Installations Of Tesla Powerwalls Starts In Germany

Don't Have $3,000 Or More Than A Year To Burn? You Could Try To "Build Your Own" Powerwall

Tesla Powerwall & Tesla Model S

Installations of Tesla Powerwalls – which are home energy storage systems – recently began in Germany.

Germany is the largest and probably the most important European market from business point of view for the company looking to get into the ESS space.

Installations are conducted by local certified installers. One of them, Praml reported the two first projects completed. On the photo above you see system combined with solar inverter.

According to the source, two people can install the Tesla Powerwalls in around five hours.

The battery pack is liquid cooled, which causes “light noise”, so it’s good to install it in the garage. The specs prevent operation of the Powerwall under -20°C (-4°F), so in the winter temperatures for much of Europe it could go lower that that threshold from time to time, which is another reason that makes garage right choice.

Praml states it has completed more than 300 ESS installations prior to their Tesla contract.

The other certified installer we know of in Germeny is Memodo, of which recently received delivery of some 25 Tesla Powerwalls (see video).

Wondering how difficult it would be to create a version of the Powerwall that could be:

1. Easily unplugged by the customer

2. Put into a small, modular two wheeled trailer (maybe holds 2-3 Powerwalls?)

2a. These packs would be used to extend the range of a family BEV for long trips.

3. Easily hung back on the wall when the trip is over and the family is back home, to continue powering their home / EV.

Or just mounted on a smaller version of a trailer like this

Or bigger range batteries 😉

hardly necessary though as the infrastructure and charging times improve

I’d rather drive a lighter vehicle every day and use the rest of the battery for everyday home storage, tied to the grid.

Something like this is already in a trial phase.

Way too costly and the cells are not designed for that.
Instead buy some used Volt packs are going under $150/kwhr on ebay.
Next anyone that takes over 1 hr by 1 person to install a PowerWall is an idiot.
It is just bolt it on the wall and run wires to it.
What is so hard?

1 to 4 Powerwalls could be mounted on the Airstream trailer that the X pulled during its unveil last year. Is it safe and legal to use while being towed? I don’t know, but it would let people sleep and enjoy the trailer with Heat, AC and TV, while en route to the next campground. That’s a winner!

So since the inverter is not included, what kind of inverter is recommended to pair with these things stateside? Any links?

I don’t know what inverters Tesla recommends for it Powerwalls, but Tesla chose Dynapower inverters (made in the U.S.A.) for its Powerpacks. I don’t know if Dynapower offers an inverter that is sized for or compatible with a Powerwall.

Perhaps research what inverter Solarcity is using when it installs a Powerwall for its customers.

With an average price/kwh for electricity 3x higher than the US, Germany is a prime market for such storage.

Here are the numbers for 2014. I looked around a little and found that Denmark has now a lot of wind power, and therefor decreased their energy costs.

“perhaps Denmark’s pledge to quit fossil fuels entirely by 2050 really is within reach.”

Norway was in WSJ last week, looking to spend 1.2bb on 1.0GW of land-based wind power. 35 cent equivalent kwh rates is abject failure, of project finance. The quote above, should provide wholesale kwh for 5-7 cents each. The policy mistakes aren’t because of renewables. This is without any tax-advantage.

The Tesla earnings call was bullish on what PowerWall is doing to grow auto-customers. There are a lot more solar users, than Tesla drivers, in Germany. The marketing effect ‘teslaenergy’ has on cars is a good one.

Yes Germany has the highest per capita solar power usage and these home energy systems will be put to better usage there.

Hopefully the office buildings can also install these chargers.

This will cut the usage of natgas in peaker plants.
