I don’t think there is any electronic needed in wall connector for v2h, other the powerwall/gateway and charger installed in backup panel. Charge on solar is independent of cable.

Are the fans to cool the bus bars, or electronics?

The battery pack is to small for towing. Every truck that tows daily will need the battery replaced about every three years. I base that based on cars that were designed with less then 150 mile range, battery can’t handle it. I probably have three years till my order comes up. I will deal...

I won’t execute my order till tesla offers the 500 mile battery. I think towing with the 300 mile battery will “damage” the battery due to the every large sustained load. So life won’t be great. Then tesla will start denying claims because people didn’t buy the range extender.

Panel V, generation panel, has a main breaker which will disconnect it from the TEG. I believe you are correct and the batteries will shut down when the main breaker is thrown, but have not tested it. I believe the fire department will look and open every thing labeled emergency disconnect.

What is the difference between 1 and 3? Line diagram is correct, even has main breakers in 400 amp panels. I added labels to pictures.

What about the ecoflow generator which puts out dc 48-58.8v and connecting to solar inverter to charge powerwalls. https://us.ecoflow.com/products/dual-fuel-generator?variant=40573814014025

I think Tesla screwed up my panel labeling. Need to know what the experts think. I have a 200 amp disconnect switch outside between the meter and TEG, I think should be marked “Emergency Disconnect, Not Service equipment”. Then I have a generation panel outside that goes to the TEG combining...

Ok dispatchable then. You have to divide solar, 2 axis tracker, by three; and fixed by four. And that is one the best sunny day. Texas, ecott, is trying to figure out how to use grid scale batteries, what has been happening is just seldom peek shaving. Texas might have 5 GW of installed...

let’s say the charger install costs 10K, can the OP get a tax credit on the installation? And how much would that be? Install might require more then one trade, concrete guy to cut concrete and replace, electrician to run conduit to main service panel and materials. Would add value to said...

perhaps if the base had wings to pick up stud.

Long term storage should be below 86F, PW2.

Is it just me? Data dropout in Tesla app but not in PW Dashboard. 5.9 KWh missing energy.

My insert has fresh air inlet on the sides, Glass helps slow the flow up the chimney. Vertical has the benefit of self clearing snow. Tilt of earth is 23.6 degrees, so that is 47.2 summer to winter. Vertical is the equivalent of north facing panels in summer as vertical to winter. I’m not...

I would like to toss out my existing hvac, but for a few week out of the year it does what it needs to within my energy budget (solar production). To replace three systems would be expensive, $30K plus. I will keep fixing what I have, I do my own work. I have regular fireplace insert with...

And battery longevity…

I couldn’t survive off grid without supplementing my heat with propane/wood. If it is zero degrees out I use 200 kWh per day with supplementing with fire place, and on a good solar day I can generate 80 kWh in winter, summer 130 kwh; but I can’t count on solar in winter. If I shutoff the...

Littleton, Colorado Westfield UTC Mall in San Diego, California San Jose, CA Bethesda, MD. https://www.tesla.com/findus/location/store/montgomerymall Please add to list, keep on topic of showroom locations only. For those who want to go see one in person.

First release is small battery. Get over it, big battery is coming later.

Baloney sandwiches?

Still 1GW of solar is still one third the kWh of a nuclear plant on the best day!

I believe the car has a CT, for feedback on charger draw so as not to over draw from charger/circuit limitations. But agree something goes to sleep. I have an access point in garage, so WiFi signal strength isn’t the problem.

I was charging on grid, since the prices was negative! We, Texas, are generating 24 Gw of wind!

The data for the car drops out, and then is reported as a 126 kw load, charge on solar was turned off and charge rate was set to 16 amps. Seems like the car stops reporting to TEG, car dropped out in bottom graph half way thru charging, then comes thru at end as huge number. See graphs; car...

Tesla have battery packs manufactured in China sold in China and now in the USA. So the teslas could be China batteries. I do not like 100Ah prismatic batteries in electrical vehicle battery packs, if a cell short occurs there is no fuse to blow possibly stopping a fire. Tesla battery packs...

So with pw3, if your solar is unevenly distributed across your powerwalls, will it charge the remaining powerwalls through ac coupling? Can PW3 be integrated with existing solar?

Seems like it is dead! WiFi access point TEG- should always be broadcasted. Did power cycle fix anything?

Production dropped to 2.1Kw.

If I was tesla I would not want to produce pw2 for the next ten years to cover warranty claims and pw3. I see no reason why pw3 would not be capatible with pw2.

Kill app and restart

Energy reported by car in app (391 kWh), by Powerwall (415.9 kWh), and recorded from Tesla installed neurio (432.3 kWh) all different. Data from month of August. I have a Neurio in non backup panel, only loads in non backup panel is the evsc and heater circuit. So I believe Neurio...

https://pvwatts.nrel.gov/ I would probably add 10% to that for aging and probably more for expected usage changes.

Where do you find this report?

Do you mean 98% curtailment started and back on at 97%? What is your graphic? Looks like something from your utility!

I decided to leave my ground to neutral bonded on my portable generator (12kw). yes I realize I now have two parallel conductors which in my opinion is safer then someone using the generator not realizing the bond doesn't exist to run power tools. I will eventually pass away and someone could...

Profile: Ieee 1547 GW 61 to 62 hz (1.2.1)

My powerwall are set to 2.2, or 62.2 hz. Is there a spreadsheet of all the grid profiles for enphase?

I think they were lazy. My house is grounded to cold water line and one ground rod, built in 2002. Now they require UFER ground, so perhaps the electrician took a measurement and determined it wasn’t necessary. But I’m thinking of adding two ground rods and landing them in the main generation...

Tag is confusing, seems like different inverter options. So is Bess output dependent on inverter installed? Charge limited to 5KW. I’m sure batteries cells are CATL, prismatic. LFP likes to be charged to 100%, so that is a good thing. Still prefer cylindrical cells in metal can. So now...

Installs have started. Anyone have installation manual link, geek p0rn! https://electrek.co/2023/09/08/tesla-starts-powerwall-3-installations-looks-worse-more-useful/

I have GE panels, originally two 40 circuit panels, and replaced my backup loads panel with a 80 circuit GE panel so I could fit all my loads into it. If you go this route ask Tesla to install 3/0 wire, it can handle 200 amps where 2/0 can only handle 180 amps. I installed the 80 circuit panel...

Im certain that 83hz is a typo, s/b 63hz. Iq8 inverters can act as both a current power supply and a voltage power supply, but they should never go into voltage mode unless connected to enphase gateway and commanded to do so. But seems like they did and weren’t able to charge powerwall. But...

I have iq7 inverters and have been running on the IEEE 1547 default profile, but would a soft curtail profile for when running off grid. I wonder if your issue is a iq8 only issue? Are you monitoring frequency while off grid? That would be the only powerwall “input”. Seems like the inverters...

Charge on solar is having issues, car say it can’t connect to powerwall. Powerwall dashboard is working, so powerwall is on my network; car is on wifi and communicating. So something is a miss with tesla, I don’t think it is on your end. Can you vpn into your home network and troubleshoot?

Resurrect old thread….

I think the 200 bucks covers both federal and state. But state isn’t giving the feds their cut. State says they would just get it all back from the feds anyway.

Texas has done away with inspections!! So that will not work.

I drive my MY about 10,000 mi per year, I have other vehicles. Also not all mileage is driven in Texas. I think this is should be by gross weight and equivalent mileage in gas.

Open the door, where is the leak coming from in inverter.
