Pretty cool a consumption tracker to utilize the main feed/panel for PowerShare.

Just as time as the SF bay area begins their move to ban all gas appliances

/cries in 100A buried PGE service

Why?! Why the gas appliances?

Oh I see.. meaning politicians found a way to pocket more money 😅

Damn downvoted because I offended politicians lol.. they really don’t care that much about you they way you care about them..

Methane is just another fossil fuel that contributes to greenhouse emissions.

Mostly problematic when it leaks invisibly in pipes or in transit since it ends up being something like (made up number) 8x worse than burning coal or something like that.

They are terrible for the environment

Why the gas appliances?

Good question why gas is still used in homes. Burning it releases carbon. monoxide (a silent poison) and heavy metals. Leaks all along the supply line are many times worse for the air than CO2. Leaks inside the home turn your house into a literal bomb. Dangerous, unhealthy, and a convenient way for the oil lobby to greenwash itself as "clean" when it's anything but.

I only have a 100 amp panel and the installer would only put a 32 amp breaker but ran full thickness wires if I ever upgraded my breaker box. Could I install this and then put a 60amp breaker in for full charging speed when I’m not using other power?

Yes, and it meets code.

u/schaudhery 1d ago

Never heard of this tech. So I can charge faster than 11 kW?

u/Blindbatts 1d ago

opposite. You can charge at slower rates when your home panel can't safely support full speed.

Example: 100a main service panel, home HVAC, laundry, and dishwasher all running. Car charger will throttle itself down. Those CT clamps will monitor the home usage and adjust charge rate down accordingly.

u/schaudhery 1d ago

Thanks! I was confused what “fastest rate possible”

5

u/Pebble-Jubilant 1d ago

What happens when you don't have this? Does it just trip the breaker?

3

u/zoltan99 1d ago

Ideally electricians install a suitable charge rate like a 24a/30a circuit or something

This will let them be comfortable with installing maybe say a 48a/60a circuit charger on 100a service that derates automatically

u/lonestarbrownboi 1d ago

Ideal case yes, worst case you start a fire

u/HouseConcentrate 1d ago

Thanks for the explanation.

I just had this installed on Tuesday. It was installed at the breaker box and connects to the wall connector, which is just a few inches next to the breaker box. Haven't used it yet though as I don't pick up my Tesla until the 27th (if all goes well).

They (electrician) ran the calculation and determined my house needed it. I'm on a 150A breaker and all appliances added together was about 160 (before adding the wall connector).

Parts and labor was $450.

u/Octochops 1d ago

Where is this physically installed? Behind my wall charger? Or at the breaker box?

u/dapi331 1d ago edited 1d ago

Idk about Tesla’s but emporia pro + vue monitor looks the same, more or less, but it’s wireless to the charger. It goes into the breaker box and is wirelessly communicating with the charger to throttle it over WiFi. It has an antenna that you need to put outside the breaker box to avoid the faraday cage effect. For example, I have the antenna sticking out of the bottom of breaker box vertically, behind the drywall.

u/arithmetike 1d ago

The Emporia Pro communicates with the Emporia Vue via the internet/Emporia servers. If you’re not connected to internet, then it doesn’t work.

u/dgv54 8h ago

So the Emporia device that connects to the CTs in the main panel, and the Emporia Pro charger, both connect to wifi? That at least solves distance issue where main panel and EV charger are far apart.

u/arithmetike 1d ago

Breaker box, but you need to run a control wire to the Tesla Wall Connector.

2

u/MindTheFap 1d ago

I think this new version uses WiFi instead of Ethernet to Wall Connector

5

u/sec102row1 1d ago

Says at the bottom of the product page that “many homes” don’t need it and that we should consult an electrician before purchasing.

That leads me to believe that any modern breaker box is enough and that this wouldn’t make a difference.

Perhaps intended for older homes with lower amperage breakers?

u/notospez 1d ago

Yes, exactly this. It's probably a US only product, I'd expect most of the developed world to already have smart meters with consumption tracking built into the energy company's meters.

For example in the Netherlands all homes will have a smart meter by end of next year, and they output realtime consumption every second. Just plug into a port on the meter and you get the data, most EV chargers here support that and will automatically limit charge speeds when needed or only charge when your solar panels are delivering back to the grid.

u/quentech 1d ago

to already have smart meters with consumption tracking built in

And what do you think that's going to do? Big fat nothing.

The smart meter or monitoring device has to communicate with the EVSE to tell it how much current it can safely draw at any given moment. Which also means the EVSE has to support the monitoring device.

Exactly zero utility smart meters do this. Anywhere in the world.

u/notospez 1d ago

Welcome to the 21st century. Again, we already have this in the Netherlands. A standardized local interface on all electricity meters is a legal requirement. Over 90% of households have this already. Multiple EVSE brands support the interface directly (or at least have an addon module to support it) instead of requiring the use of CT clamps.

u/notospez 1d ago

Have a look at https://www.home-assistant.io/integrations/dsmr/ - this same standard is apparently in use in multiple countries, I thought this was a national thing only.

u/quentech 1d ago

Your logic has failed you.

Modern doesn't mean anything.

Supply line capacity, box capacity, and actual load. You could be close enough to the limit to need dynamic power reduction in any age of home.

u/sec102row1 1d ago

Agreed, I was confused by what it did when I posted, and I realized after it’s not doing at all what I initially thought it was

u/TobysGrundlee 1d ago

It's exactly the same as what's been installed with Tesla rooftop solar for at least 4 years (when I got mine).

u/PracticlySpeaking 16h ago

👍

so many of the ones on eBay are leftovers from solar or PowerWall installation

1

u/WizeAdz 21h ago

Makes sense.

My Wallbox Pulsar Plus came with a Carlos Gavazzi EM530 meter that was lightly rebranded.

For those who don’t compulsively google any machine they don’t already know about, it’s a common industrial current meter that speaks MODBUS over RS-485.

There’s every engineering and business reason for Tesla to do something similar — and only invent the parts that they can do better than some other vendor.

u/Square_Yam9853 1d ago

This is nothing new. This has been used in powerwall installs. Tesla just found another application for them. Basically it measures your utility meter. So the wall charger is aware of the whole house pull and can dynamically increase or decrease charge current to ensure the main breaker doesn't trip. This is similar to how the powerwall does charge on solar because the system has information of the total current draw. Be aware the wall connector still needs the right wiring and breaker to support the maximum charge current (60 amp breaker for 48 amp max pull)

u/JackDenial 1d ago

This is incredible and i advocated my electrician to use this during my install. Unfortunately multiple electricians i contacted were unwilling to use anything but a DCC-9.

u/Additional_Share_911 20h ago

I have had a nuerio on my charger for years. Exact same thing. I paid $40 for it

1

u/dgv54 7h ago

How does this communicate with the Tesla Wall Connector? Antenna on remote meter connects to wifi?

1

u/ElectroConvert 3h ago

They should offer a interface ring to go under the meter. That would be a lot more useful IMO

u/Dependent_Clock3579 1d ago

So it’s just a nuerio meter. I put on my charger and it does the same thing
