I currently have a 24' Gen 2 HPWC installed on a 60 amp breaker to charge my Model 3 at 48 amps. Starting to plan to get my wife a Model Y. I don't have capacity in my panel to run a second HPWC at full rate, so needing to do a load sharing setup. I'm going to end up having to make a choice between trying to find a second Gen 2 on the resale market (hopefully without getting gouged on price), or selling my Gen 2 and buying two Gen 3s.
I understand the "how" of load sharing between Gen 2 and 3, wired vs wireless, and that Gen 3 load sharing hasn't actually been released yet.
My question is regarding wiring. I see that each Gen 3 requires it's own branch circuit and a dedicated breaker. So in my case, even though I plan to share 48 amps total, each unit would be on it's own dedicated 60 amp breaker. Unless I'm misunderstanding, that's pretty straightforward.
Can I run two Gen 2s in the same configuration? The manual shows one branch circuit with a single breaker (60 amp in my case) running to a junction box, then each HPWC wired into the junction box. Because of the proximity to my main panel, I'd prefer to have two separate branch circuits rather than having to install a junction box. I guess I'm just not understanding why Gen 2 would require a single breaker/circuit with junction box where Gen 3 requires separate breakers/circuits. Both setups are load sharing, it's just the communication method between them that's different. Am I missing something here?
