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?

Only a complete spare will save the day, or night...Also wonder about real world surge capacity on 1 hp pumps and big air compressors. I am glad to hear that they will be making this in Texas, rather than currently only in China. Anyone have more on this please? 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 high voltage 100a mppt :( I wish them good luck and take back most of my concerns. Hope they can make it!

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.

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.
