Hello
we have a lot of PAE series magnum inverters out there.
One client lately has been experiencing voltage drop and failure of PCBs in two
of his household appliances. I know it’s common to have some dimming of the
lights when a well pump or other large load kicks on, but has anyone ran
Hello Wrenches,
I've got a customer that has an issue with their ~10 yr old SB8000US
connected to a quad stack of Sunny Island system that's off-grid.
It looks like it's on and off, trying to make power but seems to think
there is a problem on the AC side. Do you have any advice as to what may
Mac,
SMA tech support told me this usually indicates a failing transformer so as
Marco suggests, the patient does not have long to live. I've seen a couple
of these at 10+ years of service on the inverter.
Was kind of regards

Long runs of URD direct buried? Just a nick into the metal can corrode
the cable all the way through over time. We use conduit for almost
everything anymore. The savings with URD doesn't pan out, when you have
to abandon the line after 10 years.

Hey Mac,
It’s been my experience over the years that the Imax failure is fatal.

I would look at connections first, lug that is not as tight as it ne we do
to be, a breaker failing, outlets that are either push in wires or have
loose connections. Eliminate what you can before looking at the inverters

I was troubleshooting a site on Friday with the same Imax error on the same
SB8000 inverter. Took the cover off and found a cracked capacitor.
Inverter was manufactured 12/2021 and SMA is telling me it’s out of warranty
(by a week). I’m
trying to appeal to their humanity.
Good luck!
AC coupled off grid? Sounds like a good time to go DC coupled.
