I was at the local Tesla store recently looking at those very spiffy vehicles they make. While there, I was encouraged to read about the Powerwall on one of the large touchscreen monitors they have on the wall. Well, so I did.
Apparently the Powerwall is a battery designed to power something like about a whole home for a day. Quite the accomplishment, and surely going to be useful to many folks. Well done.
But, while reading the screen, I noticed something odd. They listed the weight as 264.5 lb/110 kg. Um, without a calculator I could see that was wrong. So, while I am not a tech blogger, I am always interested in products and marketing and the silly things that come out of it (most of these photos show up on my Instagram account for tropicalbats if you are interested.
Anyway, here is a shot of the screen at the Tesla store:

Bad conversion numbers on the Tesla Powerwall specs
Now, after looking at the photo, it is apparent that while the temperature conversions are correct, the dimensions are also wrong. Since the diagram on the left uses inches, I will use those and say that here are the correct conversions:
44" = 1117.6 mm
29" = 736.6 mm
5.5" = 139.7 mm
And of course: 264.5 lbs = 120 kg
So what are the correct numbers? I don't know. I Googled "Tesla technical specs" and got a link to the Tesla site that looked like it had those numbers on it:
Powerwall | The Tesla Home Battery

Powerwall Technical Specs. 44" / 1150mm 29" / 755mm 5.5" / 155mm. Usable Capacity 13.5 kWh; Depth of Discharge 100%; Efficiency 90% round-trip; Power ...
However, clicking to the Tesla site came up with just a webpage where you can purchase a Powerwall but without any specs at all. No help going to the source.
Again, not my thing but I was still curious so I clicked another link to Electrek:
https://electrek.co/2016/10/28/tesla-powerwall-2-game-changer-in-home-energy-storage-14-kwh-inverter-5500/
Which provided this list of specs:
Nonetheless, the full specs of Powerwall 2 are impressive:
44" = 1117.6 mm
29" = 736.6 mm
5.5" = 139.7 mm
And of course: 264.5 lbs = 120 kg

Nonetheless, the full specs of Powerwall 2 are impressive:
- Mounting: Wall or Floor Mounted, Indoor/Outdoor
- Inverter: Fully integrated Tesla inverter
- Energy: 14 kWh
- Power: 5 kW continuous, 7 kW peak
- Round Trip Efficiency: 89% for AC Powerwall, 91.8% for DC Powerwall
- Operating Temperature Range: –20°C to 50°C (–4°F to 122°F)
- Warranty: Unlimited cycles for up to 10 years
- Dimensions: 1150 mm x 755 mm x 155 mm (45.3 in x 29.7 in x 6.1 in)
- Weight: 122 kg (269 lbs)
Which are, correct but, well, not the same as the Tesla numbers and the weight is completely different.
So, there you have it. My big adventure into Tesla conversion specs for the Powerwall ends with me still not knowing what is what. Anyway, good luck installing one in a confined space as it seems like no one knows exactly how big it is.
