    Advice on using a DC -> AC inverter to charge my tesla from an ICE 12V battery

    I live in an apartment complex with no place to plug my car and rely to periodic supercharger trips (less than ideal, I know). After coming back from vacation oversea I found that my car showed 1% charge, or 2 miles, enough to reach the supercharger 1.6 miles away (sigh of relief...). I was...

    Can Tesla inverters be sold or transferred?

    Hey everybody, I have two Tesla inverters from May 2021 before powerwall was required. I'm thinking about doing my own battery install and may want to sell my Tesla inverters and buy hybrid inverters instead and just use the current arrays. Does anyone know if it's possible to sell inverters...

    Could Tesla solar panels connections to grid and house have been mixed up?

    I had Tesla solar panels installed at my house. After city inspection Tesla technician turned the solar switch on because I had solar permit for an earlier system that is running. He said it is ok. In the tesla energy app I am noticing the numbers and graphs don’t make sense. The grid graph...

    Tesla App Energy Production: DC or AC?

    Regarding Tesla solar energy products: Is the production of power (kW) and energy (kWh) *as shown in the Tesla app* either DC (before inverter losses) or AC (after inverter losses)? For PV array performance monitoring, I would want DC. For utility bill comparison purposes, I would want AC. My...

    Tesla installed strings in parallel on 7.6 Inverter

    7.6 Tesla inverter and 24 panels All my panels - 24 are pointed south, but i have trees and shading on each side of the roof. So i asked tesla to install at least 3 strings. But they told me , since their pipe coming down is not thick enough- only for 4 cables, they have 3 strings, but 2 of...

    PTO finally approved but Tesla App not working

    So I received my PTO on Friday around noon for my Tesla Solar only system (no battery). I immediately turned the system on after receipt of PTO. A day later and my Tesla app tells me that “No products found”. I logged into the inverter to see if I could find anything wrong. I noticed a message...

    Tesla switched inverter to Delta (no optimizers) from promised solaredge (with optimizers)

    A couple weeks ago, we had install of a 11.8kw panel set with 3 powerwalls completed. While I was promised a system power optimizers for shading and a solaredge 10k inverter (both verbally and was on the planset in 11/2020), what is actually installed has no optimizers and a Delta M10-TL-US...

    Solar advice

    Thank you for these forums, I've read a lot and learned a ton. I have been considering tesla solar since getting my model 3. I have interviewed 4 other solar companies and am consistently being warned about tesla's 10-year warranty vs 25 with local companies and the lack of customer support...

    Advise for installation day?

    Tesla called to offer install on Monday. This is in PG&E territory. I would appreciate any advise for what to expect or if there are any choices I need to make. I still wonder if the inverter should be in the garage or outdoors. I see both options in my neighborhood and I wonder if those inside...

    SolarEdge Inverter Issue-DC Error

    After running my TE Solar setup for about 9 months (and the recent addition of the 3 PWs), now we are having a new DC error message pop up as below on the inverter. Tesla took the particulars and will have scheduling call back. Last time (last fall) this meant several wasted months until...

    Whining Noise - While en route to Supercharger

    Although its been about two months since the battery conditioning feature en route to superchargers was released, I just noticed for the first time (possibly because I didn't have music playing) that there is a very distinctive high frequency whining noise coming from either the inverter or the...

    Looking For Sport Rear Motor & Inverter Subassemblies

    I can get good drive unit assemblies in lots of places, and in fact, they've fallen precipitously in price the past year or so. But, I'd prefer to give a good home to a MS or MX PERFORMANCE ("Sport") rear drive unit, or the subassemblies, where the diff or gearcase got trashed in a side hit...

    Tesla car battery to power my house

    No answers, only question! If I buy an inverter, can I use the power in my Model S to power my house at night? If yes...how do you get the power from car through inverter, to house use? Seems like a good wheeze!

    Powerwall 2 with inverter vs external inverter

    I've done quite a bit of research on this, but I've had a hard time finding reliable information. My wife and I are interested in adding solar to our home, but she is (understandably) concerned about the number of boxes that will be on our walls. I see that the Powerwall 2 comes in a model that...

    Warm-up before aggressive driving?

    ICE or not, I still feel reluctant to be aggressive with the car right after pulling it out of the garage. I know there's no motor oil to warm up or circulate. No radiator coolant to stabilize warming engine parts... But there are still lubricants in the motors, drive train, and suspension and...
