How do I wire this A/V Meter inline With Renogy Panels?
#1
The Amp/Volt meter has 3 thick wires, yellow, red, black and 2 thin wires red, black.  I assume
you'd put the thick yellow sensor+thick red+thin red into the (+) of the panels and the
thin black+thick black into the (-) of the panels (along with the solar panel
wires, of course).  Is this correct?

What do you want to measure? I would not put anything between my panels and charge controller. Do you have a manual or instruction sheet with the meter? How about a link to the meter so we can read about it?

It's a cheap a/v from eBay, there's no instructions with it.
I apologize I think I double-posted this I'll try to delete the other.

It looks like there is a sticker on the end of the unit.  That might help.

Just guessing here:
The voltmeter end red to panel plus, black to panel minus.
For the amp meter end, red to panel plus, black to panel minus, yellow to controller panel minus input.  Panel current goes black to yellow.  To convince yourself  measure ohms from black to yellow.  If it is less than 1 ohm that's where the current is sensed and goes from panel minus to controller minus input.
Say good night, Dick.

I wouldn't just guess on this as a mistake could be bad!

Give us a link to the meter you purchased. I'd be glad to look it up and explain based on the actual meter you have.

Many of them are a 5 wire design, yet only 4 are used.

Is your solar panel more than 40 watts?  The amazon ad indicates that it is only a 2 amp meter.

The picture you posted shows two parts, the meter and a shunt resistor.  How many pieces do you have?

there are three choices the 2A version has a built in shunt. the 100A version requires an external shunt. I didn't look at the 10A. the wire diagram looks pretty straight forward to me. highdesertranger

I'm proud of you, that it looks straight forward to you!  I'm not even sure I even bought the right parameter a/v meter now -- to be sure I'm going to ask an EE friend.  At least I have the panels installed up top, rainproofed the holes and ran the wires, that was a pretty harsh job right there (for me).

I don't think that meter will do much for you.
