Tesla's New Battery Doesn't Work with Solar - Hype & Hokum

Some peeks behind the curtain show that the Wizard of Oz is a little old man...

Even Solar City, the supplier led by Musk, isn't ready to offer Tesla's battery for daily use.

Tesla Powerwall home batteries come in two sizes—seven and 10 kilowatt hours (kWh)—but the differences extend beyond capacity to the chemistry of the batteries. The 7kWh version is made for daily use, while its larger counterpart is only intended to be used as occasional backup when the electricity goes out. The bigger Tesla battery isn't designed to go through more than about 50 charging cycles a year, according to SolarCity spokesman Jonathan Bass.

The 10 kilowatt-hour backup battery is priced competitively, as far as batteries go, selling at half the price of some competing products.
But if its sole purpose is to provide backup power to a home, the juice it offers is but a sip. The model puts out just 2 kilowatts of continuous power, which could be pretty much maxed out by a single vacuum cleaner, hair drier, microwave oven or a clothes iron. The battery isn’t powerful enough to operate a pair of space heaters; an entire home facing a winter power outage would need much more. In sunnier climes, meanwhile, it provides just enough energy to run one or two small window A/C units.

Woah, you mean that the first iteration of a new product isn't a magical energy panacea?

My mind is blown.

Lol - 3 days ago is a long time, eh?

The criticisms you're reading there are just saying you shouldn't use the 10 kWh backup battery pack for daily use, because it isn't meant for daily use. It says nothing about the 7 kWh daily use battery that's, you know, intended for daily use.

Who the fuck has a 2 kilowatt microwave? 2 kilowatts isn't going to run a clothes dryer but its more than enough for a microwave and a vacuum simultaneously. Plus if you are using LED lighting the power draw of lighting should only be like 30 watts assuming you only have 1 or 2 rooms illuminated at a time.

A 2KW vacuum cleaner? Even my 60 litre shopvac is 1350 watts, peak.
