every size to
power my 110v stuff I went to 110 after going through loads of 12v things
got tired of burning up coffee pots the inverter opened up a whole new
world with me living on the road when my wife and me saw the advertisement
for the NU WAVE induction cook top I thought this would work great so we
got the deal for two of them when we got them we tried it at home and it
works like a dream but when I put the other one on the truck it would not
work so I got a bigger inverter still nothing I then got the other one from
home and tried it still nothing so I called the company and asked them
about it and was told that because of the way they are made that they will
not work with inverters the nu wave is only1300 watts and I was pushing it
with 2500 and 3000 watt inverters so it must be something with the circuitry

Hey Jerry,

Just wanted to drop in and give a big thank you to you and your wife for being such gracious hosts while we conducted our business. I ended up taking the coach up through the Olympic Peninsula, then headed east through Washington all the way to Montana before heading back south to Nevada. It never let me down, and I had a great first trip roving around the west.

I’ll be taking it east on my next trip, probably to one of my favorite areas (The Great Smoky Mountains of Tenn and the western mountains of NC). From there who knows, may even spend some time down south in FL.

I hope your trip to Europe went well, and that you and your wife are both living it up.

Hello to all veteran and new GMC’rs. I constantly lurk the email chain in hopes of picking up a bit of knowledge, as right now calling myself a rookie might be more credit than I deserve. It makes for interesting reading regardless.

It's the waveform put out by most inverters that causes the problem. An
induction cooktop induces electrical currents in the metal of the pan, and
the electromagnetic field it creates to do that requires a clean sine wave,
so that currents and voltages are constantly and smoothly changing rather
than jumping in steps. It should work with a true sine-wave inverter. That
would let out my generator, which uses a dedicated inverter that is
probably not a sufficiently pure sine wave.

An apology before the start. The below has a lot of things that non-E-freindly people may not get. The problem is that I don't know other ways to describe some things. If you can form a specific question in normal English, I will do my best to answer it, but that may take so doing.

Until the depression shut us down, I earned a lot of money converting racing sloops to performance cruisers. This involved mainly three things, comfortable living spaces, workable house electrics and civilized plumbing. These are all things that are absent on race ready boats. The comfortable living spaces was largely plywood cut to shape, tabbed in and then a final assembly with screws into cleats, the civilized plumbing was always to include H&C pressure water in both the galley and the head. Adding a shower was difficult and expensive as zero discharge made things tough. The house electrics was always a big thing because owner never envisioned the complications.

The occasion of running microwaves and a few other things from an inverter was always an issue such that I began to refuse to write a quote to do it. Anything that used the juice for direct heat or to run a real motor was never any problem, but anything else was an open issue. The real unexpected gotchya was a color laser printer that the owner needed for business. That would sort of work, but it would periodically go crazy. There was no indication of why except that it was flawless on shore power. Nothing could tell me what the problem was. Then I put it on a split (that allowed me access to the individual conductors) and watched the current with a Bell probe. These are an analog device with effectively high frequency response. When watching the current with my 87, the flying spot would periodically jump. The numeric display would maybe shuffle a last digit. So, I borrowed a little digital O-scope and looked again. At first it looked good, then it looked like nothing and then it was ragged again as the digital signal aliased in and out of sync with the scope. Then (from the same tech collector), I borrowed a an old glass Tecktonics. Completely Analog. It showed me that the power consumption of the printer was all over the place when it tried to run from the inverter because the two were close to the same switching frequency. I have forgotten the actual model but the inverter was supposed to be a pure sine. Needless to say, it really was not it was just better than the modified square wave versions. The glass scope confirmed that. It looked pretty good until one expanded the wave form. It was only a close approximation to a sine with big steps at both ends where it zero switched.

Do I have an answer?
Sorry, I don't. I never saw the issue with the old Heart inverters that had an iron core transformer and a 1.5KVA was most 50# or a rotating machine that runs a synchronous speed. So I would guess that those are your choices if you want fancy electronics to work reliably.

You can buy an inverter which does in fact produce a good sine wave. Actually, if you look at the Onan waveform, it gets up around 5 - 10% distortion when it's heavily loaded. Be sitting down when you see what such an inverter is going to cost you. If it's producing a true sine wave, not something assembled fro a bunch of steps, it doesn't matter what speed the power supply switches. The estimate price of Peer's propane conversion to German spec might buy one.
I have an old UPS which came out of a transmitter plane when we upgraded to run the whole place sans utility power. This thing kept some of the computers alive until the genset took load and restarted the transmitters. I put a 35KVA 3 phase UPS in place with about 6 - 7 minutes of batteries which was more than enough to start the genset. It actually made a better waveform that Ga Power at the location. I run the little one off the house batteries if I need 5 minutes of A/C for something. One outlet, suitable for my soldering gun or iron or the like.

I wonder if an isolation transformer in 2 in series would kill the
high-frequency component filling in the gaps of the switching inverter. The
key would be to have energy stored in the iron core.

A good line conditioner should be able to convert a modified sine inverter
to a good pure sine inverter.
After thinking about it I would try a unit like
https://www.zoro.com/tripp-lite-power-conditioner-small-tower-18kva-lc-1800/i/G2208823/#tech-specs
and see how it works before I invested in inverter shopping looking for
just the one that works.

The inverter in this small generator powers the NuWave induction cooktop. I wish I could use it to power the roof A/C and leave Onan at home.

I was trying to ask a similar question on Facebook a couple of weeks ago,
but i think I just confused everyone. What about using two of those small
generators on for your induction cooktop and one for your AC?

I wasn't even dreaming of using both A/C and cooktop at the same time from any inverter I could afford. I could connect 2 of those units and probably run a good A/C unit with some lighter duty components than the 44 year old unit up there now, which cools great but takes too much current to start the compressor. I really need a new roof A/C unit that would start and run on the small and quiet inverter generator. Then of course have to get one with electric start...didn't see a good way to take the 3500 from HF apart.
