Solar and battery backup is extremely reliable but there are occasional instances where qualified service is needed.
This Powerwall 2 installation was part of a proactive warranty upgrade program by Tesla.
The batteries and transfer switch were provided to upgrade to Tesla Powerwall3 and Gateway3.
During the upgrade the customer took the opportunity to replace the bankrupt Sunpower PVS6 monitor with Enphase to preserve the warranty of the inverters and upgrade the total amps from the batteries from the limited total of 48a for Powerwall 2 to 96amps with Powerwall 3.
This is more than enough power to run his HVAC and other household appliances comfortably during an outage.
What makes this customer unique is that during outages he helps his other neighbors by letting them store critical medications š in his garage fridge because he has free fuel from his solar panels to keep his lights on, food cold, and house comfortable.
