Ben, The reason your solar is getting shut down is because it’s producing more power than the powerwall can accept. Being disconnected from the grid, that power has no place to go so the solar has to be turned off. You could connect your car and adjust the charging amps used to charge it and allow that energy to be captured in the car & powerwall but it’s a delicate balancing act. Also, turn your water heater off at night and back on when the solar is up to conserve usage overnight. If Tesla allowed a vehicle to powerwall connection, you would be able to use all of the solar power you can generate in a day. Vehicle to grid has many issues but vehicle to powerwall could be seamless.
@HarveyPayne 3 жыл бұрын
I was going to say something similar. My powerwalls get full around noon so it would shut off solar then. If off grid my plan would be to set car to add maybe 10 kwh starting at 11:30 am which should keep the solar running and let me capture that otherwise lost energy.

@@darrellsellers Additional Powerwall is not much help. He’s capturing most of what he’s generating from solar. It’s just that he can’t charge to 100% of the Powerwall capacity due to the slow charge rate. If he added a Powerwall, he’d end up with a 66% charge in the 3 powerwalls and out the extra cost. I.E.; not many additional kWh to carry him through the night. Adding more solar makes the situation worse because higher kw output from solar means the Powerwall has to cut off the solar system sooner as they can’t absorb that much power when they are at a higher % of charge.

Vehicle to P.W. is the way to go for long term power outages. Install one P.W. for short term outages and plug the car into the P.W. for long term situations. With the big car battery as backup users might be able to survive with less panels as the big car battery is there to soak up all the solar the panels can produce. This capability might induce more customers to solar and EVs. Finally, would be interesting if Ben could break out his energy usage, particularly the AC consumption.

With these precautions we can manage indefinitely and comfortably without the grid and still get a useful charge into the EVs.

Find Oct and March are transition months where Nov, Dec, Jan and Feb are all the months my system runs behind production. Can be seen by watching grey bars on weekly charts and when do you take from grid. Planning a backup generator to be able to charge during Oct-March to keep batteries charged if propane cost is below grid. Summer test with full ac raging is pretty cool. Expect months are possible during summer with no sacrifice to energy use. Feels like real energy independence.

Ben - I enjoy watching your all your other videos (on Tesla and others) - I have a pretty similar setup - I tested mine over a month when I got my powerwall setup live in early 2018 - we did our own solar panel setup - permits and electrical work - mostly for the same reasons you outlined that no one will support you later for maintenance or changes. We have 30 panels (10kW) for a 7.6 kW inverter so we over provisioned the panels to compensate for cloud cover etc. Some of those gaps you see could be a result of cloud cover or the solar inverter switching off thinking the battery was already full - you may have to play with the inverter settings on that depending on what model you have. We also have the 2 powerwalls like in your setup. We replaced all gas appliances (water heater/home heater) with heat pump (100% electric) to use our excess capacity fully.

Thanks for this video. I just installed 2 Powerwalls and it took 2 days to charge them with two solar systems. Our original system installed in 2004. It is 18 panels(215 watts each) which is a 3.8kW system. Then in 2019, we added 8 panels(326W each) for a 2.6kW system. Total combined 6.4kW's. The solar company quoted a 12-panel system as the smallest they would install. Like you said, they are in the business of making money. Unfortunately, with the pool solar panels on the roof, only 8 panels could be installed. They agreed to install the 8 panels. It is March 11, 2021, in the San Francisco Bay area, so the system, with the weather right now is working ok. I was trying to find out how long this system would carry the house with an extended power outage. Your video and analysis is very helpful. Thanks so much for doing it.

Great video. I like how you really tested the system out by not changing your daily habits. When we bought our portable generator, I tested it out doing things as normal, just to see how it handled our daily usage. (Don't want to find this out during a real emergency) As others and you have mentioned, adding additional solar panels should help with recharging the Powerwall's to full capacity everyday. My concern with solar and battery back up system, is how will you manage without sun for a few days, in a power outage. Even though you had sun each day during your test, you showed a weakness in the system, a lot of people don't talk about in their review videos. Might want to invest in a portable generator, as backup power, to your solar system. The last thing you want is to not be prepared, if your solar system fails. Our generator is connected to our Natural Gas line, so no need to refill generator or store fuel. (I still keep 15 gal. of gasoline though)

We have very similar Tesla Powerwall/solar panel system setups and we both live in San Diego. October is not an ideal time to do this type of experiment in SD. Its still very hot because of the Santa Anas so you need tons of energy for AC AND the length of daytime gets dramatically shorter as time goes on. Bad combo. I've only had my system for a year now, but from what I could tell June was probably the best month that balanced both relatively mild weather at the beginning of the month with longer daytime. Having said all of that, even then I think 7 days might be risky but I think you'd make it in June. Great video showing the strengths and limitations of the Powerwalls!

In a situation like this would you still be able to access and configure your powerall in case you need to change something?

During a blackout my best was 67 hours 45 minutes with 1 Powerwall 2 and not running the air con. Grid power came back on and ended it.

Hi, Ben, thank you for all the information you provided. Extremely helpful. I subscribed your channel when I saw your other session. While I found this one week experiement you did is VERY interesting and practical. I'm thinking of getting one system in where I live outside LA where should be similar to where you are. I have a few follow on questions on your week long experiment. (1) You mentioned that you didn't charge your EV during the experiment periord. However, I heard you mentioned that the Tesla Powerwall was fully charged around noon time, which means your house was powered by solar from your 16 panels, not powerwall, during the day. So do you feel there might be any extra power (just estimate, since you don't have "sell back" number as you swithed off from the frid) from your 16 solar panels to charge your EVs during the day? Since you work from home, charging EVs during the day or night makes no difference. (2) Also, because the Powerwall can be charged to full around noon, but its level still seems continue to drop at your evening checking point as each day goes by. Does that mean your house's afternoon power consumption is more than that 16 panels can provide, so it has to dip into the Powerwall for energy before the night starts? I saw the weather were similar during these days, and the powerwall was charged to full around noon everyday, so what make it continue to drop? Is it your afternoon usage gradually increased during those days? Or other reasons? I think if your daytime usage is similar, while the powerwall can be charged to full everyday, then if you can make through the 1st day, you should be able to make through each and every reast of days. I'm a bit not clear here. Thank you again, Ben. Hope hear some further comments from you.

Thanks for the experiment! We currently have an 8.84KW system, but no EVs as yet, and since there is no tiered metering in the Austin area, really no reason to justify a Powerwall- our net metering is a dollar-for-dollar trade. But if we can afford it down the road, we would like to add another 5-6KW and a couple of batteries to offset our future EVs. You might consider the same thing- no one will install two panels for your, but if you add another 10-12 panels to completely offset your EV usage, that would probably get it done. And maybe one more Powerwall.

Good experiment but in a blackout or Apocalypse we’d conserve energy no lattes

Great experiment. What software are you using to pull the data from the Tesla app? I have to add up mine by hand and then put it into a spreadsheet. Can the TezLab app do that I some future update? Thanks!

You mentioned upsizing your solar system in the beginning, which I agree with 125%, but in NY the PSC/utility rule was (is?) that it can only be built out to 90% of electric power usage, based on the full prior year. (To counter-act this, perhaps maximize home-charging one or more EV’s the year prior to going solar, and perhaps do some home heating with electricity (I have a portable AC that also can be run as a heat-pump heater) rather than the normal furnace, etc., etc.?)

Great test! I was in the same position we were 100% offset with 10 panels via solar city they said we could add any number of panels anytime. Now owned by tesla they said we need a minimum of 12 panels added but at least you qualify for the tax credit again if you add the whole second system.

Great vid! Question. If there is a power outage in the area and there is no internet service, does this affect the PW ability to communicate with the phone? Cell phone service would be out as well. I guess you are relying on your home wifi to communicate and control the PW.

25 days roughly a month with your usage pattern.that is very good.things will only get better from here in terms of solar and battery

Interesting! I wonder if you’d have made it if you’d conducted your experiment in June-July? I’ve ordered a 10.7kW Solar system with 3 Powerwalls here in FL. I want to power my Tesla Model S with solar, but also need the emergency backup power in case a hurricane knocks out the grid. Plus we have a lot of annoying “mini” outages here in the summertime - Powerwalls should make that a thing of the past. Thanks for another great video!

Ben, I'm sure you know by now but when your solar turned off, based on another video Ive watched from @everyamp, the frequency goes up when battery is full that tells the inverters to turn off since there's nowhere for the energy to go.

Hi Ben, Thanks for all the great information you’re providing with your channel. I was hoping you or some of your followers could help me with my solar needs? I’m in the process of ordering Tesla solar and quite frankly at the same time I’m learning so much...I’m also getting more and more confused. Mostly about the options of what to power with the power walls if power goes out? And, I do live in So Ca, So…My real question is SREC’s! Tesla wants to “Prepay” or credit me in my contract (upfront) but, I would rather be able to sell them on my own, if possible. Hence my question, Does CA offer this?? Incidentally, I’m ordering a 8.16kw solar sys with 2 power walls, I do own a model 3. I look forward to any help you can offer! Thanks

Good experiment. A decade sounds like a long time, but, by the time your tikes are out there, I believe they’d be powering a block with a setup the same footprint as yours.

I would look into unbound solar they do DIY solar adding a few to a current system should be pretty easy project

i have two walls and got to 9 days off the grid and went back when the wall got to 20% charge. i did not make any charges to like style. My solar is 2.45kw solar that is 13 years old. Could go farther if needed.

I know you said that you had the air conditioner running during the test. We in Australia work on C not F so I can only explain it in C. When we run our air conditioning at home, we run it at about 24 C due to the fact that we don’t like to cold and they use less current. I have no idea what temp settings you used but this can also affect your power demands on the power walls.👍🏻
