The point of having battery backup isn’t to run everything at maximum capacity, it’s to keep the essentials running such as fridge and freezers. Not to charge all your electric cars and have the aircon and every light in the house on.

[@knightwolf3511]

Yes but if everything is running when the power goes it will trip. If you know a cut is coming then you can reduce your usage before hand but that doesn't happen.

[@jeffklaubo3168]

@@pignonMZ6 what I'm saying is money is what makes the world go round. Currently with energy being distributed the way it is, no competition, there is no incentive to reduce consumption. There is more incentive to increase consumption than reduce it. Example, There are 500 companies contributing power to the Eastern grid. 500. All of them share and operate on the same grid. You know how many options I have for power companies? 1. I have 1 option. There's no other choice, I have to put up with their bs, incompetence, and lack of caring. They have no incentive to do more or be better because I and the other people here have no choice except living a life without power (good luck), but then the government also guarantees them the right to make a profit. They operate on the worst parts of capitalism and socialism. In reality laws of supply and demand would dictate as people use less energy it would become cheaper as there would be lower demand, when in Stark contrast to that as people use less, they raise their prices. You want people to use less, allow the market to work.

[@goaway3717]

Thanks for the run down on how you use your setup. Personally all I need to cover is keeping a mini fridge operational during the occasional blackout (to keep temperature sensitive medication from spoiling) and cannot put any solar up where I live so my battery backup solution is considerably cheaper than yours but still grid reliant. I figure for the vast majority of my needs I can get away with around $1500 in battery generator cost which will give me enough to cover all but a multi day blackout which has only occurred twice in 20 years where I live. Lucky you to live where the power company doesn't gouge you on power prices - mine plays the summer multi tier game to squeeze more money out of us in "summer" and they're getting ready to play the smart meter shuffle and bend us over for more money at different times of the day or whenever the whim hits them that they need to compensate for increased demand all year round.

[@rolf-smit]

I finally understand why the powergrid in the USA is struggling 😂. This dude uses more power on his own than my whole street (in the EU) does, taking into account that I have 12 solar panels and still power left to deliver back to the grid (and yes we do have electric cars as well, guess our houses are just a tiny bit smaller 😂😅)

[@albanbirch]

Indeed. I use around 256kWh a month, including charging one EV and excluding my PV. I actually produce almost twice as much electricity as I use. Batteries won’t make sense in my case either, because I get paid more per kWh for the electricity I put in the grid than the electricity I use, plus the PV is on a completely separate meter.

If you like to learn Dan, be careful at 9:21 you switched kW and kWh. kW is a unit of power, so your house consumption is in kW (you can see that in your app) kWh is a unit of stored energy, so your Powerwalls should be rated for this. So one of you powerwall is 13.5kWh and is capable of an output of 5kW, that gives us, without loss 2.7 hours of usage out of them. A little physic course for you ;)

I appreciate your honesty and showing the actual usage of the cars and house. Seeing what each cars charging rate the question that comes to mind is, what is the associates cost of charging each car vs the cost is buying solar? At the current cost of fuel things are different but what was it when gas was $2.50/gal.? Our electric company charges about $0.0625 / KWH BUT! With taxes and other fees it works out to $0.125 / KWH. As little as we drive (~50-75 miles/week) and the cost of a Tesla I don’t see the ROI at this point. This does not account for miles you can travel on 1 charge and associated travel time required for these trips that would include charging stops vs gas cost and fill ups. Not including battery replacement vs engine replacement down the road. Just some thoughts. I’m not convinced yet electric is the way to go.

[@bigmacntings7451]

that's still darn cheap compared to uk/eu prices. electricity now in the uk is about 35p-40/kwh (and between 7-15p at night) take into account exchange rates and tht's nearly $0.50/kwh!!! batteries like this make a lot of sense if you can charge on the cheap rate at night and use that+solar during the day. you are also lucky in the USA to have so much space, your houses are huge compared to the typical eurpoean home. Actually in europe there's a lot of people live in apartments all over,not just the big cities.

[@SDGreg]

In order to make a Powerwall really beneficial you need to be on Time-of-Use with your Utility. For example for me, from 2pm-8pm each day Mon-Fri is the highest charge for my electrical usage, 48cents. So earlier in the day my Powerwall's will charge from my Solar. Then from 2pm-8pm my house goes over to battery power and I all my solar goes to the grid which gets me the highest net-metering compensation.

[@jeremyjudkins]

I think Powerwalls, despite them not being financially worth it, are super important. For one reason. Without powerwalls, your solar panels are worthless if the grid goes down. People think that solar panels alone can keep your house running during an outage. But you need the powerwalls to act as the "grid." To absorb excess energy and provide energy to the house. I'm in the same boat as you. I get 1-1 credit for my net energy metering, and the electricity is rather cheap at about 10 cents per kWh. But I choose to get powerwalls for the peace of mind. However, I live in Florida so the chances of extended power outages are way higher here. Also too, I have two Powerwalls and my house is only 1800 square feet and I have 1 Tesla. For you to truly be happy with Powerwalls and for it to be a full house backup solution, you would probably need like 6 at minimum. But if two isn't worth it to you, then 6 definitely wouldn't be.

[@revealingfacts4all]

Do you get 1:1 net metering with Duke Energy? I live in Florida too and I went with three powerwalls for a couple reasons. (1) standby power during outages (2) grid to battery during off peak less expensive times then use stored power to offset costs during peak more expensive times. With Duke, I can sell back at wholesale prices which is the price Duke pays, not the price the sell to me. Curious who your power company is....?

I just checked my solar system, it's 21:15 in the evening ( 9:15 PM ) here in The Netherlands and it still produces 15 watt, that's about 1 watt a solar panel, but it's a lot darker here then what I see through your window and you got a lot more solar panels. 10:20 6 cents per kWh? I pay 21 eurocent a kWh at my home in The Netherlands... For 6 cents it's allmost useless to buy solar panels too?! At least from a financial standpoint, unless you're really patiënt. Just wondering, your entire household only has 2 drivers licenses right? And the cars I see have no autopilot right? Why do you have like 4 or even more cars? Around 4:25 -4:55 I see that you are using around 6,5kW at normal conditions, which I think is still very very high, but then I'm not used to a house this size. If you have a power outage you would ofcourse be crazy to charge 3 electric cars and put all of your airco on full power lol, so that's not really fair either. In my house in The Netherlands I can't even use 51kW, it's limited to around 17kW. In The Netherlands we use an electric heat pump, which is essentially both a heater as well as an airco which spreads it's temperature through the floor, also it's like 600% efficiënt, yes really. Somehow to rebuild your house creating underfloor heating is a really hard and expensive thing to do if you do it afterwards. It might somehow be more easy to heat up your swimming pool that way, or cool down your garage relatively efficiënt. It basically works similar as your airco, somehow it doesn't use the air, it uses water from deep under the ground. A heat pump essentially grabs water and splits it up in hot water and cold water after it did that, it uses the hot water to warm things up (your bath or shower or...) and the cold water to cool things down (your garage or ...) the water with the temperature it doesn't need, it simply pumps back in the ground. A heatpump will struggle with extreme temperatures, it can not heat water up till 100 degrees celcius and it can not cool water down to under 0 degree celcius, also, it does need start water above 0 degrees celcius to start with (so no ice), that's the reason why they usuall dig a hole deep under the ground, because deep under the ground it's allways above 0 and the ground doesn't suffer of a cold winter or hot summer, it keeps it's temperature around 17 degrees celcius or so.

[@JBoy340a]

Very good point that it depends on your situation, especially the cost of power. We pay $0.21 kWh off peak, $0.43 on-peak (M-F 4-9 PM). We have 2 power walls and a solar roof. The Powerwall are recharged from solar each morning, and we push solar to the grid from about 12PM-7PM in the summer. We get paid about $5/day for that power. More importantly, the Powerwalls let us not use power from the grid most days. This has reduced our summertime bills from $400/mo to $20/mo. Also important is that the Powerwalls have let us continue working and living our lives on a couple of multi-day power outages. With just solar and no batteries when the grid goes out you lose power even with solar panels. So you end up staring up at your solar panels and the bright sun as you sit in your unpowered house getting more and more upset by the minute.

@@stephensmith777 - I am in California. Those rates are the summer rates July-October when everyone flips on the A/C. The rest of the year they drop to $0.091 off-peak and $0.118 on-peak. Fortunately for us, during the summer period, the solar makes enough electricity to power the house with A/C running and still change the batteries to 100%. We can go most of the summer rate period never pulling electricity from the grid, and selling the excess solar generation back to the grid. BTW, is Virginia power reliable these days? When I lived there we lost power every summer afternoon when the thunderstorms rolled through.

This is why bi-directional charging in Teslas needs to happen, like yesterday. The main reason why most have them is for emergencies. Having basically a Powerwall at the ready per EV defeats the purpose of having a sperate Powerwall.
