efficient solar stovetop compared to induction cooktop

Hi, was wondering if anyone has used a microinverter just for a single AC appliance, which would be an induction cooktop. Also, if there are other stoves that work with DC hookups to solar panels. I'm interested in an all-DC system, though if the cost of an inverter, batteries, panels plus the lost efficiency from DC-AC is less than the efficiency gained from the faster cooking of the induction, compared to a gas or wood stove or something.

Yes! You can use an AC Induction cooker with solar offgrid system with an DC-AC Inverte with Transformer and Pure Sine Wave cycle. You need an Inverter with minimum 220-240V AC 0ut of 2000-3000W. There are Induction cookers from 800-2000w so the best solution with solar operation you must choose one of the Induction cooker from 800-2000W.

For example: 800w Induction cooker you need following solar components.
1. Solar Panel with 12V/100w or above.
2. Solar Charge Controller.
3. Solar Batteries.
4. Solar Inverter
5. Cable and accessories.
6. Enclouser and Mounting brackets.
Here is some simple calculation of 3 hour operation for your Induction cooker / day with solar power

Solar off-grid 800W
Solar Panel : 800W *1.3*3 = 3120 / 5.5 = 567.27 / 100 = 5.67 @ 6 panels of 12V/ 100w / 5.05A
Solar Charge Controller : 6 * 5.05 = 30.3 A @ 40A
Solar battery : 567.27 @ 600W * 3 = 1200W / 6.12 = 12V/196Ah @ 12V /200 Ah
Inverter : 800W * 30% = 1040W @ 1200 or above ie: 12V DC / 1200W /220 AC /50-60Hz
