Was the inverter connected at the time of testing?

[RE-wrenches] Just getting old?
Wrenches, I've got a call from a customer that said their (my install) 17 year old GT system went dead. Basic stats: 23, Mitsubishi PVMF120EC3, label says V mpp= 17.6V and Voc = 22 V; top-of-pole; SMA SB3800U. Its one string of 23 PVs. Full sun, 75 degrees ambient during testing. When I checked DC voltage at the inverter landings I got ~23-29 volts (fluctuating) same at the input side of the DC switch. These panels have the old gasketted 4-screw covered J-boxes and screw terminals inside, I removed the covers from three panels and got 9.5 volts at the each of the panels' screw terminals, all the wiring outside the boxes checks out. The system had been functioning normally 3 weeks prior. I could check voltage at more panels I guess. Ideas?

Re: [RE-wrenches] Retail price lists
I won't disclose my markup, but I can tell you that I stopped showing itemized prices on my bids years ago for exactly this reason. The customer only sees the final bid amount. If they want to shop around and buy it on their own, they will have to self install or find another installer. Just my $.02 Shine On!
