    Why did Tesla remove option to disable regenerative braking?

    I'm surprised that no one has pointed out the missing feature in Tesla's, hybrid braking with the brake pedal. I'd like configurable one pedal braking + hybrid braking with the brake pedal. Tesla may be the only one lacking this.

    V2G with PG&E, Tesla, and Ossiaco?

    Mine is an american standard, ducted, traditional forced air. 1 compressor, 1 indoor coil, 3 ton. I have heat strips for backup, but they don't seem to be needed or come on until less than 0F. The heat pump is supposed to work down to -10F, but I'm not so sure about that.

    Moving to new house.. solar system sizing

    I meant the design of the actual roof, to get more south facing area.

    Moving to new house.. solar system sizing

    Can you put more panels on the south facing roof? Unless you're offgrid and need the morning charge as ohmman mentioned, I think the return on investment for the east facing panels will be pretty small. East & West facing will have the same solar gain but if you're on TOU net metering that...

    V2G with PG&E, Tesla, and Ossiaco?

    10kw would be enough to run my heat pump and blower, as well as the refer & freezer. Connecting the 220V heat pump would obviously be more complicated than an extension cord. A 75 kWh EV battery would last a couple of days in very cold weather.

    V2G with PG&E, Tesla, and Ossiaco?

    10 kW would be plenty for emergency backup You could, it would be nice, but not required. The primary goal is to keep the food cold or frozen. My thought is that we connect to the high voltage battery. The DC to AC inverter would be on the wall in the garage close to the car. This is a...

    Moving to new house.. solar system sizing

    Yep, you're probly right about that. It also depends on the net metering details you have, and as ohmman pointed out the TOU details can change. Do you get paid full retail TOU rates for your surplus?

    Moving to new house.. solar system sizing

    Not super insulated, just IECC 2013 Code (I think), which is R60 attic, and an extra 1" outside the studs. No vaulted ceilings, 1 story. I do get heating help from passive solar. Avg production for the last year was 650 kWh / mo. Dec was 440, Jan was 520. Yesterday we got snow & I went...

    Moving to new house.. solar system sizing

    OK, maybe not a blanket statement, but an easily misinterpreted generalization. I have all electric, including heat, 2300 sq ft, EV in the budget, and 4.4 kw is enough. I am not in CA, I have more solar gain, but a much higher heat load.

    V2G with PG&E, Tesla, and Ossiaco?

    +1 . I wouldn't want to use my expensive EV battery for V2G, but V2H for backup situations makes so much sense. We just need a connection to the high voltage battery and everything else is external .

    Moving to new house.. solar system sizing

    If you're producing more than your consuming, and and not getting paid a good rate for it, then it's oversized and isn't a good financial choice. The OP needs to do an estimate of current consumption, in kWh not $, add something for near term EV changes, and an estimate of solar production from...

    Moving to new house.. solar system sizing

    A blanket statement that 4 kw is extremely small, is just false. I have 4.4 KW and have an annual surplus now which is enough for about 10000 mi/year for an EV. There is an online tool called PVWatts which I don't think anyone has mentioned. You enter the data for your system including...

    Xcel Discounted Charging Program Report

    According to the rate book, residential rate is 0.103, off peak RE-TOU is .093 . 10% cheaper, but not a huge cut. The spread widens in the summer though. I think it's about 50% more expensive on the regular rate. When I made the switch last year I compared the plans for what it would cost...

    Interested in Utility Scale Renewables ? Delve into ERCOT

    Why are these the only choices? Most of us in the US are on a fixed rate plan and do not have rolling blackouts.

    Texas Superchargers Out of Service?

    I see several posters make assumptions that the car app will show if a super charger is down, did anyone actually verify that it worked? I'm sure there were a few superchargers down in the crisis

    Yes, perhaps the weather was accurately predicted, but No, they did not plan for it.

    Cold weather heat pump comparison

    Is there any data out there comparing the earlier M3, no heat pump, with the new M3 with heat pump for efficiency and range in cold weather?

    Steep Driveway - Help Please

    It looks like your bumps are too close to the corner of the concrete. Try putting them a wheelbase apart and centered on the hump. You may need more of them. The solution may be expensive, shave down the driveway, or buy a Y. Is that a standard 3 or performance?

    It looks like Texas free market, libertarian bent is coming back to bite them. I don't understand why Musk is putting a plant there. "Ercot’s authority is somewhat limited. In 2011, the last time freezing weather caused rolling outages, it released best practices for power generators to...

    Texas grid crisis

    What's going on in TX, etc? It sounds like demand is hitting record levels, do they use a lot of electric heat there? They're losing production too. Blackouts Hit 13 States Beyond Texas in Deepening Power Crisis "Power plants with a combined capacity of more than 34 gigawatts were forced...

    Poll: Tesla RV anyone?

    I'd be interested in an electric camper van, sprinter/promaster/transit sized. An RV build on the tesla semi doesn't make sense for me. Maybe once they get the cybertruck rolled out they can do a cybervan, but since the body of the cybertruck is integral to the design, it would have to be...
