Yes, I leave my PW's set at 100% and I observe the same behavior with mine.

yeah, it's a real problem here for me. i remember asking the Tesla sales guy about snow on the panels back in 2018 when I first got solar. He said "it melts right off!"..... Well, No, it doesn't melt right off if it stays below 20f for a week. I won't see any solar production for at least...

I have the same situation/set-up. I have a sub panel with a set of critical circuits that I can isolate and run off my 5kw Yamaha gas generator in a scenario in which my PW's are depleted or malfunction. In 4 years with Solar/PW I have not had to use this contingency, knock on wood. I...

quick update.... we had a grid outage last night and I woke up to PW's at 90% capacity. I switched to grid charging and the PW's started charging with 3.4kw (total) from the grid. As capacity neared 100% I observed that the draw rate from the grid tapered down gradually from 3.4kw to 2.3kw...

thank you @jjrandorin i expected the charge rate would be about twice that, I appreciate you sharing your insight and experience

as stated I have two PW's...... I love the "charge from grid" option and it was one of my original enhancement requests when i got my system installed in 2018.... very happy to finally have this capability. Right now I have a foot of snow on my panels and no solar production. PW's down to 95%...

I have two PW's stacked on my basement floor. Basement is part of a two car garage. I have floor drains like you. I had both my sumps fail last year during a major rain/flood event and things got a little dicey. Floor drains were partially clogged and got overwhelmed. My wife and I spent 8...

Yes, thank you. I used Tesla support via chat on the mobile app (pleasantly surprised with the experience).... they walked me through exactly what you just described. ... turn inverter off. turn pv breaker off, wait 2 minutes, turn pv breaker on, turn inverter on..... that did the trick...

as of this morning i have had zero solar production. mobile app shows zero, connection via TEG shows zero, and display on the inverter shows zero. I checked all the breakers, everything looks good. Powerwalls are on, solid green light, show 99% capacity. I've got a big on/off dial/switch...

My gateway has no cellular connection due to weak/non-existent signal. After my install I put up a huge stink and tried to get them to switch it to Verizon or install a booster with no luck. If my ISP goes down I have to connect directly to the TEG wifi network to have any visibility into...

this thread has me confused now..... What is the best routine for extending the performance and lifespan of the PW's? I keep mine set at 100% and only draw them down during grid outages. Is it healthier for them to be cycled more regularly? Or should I lower the reserve to something less...

i have a 6.6kw PV and two PW's....when the system was installed in 2018 they put what they told me was a "soft start" on my central AC to lower start-up amperage. I'm now getting my older central AC replaced with a new Lennox Elite system.... it's a single unit, 5 ton, 17 seer. The AC...

quick update, I completely disconnected that Solar CIty black box over a month ago and there has been no loss of functionality/visiblity in my system and I have received absolutely no alerts from Tesla. at this point i'm 99.9% certain it was not needed for anything.

this behavior has changed with a recent update. i used to see 100% in Storm Watch. Only within the last few months have I observed a 98% cap. I'm tempted to toggle to grid charging to see they come up to 100%. my panels are buried under a foot of snow right now and i'm flabbergasted we...

we got about 14" and have a few hours of light snow left. panels are buried. hopefully it will slide off this afternoon. storm watch still active here. PW's at 98%. I can't believe we haven't lost grid power yet. fun fun.... headed out to plow now.

through the mobile app... Settings/Powerwall/AdvancedOptions/GridCharging.... i have this toggle and have already used it a couple of times to bring my PW's up to 100% when i've had extended periods of zero solar production.

THANK YOU!!!.... what is the purpose of the white plug with the green lights? I took a picture of the one that was connected to my cable router via ethernet in my living room. I have another in my basement underneath the living room that is plugged into an outlet with an ethernet cable running...

I just cancelled my cable ISP and switched to Starlink and now i'm scratching my head..... I had a Tesla/Solar City solar and Powerwalls installation in late 2018 and i've forgotten how this all works now. If you take a look at the pictures I had both the little black SolarCity box AND the...

have had snow on my PV for the last 3 days..... zero solar production. PW's were down to 90% with vampire drain today and we have another snow storm in forecast for tomorrow (e.g. likely grid outage). I just toggled Grid Charging to On on the app and the PW's immediately began pulling from the...

Lawyer up.

i'm just north of you in Orange County NY. I had 20 x 330 panels and 2 PW's installed in late 2018. Your system is exactly 2x the size of mine but your productions #'s are more like 2.25x that of mine. I'm curious as to what direction(s) your panels are facing? Mine are on a single...

I had Tesla install a 6.6kw array and two PW's and they were done in about 5 hours. They came in here with a big crew...maybe a dozen total. I was very impressed.

One more thought... I would NOT want to be standing in waist deep water next to two submerged live Powerwalls that are feeding the house.

completely submerged for hours???.... i'm not buying that.

Looks like it's going to be pretty bad. If you've decided to dig in and ride it out please keep us posted. Be safe and take care.

I just went back and looked at my contract from Summer 2018..... my cost for TWO (2) PW's, gateway, permits, and installation was $14,458.75. My 6.6kw PV, part of the same contract, was $25,350 all in. Seemed insanely expensive/over-priced at the time. I guess not. Glad we didn't wait.

Under no circumstances would I put the batteries in a direct sunny location in SoCal. I would do everything possible to get them inside even if it requires a costly reconfiguration.

Nevermind!.... solar just came back online as soon as PW's dropped to 94%.

Grid has been down here for about 30 minutes and counting. Powerwalls were at 100% when grid went down. They are now down to 95% and i'm still not getting any solar production on a bright sunny day here. If I recall correctly, solar used to come back online for me when PW's dropped to...

Very nice. Congrats. My advice is to put out a nice spread for the install crew.... donuts and coffee for breakfast, sandwiches or pizza for lunch, and a stocked cooler of cold beverages all day. Also get the personal cell phone # of the project lead and/or master electrician.

i do NOT have the request Request Service button showing up in my app (4.10.0) and my PV/PW's were installed by Tesla in late 2018.

in my experience the Tesla support reps have terrible communication skills and are poor listeners. i would bet that the support rep was telling you "peak" output would improve after PTO because they were confusing the meaning of "peak" with the meaning of "total"

I think you might be misunderstanding what they are saying. I'm assuming that if you do not have PTO you are not feeding to the grid. If that is the case, keep in mind the energy you are generating from solar needs somewhere to go. If your batteries are fully charged and your solar is...

@uscpsycho It has to do with the ambient temperature. The panels lose efficiency at higher temps. I have a 6.6kw array and a 7.6kw inverter. In full sun with low 70's outdoor temp I've seen my production as high as 7.2kw. On very hot summer days in full sun I will only typically see...

@uscpsycho you will never see peak production on a hot 100 degree day. my system will only reach peak if it is less than 75f outside. another variable I didn't see you mention is your inverter's rating which could be a limiting factor

I'm looking at electric options for augmenting my oil furnace as we speak. I'm leaning towards high-quality wall-mounted 120v units from Steibel to put one in the master bedroom, one in the home office, and two in open great room / kitchen area. We got crushed with heating oil fees this past...

100%.... make them put them in your garage. They are weather resistant, not weather proof.

Loss of communications can be as traumatic as loss of power. I live in a rural area with extremely poor cell phone service, frequent grid outages, and unreliable cable ISP strung above ground on utility poles. Solar and PW took care of the power problem for me. I'm now on Day 3 of having...

this pricing reflects a 30-35% increase over what I paid Tesla for a turnkey 6.6kw/2 PW system in late 2018

i was in the same boat in late 2018.... initial design had panels on both east and south facing roof sections. I changed it to south section only and they pretty much did it on the fly with no delays. i guess things have changed. good luck.

Grid charging! I am so excited. This will come in handy in and around weather events. Super pleased to see this thread... THANK YOU!

when I got my system in 2018 I was told by the sales rep that the volume/frequency of battery draw down degrades performance over time and also shortens the overall lifespan. I'm pretty sure that there was some language in my original contract on this topic as it related to warranty. I will...

will that allow solar to feed the house in a grid outage?

@nwdiver thank you. he is looking to replace his existing inverter with something that will feed his panel during times of solar production. not considering storage at this time (despite my strong recommendation) because of finances

I'm trying to get an answer for a friend with an existing grid-tied solar array. He is asking if there is any inverter available that can direct power to the house without battery storage in grid-down situation (obviously only at times when there is solar production). It looks like the Sol...

@ucmndd While I agree with your Tesla comments, I respectfully disagree with your comments on GM. These EV Hummers are currently selling at 2-3x MSRP with dealer markup or through flippers on the secondary market..... So GM is actually charging a far cry from what the market will currently...

yes, thanks. obvious typo. i can keep average draw to 450-500 WATTS

@Ampster I understand the distinction, but the $100k cost of the EV includes wheels, tires, suspension, frame, body, glass, electronics, infotainment, interior, etc. etc. etc.

i'm probably late to the game here, but I just saw that the new Hummer EV has a 200kwh battery pack and an approx $100k msrp. what percentage of that $100k represents the cost of the battery to GM? 200kwh capacity is the equal of 15 PW's. It seem incongruous to me. If GM can engineer...

To the original poster..... it will be a learning experience for you, it certainly was for me. If you are not beholden to AC, electric heat, electric dryer, electric range, and/or electric hot water in a grid outage, you should be able to keep your household consumption down around 10-12kwh...
