    It looks like you would wire the system this way (is this a Tesla PowerWall system?):

    Four Steps to Long-Term Backup Power

    Here’s how Tesla Powerwall will work with your generator:

    1. During a grid outage, your Tesla Powerwall will automatically turn on before your generator.
    2. If your Tesla Powerwall depletes to its minimum setting, your generator will automatically turn on.

    During a long-term grid outage, once your Tesla Powerwall is out of energy, you will flip the Manual Transfer Switch to have your solar charge up your Tesla Powerwall.

    1. Your solar system and your Tesla Powerwall will not power your home while your generator is running. Instead, if the sun is up, your solar will charge your Tesla Powerwall while your generator powers your home.
    2. Once your Tesla Powerwall is fully charged, you will need to manually switch your home from your generator back to your Tesla Powerwall. It’s as simple as restarting your Tesla Powerwall.

    Depending on how long the grid out, you may have to repeat this cycle. While almost everything happens automatically, the key point to remember is that every time your Tesla Powerwall is depleted, you will have to restart your Tesla Powerwall once it’s charged, that’s it!

    During an extended grid outage, the more conservative you are with your energy use, the less you will have to use your generator and potentially costly fuel.

    If your system is a Tesla Powerwall, you will probably have to work with your Tesla dealer/installer to integrate with a genset....
