    Need some guidance before I pull the trigger

    Thanks everyone, I'm learning a ton here. @Hedges - Can your system automatically shed loads based on SOC? If so, what type of equipment supports that? A smart panel type thing? @zanydroid - But if I had a 125A main breaker, I'd need a 125A transfer switch right? I can't find any 125A transfer...

    Awesome, thanks for confirming my thinking! Can you explain this one a bit more? Not sure I follow. This is probably ignorance on my part but I’ve attempted to add up a realistic (but unlikely) max load that I could pull from the panel at any given time and it’s just barely over the 12kw / 50a...

    Ah I see, thanks for looking that up! I had the utility spot my meter upgrade and they approved a max panel rating of 125A (up from my current 100a panel), based on the feeder conductors. Sadly, I’m underground fed so upgrading beyond 125 will be extremely expensive. This also means I can’t...

    Amazing, I like that configuration. Circling back to the 100A main breaker and a single 100A breaker that is tapped to feed both inverter and panel… you said this: Is there a name for this rule? And does that mean the 120% rule is not absolute… it’s just one of a few rules that must be...

    Oh! I see - I dig your idea to keep the 100A main breaker and then have only a single 100A breaker on that panel and tap it downstream to both the panel and the inverter. I think that's the best of both worlds! It would allow me to keep my 100A grid connection while also allowing my inverter to...

    @Hedges - what if I swapped out my main breaker from 100A to 70A? 😬 Is that a terrible idea? haha.That would allow me to make the inverter breaker on my MSP 50A (see diagram below). I understand that this would limit my grid draw down from 100A to 70A. However, in my head I think that could be...

    Ok, I think that is all making sense. Thanks for breaking that down for me. Sounds like I’ll need to upgrade my service and panel. Bummer, this is turning into a bigger undertaking.

    Oh - hmm. I guess the inverter is itself a load even if there are no downstream loads from the inverter (e.g. it can still charge batteries)... is that right? I think maybe that's what you were saying. I think I am understanding now. So is this where the 70A breaker comes from: (1.2 x 225A bus...

    Thanks @Hedges! Still trying to understand this though... In my head, replacing all loads on my existing panel with a 100A breaker feeding a sub panel (with all the same loads in it) is identical to what I have now, right? This shouldn't be breaking the 120% rule... if I am understanding things...

    Thanks for the replies, all super helpful! @Hedges - great idea to configure the inverter to only export a certain amount in order to remain in NEM 1.0. I'll look into that. @JBertok - I love this idea about the critical loads panel but with all of my loads. Makes perfect sense. And it makes...

    Hi all! First post and I must start out by expressing my gratitude for this community. I’ve learned a ton in the past several weeks. Thanks! I would love some help in designing a system for my situation. Any and all advice or comments are much appreciated! Here’s my situation and what I’m...
