Haven’t opened it yet - have to shut the system down to look inside (front cover is interlocked and won’t open while the system is on). Will get to it one of these days

Right - I’ll have to open the Eaton box and see what’s inside. Thanks !

Main panel is inside - what you see here is everything except that - and that is fed from the backup gateway

That makes it easy cause I have exactly 0 30A breakers in my panel

Yes, PW is on and working fine. I understood that PW+ uses a 50A breaker, but I may be mistaken

I'll post some pictures later, but one other thing which may be relevant Originally, my system was specced to be partial home backup with backup gateway - on install day they switched to a backup switch / whole home backup, but left the backup gateway after a few weeks the utility denied the...

There are two breakers in the backup gateway - but those were originally for loads not backed up - which was switched mid install to whole home backup. Those two breakers are both in the off position and as far as I can tell not hooked up to anything

I haven’t opened the safety switch - as it’s interlocked and only opens when off. But I’ll put that on my list to check

Hoping some of the more experienced / knowledgable folks can guide me here I have a single powerwall+ with backup gateway 2 and whole home backup in my main home panel, there are no breakers for the powerwall+, and following the conduit it doesn't enter the main panel at all, instead going...

Yea that makes sense. 2 of those 5 will be in parallel as there are only 4 MPPT per inverter

Maybe he was meaning there are 5 strings in total, across your three inverters - and only one is working correctly that would align with them replacing 2 of the 3 inverters

Well with multiple pw+ you do have a situation where one is acting as the controller. If that one is borked it could impact production across all 3 for example. This could well be software related, or hardware related. Really impossible to know without access to the diagnostics that only tesla...

I haven’t read through all the filings - but yes there are two classes of stock, one for the pre spac merger holders and the second representing the public offering / spac shares with different voting weights As far as the other holders - geelys investment arm is the second largest holder and...

Polestar spun off some time ago and is now a public listed company (PSNY) Yes Volvo is a shareholder but they no longer own it

I’m not sure what you mean by 5 MPPT - There are only 4 MPPTs on the 7.6 inverters. 6 slots in total but 2 are parallel and not independent power point trackers https://www.tesla.com/support/energy/solar-inverter/tesla-solar-inverter What makes you think the software issue is total bs...

After originally being told (in Dec 21) snow mitigation for my solar roof was in design, and I should expect to hear from scheduling soon, this week I was told that there is no solution for solar roof and that any damage claims will be an item for homeowners insurance I find this completely...

I agree with your comments re complexity and that the gateway 2 is mostly redundant with pw+ But clearly the pw+ can control the gw2 - I have this setup and the pw+ is acting as the controller

Yes. Believe so. Thought they could get it through by asking forgiveness. Nope

I’m not aware of any technical reason. The backup gateway was installed first, and was what the plans called for. Then a day or two later they informed me they were changing to backup switch and added it, but left the gateway. Now that ComEd refused the switch it’s back to the gateway only.

My install was with backup switch, gateway 2 and pw +. Inspection failed as they wanted proof of compliance from my utility regarding the backup switch. from there Tesla has been working with the utility (ComEd / Excelon) and have gotten nowhere. So now Tesla came out and removed the backup...

It doesn’t sound unreasonable based on your location, but without more detail it’s hard to say. What is the layout of your panels? (Eg what direction do they face, and how many in each direction?) PVWatts can give you a good estimate based on location and direction of panels, but if you have...

Thron.com is a cdn (content delivery network) that Tesla uses ( domain is tesla-cdn.thron.com - indicating this is thron hosting (distributing at scale) Tesla content) Nothing to do with Canada https://en.wikipedia.org/wiki/Content_delivery_network

If I have time I may do a write up - it’s not as hard as it seems but does require you have some experience with the tools currently. Regarding the frequency - it’s correlated with solar production. When it’s calling for more solar it’s below 60hz and when it’s calling for less production it’s...

This is a grafana dashboard I setup. For data collection from powerwall, I started with liveaverage ( GitHub - liveaverage/docker-powerwall-dashboard: Grafana dashboard showing trend & historical data polled from Tesla Powerwall 2 API served up in an easy to use docker image ) And then made a...

Just to add some more data to the picture. Here’s a graph of frequency - where it was at 60 I was on grid - and when off grid - above 60 is where solar was being curtailed due to full powerwall. As you can see it ranged from about 59.6 to 60.5

Not an expert by any means, so I may have this wrong. But what triggered my line of thought was a webinar that highlighted frequency variation to ‘push’ the frequency. When grid attached this would not succeed as the grid is too strong. When islanded this will modify the observed frequency so...

Powerwall+ here - when running battery only and no solar production, I see 59.6. As solar ramps up this creeps up to and above 60hz when solar needs to be curtailed. from some investigation, it appears that being slightly offset from 60hz helps with detecting and resolving islanding...

The Tesla gateway or powerwall uses Ethernet, WiFi and cellular to talk back to the Tesla mothership (for example to supply your app data about your home production and use) and to update itself if you disable this features will be lost and you may lose the ability to control, monitor or...

Mine was about 4 weeks ago. Currently on firmware 21.31.0

I have a new (non PTO) PW+ , but testing it my PW+ is not configured for this and it appears it will grid export I wonder if this requires the system to be configured with the new software update - I may try that via installer mode to see if I can trigger this self-powered only mode any others...

This option is available in the local ui for your powerwall : gateway with the recent firmware so you can do it that way. You’ll need the local IP address and accept the self signed certificate when your browser prompts you

I saw that go off grid in the release notes, but not in the updated app - have I missed a go off grid option somewhere? (I know it's available on the web UI of the PW/Gateway directly - but this RN implies it's now available in the app - I just can't find it)

To add this is for emergency use so firefighters can reduce voltage on the roof in case they need to enter / ventilate due to structure fire. You want this accessible

I'll add my install to the list of oddities, but now waiting for inspection & utility approval originally spaced to be 1 pw+ with 9kw of solar, partial home backup (ac excluded) electrical install proceeded to plan initially (1x pw+, gateway 2 with integrated panel), then on day 2 another...

What are you connecting the new powerwall to? The plus will get you the integrated inverter but you’d need solar to run into it for it to serve any purpose. Otherwise the battery itself is the same.

For PW+ the password can be found inside the inverter. You’ll have to open the front cover and look inside. My install team also provided this info attached to the back of powerwall leaflet. Use the last 5 digits you see there.
