Can You Invert Sugar Using Heating Elements ? ? ?

[Salt Must Flow]

Can sugar be inverted using internal heating elements without scorching? I have 15.5 gal keg/keggle/kettle with two Dernord 240V 5500W wavy, fold-back elements each with their own Auber DSPR400 controller. I can control the power to each element by 1% increments. I've searched the site, online and haven't found any direct sources, only second hand sources that say it's been done as long as each element's power is reduced starting at 30% and may be increased up to 50% along with agitation or using RIMS with pump.

I used to invert my sugar over propane heat prior to making sugar washes. I stopped inverting the sugar because it was inconvenient and refilling propane tanks was a pain in the ass. I've read that Invertase (an enzyme) can be used to invert sugar without heat (takes 1-2 days depending on how much is used), but I haven't found a source that's priced well enough to give it a try.
