Re: [RE-wrenches] sol ark reliability question

[Jeff Clearwater via RE-wrenches]

I have a dozen Sol-Arks In the field and all systems have been giving solid 
performance . The MCU board upgrade is standard and super well supported and 
easy and usually done in a preventative context. I consider that a small price 
to pay for all the Sol-Ark can do and the overall performance and what the 
feature set provides. As others have mentioned best tech support around. The 
Time of Use features are brilliant as are the robust MPPTs and the 
programmability in general allows me to optimize hybrid systems like no other 
inverter I know. For us it has replaced the venerable Sunny Island as our go-to 
for large off-grid systems.

Re: [RE-wrenches] sol ark reliability question

[pieter offgridenterprises.org via RE-wrenches]

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.

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

[RE-wrenches] SMA alternative?

Esteemed Wrenches,

I am a long time fan and installer of SMA string inverters. I have a project 
right now which is a ground mounted array of 12 Trina 380s, so just over 4.5 
kW. 

SMA inverters seem to be unavailable for the foreseeable future. What would be 
your recommendations for an alternative? I know it’s unfashionable, but I’m not 
a fan of micro inverters.

Re: [RE-wrenches] sol ark reliability question

[Mac Lewis via RE-wrenches]

Hi Jay,

Generally, Sol-Ark has been very good to work with for us.  We've done
about a dozen of them.  We did have an MCU swap for a parallel stacking
glitch.  I could tell it was a known issue because the diagnosis was
remote, took about 10 seconds and the shipping was about 2 days and has
fixed the issue.

My only gripe with Sol-Ark is the general weirdness of the generator
integration.  Not really much you can do to adjust or optimize, so this
could be better.  I suspect they will get this better over time.  I would
also like them to work to add a little timing bubble as parameters are
getting updated.  I think its confusing when you can't tell if a parameter
"stuck" or not.  A little visual feedback would be great.

Overall, very good to work with as a company, but Im still getting used to
their tech.

[RE-wrenches] sol ark reliability question

[jay via RE-wrenches]

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
