Basically made a really sturdy pergola and then mounted solar panels to it. Ran that wiring to the MPPT, batteries and inverter in the garage. Put in a new small breaker box right next to the existing one, which made it real easy to just grab the wires for the critical loads and run them over to the new panel.
No need to worry about backfeeding, as I said they’re parallel electrical systems, so it’s not possible.
I don’t understand the parallel part. Do you mean independent, so the critical stuff can only get power from the solar circuit? Since it’s critical stuff, do you have a fallback if solar production is low? Is your battery 24 or 48v?

I mean the 2 systems are not connected in any way. They’re completely independent.
If it stays cloudy for a few days, or I am anticipating a potential outage, I can plug in a battery charger to the grid.
My batts are 48V EG4 units. But I would go the “DIY” route if I were to do it again, they are considerably less expensive.
