I was hoping to fine tune things so that if I have a power outage during the day, the Sunny Boys would provide most of the power and the generator would have a very small load on it. But that might be too fine a balancing act to try to pull off for what it probably not a huge amount of fuel...

Great suggestion about just getting a switch capable of being powered by DC directly! So I'm a bit of a UniFi fanboy already, lol: So I plan to stick with equipment from them. Long term, I plan to build a small cabin down in the field near the river. So with that in mind, I might just get...

I don't see why HA would not be able to change inverter modes, but I'm not aware of any of the inverter integrations supporting that at this time. I primarily use HA to just monitor what's going on. My inverters are grid tied and after the initial configuration, I have not had a need to go...

Lol, tell me about it. I seem to perpetually be on their notify list for when they get stuff in stock. Been on the waiting list for their Camera AI360 and Bullet for what seems like an eternity already.

That all makes sense. So it looks like the multifunction relay can be used to turn the load on and off as follows: So I should be able to wire terminals 1 and 2 in parallel for all 8 inverters, and connect to the NO contacts of the transfer switch. Right?

Good idea about landing the SBs on the grid side of the ATS. For me that will be easy and only involving extending a couple of 300 MCM cables about 4' as shown below: I already have dual lugs in the disconnect switch, so wiring up the SBs would be natural. I can't wire them directly to the...

A guy on marketplace has 4 of the 6048US brand new sealed on a pallet for $2,900 each. But looking at the shipping label, it looks like they are NOS as it shows 2017. Perhaps not a big deal as they do have a 10 year warranty. The Power Store, where I got my SBs from, has them for $3,466...

I recently decommissioned several large arrays that were running the Ubiquiti 250W Micro Inverters. I'm the original owner and purchased them all in October 2016. They have a 10 year warranty and I'll include a copy of the original invoice for warranty purposes. About 15 are brand new RMA...

So it seems that the SI8.0 is being sold state side now at a very good price: I haven't purchased from ecrunch.com but they seem legit...

I find that very surprising. I can see how North facing panels do ok in the summer months, but would be terrible in the winter month where they may not even get any direct sunlight, depending on the pitch of the roof they are on. But I would have thought East and West panels would produce way...

Thanks, so I guess more specifically one or more of the REC-BMS Q-BMS 16S, depending on how large a battery bank I want to build? Man, this sure is starting to add up...

I wish I had 3 phase power on my street, but my little side road is just 14.4K single phase on the pole. I would have loved to have been able to just buy a single honking 60 kW inverter! I did not know that DC had a greater loss over distance than AC, for a given gauge wire. The only reason...

I just realized the 56A relay limitation in the SI is @ 120V per your comment above. So that means I would need 8 SIs to be able to backfeed 50kW plus back into the grid. And that's definitely more than I want to spend. So yeah, let me think about how to redo the diagram to only have some...

Got the SBs extended to land on the grid side of the ATS. Its the 2 wires you see running along the bottom of my "junction box" via the 2 large straight through Polaris connectors. I got quite a collection of those now. And here they come up into the 400A disconnect: (the right Blue/Red...

I always wondered if the poco ever "catch" folks with more solar than they are supposed to have. I know in VA where I live, residential systems supposedly max out of 20kW. I started out with 20kW and was inspected for 20kW when my net metering agreement was established back in 2016. I have...

The panel frames are making direct contact with the superstruts. But yeah, the NEC would probably not consider that enough. All the panels have pre-drilled holes in the frame that I could use to ground them all, but with 60 panels, that would be a huge pain. I used 1/4" stainless steel EPDM...

Any word on when then SI 8.0H will be stateside? It looks very nice. https://files.sma.de/downloads/SI44M-80H-13-BE-en-14.pdf

That sounds like quite the project! So in trying to size what I would need, I took a look at how much I consume and what my peak loads are. Here's what the 22nd looked like: It wasn't that crazy cold on the 22nd, but this morning is very cold (4F), and as a result, my heat pumps are working...
