Good to hear it's worked out for you so far. I'm not sure how Tesla's black box zigbee works compared to SE's zigbee white box, but I imagine they might be similar. On my SE zigbee, it gets repaired with an inverter by hold down a red button until all the lights start flashing. It's then looking...

Sorry to hear that. It took one month from when my third party installer called the RMA in to it arriving at my door step. I actually have a good repour with my installer and I told him I'd install and commission it. He came and took pictures of my work and sent it to my solar company for the...

Yeah I just responded to that post before seeing you referenced it here.

Same here. Woke up to check my PW percentage and couldn't log in. I feel the same way you folks do about the old and new app. I think it's Tesla's way of forcing the garbage new app upgrade on old version users.

I'm assuming you're talking about the Tesla app. I'm having the same problem. Are you running the old or new version of the Tesla app?

I had a 7600 fail in late Novemeber last year. My third party installer came out and got on the phone with Solaredge tech support. As soon as he mentioned VCAP21 failure and that the inverter would not go in to production the Solaredge rep said they'll RMA the unit. It took a month to get a new...

Or a Solaredge HD wave inverter. That would work just as well if not better than the Tesla inverter considering it doesn't need an active cooling system and operates at 99% efficiency.

That's unbelievably extreme IMO, but, to each his own.

In your case, your solar export is specifically controlled by your SE inverters, not by the gateway. If you don't have an SE RGM attached to your system then you can disregard the below information. I'm assuming you have an SE RGM (revenue grade meter) attached to you SE inverters which allows...

Apps back up for me.

It's not very hard at all, but it does require some basic knowledge and understanding of how the TG works and how to get in to it. I'm not going to go in to detail in this forum on how to do it. If you're interested in more information on how to do this please PM me.

Excellent point and I'm sure that's why Tesla has not noticed me charging my PW's ,at will, from the grid on poor solar days for the last 5 months. :cool: And no @jjrandorin, I'm not on some crusade again. I'm just illustrating the point that @Vines is making that Tesla is not looking at...

If you have the none display type SE inverters you can use an app called "setapp". It's the installers app to commission and diagnose problems with your inverter and/or optimizers. Anyone can register as an installer if you have an email address. I'll caveat all this by saying do this at your...

That's a bit of a loaded question there. The number of wires that can be run through a conduit is based on the size/type of conduit and gauge (size) of wire/wires running through the conduit. Then there's the fill/space requirement. The NEC specifications are: One wire: maximum fill is 53% of...

It really sounds like storm watch shouldn't solely concentrate on the individuals geographic location, but also take in to account where the power is coming from to feed individuals and what the NWS says about that geographic location. As an example, if the power plant/substations are located...

Yeah that sucks. Unfortunately, it does sound like an issue with your Neurio module/comms board which you now verified were completely powered off. There's a lot of capacitance in the system to be discharged. That's why it takes so long for everything to completely loose power and shut down.

That's what Teslas cold start/reboot procedure calls for. The big thing is to get the gateway to power off for sure. So 10 minutes or until the gateway is 100% powered off. Or figure out what breaker you're missing to get the gateway to power off.

Did you still have power to the gateway while these were all off for 10 minutes?

You should have a panel with breakers for your PWs and inverters. Did you shut those breakers along with your service disconnect? Shut everything off and leave it off for 10 minutes.

Where exactly is it in the 3.x version?

The older models with the displays seem to have a much higher failure rate than the newer non-display models. I read somewhere that SE had an issue with a capacitor supplier at one point and that was one of the reasons for so many failures at one point. A whole bunch of the display models were...

I wouldn't recommend putting a fire extinguisher near the thing you think will be on fire. I would put it some where away from the PW that is easily accessible. That said, if you insist on having a fire extinguisher for your PW, use a standard ABC or dry chemical fire extinguisher. Litihium ion...

Oh yes, I'm sorry. I don't think I do understand the issue. I apologize for my ignorance in the post. That's unfortunate the software algorithm prevents us from doing this. The example pictured below is what we'd like to being doing. 😞

That is the quintessential statement right there. It's a shame there's no way to take control of our PW's and let them charge from the grid ,at will, to avoid expensive peak charges. Maybe in a distant future and/or an alternate universe this might happen. In my state our "on peak" is 5-10pm...

That's interesting. I experimented with this last year during some off grid ops. I saw that solar shut off around a PW SOC of 97% when the frequency raised to around 62Hz. It seemed to cycle between 96-97%. The inverters would slowly comeback up until around 97% and then production would stop...

There's a really good app called lunasolcal. It gives you all the information you'd ever need about the sun and moons altitude, azimuth, right asc and declination. It shows specific information for your latitude and longitude. I attached a couple screen shots of the app.

It's interesting that you're inquiring if anyone else on this forum has run in to this before based on your technical expertise on the subject already. I personally believe that most people, minus the responders in this thread, have a hard time comprehending what you're trying to diagnose.

That's not even close to exactly what you said. You said you were going to use an isolation transformer. @BGbreeder recommended high voltage probes. Not an exactly at all or even tried to say.

Wow. What a cluster. Sounds like something is wrong with your CT's.

The SE's are all passively cooled with large vertical vein heat sinks in the rear. The difference in cooling between the two is purely engineering and based on the thermal dissipation of the units. Personally, I think the SE inverters are better engineered for cooling. Less possibility for...

In the event of a fire for emergency shutdown you'd shut your main breaker and your A/C disconnect. That's how my system is setup. That would isolate power from the grid and shutdown your solar and take your powerwalls offline for the purposes of providing power to your house.

I would hope not, but anythings possible. I'm pretty sure the prongs are far enough apart that you'd have to intentionly stick some sort of conducting object in there to make it arc. I've seen my local utility change my meter out three times and those guys have no issues pulling and replacing...

If we're talking about only one main power meter for your house, then as soon as the meter is pulled from the socket, the gateway 2 should island your house when the relay in the gateway separates your house from the grid, i.e. the load side of the meter socket. This would happen with in a few...

Agreed. The inverter clipping will only give him 13.6kW, but why is he only getting 11.6kW now? Even with a 5% loss of efficiency due to heat, that still doesn't add up to the extra 2kW he's still loosing.

I definitely agree that heat could be a factor for the OP's panels and that could possibly causing the dip in performance. I'm not sure if it would be that much based on the size of the OP's system. The OP must be running a 7.6kW and 6kW SE inverter to get his initial 13.6kW.

What's your point? Boasting about the size of your system and it's capabilities has nothing to do with what the OP was asking about.

Agreed. I wish the OP would chime back in with their thoughts on what they've seen thus far in this thread and what they've decided to do.

Normal. I can only speak to a gateway 1 but I'll make a safe assumption that the gateway 2 is the same.

I can't really speak to what you want to do, but I would consult an electrician about your idea and see what they come back with.

No worries. Thank you for replying.

I stand corrected. You never did say that it cost not much more than $700. My 7500W generac generator I've had a few years now did cost around $950. So I'll bump the total up to $1650. What is your definition of "They were not that much money."? I would think a setup like you have installed...

Well, either way, the way I have it setup now is legal and safe and in the event of an extended power outage, it still allows the PW's to charge from PV during the day while the generator can run my house separately.

@h2ofun Wow, so you have a 22kW generator with 2 ATS installed on two 200 amp subpanels for not much more than $700? That's impressive.

I don't see how I'm misunderstanding the generator connection. What you're saying, minus your last sentence is exactly how I installed the MTS. Did you even read what I wrote before making such a statement? It is true, I did not realize there was an ATS configuration that would activate in the...

Ah okay. I'm sorry. I think I misunderstood you. I'll be honest, I did not realize there was support for direct generator configuration. I would think for sure that the inverters would have to be off as tug of war would occur between the generator and the inverters. I would think that'd you have...

All true but an ATS/generator setup would be significantly more expensive than the manual setup above.

It's no so much that the generator doesn't exist it's that the gateway doesn't perceive there's any load on the house when the MTS is in the generator position. Which brings us to your second point about the generator not being able to charge the powerwalls. Since the gateway doesn't see any...

Great! Thanks for the quick answer @jjrandorin. Disclaimer: I am NOT a licensed electrician in any way, shape or form. Those that are DIY'ers and would like to repeat what I'm showing you please do so at your own risk. I won't be held responsible for anybody who injures or kills themselves or...

I'm not sure if there's something similiar already as a forum topic. This OP did discuss using a generator as an intigrated feature so me posting about it here showing how you can do it with the Tesla system might be appropriate. @jjrandorin Would it be okay to post my setup of a manual transfer...

Same here. I wired a manual transfer switch between my gateway and my backup loads panel. I can run my generac 7500W generator to power my entire backup loads center and allow all the sun to charge my PW's during the day if need be.
