<p>One thing I can say: trouble shooting problems over the phone
has its limitations. I had a customer issue with a system we
hadn't installed that was quite vexing. Turned out to be a loose
main DC connection to the inverter. Bizarre behavior as the
connection heated up and the resistance varied.<br>

questions our experience with Solark technical support has
been outstanding, they have by far the best technical

system in question I suspect that there must be some finer
points that were not shared with Solark, a load side
wiring problem or perhaps an installation error that is
causing the repeated failures. I suggest that your friend

<p class="MsoNormal" style="margin-bottom:12pt">Hi
All,<br>
<br>
I’ve got a question about how many folks are having
issues with sol-ark products?<br>
<br>
the reason i ask is that i’ve got a friend, a good
competent installer ( well versed in OB, Schneider,
magnum) who’s had continuing nightmares with them.<br>
<br>
he’s got 2 systems each on is a stacked pair of 12kw
units, both offgrid.<br>
<br>
each system was designed by sol-ark, meaning the
design was approved by them for the loads/solar etc.<br>
<br>
He’s been through 7 MCU swaps. <br>
He’s been through a field call required because the
over the air firmware update caused the inverters to
go into 50hz and for some reason that isn’t fixable
via the web.<br>
He had an inverter that didn’t work correctly out of
the box. They charged him $2500 deposit for a
replacement.<br>
<br>
Then they charged him $1500 to fix the inverter he
sent back under warranty. Thats right $1500 to fix a
warranty which they agreed was a warranty issue.<br>
Hes not going to pay but this $1500 has been going on
a while. <br>
<br>
The inverter they sent to replace the broken one had a
older MCU firmware so wouldn’t stack and it took tech
support way to long to figure that out then they had
to send him a new MCU…...<br>
<br>
And the list goes on.<br>
<br>
But Im asking, is this poor guy just an anomaly or
will anyone else chime in about issues?,<br>
<br>
Because at this point I have no desire to install one
given his experiences<br>
<br>
Jay<br>
