No, the Gen1 and Gen2 were big beefy ones that could always be used on up to a 100A circuit and provide 80A continuous. There were awesome, bulletproof products. The Gen2 introduced the circuit sharing ability, but they could always be used for 80A by themselves anyway. The Gen3 was a really annoying step down: less reliable and only 48A maximum supply. That was frustrating some people who still had or were buying used Teslas that still should have been able to use 72A or 80A.
