While the details aren't completely right, that sounds like Spellbinder (1995).

An accident involving high voltage sends the male teenage protagonist to an alternate world that is pre-industrial, but relics of older and more advanced civilization still existed, like special suits of armor that fired bolts of electricity. He does meet a local girl, but I can't remember the details well enough to say if there was a courtship misunderstanding or not.

I think an eclipse occurred in an early episode and the locals had a primitive explanation for it. Based on that, it seems likely he tried to explain the solar system at some point.

It was an Australian/Polish production.
