With thanks to Will Prowse for creating this forum, I would sure appreciate any help here proofing my "wiring" scheme....
This is an upgrade from an EG4 6500 split phase system that has been running fine for over a year, but for longevity reasons I'm going with the 6000XPs. My son and I will be switching out the inverters in a few days so I've put together a DIY friendly diagram for those of us that have more challenges with traditional schematics. (FYI- The inverter connections are straight forward in countless videos which is why I have not pictured them. The symbolic conduit depictions vary in color for readability and in width to accommodate showing the 4 colored THHN stranded wires and also their relative widths as they enter the inverters.)
This is an off-grid split phase system using the utility as a backup when short on sunshine and battery storage. It is powered by 21 roof-mounted Solarever panels 440w each. I prefer adding a whole house xfer switch to be back on the grid while addressing any problems with the solar system, but my budget is limited for now. I had already migrated all the 120v circuits to the sub-panel for the previous setup. The main panel has four 240v circuits, two of which I will move now to the sub-panel. Before proceeding we need to know:
(1) Are there any glaring and embarrassing errors right off??
(2) Is the neutral/ground bond format correct?
(3) Does the AC in and out (Black L1, Red L2) have breakers and wire gauges sized adequately and are their respective neutrals/white and grounds/green landed in the right places in the Main and Sub-Panel?
(4) Given the serial strings we have, are we still within the 480v limit of the 6000XPs in our eastern TN climate? (We were within the 500v limit of the 6500EXs.)
