    Connecting to Powerwall3 when Internet is down

    Another option is to use a secondary internet connection. I am using a T-Mobile home internet device as a secondary WAN backup on my UI UDM-SE router. It costs me $25/month, and is connected as long as T-Mobile is active. While mine is always active 'unlimited', they did recently start...

    Power Wall - No Solar Option

    Without solar, you'd need something like this, and a bunch of red bulls.

    Power Wall - No Solar Option

    To fully charge an EV, you'll need to factor in a car battery size versus the Powerwall. A typical Tesla car battery is 55kWh -> 100kWh. A Powerwall is rated at 13.5kWh. In order to charge an S3 base model (55kWh) by 50%, you'd need at least two Powerwalls. Four for a long range vehicle. In...

    Powerwall 3 calibration in process, what is this?

    Yes, you save a lot of money going with Tesla, but you have to be your own project manager to ensure things keep moving along :)

    Slate style Tesla Roof?

    Solar roof was an option when I priced my install out in 2022. It was 100% more expensive than panels. I could not justify the added cost. There is the added benefit of a lifetime roof, but I could install two metal lifetime roofs + panels for the cost of the solar roof.

    Tesla Solar Roof cancelled during design phase with no explanation

    The same happened to my area, after my install was complete. Mostly because Tesla had such a hard time with my utility, and they (Tesla) spent six months negotiating what equipment they could use (I ended up with the prior gen inverters versus PW+ inverters). Tesla's solar site now lists a...

    24.4.0 Gateway crashes

    Any way you can hard wire an ethernet connection to your gateway? That solved pretty much all of my sporadic network connectivity issues.

    Constant Grid Power Usage Despite plenty of Solar and/or Powerwall Power to cover home load

    What I got from this: when I contact support, I should put in my ticket 'please assign to Andrea'. :)

    Contact for following up on Tesla Order?

    Easiest way is to use tesla.com/solar and input your address. It will tell you if there are Tesla installers, contract installers or no installers. That's for purchasing through Tesla directly though, it will not show local installers who have chosen not to partner with Tesla install but sell...

    This is why I went solar...

    Oh yes, switched out all my bulbs to LED long before going solar. I was in electricity cost cutting mode prior to solar. I'd even charge my kids a quarter whenever they left the lights on in their rooms. I'd tell them 'if you are leaving them on, you are going to help me pay the bill'. In...

    This is why I went solar...

    My cars are all paid off, so that makes justification for an EV that much more difficult. Even the cheapest EV is still in the $30k range. The monthly payment would nullify any additional savings.

    This is why I went solar...

    I wish my usage had gone down 25%! Probably closer to the opposite. My wife now thinks we have free energy (which was mostly my fault when we discussed and made the decision to purchase solar), so the thermostat temp has gone down several degrees. My kids that are still living at home are all...

    New Powerwall Install not charging

    Something is definitely wrong, as it is extremely unlikely that your house has zero usage.

    This is why I went solar...

    Before solar, I'd typically use about 1,800kWh from my utility per month. Now, almost two years with solar, the total grid power I have imported is 1,332. While I'd love to see more negative bills, having an electricity bill of $0.50 is, well, not priceless, but almost. I think my utility...

    Powerwall 2 Off grid clarification

    I imagine that even if you don't get credit for sending power back to the grid, it may be better to send it anyways instead of sending freq changes and shutting down the inverters several times during the day. Maybe I'm just timid about forcing something to shut down. Then there's the case...

    Possible Hardware Issue?

    I'm thinking 'Inverter/battery info (/system_status)' would provide error codes.

    System down - production compensation

    Same boat. I at least check daily, always curious how much production the day had and look for anomalies.

    Possible Hardware Issue?

    If you use Netzero or Powerwall Dashboard, you might see errors logged to identify potential issues. I'm assuming that since was installed 1.5 years ago, this is all Tesla gateways and inverters. For instance, Powerwall Dashboard gives me a list of what messages have been logged in the last...

    Tesla Solar Roof cancelled during design phase with no explanation

    There have been several solar roof cancellations, which could be a number of reasons: no installer for your area, too much re-work for the roof structure/weight distribution. How long was your order in process?

    Tesla Announces Powerwall 3 "DC Expansion"

    I replaced my water heater with a GE Geospring hybrid about 8 years ago. I also bought the Home Depot 10 year warranty for it. About 2 years in, it didn't seem to be heating the water appropriately, so I contact HD for help. They couldn't find anyone to service it, so they sent me a check for...

    System down - production compensation

    With the Tesla inverters and Gateway devices, Tesla has been known to proactively monitor and contact owners of impending issues. Not often, but they do reach out, as ascertained from many other posts here.

    Tesla power wall in Tesla app. What am I really seeing?

    Sense Solar CTs have always been off. The only way I could get them to work was reversing the polarity on one of the Sense CTs, and sense support washed their hands of supporting me when they knew I had batteries. I don't really pay attention to them TBH. I use sense for understanding my...

    Tesla power wall in Tesla app. What am I really seeing?

    Here's May 2nd @ 11:45am. You can see the gradual increase in usage, as my solar ramps up. This is my usage, I picked a spot prior to my AC or pool heat pump kicking in. Here's my solar production at that time: Comparing what sense saw for panel usage at about that time: 1411w at the...

    Annual (temporary) goodbye to grid power?

    I might be nearing the end of my good spring run. I'm down to 27% battery and it's going to be a stormy day, IRL and in my span of grid freedom. And, now stormwatch has kicked in....

    Tesla power wall in Tesla app. What am I really seeing?

    On my install, l see the 10% loss in the house usage versus inverter cost. My house will show about 1.5kW higher than my Sense or Emporia says my house is using when I'm hitting 15kW solar. That seems to be because Tesla is accounting for the inverter wattage that is needed for the conversion...

    Constant Grid Power Usage Despite plenty of Solar and/or Powerwall Power to cover home load

    Just FYI, you can request Tesla to adjust the inverter turn-off frequency. By default, my system changed from 60 to 65Hz when off-grid or grid outage situation, when the batteries were full and solar was more than the house was using. My uninterruptible power supplies, which I have my...

    Does a battery ever have a positive ROI with net metering

    My ROI on batteries is about 9.5 years at current electric rates (after federal tax incentives, and after solar ROI is reached @ 5 years 7 months). My utility has raised rates twice since I installed, so I can only assume that timeframe will reduce over time. That's just about at warranty...

    Annual (temporary) goodbye to grid power?

    I drew power from the grid on April 4th, haven't touched it since. Well, other than grid sync. The graph below shows my set of powerwalls charge rate (reserve set to 20%) - April 1st to today. Here's my import vs export graph. This is a cumulative graph - blue line is export and purple...

    Three Consecutive Perfect Sunny Days - Variation in Output

    I have a 20.4kW Tesla system, 51 T400 panels with two 7.6kW inverters. My max daily production (to date) was 137kWh.

    Three Consecutive Perfect Sunny Days - Variation in Output

    Adding more data. Not trying to decipher specific reasons, just think it is an interesting exercise in looking at variables. Wind speed was pretty close on each day. Wind direction was slightly different... I bet that is a key factor.

    Three Consecutive Perfect Sunny Days - Variation in Output

    Yes, there were some clouds at the tail end of April 14th, around 6:45pm. Around then I am typically down to 2.1kW production. It probably impacted slightly. I actually seem to have had more high clouds on the highest production day, April 13th, throughout most of the afternoon.

    Three Consecutive Perfect Sunny Days - Variation in Output

    This is more of a dissertation than a question. I had three perfect, consecutive sunny days, April 13th through April 15th. I know temperature affects solar output, but what about humidity and barometric pressure? The production variations are not very big, less than 5%, but I expected them...

    Overproduction error on Tesla inverter

    Yeah, don't think an inverter would run consistently at 165% production. The 7.6kW inverters barely do 125%. Plus, unless you have giant magnifying lenses pointed at your panels, not likely that 4.8kW of panels will produce 6.1kW.

    Powerwall 3 set to 45% backup reserve, at 43% now

    From my experience, this is normal. My reserve is set at 20%, and on those times I reach that threshold (sometime in the middle of the night usually), by morning the PWs are down to 18 or 17%.

    Constant Grid Power Usage Despite plenty of Solar and/or Powerwall Power to cover home load

    Amazing accomplishment! Next up? Cancelling Comcast/Xfinity? That'd put you 2/0 into superhero status! That is a long time to go with issues, I can understand the frustration. Glad you got it sorted, and thank you for sharing your experience and resolution. It will definitely help someone...

    Tesla Says I Can Only Get *ONE* Powerwall bc of my Utility's Rules

    There was several, but one was around how the inverters are designed to run consistently at 125% output. They also said that running two strings in parallel would serve better across the south facing roof. I thought I knew enough, but the wonderful people on this forum have helped me learn so...

    Powerwall 2 Questions

    There is not any feedback for the PWs provided from the units themselves. The communication wires to the gateway relate all the PW status. I suppose it is possible to get the green glow if you hook it up and power it on, but I've never done that so can't say for sure.

    Tesla Says I Can Only Get *ONE* Powerwall bc of my Utility's Rules

    There is the possibility that the installers will alter the plans, not to fit your best energy strategy, but to make for the simplest install. I had shared shading timelapse with my designer who altered strings based on the information I provided. The installers looked at the plans and made...
