Amphenol connectors and SolarEdge optimizers were "quarantined" as part of Project Titan and were either reworked and put back on roofs or scrapped, a former Tesla employee, who asked to remain anonymous, said.
To execute Project Titan, Tesla ordered supplies including ladders and tool belts and sent crews out around the United States, according to the former employee. The replacement parts had to be ordered as well, as all of the Amphenol H4 connectors were to be replaced with MC4 connectors.
This didn't happen all at once. Standard operating procedures had to be set, crews had to be put together, according to the source. In December, 188 Tesla trucks were sent out to almost 50 US cities to change out faulty connectors and optimizers in support of Project Titan, according to Tesla documents viewed by Business Insider. Tesla declined to comment on this.
