Decided to take some current measurements from the Duxtop Model BT-200DZ induction cook top to find out if it pulsated 100% power on and off or actually provided variable power settings. Below are the factory power settings and my results using a clamp meter.
Although I didn't test all 20 settings, starting at 3.0, a lower setting then I would use, indeed the power cycles on and off continuously, I assume lower settings would do the same.
For settings 4.0 up, I tested selected settings for about 2 minutes each while bringing a pot of water to boiling the current did slightly drift but I didn't see any indication of cycling on/off/on. Results indicate the cooktop is not capable of the published 1800w, highest recorded at setpoint 10 is 1452w. Unless I am missing something I don't think using cooktop killed the inverter, and 1500w shouldn't have an issue, perhaps running no higher than power setting 8.0, 1247/1255w (Highest setting ever used was 6.5, 1874/1080w).
Pre-charging.
I need a way to pre-charge not only when home but also if problems arise when traveling so a solar panel, even a very small one is a nogo to carry in a minivan, this is why I am thinking 12v bulb/socket and the method of pre-charging I described in previous post, fits right in my tool kit but need to know if it will work as I described? I've seen posts on this site where some use a #2 pencil but like being able to see the light bulb glow.
