Gen 3 HPWC 48amps

[Petrlol]

I've been contemplating getting a HPWC for 2 years now, and frankly the posts here an on Reddit are terrible for the 3rd gen.

All I see is overheating, reduced charge rate, flashing red lights, Wi-Fi provisioning issues, bad batch that needs replaced, caused by firmware, etc...

How many people here use the gen 3 HPWC daily at 48 amps and have 0 issues?

We had one installed, on a line directly off our main fuse box/6ft of conduit/through a brick wall, into our non-HVAC garage that regularly sees temps over 90 degrees through the TX summer/provisioned it onto wifi same day...

ZERO ISSUES. EVER.

I had one installed and had early issues. But it turned out that I had not followed the installation procedures. I failed to notice that I had to "Commission" the wall connector. After I scheduled a mobile service. They called a day after I made the appointment and told me to connect my wall connector to wifi so it could be checked and updated. That night it charged all night at 48 amps and has continued to do so for the past month or so.

I haven't had any real issues other than that the charging cord gets pretty hot, even more so with direct sunlight on it.

The amperage always stayed at 48 A though, regardless of the firmware version.

I'm a happy gen 2 HPWC user now.

I saw all the issues so I found a new Gen 2 on eBay. $30 over list. I lucked out because many sell for $700 to $900. I also wanted the 24 ft cord.

Still waiting patiently for a long-term fix since June 30...

I have one on a 50A circuit, so it's running at 40A, but it has been flawless since day one. Not a single error. I seem to be in the minority though, my buddy got his MY a few weeks before me and his charger is giving him the three blinking red lights a lot.

I replaced a 5 yr old gen 1 having connector issues with a gen 3. No issues at all with a 50A circuit charging at 40A. This is in an extremely hot garage (often 105F) in Phoenix in summer. The cord is marginally warm, not hot. Though I did have the garage open one time and the sun was shining on the cord making is really hot. But still no problems charging. Had FW .58 from the factory. I believe it has upgraded since then, but I can't see as the upgrade broke the charger web page (see other thread on this).

So not as many responses as I'd hoped for but 12/16 no issues and 4/16 some or constant issues.

25% issue rate isn't exactly great...

Thanks for those who provided feedback!

I have 2 with no issues.

There are other manufacturers that charge at 48A if you’re not thrilled with Tesla as a choice. ChargePoint Home Flex is an option

Thanks,

I'm just going to chill with the mobile connector for now I suppose, maybe wait it out to see if it gets better, or get a gen 2 on ebay if not. Don't really want to go 3rd party charger.

Had overheating issues, Tesla sent me a new charger, no issues.

I have the Gen 3 HPWC, on a 60 amp circuit and have no issues, although I usually dial the charging speed down to far less than 48A because I rarely need to charge that fast. The only time I’ve charged at 48A was when I was driving around town a lot right before a long trip, but worked fine charging at 48A for well over an hour. Otherwise dial it down as to not stress the wiring unnecessarily. If charging at night 48A is kinda overkill.

 

[mcorf]

I have two of them and run them at 48A all the time. I have never had any problems since they were installed this summer.

 

[FredMertz]

Is there a longevity or operating benefit to going lower than 48? I never let the car get much below 70%, so charging speed is never really an issue, so I'd see no harm lowering the rate if it will help in some way.

 

[mcorf]

If you want to run at a lower speed then save your money and get a NEMA 14-50. I had one for 6 months and it charged perfectly at 29 mi/hr.

I have two Gen 3’s. Each hooked up to a 50 amp breaker however if both were going at 40 amps it would be too much for my sub panel. So even though I currently have one Tesla out of an over abundance of caution I have one set to 24 amps and the other set to 16 amps.

Once WiFi balancing is enabled I’ll put both on 40 amps.

No issues.
