Hadlock posted:Amazon sells a leviton combo smart plug + GFCI for $29 I've already ordered Is it all on the same circuit? You mentioned only having one outlet "on that side of the house/garage/something" - you only need one right where the circuit first starts from the panel assuming it's a home run from the panel to that outlet. Then you're good to go for the whole circuit. Or use a GFCI breaker. I wouldn't bother putting your fish electrolysis machine on a GFCI yet though - it's just going to trip it. (I'm suggesting you throw it away or move it indoors first.)

Something, somewhere, is leaking current to ground. You can pay an electrician hourly to solve this. It's around $1000/day. Next step is to unplug everything on a given breaker, but let's start easy. Do you have any 220v appliances with 3 prong outlets? Unplug those and see if it goes away.

internet celebrity posted:My only appliance with a 3 prong 220 plug is my dryer and unplugging that and/or shutting off the breaker doesn't affect the reading or the noise whatsoever. Should I unplug all the appliances and everything on each circuit repeat what I just did? I feel like it may be related to the basement light/outlet wiring given what I've seen so far, that breaker causes the biggest change and makes the most EM noise. There are also a few (unused) ungrounded 2 prong outlets on that breaker. Yes, start with the biggest change and work from there. 2 prong outlets shouldn't be effecting it - they don't even have ground. 3-prong-220v can leak voltage L1-G to power the 120v control board is why I suggested it. Otherwise yeah, start testing. Have a laptop with a video camera? Setup your meter on a zoom call. Join it from your phone. Unplug things and watch it go until it auto shuts off and you have to go turn the meter back on.

  They were finally able to get started on this today! Nothing is wired up yet, and they have 3 more batteries to install Monday pending some change they have to ask the fire department about. 2 of the battery modules were supposed to go on the block wall to the left but some last minute measurements realized a mistake in their initial ones. Now we're going up. They need to verify the vertical clearance required by the FD - Enphase (and UL) say these specific modules can do 6", standard plans/prior generations required 36" or something. I don't care how high they go, that's my neighbor's and the electricians servicing them's problem.The hilarious wire coming out of the conduit in the ground there was a whoopsy doodle once they were done moving the main panel and couldn't figure out where the heck the pool pump was getting its power. It will be cleaned up / figured out by the time final inspection rolls around. Yes we have gotten 3 feet of rain so far this year and yes that is a NEMA 3R rated splice, why do you ask? What are you a narc?

I guess it's to guarantee to input voltage from the batteries while working on the controller? On a high level I understand wanting a visual indicator that 20kwh w/ 30kw output is isolated in case the internal controllers decide to start outputting despite an ordered shutdown.

Yeah, my plan if this stuff decided to poo poo the bed was to immediately tear that sticker off and make sure any actual technician who showed up knew it was intact when they arrived.

 City or FD said "no" to close spacing, or they got bored waiting. I do not care and had told them a week ago they could do this if they wanted. I cannot see this from any direction I use the house, there are mature plants blocking the view from the road.  So close. Final hookup + testing is monday or tuesday weather permitting, final permit inspections are all Thursday at which point I can submit my PTO. I need to find out what they did there with that WR GFCI outlet which is powering the pool pump. Ironically if they wound up wiring it into the controller to go "down" when the grid goes down that would be hilariously ideal.

8am yesterday: Whoopsy doodle, warehouse apparently picked a Gen2 controller instead of the Gen3 it said everywhere. No one noticed until (I presume) they went to fire it up with Enphase on the phone. Electrician calmly and politely and definitely without any swearing worked it out with the warehouse and tada:  Seeing them side by side no wonder no one noticed until they saw it in the software. At 1:00pm I swung by and:   I'm insufferably excited about this. They broke for lunch literal minutes before, because the meter ticked over from 2 to 3kwh exported, which is 20 minutes of generation. I went and turned on the heat pump + pool pump in celebration. Inspection is Monday for all 4 open permits (HVAC, Electrical MPU, Electrical Battery, Solar Generation) and they're also going to integrate the batteries then. It's all wired up but they're off pending registration. After that they submit for my PTO. Fingers crossed. And they are in communication with the field office re: exporting, once the application is accepted pending inspection they don't care if you run it for "testing" while pending the PTO, they just won't pay for the power. My meter is on "the list" now. It's tempting to go buy a 7.82kw level2 car charger for $300 and just let people charge their EVs while the sun is shining until then. gently caress em.

Extant Artiodactyl posted:all the time i had the warehouse pick gen 1 for gen 2 (or powerwall 2 for powerwall+), but honestly mounting the thing is too far along in the process to not put some blame on the electricians. they had to ignore tons of papers taped on to it talking about incompatibility and the the fact that there aren't hardwire comm ports anywhere in the gen 2. it's something you should pick up on as you're planning the runs but all's well that ends well. it's up now. they just have a pre-drilled gen 2 controller This seems like something I would do on my zillionth install. Why would you be reading all those papers? They definitely share some of the blame - they should have inspected their pallet before signing the BOL at delivery - but looking at those two units which I've probably installed 50+ of in the past year? Those papers are all getting torn off and tossed. When you expect something to be correct it's pretty powerful. Maybe they've otherwise been lucky with their distributor picking the correct units? (lol)Plus: devicenull posted:That's on enphase IMO - they put loving cling wrap stickers on your batteries, they can't do one on the front of the controller saying "this is a gen3 controller"?

 I just went and killed the breaker to the utility meter in total darkness and the lights stayed on! I went and charged up my laptop, connected to the Envoy wifi, found out my spectrum modem is fried out, and fired up the heater! I was cozy and warm and basically giddy with excitement being isolated from the grid. I didn't leave it like that since I can't actually track the charge yet and don't know how much they have on them so I normalized before I left. Sadly the default webserver on the envoy system is actually baseline secure? So strange. Sadly it doesn't show any metrics without a login. Clever though, they allow signed tokens to get you in.

I thought they all needed to be grid-tied (as in, be receiving 240 from the grid) to actually function which was why they were basically worthless. Or is that just the microinverters and you have an actual inverter? The feature you need is a "Neutral Forming Transformer." I have microinverters, but it was pitch black out. This was the batteries firing up.

Extant Artiodactyl posted:that's a big gently caress-up. it probably cascaded from the equipment mistake leading to redoing all the connections of the system controller. 100% that's when it happened.

It's all words at this point, but if they can't source the board on my KitchenAid KEBK276SSS 27" double oven with bread proofing, hidden element, and other interesting features it's going to be what's at a glance looking like a $4000-4400 retail writeoff.

This never gets old. It was cold out so I flipped on the heater for "free" this morning for the 2hrs I'm going to be here. Fire inspection and presuming that passes city final this week. City has already verbally approved it but they changed some SOP stuff in the past month to re-order some things so their final is after FD signature, which makes sense.

Yeah I don't know yet what I am going to be doing in average usage so I will need to tweak it potentially. I do not have grid sale mode enabled yet but around here it should in theory help prevent rolling blackouts with enough participation. I downloaded the export pricing spreadsheet but can't make heads nor tails of it. Plus I can't tell if they actually cut me checks with nem3 because of all the bullshit. But I do know for a few hours a day in August / September I see like $2/kwh export rates. Ironically when it's most likely above the operating temperature of the batteries... Right now I am consuming like 1-2kwh/day from the grid and exporting a ton. Once we move in that export number might flip. My daily generation on a cool sunny day is 70kwh. How much have you seen that reduced in hot summer months?

Extant Artiodactyl posted:in this area, summer always beats winter for production. enphase had specific training for installers in the cali market but i never took it. I assume summer will be higher most days, but we get a few weeks of truly awful temps here. Just curious where we're going to wind up. Thankfully it's north facing and so should be out of direct sunlight by the worst hours. FD came by today and blessed the system. He said it was exactly how he likes to see them. I spoke with him briefly as he was saying this is how he would setup his system, all outside, away from everything. I told him how "I want it outside so I have a chance of escape before it burns the house down." "Exactly. Escape time is much higher outside." He said they generally only see them burn due to damage, they only see damage in garages/driveways, and 3ft of clearance does nothing against a modern SUV/Truck. Overall made me feel really good about my choices and insistence on design and location. Apparently there are some sketchy contractors who try to get all the shutoffs inside... right next to the batteries. Apparently he just came from a re-inspection where the job site looked identical to the initial inspection. I would not want the level of scrutiny that amount of disregard for a punch list would result in.

TooMuchAbstraction posted:However, I will stress that those experts are used to communicating with homeowners that don't know anything about how their house works. If you come to them with more technically accurate language, they may well not believe you, and they'd certainly better not trust you (e.g. when you say that an outlet isn't receiving current). In addition - If you are confidently wrong you can wind up causing frustration for everyone. The second part of this is the goldmine though - knowing enough to be able to do the full consumer-side troubleshooting workflow. That being said, the book suggested is a great resource, which includes some of the worthless physics -> real world conversions. The other element of it is mechanical wear and recognizing sounds and smells. Outlet has scorching on it? Doesn't retain normal plugs? Makes Snap Crackle and Pop noises despite the outlet not eating a bowl of Kellogg's Rice Crispies breakfast cereal? Smells acrid? That's great information.

You could probably crack it open and solder leads onto the switch contacts. From there you can use whatever you want. You should meter it out though because that's only OK if it's on the low voltage / DC side of the equation. If it's somehow on the mains side then that's a non-starter. Coolguye posted:
