I have one Powerwall 2 + Gateway 2 installed by LA Solar. They told me that this system would back up ALL my 30-amp and lower circuits (about 100 amps from a load calculation), transferring them to the subservice panel. But at the install, I was told I would have to choose critical circuits for backup, which I did. After several months of discussions with LA Solar, they told me they could transfer all my 30-amp and under circuits to the subservice panel, but that my battery would run down faster. When I asked if a high load would trip the battery circuit breaker, they told me no. Now they are telling me that the Gateway 2 is a smart switch and can shut off loads that are too high for it to handle during a power outage, and won't shut off. At this point, I have no confidence in what they are telling me. I can't find anything on the internet on how the Gateway actually works. Does anyone here know, or know where I can find this information? Thanks for any help you can give me with this.
