Generators of old were very loud. Even so, after a particularly nasty storm, the sound of chainsaws is like a sweet symphony.
This was a Generac. It was like being on a cruise ship - you ALWAYS heard it. Bugged the pah-tootey out of my wife.
Sadly the $$$ generator was paid for, so we kept it. The solar controller is made by Enphase, and Enphase will be releasing the module that integrates the generator into the solar system. The wall-mount controller has an open slot for this gizmo, but the one we need is slated for early 2023.
Adding that would give us solar+ solar battery + fossil-fuel generation capacities. All local, and capable of running automatically in a grid-down situation.
Right now *IF* the grid was down *AND* the solar system failed, I can manually switch in/isolate the existing generator by doing some work in the main panel; take me about 20 minutes. I like redundancy.
