Sol Ark related:

 

– we often get requests for their batteries and there seems to be a shortage at 
the moment and stock will not be available until mid to late Nov.

 

Below a response we received this morning from Sol Ark:

 

Due to the shortage we are trying to make sure batteries are being used with 
Sol-Ark systems. 

This is the only reason we carry them. Not really a supply house for batteries.

We also only recommend our batteries for back-up mostly and not really for Time 
of Use.  

Also, battery pack should be over-sized if they are going to use it for Time of 
Use.

Related question, Jeff... With the Sol-Ark, I an off-grid situation can you set 
it up to always use inveters to power loads. In other words, when the generator 
kicks in, only use the generator to charge batteries and do not bypass inveters 
to power loads directly from the generator. 

 

This is a request I get occasionally. People don't want to rely on the "dirty" 
generator power with sensitive electronics.

Hey all, I'm designing a microgrid sized off-grid system for somebody, and I'm 
just wondering if anyone knows of any issues with the following designs... 

 

The client says he needs 70 kW. His load data looks pretty solid, so I'm 
sticking to using that number as a minimum, at least during the initial 
proposal stage. I only know of two possible equipment options for this size 
range...

 
   
   - I think I can use up to 10 Outback Radians, for up to an 80 kW system. Are 
there any bugs or problems with using this many inverters on one hub? I know 
I've read about issues with selling to the grid, but that's not an issue, this 
is off-grid.
   - I know that the SMA cluster box with sunny islands can allow for up to a 
72 kW system. Do you know of any bugs or problems with this system?

 

 

Are there any other options that anyone would suggest? Schneider's website says 
they can only do up to 61 kW, and Victron can only do up to 60 kW.

 

 

I know that the Outback system would yield a 240/120 Split-Phase system and 
that the SMA would yield a 208/120 3Ø system, but this doesn't really matter 
either way for this job. 

 

Thanks so much,

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

[Dave Angelini Offgrid Solar]

I am confused by the 2 different Sol Ark systems. The large one looks
like it has a DC disco/breaker and a solar disco. 

The smaller solark
looks like it has a DC breaker only. Any guidance on what else is needed to
make these useable please?

I am glad to

AC bypass switching is a must for
SolArk. They need a PDP or some way to make this easier. The dual mppts are
perfect for virtual tracking. I begged for a dual mppt on the new Schneider

I wish them good luck and take back most of my

AC bypass switching is a must for SolArk. They need a PDP or some way

We've had great luck using the Tigo (and SMA) optimizers with SolArk to
conform to NEC2017 and CEC2018.

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

[Jason Szumlanski]

There is a huge distinction in a hybrid inverter that integrates MPPT
charge control. Eliminating all of the extraneous hardware and circuit
protection associated with charge controllers is very appealing. The 500V
input limit is also a game-changer in terms of wire size. I'm very
interested in this approach.

On the flip size, an AC Coupled approach is also appealing in a lot of
circumstances. Since Sol-Ark supports that, too, it's hard to find
downsides other than their infancy in the industry.

And for what it's worth, my experience with SMA tech support recently has
been abysmal. Long hold times and getting bounced around departments.

Hey Bill,
   They're still small enough that, at least so far, there is no hold music!
And we combine ac outputs with an "ac combiner panel" simply a single
phase or three phase panel, with each inverter feeding a breaker in that
panel and ensuring that we use either a main breaker that can be back fed
or a panel with feed through lugs. It is simple and safe and code
compliant.

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

[Mac Lewis]

The largest we've done is a 4 stack of 8k Radians and a 6 stack of Sunny
Islands with the Mutlicluster box.  They both have worked fine and there
are advantages to each approach.

An advantage to a multicluster approach is that you can have smaller and
segmented battery banks that don't require custom DC bussing.  Each cluster
master manages the battery bank.  The solar input can go straight into the
multicluster box since AC coupling works very well with SMA equipment.

Things get very busy with a Radian system quickly.  We had to use a custom
bussing system to combine the battery banks at around 1500A and miles of
4/0 cable to feed more bussing for the solar input and Radian connection.

Regarding getting the AC in and out of the Radian, we opted to use
dedicated panelboards for both the input and the output with double pole
60A breakers feeding in and out of each Radian.  It's also a good idea to
have a bypass switch upstream of the AC input panelboard that can bypass
the system if needed.

Both of these systems worked well but took a lot of planning for the
spatial layout and took a lot of wall space, much more than we initially
thought.

Good Luck and let us know which approach you take.

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

[frenergy]

OK, I'll bite.  I use SMA and Outback almost exclusively.  SMA for 
grid-tie so I can't vouch for SI for Off-grid and I don't seem to have 
the same wait problem with SMA, its usually 10-20 minutes.


            And Outback well they're not perfect but I've been 
using there stuff since day 1 (thanks Bob-O), still using FX3524 ser# 
0007 and been installing since they were Trace. Service?  well, let's 
just say it varies but I've been willing to put up with it.  The WORST 
part of of Outback service calls is the music they pipe in on 
'hold'...its enough to make you hang up.


            Sol-ark, the new kid on the block sounds slick and I'm 
genuinely tempted, specs look great..wonder what their 'hold' music is like?

Hey all, I'm designing a microgrid sized off-grid system for
somebody, and I'm just wondering if anyone knows of any issues
with the following designs...

The client says he needs 70 kW. His load data looks pretty
solid, so I'm sticking to using that number as a minimum, at
least during the initial proposal stage. I only know of two
possible equipment options for this size range...

 1. I think I can use up to 10 Outback Radians, for up to an
80 kW system. Are there any bugs or problems with using
this many inverters on one hub? I know I've read about
issues with selling to the grid, but that's not an issue,
this is off-grid.
 2. I know that the SMA cluster box with sunny islands can
allow for up to a 72 kW system. Do you know of any bugs or
problems with this system?

Are there any other options that anyone would suggest?
Schneider's website says they can only do up to 61 kW, and
Victron can only do up to 60 kW.

I know that the Outback system would yield a 240/120
Split-Phase system and that the SMA would yield a 208/120 3Ø
system, but this doesn't really matter either way for this job.

Thanks so much,

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

[penobscotsolar]

What do you see, Dave? We have 6 12 kW and two 8 kW installed so far in
the Bahamas and two here in Maine, all with Fortress batteries, and I
cannot be more pleased. I do wish they had a remote monitor panel for
easier at home monitoring and I guess I would rather they had their own
monitoring system instead of Powerview, but compared to others I am
thrilled at the ease of installation and programming, zero service calls
and wireless connectivity for monitoring over the internet.

Thanks,
Daryl

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

[Kienan Maxfield]

Thank you all so much for the suggestions!! I hadn't thought of SolArk, but 
I'll have to include that in my proposals. It sounds like they've really 
gathered quite a following.

Thanks,
Kienan

Hi Joe

A correction

Both the 8 and 12kw are 9 kw inverters
In off grid mode according to the specs.

For grid selling the 12kw is 12 kw.

I also suggest the Sol-Ark 12’s. Extremely efficient, simple to program, does a 
wonderful job in either ac coupling, stand alone or pure off grid and terrific 
customer support.

Sol-Arks would be possible, you can link 8 inverters.

I'd suggest giving the crew at Sol-Ark a quick call @ 972-575-8875 with their 
12kw unit. Not sure what their max number of inverters are.

Hey all, I'm designing a microgrid sized off-grid system for somebody, and I'm 
just wondering if anyone knows of any issues with the following designs...



The client says he needs 70 kW. His load data looks pretty solid, so I'm 
sticking to using that number as a minimum, at least during the initial 
proposal stage. I only know of two possible equipment options for this size 
range...



  1.  I think I can use up to 10 Outback Radians, for up to an 80 kW system. 
Are there any bugs or problems with using this many inverters on one hub? I 
know I've read about issues with selling to the grid, but that's not an issue, 
this is off-grid.
  2.  I know that the SMA cluster box with sunny islands can allow for up to a 
72 kW system. Do you know of any bugs or problems with this system?





Are there any other options that anyone would suggest? Schneider's website says 
they can only do up to 61 kW, and Victron can only do up to 60 kW.





I know that the Outback system would yield a 240/120 Split-Phase system and 
that the SMA would yield a 208/120 3Ø system, but this doesn't really matter 
either way for this job.



Thanks so much,

[RE-wrenches] Microgrid... Outback or SMA or other?

[Kienan Maxfield]

Hey all, I'm designing a microgrid sized off-grid system for somebody, and I'm 
just wondering if anyone knows of any issues with the following designs...

The client says he needs 70 kW. His load data looks pretty solid, so I'm 
sticking to using that number as a minimum, at least during the initial 
proposal stage. I only know of two possible equipment options for this size 
range...


  1.  I think I can use up to 10 Outback Radians, for up to an 80 kW system. 
Are there any bugs or problems with using this many inverters on one hub? I 
know I've read about issues with selling to the grid, but that's not an issue, 
this is off-grid.

  2.  I know that the SMA cluster box with sunny islands can allow for up to a 
72 kW system. Do you know of any bugs or problems with this system?


Are there any other options that anyone would suggest? Schneider's website says 
they can only do up to 61 kW, and Victron can only do up to 60 kW.


I know that the Outback system would yield a 240/120 Split-Phase system and 
that the SMA would yield a 208/120 3Ø system, but this doesn't really matter 
either way for this job.

Thanks so much,
Kienan
