The Battery That Can Power Your Home Completely Off The Grid

% of readers think this story is Fact. Add your two cents.


The power of the sun is really amazing and somehow underestimated. Here is the solar panels surface required to power the entire US (100%):

The product is manufactured by Tesla and is a full energy storage system for a sustainable home, as the producer describes it. The solution is called Powerwall, and the concept is simple: The battery charges through solar panels (or through the electrical grid, if you prefer) and acts as an emergency backup electricity supply whenever the power is out. You can use several solar panels and several Powerwall home batteries so that you can go completely off the grid!

Powerwall is easy to mount and simple to use. And the best thing about it is that it can power your entire house as well as the most important appliances that you want to keep powered 24/7. Thus, Powerwall can keep your refrigerator or your freezer working properly during longer outages.

Will it “survive” an EMP? If you don’t have extremely long wires… I think yes! (Read more: EMP Myths and Facts)

Electricity is stored within the Powerwall battery. Then a power inverter converts electricity into alternating current, which fuels your appliances. The alternating current goes through your home’s electrical panel; installing a backup electrical panel can help you use Powerwall to fuel just the selected appliances, and it also protects it from the effects of an EMP.

According to the manufacturer, “Powerwall comes in 10kWh weekly cycle and 7kWk daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with great energy need, up to 90kWh total for the 10 kWh battery and 63 kWh total for the 7kWh battery.”

Here is a short clip from the initial release:

The technical description of the product, offered by Tesla, is as follows:

  • Technology – Wall-mounted, rechargeable lithium ion battery with liquid thermal control
  • Models – 10 kWh, $3,500 for backup applications; 7 kWh, $3,000 for daily cycle applications
  • Warranty – 10 years
  • Efficiency – 92% round-trip DC efficiency
  • Power – 2.0 kW continuous, 3.3 kW peak
  • Voltage – 350–450 volts
  • Current – 5.8 amp nominal, 8.6 amp peak output
  • Compatibility – Single phase and three phase utility grid compatible
  • Operating Temperature – -4°F to 110°F (-20°C to 43°C)
  • Enclosure – Rated for indoor and outdoor installation
  • Installation – Requires installation by a trained electrician; DC-AC inverter not included
  • Weight – 220 lbs. (100 kg)
  • Dimensions – 51.2″ x 33.9″ x 7.1″ (1300 mm x 860 mm x 180 mm)
  • Certification – NRTL listed to UL standards

It’s not very likely to be able to power a standard house with all the appliances we are used to running on a daily basis using just one Powerwall. However, people agree that they waste a lot of energy as long as it is supplied by the national grid. Once their energy source is limited and they start paying more attention to their lifestyle, most people notice that they can maintain a comfortable way of life with much less electricity. A Powerwall combined with solar panels can pretty much preserve your way of life during a massive outage, like the one that would follow an EMP, as long as Powerwall and the solar panels are mounted completely separate from the national electrical grid.

Here is the full presentation, where you can find out more about the Powerwall:

      You can buy a lot of ‘Deep Cycle’ batteries for $3K that work just as well. Or even golf cart batteries too.
      You can get 4 golf cart batteries for around $600. I am a solar geek and was excited to hear about Musk new battery system but I knew it would be expensive. His cars cost about $100K and thats too pricey for me. :grin:

      U-PLUG BLOWS THAT AWAY.
      TESLA WILL OBSOLETE IN A YEAR.
      Tesla

      is toxic chemicals
      U-PLUG
      Is magnets 20lbs and fuel free
      Puts out about 2kw
      Runs day and nite
      Retails for under$ 2000
      Check them out U-PLUG Facebook indigo go
      Can charge Tesla batteries. No heat no radiation no inverter needed, true sine wave
      24 inches by 6 inches
      Free energy is here people
      Magnets.

        I just went to their website and that thing is amazing! As soon as they go on sale I am getting one.
        I am about to buy some property to build my retirement cabin on and its going to be 100% off grid.
        Thanks for sharing!

      None of this will work after a big EMP. A FARADAY CAGE can protect some parts of the system but not all, and an EMP will strike with almost no warning, effecting anything at all that will carry an electric current, from overhead power lines to your tv and fridge.
      Hot Tip :- Use a large galvanized garbage can with a good fitting lid and use it to store a cell phone, charger, small computer, HAM radio, anything electrical/electronic for making contact after an EMP event.

        I was listening to coast to coast am a couple of months ago and they were having a EMP show. A guy called in and said he worked at the hoover dam power station and he said the utility companies have been upgrading their systems for almost 10 years now to prepare for a EMP or a solar flare. He said that all utilities from west to east have been doing that and their systems would act like a circuit breaker and switch over with only a moment of power interruption. That was good news but it still doesnt help our situation when it happens and fry’s our electronics. You still cant go wrong with a faraday cage or wrapping up your electronics up in heavy duty aluminum foil.

        • Uncle Nobby

          I worked on British nuclear power stations which have many more safety features built into them than the original Westinghouse design, and they do not have EMP safety protection, so I doubt very much if the US or Canada have anything protecting their nuclear power plants either.
          And once they blow……….there is no stopping them, see, er, FUKUSHIMA :mrgreen:

      Batteries can be rejuvenated too, check out Tesla Chargers nothing to do with Tesla Motors

      I sell off-grif systems. Here’s what I’ve learned. The Tesla Battery is a 350-400 volt battery that is not compatible with any existing off-grid inverters. Typical systems today operate at 12V, 24V and 48V. Therefore, expect a substantial cost for the proprietary inverter that will be required. That also means you won’t have a wide variety of choices which increases price and decreases features that you would otherwise have if there were competition. These are lithium ion batteries and require a liquid-based cooling system. Lithium ion is not very stable and is prone to overheating and explosions. I sell another brand of lithium iron phosphate batteries that is actually very stable and will last 30 years or more. Do your research before you decide on something like this.

      • Veritas

        Correction, the lithium iron phosphate battery I sell has a 15 year life. The Nickel Iron battery has a 30+ year life.

      Will these panels and batteries BLOW UP like his two rockets??

    • The Thinning Veil Report

      WHY IT DOES NOT MATTER WHO IS ‘PRESIDENT’………

      ANYONE NOT WORKING TOWARDS FREE ENERGY FOR THEIR PEOPLE IS A PART OF THE PROBLEM.
      ANYONE NOT WORKING TOWARDS AN END TO USURY AND PRIVATE CENTRAL BANKS IS THE ENEMY OF THE PEOPLE.
      ANYONE WHO STILL CLAIMS 911 WAS PERPETRATED BY MUSLIMS, IS A PAERT OF THE GRAND CONSPIRACY.

      THIS IS HOW YOU CAN EASILY DETERMINE WHO IS THE ENEMY.

    • Anonymous

      Don’t buy that crap free energy technologies are here
      Save your money for that instead

      • an argie

        This is not free energy.
        Solar Panel are very expensive, let alone the tesla battery.
        Ever heard of Nicola Tesla, Viktor Schauberger or Lester Hendershot?
        They made REAL free energy generator, but the U.S. government confiscated all of it!
