Sounds like poster might want something like this : grid goes down, hut tub running, kill hot tub. Could try a relay attached to somewhere on the supply side of the gateway (E. G. Feeder) with relay (NC) output run to a shunt trip breaker installed for the hot tub. Use opto isolator or whatever...

Sounding like Tesla has created even more naming confusion than needed with the Powerwall plus. Sure looks like the "plus" is a essentially a pw2 (it has same base partnnumber?) with a PV Inverter added to it for some amount of array (maybe up to 7 or 8kw of panels.?) Also sounds like they...

As far as I can tell, the Powerwall is able to charge from grid, completely software controlled by Tesla. The issue is what the utility company and or state regulations allow. With calif/pge, and if you have solar array, it seems the only time they want you to charge from grid is for an...

Sorka, he's describing a Delta inverter, not SolarEdge. E. G model M8, "mtool" app to connect via blue tooth.

I never saw an actual notification when the gateway 2 firmware updates itself. It even downgraded once a few weeks ago, then later updated to a different FW version. Never was any notifications. You can see the FW version by either logging into the gateway directly or its shown, as bmah noted...

It seems telsa is wanting to replace the util Co meter now, without even telling the utility about it? This backup switch appears to be completely in place of the electric company's meter. I guess if I was the EC I would be thinking 'no way' too...

This thread smacks of "pge people are confused by their own overly complicated rules"

Tesla may be creating yet more naming confusion. I have 3 of TPN 3012170. There is no indication that it has additional built in solar inverter or 4 mppt. Which is what this link says a "Powerwall plus" has: How Powerwall Works | Powerwall Support Could it be that they actually mean "when it's...

in that top image your panels look like they are pointed pretty high, even for summer. try a solar angle calculator, heres one link: Solar Angle Calculator put in your location to the calculator to get the angles. I think you would want to put your panels closer to the spring/fall angle if...

My graph has never looked as good as that June 6th you posted, nor have I ever hit a total kwh daily that is that high. The "yesterday" graph is more like most of my days. It looks like your array is not putting out as much as mine, but it's angled lower too. Mine is at the roof angle which is a...

Can you elaborate on the "associated inverter" pls? Did they install the new telsa inverter instead of e. G. SolarEdge or Delta? Maybe post a picture. And what is the model number of the PW, e. G. The "TPN" rather than the top label showing 2.1, etc.

In the upper right of your picture is a rj45 connector, just to the left of the 4 communication terminal blocks. Connect your ethernet cable to that. The gw2 defaults to DHCP and will ask for an ip addr from your home lan/router. The gw2 will still stay also connected via wifi, and cellular. So...

Good Deal:) glad to see "escalation" worked for you :)

I wonder, M professional version differences too?

They do that because the harder it is to add it up the easier it is for them to charge ppl more :P

All i can say is MAKE THEM SHOW YOU the the equipment they'll install when their truck pulls up. they wrote up my layout and even had approved planset with Solaredge with inverters, and optimizers for my property with multiple shading issues, and day of? ... they install delta, it...

The generic "purchase agreement" they used says bill due in full when building inspection signed off. at least a couple people on here are stuck months between the inspection done and not getting PTO with utilities. personally i am stalling the inspection til they put the inverter in they...

I think Powerwalls (PW2) are really good pieces of equipment (i have 3 in my garage now). The GW2 is decent too (except that they are trying to limit local net automation connections more now, which stinketh, and a couple other complints regarding firmware). No other whole home battery system...

@BGbreeder might find this useful.

between @aesculus and @gl123 2 differnt notes about the firmware and behavior, the "cutting out" is probably not just firmware version alone. (my delta M10 with sys FW v 2.2.13 does it a number of times a day). se my post earlier today, i suspect its possible for us to try different version of...

learned a little more about firmware and "little black box" monkeying with it the last few days (started by getting a powerline etehrnet adapter for lan, so i could plug neo in right next to the inverter last week; this week been monkeying with what i can learn). Firmware @lucassaugen : the M...

Same experience here, mate. its like most things you do with a tesla person fall into a black hole.

The tesla contract i signed back in 11/2020 says you owe them in full when the BUILDING INSPECTION is signed off, not the PTO.

Sorry, no good idea how to push tesla to move. I've been partly installed and back and forth with them since February. Based on the numerous "contacts" with them, I suspect there are a lot of hangups and delays inside tesla. With them just dropping the ball. They installed a different inverter...

If you have a powerwall + white "backup gateway2" then the production data is NOT via the little black neo device (neo is then used for e.g. remote firmware upgrades on the inverter as far as i can tell). If you have solar only, then tesla/mobile app is getting data from the black box. Sorry...

you need a firmware bin file physically on your phone to satisfy the M professional app. I have searched for a couple hours around delta sites, and web at large, but found no where to get firmware downloads for an M10-TL (or M4, 6,8, TLs either)

i have this little black box, it currently reads "no server" and "no signal" in red on the front. its probably 20-30 feet away from the delta inverter. i never knew what its for and the installer had told me that location would be fine :> guess i need to try to troubleshoot it, get it closer...

My city accepts and approves plans from tesla /without/ my agreement unfortunately. City did notify me when a new plan was submitted (I have an account with them). When the inspector came (tesla arranged that) and i explained to him what happened, he marked it "not ready." So its still dangling.

Part of the sleight of hand re the agreement, layout, and inverter change is that the purchase agreement and layout are separate documents. They try to be generic in the agreement, which they try to get you to sign before knowing what theyll actually do. I didnt sign that agreement first. i...

hi sorka. I have the customer layout saved, it shows SE inverter. I re-downloaded it just now from my account, half expecting to see it mysteriously changed. It hasnt. I havent agreed to (verbally or esigned) anything since late 2020 (when it was suppsoedly SE). The gory details are in posts...

If that's all we'd have to pay on our end (end user) extra to get those features, I'd pay it. Small price (36x $30, or even 36x $60) to be able to pinpoint issues later down the road. Sort of like an insurance policy that only costs 2% up front for life. I've already wasted more time on this...

No, I havent given them the check yet. I am surprised they arent quicker to try to get it from me. I told them we need a resolution first. It's definitely been a learning experience over this. I should have been more concerned about checking if they were going to do what we had been...

thank you, dareed. point taken: firmware could be a big issue, and the parallell strings alone would not cause as much problem as i am seeing with shading.... (i am seeing essentially complete drop out of the 24 panel doubled string set when only 1 panel of it is completely covered.) I will try...

I found about half a dozen approved plansets on the web, for solar roof with delta inverters. Everyone of them used an "external Bypass diode" attached to each and every roof tile. I suspect this can make the output the inverter sees look different. These harnesses with external diodes in them...

This is great information guys, defiante Thank You's to @nwdiver @dareed1 @cali8484 @aesculus . Should I send these screenshots from "M Professional" to Tesla people? Will they be telling me something like "you shouldnt be logging in with that app! only we can!" ? I did manage to get my...

hmm, it is a notable differnce from firmware. what had to happen to actually upgrade the FW? inperson (3 ft away to get blue tooth) or remote possible? if remote, do you have to bring local ethernet to be hooked up to it?

@dareed1 and @nwdiver Here is my attempt to get yesterday’s (6/15) history of volt/amp graphs out of my delta M10-TL-US with one of versions of delta's mobile app (Mtool itself on the apple store or android was hardly helpful, i was able to find via a archive site mtool prof (M professional)...

@nwdiver , can you be more specific about what form the "string data" you are referring to should be? voltages output from the inverter? i dont have any system to monitor panels, the delta system has no way of providing that. ... measured levels on the roof? an array connection map and shading...

@dareed1 The the second installer that came to check ( took the array apart and cehcked the wiring), he gave me an array map, and showed me where the two portions (the left 12 and right 24, joine dn roof) are coming separately to the 2 mppt terminal blocks in the inverter. So I think its...

Here's a bit more info about how the Delta inverter behaves/reacts. This picture is a recent (6/14) day's pattern where there was wispy clouds passing by off and on in the morning. Emphasis on "wispy"; very thin. (there is no shading in the mornings, at least not for the past month or so, the...

The reason I posted this second level of detail, is 1) i feel people should know how this colar contractor space could play out for them, and 2) the kind of production behavior that might happen if this happens to them. Originally i was hoping for ideas how to contact teh right kind of people...

Confirm, yes theres are only 2 blocks to tie into in the M10 inverter, no option to up it (one thing the guy i just mentioned was grumbling about) the M6 and M8 both have 3. data sheets list 2 mppt for m10, 3 for 6 and 8. I bet its not the appropriate inverter for the situation, and i posted my...

yes the array is 3 strings of 12, see the roof picture i posted it has colored lines arounf the 12 and the right 24. the 24 are joined in the Jbox in the upper right corner of the picture. also, yes it clips at 8.8kw roughly. total out drops to about 5ish when some of the first 12--panel-string...

@nwdiver suggests that all panel modules will effectively gracefully degrade when combined into an array. The behavior by MY array (described in 2 posts here) is consistent with SE's descriptions, not nwdiver's. With all due respect, as some of the things i have read from you in the past have...

Yes i joined hoping to find some tips on how to help me get some resolution. Sorry I am pretty busy with work and the projects going on at my properties, or i would post more often (or maybe if i was still as excited about getting a PW+solar system as i was before this "game"started). See below...

There has been no resolution, nearly 4 months after install. Tesla has largely ignoredmany many contact attmpts after switching to a Delta M-10-US inverter/no optimizers, not as promised and has seriously poor production issues as detailed below. The short of it is that minimal shading, with...

A couple weeks ago, we had install of a 11.8kw panel set with 3 powerwalls completed. While I was promised a system power optimizers for shading and a solaredge 10k inverter (both verbally and was on the planset in 11/2020), what is actually installed has no optimizers and a Delta M10-TL-US...
