Old computer geeks of the world unite! 😀. Double MCSE/NCE here also! Before that....Unix on the IBMs with reel-to-reel for data...TRS80...

How about my NCE… netware 3 certified baby!

Oops - corrected. I don't have BMS that I can connect to with Bluetooth to see what it reports. That's what I meant. Thanks. MCSE...

We are South of Cleveland, out in the country...dead nuts in the totality and it was awesome from the back yard! We had some very high...

I too have installed pairs of interlocked breakers to allow the panels to be fed from either the utility or inverter, I just didn’t...

Can you post a screenshot instead of a pdf link? Links limit what people can see, and make it more time consuming plus they load up...

Yes, double conversion (ac->dc->ac via CV) is allowed by basically all POCO but note you will be limited to SolArk's output power...

I think spurious feedback is fine (as far as 120% rule, shouldn't need to derate anything in this case.) Maybe utility will complain...

I installed my main panel upside down. The only stipulation I could find was that Off can't be up. So a sideways breaker satisfies that...

We have 16.7 kW of bifacials, the SA15k, 25 kWh of SOKs in hand and Kyle Sinclair's season-adjustable ground racking for the panels...

We are kindred spirits. The install thought process started as a SA 12k, and 12kW of panels. 😀 ......and with a new HP water heater...

The POCO (a 'cooperative', but they're not) pretty much laughed in my face when I told them I wanted to put up 16kW of panels and...

Sweet...there's a 200 amp in the old panel currently! SA will be configured for no feedback, but consensus seems to be that AIOs aren't...

Glad to...stand by!

This post has a link to interlock for one model Square-D 150A ... 225A panel. Be sure to get one that matches your panel...

What are your thoughts on this option? Thanks! Jim

Please sketch a schematic. I'm not clear if you are letting current from main disconnect plus current backfed from SolArk add together...

Admittedly, it's early, but this is going over my head. Diagrams/pix/links of the interlocked breakers (is this inside a single MEP...

I believe the SA should only energize AC in if it sees grid. (Under my default assumption that a hybrid or grid tie inverter always...

Thanks for the great feedback, guys...you are an amazing source of info!
