Wow. Great price. Thanks.

It does, but you just turned your induction cooktop into a standard resistive electric heating device. Except, very inefficient-and slow, plus can harm the induction element if you try to get it to work as fast as you are used to with induction. (Don’t ask how I know!)

We have had induction at home for many years, best pans are debuyer steel (IMO).

Don’t have it on the boat yet.

It may or may not be relevant to the OP's experiment, but it sure is relevant to me. Mains is not an option for me, so I am always keen to know how people are powering these things.

My electrical setup may be very close to being capable of running an induction cooker so if a small amount of extra capacity will get me over the line I would happily ditch the gas bottle on the stern.

I like grilled cheese on toast to much to give up my gas grill.

The SUMMIT US branded used in some restaurants for fast heating. They have a two burner unit the SINC2B120 at 325 $US that is designed as a portable or a counter top mount. My concern is it can draw 20A at 115 VAC on high. I am also trying to eliminate vapor gases from the vessel. Since I don't know anyone with the Summit I probably will have to be the Ginnie Pig.

Mine's a Midea. I bought it locally in Port Moresby.

Similar, but not identical to this one:


https://us.midea.com/product/Small-A...duction-Cooker


That one is 1500W, mine (MD-STW2020) IS 2000w.

I too am impressed with the induction cooktop. also, I purchased one stovetop, from Aldi as an experiment, since I’m researching the best value for money inverter about 2500 watt. I conducted my test with mains 240-volt power. I Have been very impressive I heat packaged soup in about 1.5 mins at 900 watts when on boil 30 sec, I reduced heat to 600 watts about a 1 min. Note this was a single-serve heated in a single-serve pot.

I see the potential to get rid of my kero stove and gas camper stove for use when moored - With an induction cooktop; Q), Is there an induction oven on the market I could only find Cook tops

As am about to try to install an Induction cooking on my boat, I have upgraded solar panels to 720 watts, and a new AGM battery bank House is 4 x 215 Ah = 860 Ah. 12-volt system.

Now I’m seeking an inverter solution for marine use, the question is which one? This is unless there is a 12-volt induction Cooktop or cooktop oven that someone can recommend?

I like to understand why the high cost of inverter brand like Victron (Very expensive) to same wattage inverters used in campervans and cars that are a 1/4th of the price of The Victron inverters. It seems you could burn out 4 inverters for the price of one Victron unit?
Does anyone have a recommendation which inverter I should install around 2500 to 3000 watts?

We use nearly all solar for power generation via a 2500w inverter. Here’s some figures from last night generated for another thread:

Cook three fried eggs medium setting for five minutes: 2Ah

One fried steak on high for 5 minutes: 4Ah (would have been the same for two steaks)

Off subject: Nespresso machine used for 1 cup of coffee: .4Ah

I'd wonder about doing it the OTHER way - what happens if you put a steel plate INSIDE the aluminum pan? That way you're not relying on conduction to move the heat from outside the pan to inside.

Obviously, it depends on what you're cooking and it'll be an extra thing to clean up, but I'd suspect it will work better than the other way around as far as the actual heating goes.

Yeah, you can buy them with handles for that purpose at Amazon.

The 1300W unit I ordered from Amazon had arrived when I got home from work just now. $69 including a skillet.

Those diffuser plates work fine. They have nice handles and will allow the use of almost any pot with an induction stove. Cast iron cookware is inexpensive, virtually bombproof and work fine with induction. The flatter the bottom the better.

Since I am in the process of researching this I can tell you 2 things about the power source:
A. Needs to be a Pure Sine Wave inverter. Some will work with MSW inverters, some will kinda work and some pairs won’t work at all.
B. When the induction comes on some/most/all initially start at full power in order to sense the coupling to the pot and maybe to have a surge of heat to bring the active part up to temp faster. That means you probably don’t want to skimp on inverter capacity by thinking you’ll never turn it up to full power so you can get away with a 1500W inverter pushing an 1800w hotplate.

I’m going to be testing this this weekend. If I remember I’ll post here.

Induction has no advantage over resistive heating for an oven. Both heat the air to completely surround the food and cook from all sides.

For boat use a small toaster oven may be sufficiently efficient, especially it you can insulate the box. Another option is a Convection oven. I’ll get to testing the oven options eventually.

Look at a Magnum, what drove me mostly to them was I’ve not heard of anyone having a failure, but if they did, the cards are easily trouble shot and relatively inexpensive.

If it’s low power usage your after look real hard at a micro convection, most stuff you cook in an oven will be cooked by microwave, the convection side browns of course.
The Sears one we had many years ago plugged into a regular 110V outlet of course, but would cook a Thanksgiving turkey in about 2 hours, where a regular oven drew at least twice as much power and took many hours longer.
