General grid-tie informational posts/stickies?

It may be quite obvious and just common sense to all of you who have been dealing with this stuff for years...but there is no need to mock me.
Thank you sensij, your answer was quite helpful

sorry, not trying too mock you, but to shed light on the solar requirements. On every project, there are thousands of things that are not directly related to the subject. I only listed the relative issues in the first post, leaving the rest to be personal responsibility. I would think that being up 20' on a sloped roof, you have already tied your shoelaces and put on clean underwear.

The problem in the modern world, is there is too much mollycoddling going on, and children are so cocooned and protected, they have never experienced a hammer, let alone hitting their thumb with it. I'm an old fart and take the basic safety stuff as a given.

batteries not included.

+1. I think you covered just about everything.

I think you hit the nail on the head!

He did give a good bullet point list but forgot about "try not to fall off the roof" and "don't get electrocuted while wiring the panels".

That does sound pretty straightforward....what is the purpose of the disconnect switch?

Short answer - code requirement. More obvious answer: The on/off switch for the sun is inaccessible to all except Montgomery Burns. If you, or anyone else, needs to service the inverter during the day, you'll need a way to disconnect the DC voltage generated by the panels.

Mike, that was a masterful "in a nutshell" post.

Grid Tie used to be as simple as it gets. But now new codes have complicated it some in different areas.

Mount the panels on something
Wire them to a disconnect switch
Wire the switch to the GT inverter
Wire the inverter to your electrical panel. (may need to be upgraded)

Depending on permit requirements in your city, you can buy parts, get roof load calculations signed by engineer, and install and wire yourself. Or you may need lic electrician to do the wiring.

Or you may go the micro-inverter route, and put the electronics up with the panels.

Hey guys, I'm looking at setting up some grid-tie systems soon, and I need the 101 on setup and getting them functioning properly. Are there some good resources you could point me to so I can educate myself on the subject? Thanks.
