Sigenergy (PointGuard) Home system with generator input (Pro Power Onboard).

Does it stand between the main panel and a subpanel? I assume there is something standing between your gear and the home's main power feed that allows it to operate disconnected from the grid? Are the inverters handling that themselves?

The white box on the wall is their load hub which is their 200A automatic transfer switch. The inverters can work on-grid only without it, but the load hub is required for off grid operation.

It is service entrance rated, so it can go between your meter and main panel for whole home backup, but in my setup I have it between my main panel and a sub panel. Honestly my sub panel is almost all the home loads except the dryer, oven, and Ford charge station.

I have it hooked up at 150A for the line side, and the full 200A for load. It also has 8 additional smart breakers (think SPAN panel). 2 are dedicated for inverters, 1 is a dedicated generator input that only can turn on off-grid, and the other 5 can be used for smart loads or other inverters (like my old SolarEdge solar inverter).

The Sigenergy acts as a UPS. You honestly would never know if you lost power and go off-grid unless the app tells you about it. I basically run my house like its off grid all day anyway where I run 100% off battery and my small solar system (and now the Lightning too).

Today I tested charging the lightning only off of excess solar and once the home batteries were full, which worked perfectly. Tomorrow I am going to turn on the full bi-directional charging and try running the house off the truck. Again the nice thing is I can play around and test this, and the rest of the family doesn't even know because it works so well.

Now having the V2X module, I can finally connect the ground pin in the generator inlet box. IYKYK.

I am going to write up a completely new thread with all the info included here and a lot more on the V2X. Some of the write up and comments are now outdated in this one.
