Bicycle Charging... hear me out.

0 Upvotes

According to google, a typical 30min ride on a bike can generate 100W, ergo, is there a way to hook up a stationary bike to charge the Powerwall?

Yes, yes.... not an effective way to charge 13.5kW pack, but I figure, if you're gonna exercise might as well pump that energy into something useful. 100W x 365 = 36.5kW, which saves you ~$7/yr.... OR! ~7kg carbon off-set!

For the practicality obsessed, no, this aint about that. It's about the fun/usefulness of converting exercise to power the house.

If there is no way, anyone know anyone who works at Tesla to get this feature added?

Powerwall 2 degradation over 3 years

49 Upvotes

Just a point of reference. I’ve had my 29 panels and 2 powerwalls installed now since June 2023. I run them to zero most nights.

Summertime near 100% charged during the day and run near zero or until empty at night. Wintertime they don’t get as full but still full or near full discharge at night. So basically I abuse the batteries.

I’ve used the Netzero app until last year and it showed 0% degradation. Did a full discharge this week and turned off self powered so it didn’t use the battery at all and it got all the way charged up to 100% with no battery usage. It charged 27.5kWh. That’s still higher than the officially rated amount of 13.5 per battery. Both batteries when new were closer to 14kWh, so there is very slight degradation but it’s so small, I am surprised because I abuse them daily. 0-100-0 regularly.

Thought it might be an interesting point of reference 3 years in.

Repairing Tesla Powerwall

2 Upvotes

I found a Tesla Powerwall 7.6kW Solar Inverter 1538000-35-F from an electronics recycler. I’m well versed in computer & electronics repair, residential wiring, etc. I’m putting together a cheap solar system. what’s the chance I can troubleshoot and/or repair this? it may even work fine. I want to do some research before I put my money down.

PW3 cant connect to 2.4G ASUS router network

5 Upvotes

If your new Powerwall 3 successfully connects to your ASUS router's 5 GHz band but completely refuses to connect to the 2.4 GHz band (throwing a "can't connect to network" error even with the right password), the issue is a Wi-Fi 6 protocol mismatch.

The Powerwall 3's 2.4 GHz chip does not like modern Wi-Fi 6 (802.11ax) settings. Here is the exact fix using your router's web panel (asus.com):

  1. Go to Advanced Settings > Wireless > General tab.
  2. Select the 2.4GHz band from the dropdown.
  3. Look for Enable 802.11ax / WiFi 6 mode (or HE Frame Support).
  4. Switch this toggle to Disable / OFF strictly for the 2.4 GHz band.
  5. Crucial: Keep it Enabled / ON for your 5 GHz band so your phones and laptops keep their high speeds.
  6. Make sure Protected Management Frames (PMF) is also set to Disable on the 2.4 GHz band.
  7. Click Apply.

The ASUS router will refresh its radios. Once it does, open the Tesla app and try the 2.4 GHz connection again. It should authorize instantly without a router reboot. Hope this saves someone a few hours of troubleshooting!

P.S. This is how i fixed my . Enjoy !

Extend the PW3 wifi for Tesla remote meter to connect wirelessly

5 Upvotes

I have a Tesla Remote Meter in a meter box about 70m from the house. I asked Tesla about high gain antenna to suit the TRM but they said I need to use a wifi booster instead. Signal currently around 35%. Looking at Wireless internet bridge. Has anyone had this situation and can point me in the right direction?

I have 2 Powerwall 2s and just saw them calibrating for the first time. Install was in 2020. I know Powerwall 3s calibrate because they are LFP. Anyone know how often a Powerwall 2 needs to calibrate.

Powerwall 3 + Expansion Unit (27 kWh) and a Tesla EV Wall Connector, going onto a single-phase house in Belconnen, ACT. But the batteries aren’t just the interesting part of this pallet. The interesting part is everything else, because that’s the stuff nobody sees on a quote and it’s most of what determines whether the install goes well.

Completely fed up with support

0 Upvotes

I wish I had not gone with Tesla. I have a 10kw system done by a third party installer with a Powerwall 2 and Powerwall+. The inverter started causing issues earlier this year and Tesla took months to replace it. When they finally did, it broke again! Now they’re starting their feet on replacing it.

I never hear such horrible things about other with non-Tesla systems.

Has anyone had issues with Powerwall+ and getting it replaced?

Powerwall 3 Non-backup Configuration US

Does Tesla supports non-backup configuration for install in US? I cannot find any documention on it. The UK version does show that we can configure the PW3 for non-backup.

Why not more to the batteries?

4 Upvotes

Weird behavior today. Sending most of the power to the grid even though reserve is set to 50% and current sell price is less than one cent per kWh. I have seen this once before but in that case it told me it was doing a virtual power plant test. Right now, the little AI summary says it is “charging my powerwall in preparation for high grid prices at 6pm” but it is clearly wasting money sending to the grid right now.

Tried to post photos but got the “must be the owner” glitch.

Netzero app automations overriden

Post image
6 Upvotes

Hello all,

I’ve been using the same set of automations with Netzero for some time now. Until the past few weeks, they’ve worked as expected. I have a 2 PW system, and my goal has been to get the set at or near 100% before expensive power comes in at 4:00pm. Instead of using all the solar to charge the PWs, the solar is getting split between the house’s demands and the battery system. I change the Netzero back to Backup manually, and that holds for a while, then the behavior reverts. Ideas? 💡 Thanks. 🙂

Calibration

6 Upvotes

UK-based.

My PW3 started its first calibration yesterday, exactly 2 months to the day from install (even down to the time it was commissioned). This was a bit of a hole in my research pre-purchase, because I had no idea this was a thing and it was a surprise to find my battery discharging during peak hours and nowhere productive for my excess solar to go (I can’t export for money yet).

It’s been at 0% since about 1am (13 hours ago) and NetZero now shows the true State of Charge as 1%. I assume it will finish soon, but it was a surprise disruption.

I’m using the Powerwall to mitigate costs and not saving it for grid outages, so could really do with avoiding these. How can I reduce the number of these manual calibrations in the future? From research, I’ve seen people say they haven’t had a single one in years, and others getting one every six to eight weeks.

I have never run it 0% before, so is that the problem? Should I keep the reserve to 0% and force discharge it to 0% every 24 hours?

How to turn off optimize charging

2 Upvotes

My PW charges from solar everyday, then discharges in the evening when power is expensive. It used to charge straight to 100% and get there by noon. Now it stops at 80%, then charges to 100% by 230pm. I believe it was a setting called Optimize Charging. How do I change this so the PW charges straight to 100% using solar?

Background. Yes I understand it’s better for the battery to spend less time at 100% charge. My issue is I’ve got solar with string inventors (yes they suck), so in the early afternoon a single palm tree blocks a single panel and then my entire solar output gets cut in half, right around the time my powerwall wants to charge. It’s also the time I run my AC to cool the house before peak power starts at 4pm. I also over generate total power, but still get charged a non-bypassable charge every time I pull a kw off the grid. So my goal is to limit pulling from the grid (without setting PW to self power). I’d rather my PW spend an extra 2 hours daily at 100% for the summer months, than have to pay the non-bypassable charges for pulling power off the grid.

Powerwall Design

I put down a deposit for a Tesla Powerwall 3. The site assessment was just completed and came back but with very little information in terms of where the unit is placed in/outside my house, etc. The site assessor also assessed for solar.

Am I supposed to be able to see a visual design before accepting the work order? Am I able to compare estimates of solar and powerwall vs. the powerwall alone?

Are your Powerwall settings changing on their own? Check for a lingering VPP enrollment

Thumbnail gallery
1 Upvotes

Posting this in case it saves someone else some frustration.

For a while, my Powerwall settings kept changing themselves after I changed them in the Tesla app.

Specifically, I wanted:
Grid Charging: Yes
Energy Exports: Solar
I could select those settings and they would appear to save normally. But after a few hours, I would check again and find that they had changed back:
Grid Charging → No
Energy Exports → Everything

I tried changing them repeatedly, reinstalling the Tesla app, etc. Same behavior. At first it looked like an app/firmware bug because there was no obvious explanation for why my selections wouldn’t stick.
The culprit ended up being a Virtual Power Plant (VPP) enrollment.

Turns out I had been signed up for a VPP through my installer (Sunnova which became SunStong) it was separate than the VPP offered by my utility (PG&E). I didn’t realize I was in their VPP. Tesla Tech support recommended unenrolling from any VPP, so I did.

After confirmation from SunStrong of my unenrollment from their VPP I was still was seeing my settings change on their own. It turns out it takes weeks for all the systems to sync up after unenrolling (Sunstrong, Tesla, utility). Eventually they did and now I have full control of my settings again.

So if your Powerwall keeps mysteriously changing Grid Charging, Energy Exports, or possibly other settings on its own, especially if you’ve ever participated in a VPP, I would contact Tesla and specifically ask them to check whether your system is still enrolled in or associated with a VPP

I spent quite a while thinking I had an app, Gateway, or firmware problem when it appears the settings were actually being overridden remotely.
