I have this pretty much and generating way too much power for our needs which is great. And that includes car charging for light but significant use. I export a lot during peak hours from the battery as there is a lot of surplus.

But I was snarking on "provider". There are 100s of providers where I live but one grid and you can't use two concurrently.

My backup in the past has been a local library for internet and laptop power and everything else can wait.
