From my memory of the presentation yesterday: - 200A grid pass-through with ATS (this really is a nice feature for grid-connect, no need for an outboard ATS) - 15kw continuous inverter capability from DC connected solar - 12kw continuous inverter capability from DC connected battery. The...

It does output 15kw from dc connected panels; the 12kw limit is just from battery… and for what its worth, even that limit seems just to be a software limit since the battery connection is a pair of 200A breakers capable of 20kw…. So I would not be surprised to see down the road if this 12kw...

With two 15Ks... and therefore 6 MPPTs, how are you planning to divvy up your solar? 4 strings of 8, two on each 15K - leaving one MPPT on each unit unused? I'm curious of whay you chose (and more importantly WHY). Being efficient is exactly why we are planning to build to Passive House...

In doing some reading online, a few thoughts: It seems Sol-Ark is going to rebrand with an upgrade to "Limitless 9K" and "Limitless 15K", reflecting the inverter limit and not the solar limit. If the limited data out there is correct, the 15k unit will: Be able to handle 18kw solar Have a 15kw...

LOL - yeah, let's call it the Sol-Ark 12/15/17/20kw so we can cover battery and solar inverter limits, total dc panel limit and peaking capability. That wouldn't confuse anyone. :). Oh wait, wouldn't we need to add 24kw in there to show the max amount of AC coupled capacity allowed on the Gen...

Another option is to AC-Couple those west-facing panels on your generator input, assuming you aren't using the gen input already...

24 x 5kw batts? Wow! How long will this last you and how much solar you putting up?

I was glad I asked about the battery limitation, too. Always good to understand the design constraints. Makes me wonder if 48v batt days are limited. Triple the voltage to 144v, 15kw from batts is only 104 amps… and one of the two 200a battery breakers could be removed. But to your 4/0...

Curious about voltage drop due to cabling… if you are factoring in 2% voltage drop when under load, should that be factored into these numbers? Or is that irrelevant, since that drop is calculated for high current load only?

I definitely am aware that the ASHP based water heaters are the efficient/electrical choice... BUT... I'm honestly concerned about the long recovery times of that solution - hence the on-demand/propane system. Add to that, Oregon's climate is dealing primarily with heating, less so with...

200A pass through is definitely really nice for grid-tie. I see a pair of these in my future. For what it's worth, this will be running both our house + a 1200-ish sq ft woodshop, both built to Passive House standards, so I think even with both buildings on this - even if there were a power...

I've been a network engineer for 25-ish years at this point. While the money is amazing... my passion for it is gone. We've saved enough that I could stop working completely, but I'm planning to make a transition into the green building industry in ~ 2 years (I have a few projects, and a LOT...

Question about how quickly manual transfer switches operate with regard to bypassing an inverter. If, under a normal grid-tie scenario, we have the inverters feeding the main breaker panel... and we have a MTS wired as a bypass so we can go direct-to-grid and bypass the inverters (e.g. if doing...

Two of these 15k units in parallel and no need for a critical load panel, either. Looking forward to their announcement in the coming month(s). Unfortunately, I’m a minimum of 3.5 years from being where we can go solar... on the bright side, this new product will be out and have several...

What type of batteries you thinking? Been reading some stuff on these: https://www.signaturesolar.com/products/48v-100ah-lifepower4-battery-by-eg4 Seems that two 6-slot racks, using the busbars built into the racks for each group of 6, then connecting that back to the Blue Sea busbars to...

For giggles, Googled "Sol-Ark 15K" this morning and got this link: https://kinectsolar.com/product/sol-ark-15k-p-15kw-hybrid-inverter-120-240-208v-10-yr-warranty/ No pricing, nor any specs. But makes me think an announcement is coming soon. :)
