I have two HPWC chargers in two houses. Both work fine at 72 amps.

One has the dripping green lights when charging, the other just a constant green.

Anybody know why?

I've ordered one, hoping to have it installed with 60 Amp service in the next couple weeks. I'm happy to hear people are running higher than 30 Amp service on them with no issues.

Is one charger older than the other? Could it be the way the switches are configured inside the box?

I have two of the newer models and they both work fine at 80 amps (I have an older S with dual 40 amp chargers that charges at 80 amps) and both show the dripping green lights when charging.

Is it properly charging? IF so, then maybe an incorrect wire connection internally to signify charging. I'd say if it charges properly, then ignore that it isn't dripping.

An HPC should “drip” when charging and go solid when finished with the cable still connected.

If they both work properly to charge your cars it doesn’t seem worth the effort to complain to Tesla and get one replaced, in my opinion (I am not implying that is your plan).

That little ribbon cable that connects those LED lights is pretty fragile and may not be fully seated in the connection. I’ve noticed a few times when I hang up my cable into the side of the charger my green light went out completely. Only to get home and it’s back on. Haven’t taken the time yet to remove the cover and check that little plug.
