Re: [RE-wrenches] Xantrex AC Fault 186.6v

[Jerry Shafer via RE-wrenches]

The xantrex had one fused line on some of the GT lines,as l recall its a 15
or 20, no this is not the GFI Fuse, old SMA's also had just one.

Re: [RE-wrenches] Xantrex AC Fault 186.6v

[Ron Young via RE-wrenches]

Back in the mid ’90’s one of my businesses used colour laser copiers worth $50k 
each. Located at the end of a long rural route the voltage would whiplash 
through a wild range depending on demand upstream (mostly low voltage). It kept 
blowing the $5,000 lasers out of the copiers until the techs realized the 
problem after installing a data meter. Problem was solved by installing an 
isolating voltage conditioner.

Wrenches
First of all confirm as it might well be the inverter, SMA is a great
solution for a replacement however like much we deal with are in short
supply, if it is a battery inverter then the Solark or Outback are good
solutions.

Re: [RE-wrenches] Xantrex AC Fault 186.6v

[Barton Churchill via RE-wrenches]

I’ve seen services at the end of utility lines have wildly fluctuating voltage, 
especially during high demand winter months. When voltage goes below or above 
inverter set points the inverter will disconnect with a fault like you listed. 
Changing inverters will only help if the new one has a larger voltage window. 
Otherwise get the utility to install a meter for a month or two, if there is a 
problem, they have to fix it. Also, if load side mains are undersized for 
actual load the voltage can drop at the inverter (and everywhere else) causing 
the same thing.

Howdy Wrenches,

Any "old timers" here care to chime in with some basic info on what I might be 
heading out to see at a 10+ year old ground mount?  It's a Xantrex displaying 
the message AC Fault 186.6v.  I'm prepared to head out there and troubleshoot 
blind if no one has anything to offer up but figured why not post a quick 
message here in case anyone has insight they wish to share with me prior to my 
visit next week.

Subsequently since this is a ground mount it doesn't need rapid shutdown so if 
the inverter has failed I probably have some decent options to replace it.  If 
you've had good luck with a particular brand to use for swaps please share that 
intel as well.  I don't know how big the array is so all I'm looking for is 
brands and not models.

Most appreciated,
Sam
