  • Offgride: Grounding is making my head spin. Basic setup

    I’ve got a pretty basic off grid solar system. Perhaps someone can help guide me here. I just need to know how to ground the system correctly. I don’t want to create a ground loop or ground something that doesn’t need to be grounded.


    My system is as such:
    Roof of aluminum sunroom> 2x 330w 37.8v solar panels in series > inside the sun room > charge controller > 100 ah 24v batteries on BMS > Busbars > 24v 2000w ac inverter.

    Nothing is currently grounded. Even the solar panels are isolated with VHB tape. The charge controller, inverter battery and busbars are in a wood box.

    For code reasons, I am in Tampa Florida.

    There is a 1p breaker on each component

    Equipment:

    Panels
    Inverter
    Charge controller
    Battery
