Tesla Wants to Build a Battery for Your House

It also looks like the 10kwh version is only rated at 50 cycles per year.

Bummer.

People are still ling up to buy it.

The green bunch would eat (^%$( if one of their heroes told them it was good.

Now it looks like the 7KWH battery isn't even being offered as a solar option. Solar City will only install the 10KWH "backup" battery with solar systems. So, the 7kwh system is only for time shifting grid power consumption.

People are still lining up to buy it.

"While storing residential power with the Powerwall is still more expensive than grid power, that doesn't mean people won't buy it."

Does anybody know if the proposed PowerWall will integrate with an existing SolarEdge inverter.. to be specific, as this is what I'm getting, the SE10000A-US inverter. I've read that Tesla and SolarEdge will be working together, but wasn't sure if what they had in mind would require a 'new' inverter in order to couple with the battery.

Thanks!

Per their press release, they will be able to retrofit/upgrade existing systems, however it's not clear what is required or what it will cost. Considering the crazy installation price for the battery, the upgrade price probably won't matter to the target consumer...

Ask SolarEdge, maybe they'll say.

Thank you Lucman.. If I was more energetic I probably could have found the info somewhere.

Sunking is a wealth of information..BUT I have heard of ACunits and recently bought 4 Inverter split AC units. 2 x 21/2 hp and 2 x 1hp.. We run one of the 21/2 hp ones about 5 hrs a day. and one 1hp one about 10 hrs a day.. I dont know what that is in the "ton" measurement USA uses.. HP is the only rating used in Phils.. BTUis used mostly for comparison in Australia.
My total monthly electric bill is less than 600kwh a month.
1x50" LED tv on about 12 hrs a day.. usualy no one watching..

Instant electric hot water heater.used at most on 1200 w

2ceiling fans on usually 24 hrs a day.
auto wash machine used 46mins 2 times a week.
1 x 300L fridge/freezer.

All lighting is solar power only... Almost all LED lighting and a few CFL..

Solar clothes drying only as its sunny from 6am to 6pm and above 25deg C about 300 days a year..
Reverse cycle ACunits are not sold or available in Phils..

1 ton = 12, 000 BTU of cooling= 1hp
These don't really make sense with today's efficiencies but they come from the early days of refrigeration when belt drive compressors were used.
A 1 HP motor was needed to spin a 12K btu compressor that was now replacing 1 ton of ice.

It's part of the general polarization of the country, I'm afraid.

I think you just have to accept it, and filter it out when you run into it.

Not really. It is a time where the idiot class has gained more contact with other members of their same class via the internet.

People (like some posters here) who have more time on their hands than they know what to do with research a topic where they have no history and become experts.

I enjoy visiting California, but I have never lived there.

That is where you post from it seems

A friend of mine who got his degree in electrical engineering back in the 70s explained all of this to me today. He wanted to work in commercial generation instead of electronical engineering which is where his peers majored. However, when he graduated, he couldn't find a job so went into IT instead. Later, there were openings in the field but he had missed the boat. Based on this, his explanation of the industry take on new technology makes perfect sense. This kind of technology won't take off with big energy until the next generation inherits the industry. Nukes are the "new tech" of the current engineers in charge. My friend is in his 60s today.

I can really relate to that friend of yours. I graduated in 1976 with a BSEE in solid state electronics. While at college I even worked in a research center on Cadmium Sulfide Solar Cells. But like the power industry the Solid State field had no jobs so I went into power and control design.

Surprisingly while solar was not going anywhere 40 years ago it seems to have risen to a new level and I am glad it finally has.

As for energy "storage" technology, it won't improve until there is a real need. Maybe the time has come for that need but I am still wary of false promises.

It's even a field of study, see e.g. http://nicd.arizona.edu

And I thought it had to do with global Temperatures rising.

Regarding this current line of discussion...

I wonder why there is always so much hostility

Stuntman's been around a couple of weeks, I was following a SHW thread of his.
