I consult with people who are ready to make purchase decisions on an off-grid residential solar system with an Aquion saltwater battery backup. I can help with Rain Water Harvesting and Storage, Growing your own Food and Storage, Canning / Freeze Drying Food, HD Security IP Cameras, High Power LED 12vdc Interior & Exterior Lighting, High Power LED Flashlights, Backup Generator Install, Rocket Mass Wood Burning Stoves, 4x4 Electric Vehicles (EV) that can be purchased TODAY, DIY Home Health, and a number of other Prepper style topics people are interested in these days.

Doubt many care at this late date, but there was a video - Only 2017 / 2024 Eclipse video taken from the exact conjunction spot:

Paul - Some model/years of the Polaris had various problems with the Canadian made 110v chargers I hear.  I have a first year 2010 model & posted about the overcharging & how to correct it. But I'm also off-grid on solar & came up with a way to plug my EV directly into a charge controller 7 that's works excellent now for fast charging! Retrofitting an old solar battery pack helps with the range. I've had some noise issues & you can see all my videos, but overall I also use my EV daily & still haven't found anything better to buy than what I have. Some have talked about converting a used electric car & I did look at the possibility of using a Smart Car EV. I really need 4WD though the overall size of the Smart might suffice once converted. The Polaris is overbuilt in some areas, but not strong enough in others. It's still not what I want & I hate being stuck with proprietary equipment that's dealer only for example. My idea was to convert an existing gas UTV to electric & that might actually be a good thought long term. I don't need a better EV than what I have, now that I've upgraded the one I have. But I would like a 'REAL' mechanical low range vs High instead of just a switch that reprograms the controller. Lion batteries vs the used heavy Trojans I installed, etc. Cost would be the issue no doubt. There have been better UTV EV's available years past, but they were $30k +. Converting a good reliable heavy duty gas 4WD UTV is probably the better idea, but which one? I don't know much about the gas ones & their history or I might look into it.

Can't find even a picture of any of these batteries on their own website. No videos, whitepapers, trials, university papers, no installs, etc. So I think everyone knows what that means. Show us something real that we can evaluate & then we can compare to Aquion & others. Their own comparison is to Lead Acid, but the batteries for off-grid solar are migrating away to other technologies. We need a comparison to those as well to make a purchase decision..

Can live outdoors all winter ... expected but not yet proven life of 20 years !  Dump them in your garden after they are dead. Completely non hazardous to ship ! Cost is higher than trojans but trojans only last 7 years.  Here is a link   http://www.siliconebatteries.ca/gs.html  here is a link to my local A.E. supplier www.backwoodssolar.com/

I agree on the comment about the powerwall. What's good for cars might not work so well for energy storage at home, & that will bear out with time. I've looked at multiple home storage technologies & settled on the Aquion. I'll be doing videos & articles explaining some of these issues about charge / discharge cycles on Aquion's blog & others each month besides my own YT channel at http://bransonoffgrid.com . Here is my first Aquion article just posted 11/23/2016 - http://tinyurl.com/zdt3auw & the first system I designed using the 30kwh module -

They are not producing a consumer automobile, nor will they produce a workable/affordable storage solution for those wanting to optimize energy usage or stabilize/pre pay permanently, cost.

Its called "Industrial Engineering"

"Industrial engineersĀ are the bridge between management goals and operational performance. They are expected to exert leadership in workplace education as well as analysis, design and implementation of systems and plans for operating those systems that bring value to the organization."

We sized a medium commercial battery system, pretending inverters were available, and found we needed 54 7kw power walls!! I have no interest in wiring that mess. We found the same storage in 8 modules of aquion batteries, available to purchase and operates at common dc voltages.

Please stop waiting on tesla to provide unobtainium, decades are passing by....

The guys at evtv have some great tech. They have some insight on us controlling our transport and home power. Great reading and vids there.

I use the Aquion saltwater battery module in off-grid installs & I've looked at probably all competing products over the years. There is no apple to apple comparison on the different technologies available because they all have their specific advantages & disadvantages depending on the requirements of the particular installation. I like the Iron Edison batteries & Redflow flow batteries as well as others, but I do residential off-grid consulting so I'm helping normal homeowners say in a 2000sqft 3Br house cut their ties to the power co & do their own thing. Someone mentioned they come on a pallet & yes, that's what I normally install. The latest Aspen 48M is 30.6 kwh of storage which can easily get you through summers where you have mostly sun, but it's more efficient to parallel at least 2 or 3 of these & I'll be doing videos & articles explaining some of these issues about charge / discharge cycles on Aquion's blog & others each month besides my own YT channel at http://bransonoffgrid.com . Here is my first Aquion article just posted 11/23/2016 - http://tinyurl.com/zdt3auw & the first system I designed using the 30kwh module -  
 These batteries have been on the market since mid 2014, so they have a track record in large industrial settings, but few in residential just yet because they are just gaining momentum in that market. Your typical local solar installer doesn't usually embrace new technology when it first comes out no matter how good it looks. They usually wait for the commercial installers to get systems using the technology up & running; then after a few years they get feedback from these people to see if they should use it based on how the tech is working. So maybe in 2-5 years from now your local solar installer will offer Aquion, IE, & Redflow as options to Lead acid. I'm sure the Tesla Powerwall will sell a good number as well, but I just do off-grid systems & don't think Lion in any of the current formats is better than the 3 I just mentioned. Your results may vary. If you're really going to be off-grid then you should talk to someone who lives off-grid & learn from then in the same way that if I want to learn permaculture I come here to learn from people who have actually been doing it.

I live very close to your property no doubt & might be of some help to you. For sure if you're going to install a solar off-grid system at some point we should talk. David - http://bransonoffgrid.com
