Solid advice from both Ray and Allan.
Switching to a sine-wave inverter will solve the controller issue, but not the 300W glow bar draining the batteries. Switching to a Peerless-Premier would solve that problem, or use an old Wedgewood range like I do. My 6-burner/two oven gas Wedgewood from the early 40’s works great, and will likely last for centuries, but it does take 4 gorillas to move the damn thing. It must weigh 600 lbs, although I’ve never weighed it.

It's almost certainly the crude waveform that's causing the issues. If range replacement remains the only option, talk with Peerless-Premier ( www.premierrange.com). As of my last contact with them a few years ago, they still make unadvertised models with circuit boards that were designed for original Trace mod-square inverters and have no glow bars for the oven. Our family home has a decent Pro series (stainless front with sealed burners) with electric igniters and no glow bar.

I may just tell them to go to a pilot light stove model (hate to waste gas, ya know).

As soon as I read "control board" and modified sine wave, I cringe. The good old DR inverters worked great, I even ran my own shop on one for several years back in the 90s. I for the most part quit selling them though, as even though most equipment worked on the mod sine, we started noticing premature failures. I would attribute this to the extra heat generated by all the extra harmonic distortion. Sorry I can't recommend an oven; they probably would be better going to something older form Craig's list with no AC connection at all.

The appliance is a Whirlpool Model WFG515S0EW0 powered by a Xantrex DR1512. Since this is an off-grid home, i recommended that they get an LP stove with no oven glow bar and this was the unit that the appliance company supplied. Has anyone seen this before (i am assuming incompatibility of the circuitry with the modified sine wave output)? Can you recommend another model that has been tried and true (preferably Whirlpool)?
