Re: [RE-wrenches] BP HI / Namaka with Sol-ark inverters

[Jeff Clearwater]

We just ordered a 3 Sol-Ark system with 16 Storz Power batteries I'll 
let you know this Spring once I have it up and running.  Yes they are 
closed loop will be UL9540 soon.


We have several Sol-Arks in the field - all working great - yes a few 
minor issues that have required software updates - but tech support is 
great and they push the updates for me.  I love the monitoring and 
ability to remote program every parameter.  Conversion efficiency in all 
modes is high (though slightly under what they claim but still great)


Surge is fine per leg with multiple inverters or a balancing 
transformer.  Gen support could use an upgrade  for sure but they are 
working on it.


The  Time-of -use  features and interface we love as you can really fine 
tune daily cycles - optimizing solar and battery and grid and generator 
inputs - Especially great for grid-tie with strong off-grid capability 
as opposed to most  lightweight GTTB systems.  In pure Off-grid I find 
them robust and reliable so far.


Enjoy!

Is anyone installing Storz? From what I understand, they have closed 
loop comms with Sol-Ark and a very close working relationship between 
manufacturers. I believe all customer support for Storz supplied 
Sol-Arks goes through Storz. They have a special Sol-Ark firmware that 
they maintain.


Maybe users have a better experience with this collaboration.

Eric and Wrenches,

We have come to the same conclusion.  Sol-Ark isn't ready for 
prime-time off-grid.  Too many glitches...


One serious off-grid disadvantage with Sol-Ark is idle consumption.  
It really is much, much higher than older style inverters so it 
needs to be factored into the load analysis.  The spec sheet is not 
accurate.  The firmware is all over the place, many glitches and issues.


I do admire that they are diving into the battery communication arena 
but voltage control works quite well.  If a system can't effectively 
keep power on, do we care if the charging algorithm  is slightly more 
efficient?


My big question, that I've never really understood is why is it so 
hard to standardize battery communication?  Isn't CanBus, Modbus and 
RS-485 a standard?  Doesn't that mean that it should be easy 
and structured?  I must not really get it...

 Hi All,

 I am considering changing the inverters on several Blue ion HI LFP
 storage systems I'm installing this Spring from Outback Radians to Sol-Ark.
 I have no experience w/ Sol-Ark, but it seems more advanced than the
 Radian. I'm wondering if Sol-Ark and the BI Namaka gateway/monitor can
 directly interface as Namaka can with some inverter brands. And I'd be
 interested in hearing of any experiences you may have as to how nicely
 these different components play together. Thanks.

Re: [RE-wrenches] BP HI / Namaka with Sol-ark inverters

[Kirk Herander]

Thanks for all the comments folks. To add complexity to this subject, one
of my projects is a small BI HI storage upgrade (offgrid), the other is a
500kwh BI HI bank, using multiple Radians or Sol-arks which will be
AC-coupled with several string inverters. I'm leaning back to the Radians,
at least for the big system.

Re: [RE-wrenches] BP HI / Namaka with Sol-ark inverters

[Eric Smiley]

Kirk
We tried using SolArk for off- grid applications but stopped for several
reasons:
- surge on single phase loads
- too many firmware updates  (i.e. bugs in the firmware or new features
that are standard in other inverters)
- too many service calls: false positive arc faults, AGS not working,
battery over charging,..
- not modular. If one component has an error, it can take out the whole
system.
- too reliant on an internet connection
- hidden settings that aren't described in the manual - including one that
could only be accessed via the internet and left a customer without AGS for
several months until they hooked up their satellite internet. We thought we
were going to have to replace the inverter.

We've gone back to equipment that does less and has a longer track record;
so we don't feel like we're beta testing equipment with our clients and we
know what the limitations are.
Tech support has been great and the monitoring is quite good. It just
hasn't been reliable enough for full time offgrid.

When we compare the service calls for our Magnum, Outback, Conext, Trace
(yes we still have two SW systems going strong) and SolArk systems, the
initial savings with SokArk disappear. I can't recall the last time I had
to repair/service a Magnum system unless it was user error.
Keep it simple!

Re: [RE-wrenches] BP HI / Namaka with Sol-ark inverters

[Jerry Shafer]

Kirk
You can also connect an outback through the NaMaka and the optics, plus the
Outback has better surge power then the SolArk, We use both Solark and
Outback coupled with the Blue Planet, 2.0 and now the 3.0, Yes solark can
do 3 phase including delta, has high voltage dual PV input, Outback has one
big benefit and that is surge along with being modular from internals to
charge controllers, all separate and serviceable individually
