From what my installer says it's a new offering this year, same hardware just not fully integrated (have to run the power + comms). It's described on the order as "Tesla Powerwall+ with inverter".

Not possible with the conduit that was run - it's already maxed out with the battery. Nothing, but that's the same as any other electrical or natural gas appliance in the entire house. It'll be mounted on a concrete wall and the ceiling is sheetrock. Unless there's some fire safety concern I'm...

See, I posted this and knew it was going to cause confusion... The battery will be in the basement - much more temperate which will make it happier. There is no fireproofing consideration other than it will be hung on a concrete foundation wall. The question I have is for the inverter. It will...

After a bit of a hiatus, I'm back! We recently moved into a new home and am getting solar installed now. Exciting stuff but I could use the help of the forum for a question that just came up. New home is in a location where mean maximum high in the summer is 95f / 35c and mean minimum low in...

This is good news! Question: if you go off grid while the Powerwall is full and the local frequency goes up, does that screw up your powerline adapters? I ask because the old TP Link adapters I had seemed to struggle when the local frequency was 62hz+...

I read through the thread and may have missed it - @crackers8199 did you have the TEG forget your wifi network? I had to do so in order to get the ethernet connection to work consistently but it has been rock solid ever since.

Wow - that's super crummy but thanks for the update. I'm seriously considering PV + battery in my new home but after reviewing the other options and seeing these sort of stories I'd likely not go with the PW again.

With just how poorly worded this note was alone would cause me to ignore it, let alone deeply question the SA's general ability to provide competent service... What exactly does "back fed power surges from the Span IO if there is a power outage" mean? I did some research this morning and found...

Good journalism is supposed to be dumpy. I expected better from the AP than sensationalized articles. The grid was going to be unreliable regardless of any change in weather events and more people will be effected as, well, there are more people. Here's an actually decent article from USA Today...

Argh, I used to have so much respect for the AP and all of that has gone so far downhill with this pseudoscience explainer journalism... Yes, of course, power outages are more frequent - we have an aging grid, more people, and more demand for electricity than any other time in history. But to...

I have 1 Powerwall with 8.6kw of PV. Max I get during the summer peaks is about 6.3kW, which is still below the PW2's 7kw surge limit. If you don't want to buy more Powerwalls consider restringing your existing + some new to the single Powerwall and the rest to the non-backed up side. I don't...

Yes but I was not expecting $220k expensive :)

Looking to build a good sized new home with a large and complex roof. The quotes I've gotten so far for a Solar Roof are...well they're high. Just curious if anyone else has gotten a recent quote to help me understand if the area we're looking to build is marked up or if these systems are...

It's not a contest, but you're winning.

To my amateur that really sounds like a large breaker opening. Strange that its that many though. No smoke, smell, or anything else?

It's a Calix P-Series 711GE. Was installed in 2017. P-Series

Everything in my home except high wattage circuits (L2 EV charger, AC, electric dryer, and oven) is backed up so anything that is sensitive to blips is on the Powerwall. I have 5 UPSes throughout the house because I'm an addict. - 1500VA for my PC and monitor - 1000VA for the networking closet...

This is all I really want. The Powerwall is nice and all, may even still want them in my next house. Having a 60kwh+ or two battery sitting in a garage most of the day is such a waste. Bonus points for a PHEV that can double as an emergency generator during grid outages. This is the future...

To add to this - it's almost always the AHJ that dictates what your Powerwall's grid profile is which is then enforced through the interconnection agreement.

Staying over 62hz after the Powerwall is under even 90% seems excessive. Glad you're at least making progress, your approach is correct! FWIW my max frequency is 62hz and it drops to 60hz when the Powerwall is at about 93%. Note to all new Powerwall owners to test this scenario fully before...

I haven't looked at the Tesla Cloud APIs but the local APIs return what location was set during provisioning. My local config was correct (right zip code) but Tesla said they had it wrong. No idea if that means there's something on their end that we can see or not, I just know it works after I...

Yes, strange but quite normal. Mine does the same: drops to about 96-98% through the night then charges back to 100% in the morning when the sun comes up.

It's possible Tesla has a misconfiguraiton on their end. My Powerwall did not get StormWatch alerts at the beginning even though, through this forum, I found others in the same county as me getting the alert. I complained to Tesla and they "fixed the glitch" on their side. My best guess? They...

Was putting a dust cover on top something Tesla suggested? (guessing not since you said Tesla Support was not helpful and you said "I decided"...) The Powerwall is IP67 rated meaning its dustproof, though the wiring compartment is IP56 meaning dust resistant.

I use the "PREPA off‐grid frequency‐watt 83/Hz" shared from this post: My grid outage frequency issue is resolved!

Same here. Called Enphase and had them apply a profile that adjusts PV production based on local frequency, much nicer during an outage.

Stolen from my Reddit post of a similar nature... Ensure the Powerwalls are mounted above any flood level. If you're at risk of hurricanes and tropical storms: the Powerwall has an IP rating of IP67 and IP56 which is very good but it is not immersion proof "IP8". Tesla probably accounted for...

Water and soda/energy drinks is a good call. Not our solar crew but we had some back yard work done and a 24 pack of water, Gatorade, and cokes went far. We noticed the crew drank a lot of Monster so we picked up a case of that as well. It's a small gesture and the crew was already fantastic -...

It's expected behavior that, without being charged through PV or the grid (stormwatch or otherwise), Powerwalls drain at about 3% a day. I see this with mine meaning about 15w draw. 5% per day or 59w seems excessive though.

Right, that's something I'm not familiar with. If the SunnyIsland is UL1741SA/IEEE 1547 complaint there shouldn't be an issue (because that's why the standards exist!)...

Just adding on to this: in theory any complaint inverter will be able to be configured however you'd like. Since the Powerwall is grid tied and your inverters are "behind" the Powerwall from the grid's perspective the AHJ almost certainly doesn't care how it's configured as long as the Powerwall...

I actually tested this last year and found that my frequency went from 62hz at 100%-95.4% SoC, to 61hz at 94.3%, and 60hz at 93.4%. YMMV.

Are you in backup only or self powered mode?

Seems like expected behavior. What was the Powerwall state of charge when you pulled those numbers?

This is not always the case depending on your system specs, configuration, Powerwall state of charge, current PV production, and the type of outage. In some, maybe most, cases the transition is quick enough for sensitive electronics. I've personally experienced outages that take multiple seconds...

I have 5 in my home for all of my various and sundry electronics. Yes, I have a problem. :)

Spec and configuration can be different. In the USA, IEEE 1547 was established as the grid interconnect standard by the Energy Policy Act of 2005. Local jurisdictions may differ slightly but by and large any grid connected device in the US since '05 should be compliant. 1547 establishes limits...

65hz is unnecessarily excessive, it screws with so so so many things. LED bulbs will flicker Induction cooktops don't work AFCI/GFCI breakers will trip Anything motorized will run fast (garage door opener, vacuums, furnace blower, etc) Powerline ethernet adapters stop working Home automation...

Since your observation is specifically about ARP this may not be related but I had 0 luck keeping my TEG connected to my Unifi network (regular AP system, not mesh). I eventually just ran cat6 under the house to the TEG and disabled the wifi, been working great since. That'd be my #1 suggestion...

It's a little bit more complex than that. You have to have the Storm Watch functionality enabled in the app AND a Storm Watch must be initiated from Tesla's end likely using things like NWS alerts. Flipping the Storm Watch switch in the app doesn't automatically start charging you from the grid.

That's stupid. OP's question is legit, I thought the pairing was to help address that!

Wait...doesn't the "pair this device with your Powerwall" make it so your phone can get status directly from the Powerwall without internet? (seriously asking - I haven't set it up yet). https://www.tesla.com/support/energy/powerwall/mobile-app/go-off-grid

Correct. I have mine set to 100% reserve and it functions the same as "backup only". It's unfortunate that Tesla simply didn't update the UX to show that sliding to 100% means "backup only"...

My experience was pretty straightforward - called, escalated to T2, explained in two sentences the problem and the ask, ticket filed, changed within a few days.

This would be my guess too. Checking if the Powerwall is set to 65hz is easy enough through the API.

Not SDG&E specific but it happens that local transformer capacity and load projections limit how much power can be exported. You may be able to get a more complete answer from SDG&E about why the limit is there and if it's due to capacity concerns on the local lines and transformers see if they...

Navigate to https://<powerwallip>/api/site_info while logged in to your TEG locally you'll get a reply that should include "grid_code_overrides" with "soc_freq_droop_config_df_max". The value there is the hz increase above baseline...

Curious what does the API say?

Same - 3rd party installer, had to call Tesla support.

Do off grid testing and get them to update your max off grid frequency to 62hz before the installer leaves. Try the system out with full sun, full Powerwalls if you can and see what happens when you cut grid power.
