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 Maxfield Solar [email protected]<mailto:[email protected]> (801) 631-5584 (Cell)
