Apologies, I think I got confused between car and home battery warranties and I’m told the Powerwall warranty is 10 years and not 8.
I wanted to add PW3s to my existing Enphase PV system with their IQ8A micro inverters and was just informed the PW3 currently doesn't work with my gear (12.5 kWh PV system about 25% more generation than consumption with NEM). So my installer suggested some Enphase 5Ps or the PW2. He did say the PW2 would be much cheaper offer more backup power and take up less wall space in my garage. So he's working up an estimate. In addition to the 30% tax credit I was informed my local utility will give me a $300 per kWh CASH REBATE, so I'd be getting $9100 back as a CASH REBATE. I can get two PWs for a few thousand less than a noise 24kW generator. So while I wanted LFP I can live with the PW2 given it will be installed inside a finished garage. Great video and you answered all my questions, especially the Phone Pairing info.
That's really interesting. We don't have Powerwall 3 available here yet. Thanks for the info.
Thanks, this was very helpful information for a beginner like me.
Glad it was helpful!
Hi Lee. FYI, I also didn't qualify for a battery rebate, because I already received a (much smaller) rebate on my solar panels (this is in Melb BTW). However, I am a TSLA shareholder, and me being rather brazen, spoke to my Tesla liaison person to see if I could get a shareholder discount - and the answer was YES (after I proved I actually had the shares). I got $1000 off the INSTALL (not the battery itself) which is really pedantic to be honest. I didn't care where it came from, but I paid $1000 less. Happy days! Like they say, if you don't ask, you don't get. Regards, Greg.
Wish I’d thought of that. Though I don’t own any Tesla shares.
Thankyou so much for the advice with the Powerwall 2. I just had one installed yesterday and am waiting for electrical check and switch on. Can’t wait to see how much it’s going to help with power bills.
Glad you found it helpful, we've been very happy with ours. Hope you're gets turned on soon. ☺️
The Tesla Powerwall has been great. We have had one for 5 years and added a second unit a couple of years ago. Best savings for us on a time of use tariff and a virtual power grid agreement. Battery warranty is 10 years. We had a grid outage for 10 hours during daylight and charged our car, ran the house as normal and kept the batteries full until power returned. The whole system should pay back when including solar plus battery plus electric car.
That’s great to hear. 👍🏻
Sorry, I meant an 8 hour outage. It was a scheduled outage by the network provider for major work. I estimate that the whole system should pay back within the 10 year warranty period.
Why get a Powerwall ? Two reasons mainly, firstly, whole home backup if there is power failure (and I have a lot). The second reason is environmental, meaning, when the sun goes down, the powerwall kicks in, it replaces all the peak (read expensive) grid power that used to come in to power the house (all night). No power coming in means no pollution is happening thanks to me / Powerwall. As for finances, I seriously doubt I will ever recoup all of the costs, but that's not why I got it.
Hi Lee. With regards to the 2 days of clouds, I monitor the wholesale price, and recharge from the grid at the lowest possible price if necessary. But, even with the clouds, power is still being generated by my solar, further reducing what I may get from the grid. So far this year April 2024, I have used $4.76, but exported way more than that (at super peak rates)...
👍🏻
Thanks for the great review! You've convinced me to get one 😂
Forgive my cynicism, but I am cynical. 🤣
@@notacarguy_au You've definitely convinced me to look into it, both for home and business. 😂
@@ashmodownunder It's a shame it's so expensive cause it's really good. Remember that Tesla isn't the only company out there doing this. There are other options you can look at that may not cost as much or meet you needs better.
@@notacarguy_au We wary of anything with LG batteries in them. There is massive recall happening as of April 2024
Thanks Lee. Very useful! Will fwd this to the wife and hopefully convinced her down the track lol.
Good luck! 👍🏻🤞🏻😀
Naa, why bother... Just make an executive decision, and start wearing a bike helmet at all times ;-)
Grid charging is only about the battery. When turned on it can pull power from the grid to recharge the battery either to replenish your backup percentage or in time based control mode it can use grid power when it's cheap if it doesn't think there'll be enough solar to charge and get through a peak pricing period. With grid charging off, the battery will only charge from solar. Your house can still use grid power when you get to your backup reserve or when time based control thinks the grid is the more advantageous option.
Thanks for the clarification, I guess since I’ve always had it on off grid mode, I never really noticed. Only tried the timed thing for one night when we first got it up and running to see how it worked.
Lovely video mate, Did I hear right when you said something about Enphase microinverters. Do they work with Tesla powerwall and what are the issues you may have?
We do have the Enphase microinverters, they work perfectly fine with our Powerwall. What they don't work with is the app ChargeHQ. I believe it's because Enphase has not made the API that ChargeHQ need to work with them publicly available.
Great video, very informative. One question: Do you have a standing charge from the electric supplier even if you don't use any electric. Thanks
We do have the daily charge but luckily we get enough money from our feed in solar that it covers that charge. So for now our account is in credit. Might be a bit touch and go during the winter months. Will see how it goes.
Great video i could never find out why i needed to pair my phone for off grid that was very clear , Thanks .
The problem i have in the UK is when i try to add my none Tesla car and electric billing it's all for the US its asking for my State and Zip code so i cant get passed that . How did you set it for Australia ?
I don't think I needed to do anything. It was just already set for Australia. Perhaps reach out to your installer and check with them? I may be remembering wrong, it was quite a few months ago.
25:14 10 years with 70% capacity if used normally.
38MWh or 10 years if used for other ways (eg. VPP, etc)
Thanks. I think I got confused between the car battery and the powerwall. Apologies.
This is why I didn't join a VPP
@GeoQuacks we are at 17.3MWh at 6 years. Ain't going to reach 38MWh by 10 years.
@@scotty9946 yes, I am hitting it pretty hard with time based control and I'm tracking at about the same usage at you in it's first 90 days. I didn't know this when the bonuses were on offer to join a VPP. It will get worked harder over winter; we use electricity to heat our house and I think it will routinely do more than a full cycle per day.
@@scotty9946 also, how is your capacity tracking?
Interesting video. I'll wait till they are cheaper. On another note, have you noticed the mobile connecter is now charging the full 10 amp with the 10 amp tail? Rather than only 8 amp. For about a week now.
I haven't used my mobile connector in about 16 months, so I have no idea about what it's doing. 🤣 Thankfully I haven't had a need to use it.
@@notacarguy_au It's all I'm using at the moment. Nothing fancy. Doing the job!
Interesting 👍. We have had SolarEdge Solar Battery for the past 12 months . No blackouts in our area yet. However no power bills either just $400 credit. We recently switched to Amber Electric (wholesale ⚡️). This seems to work well🔋. Have you considered switching to Amber?
That’s for the info. I hope that there will be more and more options for folks. I have thought about Amber a few times, but from what I’ve seen it seems like you need to pay attention to it as the prices switch from positive to negative. I know some folks have created scripts and all sorts of clever things to automate it, but I am not that clever. ☺️
@@notacarguy_au SolarEdge has automated negative FiT curtailment because SmartShift controls the solar inverter which controls the battery. But Tesla Powerwall doesn’t (separate inverter for battery and solar)- Yes. would need to monitor . This may change when Powerwall 3 arrives later this year.
Thanks for the insight.
The Powerwall settings part of the Tesla App is still a little confusing. Not sure how to interpret Virginia Dominion’s power bill for the Tesla App settings.
Sorry I am not sure I understand, is Virginia Dominion your power supplier?
Does anyone know if Tesla increased the maximum output power of the Powerwall 2?
I had one installed last month, and the electrician thought the output had been increased to 6kW continuously in the latest firmware update. I've seen it suggested on some websites that Tesla did increase it, with Wiki saying "Powerwall 2 shipped after November 2020, had the same capacity, but can deliver 5.8 kW of power continuously and up to 10 kW of peak power."
But I can't find this anywhere on Tesla's website, all their documents still say 5kW with 7kW peak.
I would go with what the Tesla website says and it says 5kW.
Hi sir i am living in abu Dhabi I am from Pakistan i want tesla powerwall 2 so how can I get please help me thank you
I'm sorry, but I am in no way connected to Tesla the company. I would suggest you contact your local reseller for Tesla products.
15:00 I must live on the edge. I have it set to 0% and regularly during winter drain it too 0 🤣
A braver man than me. 🤣
@notacarguy_au we've had it for 6 years. So we have pretty much done every test to it. 😂😂
@@scotty9946 I have only had my Powerwall to 0% once, and that was because my missus plugged in the car, and sucked all the juice out. My bad for leaving my backup at 0%
What if you have an EV that has V to L? Not as convenient but will suffice through most blackouts. Note Tesla does not have this ability!
Yes, it’s a real shame that Tesla’s don’t support V2L, but that would only really work as a temporary solution for power outages. The thing with using V2L at least as it stands right now is that I think the most you can get out of it is about 3.6kW from the KIAs and Hyundais. Most houses will use more than that from time to time. Not often. Most of the time our houses doesn’t use more than 1kW, but I know our oven pulls almost 4.5kw for a short amount of time when it is warming up, so we couldn’t use that with V2L.
So I think if you’re looking to use a battery as an everyday solution to not have to use grid power, than a home battery is a better way to go.
