I signed up right off for 4 Powerwall 2. I am off grid and my current batteries were failing. Unable to get any useable info other than the initial online brochure, I gave up, cancelled my reservation. Took a couple of weeks to get my deposit back. My new batteries (Aquion) were installed last Wed.

Curious how you have one to sell. My impression they had to be bought with the installation.

'Tis a shame. I would have been a very good advocate. I think I would have been a very good beta site :)

Good thoughts Chris. Unfortunately, I'm running out of time. Due to winter clouds, less sun, and degradation of my batteries, I'm having to run my generator every day. The Tesla configuration calculator suggested I should increase my PV and that would be beneficial with any battery so that is my...

OK, I'm going to agree but perhaps different reasons. It seems that most grid people really don't have a clue what truly off grid means. Any AC power I produce is either via my inverters (powered by my batteries) or my generator, my only choices. A common theme I read in many forums seems to be...

Thank you Miimura, not an easy decision. I've been very excited about the Tesla PW2 and was quite willing to be on the bleeding edge. My Aquion contract is just a few thousand more than my Tesla reservation. Unfortunately, that reservation has changed since I made it and I truly suspect it would...

Chris, my apologies if I come off in a negative way, not my intent, just my frustration coming through. The problem is you don't know same as I don't know, what Tesla may know, but is not sharing. We can only guess. Most current off grid systems and many grid tied (all Tesla) are apple and...

Thanks Chris. You make it sound so simple and straight forward. Please tell us about your off grid system. If using a PW, the DC side details, if not then how you would convert for PW2.

Well time has run out. Unable to find a good source of PW info, even the local installers. So while I had great hope in using PW2 in my off grid environment, not going to happen. Have a contract for installation of Aquion (salt water) batteries in Feb. My current batteries are failing, generator...

I'd personally be a bit skittish signing a contract without knowing the details. I have 4 PW2 confirmed via Tesla and thirsting for info, especially integration into an off grid environment. Having not found any off grid PW1 installed, there is a lack of info. Requiring an additional off grid...

Wonder if anyone has been contacted yet or been able to find out any more specifics other than the little blip on Tesla site?

My reservation # is there, but no details as to how many units or $.

Yep, found the max PV wattage (STC) and amperage in the brochure.

Any chance somebody reading this has knowledge of how the solar side of an installed PW1 is configured. For example ____ strings of ___ VOC x ___ number of panels? If multiple strings are they to some sort of "box" prior to the PW1? If there a min/max PV wattage? Is there a PW install manual...

Bruce, were you able to get any specific info about the Powerwall2 from the rep?

Quite informative slide show. Thanks

Coming from a pure off grid background, perhaps my perspective has been a bit skewered, wondering how the PW2 will fit into my off grid environment. Took a bit of time to learn more about grid tied systems and now see things a bit differently. Whereas what I have seen is along the lines of off...

LOL, unfortunately, I often suffer from "eventually impatience", especially when brainstorming a project. Somewhere, someone has this info now :) I've about got the wife convinced to go ahead and add more panels sooner than later as whatever batteries would benefit. I'm sure she is leaning...

Well, I emailed a local installer who advertises Powerwall with PV install with hopes of gleaning a bit of info - nothing. Said to contact Tesla. No way to do that that I have found. I did go back to the online app no/ordering page and there is a PV calculator I hadn't seen initially. Says I...

So how many kw of PV would be required to support either 95kw or 215 kw powerpacks off grid?

Thanks I suspect that on the PV side it could be as simple as rewiring my multiple 48v parallel strings into higher voltage series strings at the combiner box Currently have 22 strings I guess I either lose strings or add strings depending on values required/supported. Future adding would be my...

Ahhhh, thank you. I remember seeing that, but on my iPad looks like they are on their side. Closer look shows they are standing and somehow mounted together. Like it, even more space saving than I suggested. I'd like to raise off ground level and possibly attach to wall where my Outback is...

I'll have to look for that pic. Thanks

Anyone seen any solid PW2 info since the announcement? Is there anyway to determine who the local installer might be? Any physical configuration info available? I preordered 4 PW2 and would like to look how to configure space wise. Side by side would take about 10ft, not my best choice. 2x2...

Just having an off grid configuration does not mean you do not need UPS if that is important. We are off grid, everything runs from the batteries through the inverter. We have had several instances of losing power for different reasons, the first being a bad cable installation. Took me a bit to...

Actually there is limited Geothermal production here on the Big Island. Supposedly a lot of potential, but a politically/cultural sensitive issue. As for renewables in general, for a long time (and maybe still) the cost of renewables was tied to the fossil fuel costs, hence no savings to grid...

One approach, assuming the new solar roof technology, every house has a total solar roof. Hopefully enough knowledge would be available to accurately predict the daily/monthly/annual production for a particular house based on size/location/etc. Max power consumption would be limited to a...

Off grid with generator. I really think a lot is dependent on your system. I'd have to say many don't have the autostart feature. I know that is very true locally. In my first system, none of the solar components (Morningstar & Xantrax) had that function. My first two Generators were gasoline...

Agreed, which is why I suspect the individuals would maintain a common ownership, but the management outsourced.

I could see where there could be an arrangement with a builder/developer to build out a subdivision away from the grid with a common ownership of the power generation locked into and management by SolarCity long term with residents paying to SolarCity.

Interesting thread. Just a thought on cold temp concerns, what about an insulated box with low wattage heat source (lightbulb?) with a thermostat?

We have a 39k gal inground pool and are completely off grid. When we started building the house, many were eager to tell us that the pool wouldn't be supportable off grid. Being as we had already purchased the pool (it was a kit) before we moved, we choose not to listen. My solar guy suggested...

We try :) Not postcard Hawaii, but suits us. Of course you can visit. Any forum member that books directly instead of VRBO will get a discount.

No typo, FX3048T x 4, the Radians weren't on the product list when I installed my system. Would have seriously looked at it if so as I was aiming to get a top of the line system at the time. My FX inverters are no longer available and should the PW2 not include the appropriate inverter and I opt...

Interesting about the shutdown/restart. Hope they overcome that in PW2. Can't speak for all off grid systems but generator use with my Outback FX inverters is relatively seamless. I do have the option to run in Bypass mode, but in normal mode the generator can start on own and power is shared...

Coming from a personal lack of knowledge here, but Thought it might be interesting if the generator could hook in like grid AC for emergency charging. Of course I'm assuming from what I've read that the PW is capable of charging from its grid source. Not all that different than car charging?

Thanks, that's great news. Near as I can tell not many, if any PW1 configured for off grid. None that I can find on forums. I sometimes get the feeling that sometimes grid tied folks think loss of grid power equates to being off grid, not so from a configuration standpoint. Any hint when more...

Powerwall 2? In your possession?

Ken Yes, I'm worried about the gouging, pretty rampant here in Hawaii. Many Mainland companies think we are ignorant on shipping and have turned it into another profit center. I suspect at very least the $1000 mentioned at the Tesla PW2 page will turn into $1000 per unit plus whatever the local...

Outback has something in the pipeline called Skybox. Limited info on the OB site.

miimura How would you charge those packs? A charge controller? What one? Just trying to get knowledgeable. I know how a conventional off grid system works, but so far at a loss here.

How does the current PW charge from the PV? A direct connection from the PV to PW or you have to supply something in between?

Last time I checked, to replace my current batteries with same would cost me twice what I originally paid or over 20k, hence my interest in new, alternative, especially Lithium batteries. Unfortunately, until the PW 2, all the choices have been cost prohibitive. A neighbor recently went with...

Just signed up for 4 of the new Powerwall 2. A lot I don't know, but appears not a lot of published info available so hopefully signing up will lead to an informed decision. Would really like to learn how to integrate these batteries. Currently live totally off grid on the Big Island of Hawaii...
