an unusual charging problem
Hi all, I'm generator charging from need for the first time in my life. It is not hot enough to run the roof air. Here is a bit about the system. Magnum 3000 Hybrid 12 volt to 120 volt with A...

Contrary to popular belief, auto transformers, being a single winding doesn't boost low voltage conditions. They are merely designed to be connected directly to the single winding with a center tap (or anywhere between extreme ends of the winding) depending on what output you would expect at the load end.
In order to boost the voltage, you would need a buck/boost transformer which is basically a two-winding transformer with primary and secondary windings. Some manufacturers sell a product they call autoformer which hasn't gained any traction especially who are familiar with transformers.
Besides,NEC (National Electrical Code) forbids autotransformers in RVs because of potential over voltage if a winding is open (burned portion of the coil).
