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.

Hi all and thanks for the input.
I guess he’s just been unlucky with the problems ( firmware upgrade
switching to 50hz) and possibly just some random bad hardware.
In regards to your thoughts of a install issue, he has spent a lot of
time with sol ark reviewing everything. Loads, wiring, they have been
monitoring all the data, photos, video etc with everything coming up
correctly installed, wired, and loads.
this system is an upgrade for an older XW ( 6kw units) system which
worked fine. The customer wanted better monitoring, more kw, expansion
capabilities and newer tech.

We have dozens of Solark based installs and have had excellent
results. All of our system have multiple parallel Solark inverters
and have operated with out issues. On the rare occasion that we had
commissioning questions our experience with Solark technical support
has been outstanding, they have by far the best technical support in
the industry. Although Solark helped design the 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 gets a fresh set of eyes on the system and look for that
oversite we have all made and just can’t seem to see it on our own.

Solark issues, I have them living off grid, 3 phase and grid tied
back up, both AC and DC coupled with only one intermittent comms
issue, does not seem to have any more issues than OB and less
than Schnieder, all are connected to Fortress 18.5's or Blue Planet
BMS interface seems hardy,
Would be good to know what issues he is having to accurately help

Hi All,
I’ve got a question about how many folks are having issues with
sol-ark products?
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.
he’s got 2 systems each on is a stacked pair of 12kw units, both
offgrid.
each system was designed by sol-ark, meaning the design was
approved by them for the loads/solar etc.
He’s been through 7 MCU swaps.
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.
He had an inverter that didn’t work correctly out of the box.
They charged him $2500 deposit for a replacement.
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.
Hes not going to pay but this $1500 has been going on a while.
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…...
And the list goes on.
But Im asking, is this poor guy just an anomaly or will anyone
else chime in about issues?,
Because at this point I have no desire to install one given his
experiences
Jay
