Title: Re: [pvusers] PV inverter
reliability
Hello PV users,
I've installed and serviced scores of inverters over the years.
In general your statement is not exactly true. It depends on the
inverter.
Trace SW inverters have an excellent record and have proven the
workhorse of the off-grid industry. Thier DR line also is highly
reliable as is the Tiger series and the older U series. The old
Heart inverters also were a workhorse for many years with low call
backs.
Sunny Boy inverters have over 100 MWatts now installed in Europe
and a 8 year track record there with a very low failure rate.
Trace is having problems with the SunTie line and that may be
where you are hearing problems. Advanced Energy is also having
some problems with their GC-1000 series and still working the bugs out
of their new MM series. Those may be another source of what you have
heard.
It also depends on the installation. Inverters need to be
well ventilated to be happy.
Hope that helps!

I heard that PV inverter
reliability is not good. i.e they fail within five
years.
Is it true?. Is so, PV will not be a successful one
considering the high investment cost.
Does anybody - any PV owner have experience with PV
inverter failure? What is
the actual failed component? Inverter or the PV
module? What is the issue?
Please share your experience (anything you know). It
will be very valuable to the PV community.
Subu./
