Is this a good deal?

I am in general ready to drop a dime on solar geni. My calculations point to a 400-600watt system with about 400ah total of battery. I came across this on Craigslist and it seems like it could be a decent start for my system.

The panels are almost 5 years and I can only assume the batteries are the same age.

I can test the panels with a multi meter easily enough but I don't know how to test any individual cells.

The Charge Controller:

Aside from attaching to a panel is there some other way to test  this device?

Other than a multimeter is there some way to test the AGM batteries? After 5 years of unknown usage I would assume off the bat that they are pretty well shot.

I will still need to buy wires, fuses, etc etc etc.

Thanks!

First thing.  The price for those panels is way beyond belief.  The manufacturer of them gets $3 a watt. Renogy is getting $2.19 a watt for their new top of the line super panel. $1.39 a watt for a standard panel  NEW DELIVERED.  Less if you buy a kit. 

Second, the controller is undersized for those panels. (360W controller and 560W panels) 

Third.  Batteries.  5 years old.  Those are expensive units, but no telling how they were treated. 

Personaly, I would not take the $1,000 gamble.   ($1,500 set up right.)

OK. Aside from the controller I had come to the same conclusions. I missed that about the wattage ratings.

I offered him $500. Old panels, old batteries, power mismatch on the controller ... we'll see what he says.

I could split the four panels between the ProStar and an EcoWorthy controller that I already have. If I understand correctly this is even a preferred configuration.

With 560w of solar I should be able to charge 400ah of batteries pretty reliably, especially going in to summer.

I'm prepared to buy new. If he bites though, this may be a good cheap alternative. I'll have no reason to do anything other than over engineer the rest of the system as I will not have to spare costs.

Maybe he was running both the panels and batteries in 2S2P. According to Morningstar this unit will handle "PV Input @ 24V 720 Watts".
