    Off-grid inverters bypass a LOT of that. And i should have been more clear on no backfeed. I would never recommend backfeed tbh. It comes with insane amounts of red tape, as you’ve noted, the equipment is also much more expensive for grid tie.

    Off-grid inverters are basically a backup UPS on steroids. They accept grid as an input but don’t feed back to it. They have far less regulation on their installations. Some places indeed you will still have some but usually you can get away with just having the final install inspected by a master electrician.

      That’s fair. For me, I don’t have enough roof space or space for battery to do a fully off-grid system. I would have liked to, but I’ve got mountains to the west and I only get good sun on the southeast facing side of the house, so unless I do a porch expansion and battery capacity to size ratio improves, grid-tied was my best option.

      My power company is a not-for-profit co-op and offers 1:1 net-metering, as well as reduced costs for off-peak hours for solar and heat pump users. I’ve managed my energy use to the point I’m at net-zero usage (101.5% production to my usage), but there are low production days where I have to tap the grid and high production days where I produce way more than I draw.


      Edit - other considerations as well, e.g. - solar installer guarantees the work for 15 years (panels) and 10 years (battery) and will fix any issues free (if they’re still in business, if not it’s guaranteed by Solaredge given professional installation). And Solaredge tends to not work with individuals. Honestly, I did look into self-installing and IIRC I would have saved maybe $9k or $10k doing a DIY install, but given the tools I would need, knowledge and resources to do it right, time required to do it alone, and the lack of grid access/backfeed… it was very much worth the extra cost to me. And that additional cost was technically refunded to me when I filed taxes.
