VPP question.

I normally set by reserve to 70% due to net metering and to make sure I have enough for outages. My VPP setting is 20% reserve for events. I noticed this year that at the end of the event and my powerwalls are at the 20% mark they will immediately start charging back up to 70% from the grid. Did something change? I don’t recall doing this in the past.

Tesla charge on solar issue

Anyone know why my Tesla solar page shows 6kwh went to the car but Tesla car shows only 3kwh charged? I understand car consumes some power while charging, but this is a big difference. The car is in garage with temp around 74F.

Broken Solar City tile at Bolting Point

What is the chance Tesla repairs this under warranty as I have a 20 year pre-paid solar lease thru Solar City (Tesla)?

The damage roof tile is at the bolting point. Another one under another panel and it’s slipping. This system is 8 yrs old. Roofer said it was due to installer at the bolting point.

App accuracy

My app consistently shows a correlation of production and usage so if it gets brighter and my production goes up, it will simultaneously say my usage has gone up. That cannot possibly be accurate which then leads me to question the overall accuracy of the information that’s being provided to begin with.
Has anyone else experienced this?

Is it worth going from 2 PowerWalls to 3 for ~$1k?

I have 8.46kw of solar. 2 EVs. Using approximately 18,000kwh per year. I feel like I only need 1 Powerwall + 1 expansion, but the cost to add another expansion battery is very negligible.

Is there any downside to getting a 3rd one?

EDIT: Miscommunication with the installer. The difference is actually $2.8k to go from 1 Powerwall + 1 expansion battery to 1 Powerwall + 2 expansion batteries. However, I’d be getting an additional $440/yr through VPP. Still worth it right?

National Grid MA VPP

Forgive me for sounding like a Noob but this is my first full
Summer with export and VPP. National Grid pays $275,, and Tesla cuts $220 per KW here. I set my PW3 + Expansion to drain to 0% during these and since it’s a bit vague on what you get paid out till the end of the season, I figured I’d ask here.

Since that is draining the full PWs, do I get paid on the amount exported or the full amount drained? since the house has to be powered by the battery during these events. If it’s the full battery $220 x 27 is $5,720 which seems absurdly high for something as simple as letting them use the battery, but is my math correct here?

Battery

Hi I just installed a 6.6kw PV and 6kw hybrid 3 phase inverter along with a Tesla wall charger. I am in perth. To be able to charge using super off peak at 8cts/kw is awesome.

Wondering if I should get a 12.8kw battery now as not sure about the ROI and the payoff period. The battery would cost $5600AUD and my last year electric bill including ev charging which I was only charging at 20cts/kw (which I used to charge at night only. But now with the wall charger, I can charger everything at the super off peak) is $2500 in total.

That said, I was quite conservative on the aircon and heater usage, turning on only after 9pm when it was off peak.

Charge On Solar Not Working

Solar & PW3 just installed. Haven’t gotten the PTO yet but the panels are producing. ‘Charge on Solar’ option isn’t appearing in the app, and I’m wondering if it’s because it looks like I have two houses instead of one location? Should I delete one of them and pair again?

Powerwall and export limits behaviour

I'm trying to work out how to get my Powerwall and separate PV system play nicely together when I have an export limit. To be clear, the Powerwall is _not_ the PV inverter in my setup - I have separate micro inverters on each panel.

I have very recently implemented a 5kW site export limit. The PV system manages this by monitoring the grid connection and adjusting generation so the export is under 5kW. This is the only way of limiting export available to me.

The problem is the Powerwall, which is also aware of the 5kW limit. At the time the screenshot was taken, it's sunny enough that the PV system could be producing 6-7+ kW if it weren't throttling itself to keep under that 5kW limit...but it's only needing to throttle itself because the PW is providing power to the house, let alone using the excess to recharge itself.

My utility rate means 'peak' is between 05:30 and 23:30, with off-peak overnight. The Powerwall is getting the tariff information directly from my supplier. It seems to be a chicken-and-egg situation where the Powerwall is discharging because the export is at the limit and it's 'cost effective', but that very same discharge is preventing me from using PV generation that's being throttled, meaning the PW keeps discharging to maintain avoidance of peak, etc etc

While I've had the setup installed and working a decent while, it's only in the last few days that the export limit has been required - and will remain required unfortunately.

What should I be doing differently here? Any and all advice welcome.

New set up added panels learning

Powerwall after solar increase

Just want to check with people this should improve!

Had solar panels and powerwall installed last week and unfortunately for the first week only 2 of our arrays were working as the roofer had forgot to connect them properly.

The powerwall was working and learning with a much smaller solar production than we are now getting.

We are now producing about triple the kWh we were for the first week. We do not have permission to export yet.

The problem is the powerwall is still charging on the cheap overnight rate more than needed as doesn't seem to be aware it will fully charge during the day and keeps pulling a small amount from the grid during the day to power the house despite the battery being full and solar being capped due to no export.

Should this improve when we get export and when the powerwall learns we're getting more solar regularly?

Is it bad for my battery to be discharged for so long?

UPDATE: Even though Tesla said only the Powerwall 2 will be replaced, I contacted support and they said both Powerwalls will be replaced, so I’m glad to hear that! So I guess my question is answered.

I have Tesla solar as well as a Powerwall 2 and Powerwall+. My Powerwall 2 was subject to the recall due to potential cell failure. Tesla discharged my entire system (Powerwall 2 and Powerwall+) until they replace my Powerwall 2 with a Powerwall 3. However, my Powerwall+ isn’t being recalled or replaced, and is just sitting empty for about 3 months until they were able to schedule the replacement. Is it bad for the Powerwall+ to be discharged and sitting empty for so long?

Tesla disqualification for panels

Can someone explain what are my options?

Thank you for your interest in Tesla Energy and for choosing us to help power your home with solar.

After a thorough review of your project details, we've determined that we cannot meet Tesla required minimum 8 panels on your roof. The designer was only able to fit 6, which means we will not be able to proceed forward with your project at this time.

As a result, we're unable to proceed with the project at this time.

Tesla solar owner

My solar panels from Tesla are less than a year old and I noticed May and June. I was loved with high electricity bills. I called Tesla and they said something is wrong with the system and it will take up to two weeks to review.. I’m under warranty, but this is ridiculous. I’m missing the summer months entirely with no banking of energy and higher electricity bills. I’m so upset. Has anyone else encountered this problem?

How do I get a hold of Tesla repair/service that isn't an AI bot?

I have an open service request. This is solar production today. I have spikes down to 0 production repeating over and over again on other days too. Today I cracked the inverter panel to see the fan not moving. I could hear the coolant flowing, but no fan movement. At around 14:30 I put an external fan on the inverter with it cracked open. It started producing at full pretty quick. Would like to get a hold of Tesla to come replace a fan instead of the inverter for the 5th time in 4 years..

DIY Solar is going to be the next big movement

I'm convinced that cheap solar is going to start being seen everywhere. On balconies (it already is in Germany!), on car roofs, on fences, draped from garages, etc. It's too smart and obvious not to be used everywhere.

I just built a site to better inform people what's possible with DIY solar. You no longer have to own your roof. Renters can do this too.

Tesla app no reporting properly

Has anyone else had the following issue? My solar app says it’s been producing for the past four years, but my electric company says that I haven’t been producing Solar for over two years. Isn’t this negligent or fraudulent on the part of the Solar company?
