I've done quite a bit of research on this, but I've had a hard time finding reliable information. My wife and I are interested in adding solar to our home, but she is (understandably) concerned about the number of boxes that will be on our walls. I see that the Powerwall 2 comes in a model that has an inverter built in, yet all of the videos of setups I've seen online involve a separate, external inverter. Is there an advantage to having an external inverter? We're really just looking for our solar setup to do the usual things: Have the solar power the house and charge the Powerwall 2 (when it can) Run the house off of the Powerwall 2 when the solar drops out Use utility power as little as possible From my understanding, if we eliminate the external inverter, we'd just four boxes: The breaker box (which we already have) Utility box (which we already have) The Powerwall 2 Tesla Gateway Any insight would be appreciated! Thanks!
