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

Wed Sep 9 11:32:51 EDT 2020

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.

we've found SolArk to be SOLID!! .. And yes 8 inv yield about 96kW, with a TON of surge capabilities..

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,

Kienan
