solar pre-wired questions
Our new rv has an outdoor two pin plug-in for solar. What do I need to take advantage of it? What are it's benefits and limitations? We don't currently have any panels.

#10 is a fine size if not overkill. Using an 100 amp Outback FM100 or Magnum PT-100 as an example you could hook up well over 1,000 watts of solar panels.
Sorry, not practical…

What are you talking about? I probably install one of these a month on average.
Nobody doing any serious solar work even thinks about using a charge controller that isn't an MPPT model. PWM controllers are like black and white TVs and floppy disks.
You seem to think that your original answer, about #10 being good for 1000 watts, was sufficient for a new user. Your answer is only correct if the #10 wire is between the solar panels and the controller, and even then, at 40v or above. The new user would not know that. Following your advice and putting 1000 watts at 14v on #10 wire would be a catastrophe for a new user. Also, you assumed that the new user would KNOW to use an MPPT controller. Not a safe assumption.
Yep, thanks Bobbo, that’s what was meant by “not practical”….In fact, in retrospect I thought what I was reading might just have been a typo :h
