Why your next home might be battery-powered - home battery system

The future of home energy is located in the Rockville basement of Josh and Susan Fried, close to the shelves of old tools and canned soup, a box without decoration, size like a wine cabinet full of more than a dozen silent batteries
The retired dentist and his wife were annoyed by the power outage, and they spent $50,000 on batteries and other technologies that could keep their suburban homes supercharged.
Now, if they diede-
Sac lost power and they could run air conditioning, treadmills, and even coffee machines for three days before sweating.
Their electricity bill is also smaller because they can store energy from the production lines of solar panels and Pepco for use when the sun does not shine or the price is high.
When the battery is fully charged, the couple can even sell back some juice and sometimes earn $30 a month.
"The sun came out," said Josh Fried, 67, one day last week.
"I have been selling all day.

Completely changed the lights of the United States.
Homeowners have been using solar panels for years, but the technology has a serious flaw: they can't work under night or cloudy skies.
But by storing solar energy at any time, the battery can help remove the biggest obstacle for mainstream families --
According to a report from the Rocky Mountain Institute, an influential energy think tank, this month, the growth of energy, especially as the prices of these two technologies rapidly decline.
But household batteries have been resisted by large utility companies, which are now in a broad battle with the budding solar industry.

Tesla, a technology company led by billionaire Elon Musk, is expected to become a high-tech enterprise.
Next week, when it launches home batteries based on the same type of rechargeable lithium, industry insiders bet
Ion bricks are found in most modern laptops and mobile phones.
Just like the few batteries on the market right now, Tesla will turn off power to prevent power outages and replace noisy, dangerous gas generators.
But the real potential advantage of the Tesla battery is its "ordinary man simple": the size of a kitchen cabinet, no noise, no maintenance, can be installed in the afternoon.
Trip Chowdhry, an analyst at global stock research, said Tesla had quietly installed batteries in hundreds of test homes in California over the past two years.
He expects the price of these batteries to be between $10,000 and $15,000, but at $20-

Okay, Elon is talking "fool ").
"Batteries have helped to power homes in places where the energy grid is unstable, islands and developing countries, including India and Bangladesh.
But for homeowners in the United States, they are still a niche market. S.
Although the United States is increasingly demanding connection of aging power grids, the power outage rate has increased by 285% since 1984.

The well-known cheerleaders and its booing can make home batteries recognized in the mainstream of the United States.
The electric giant has made a unique start.
Tesla is now building the world's largest battery plant in the Nevada desert, a $5 billion "Gigabit plant," the company said, this will reduce the price of available batteries for homes and cars by more than 30%.
Several companies are already turning to Tesla.

Wal-Mart spokesman Kevin Gardner said.
Mr. Chowdhury said Tesla's batteries had also been installed in Google's office and were in the blueprint for Apple's vast new campus, although neither company would confirm the plans.
Even with Tesla's support, the home battery will still be a shrimp compared to the powerful power grid in the United States.
With nearly 3 million miles of transformers and power lines, it is described by some as the largest machine on Earth.
But, traditional utilities are still concerned about how "distributed energy" for home batteries and renewable energy can weaken their maintenance costs by allowing homeowners to create or store energy without paying the expensive cost of the grid.
The Edison Electric Power Research Institute, a trade group in the utilities industry, said that batteries are one of the real "destructive threats" that can allow taxpayers to reduce their dependence on power lines.
In a 2013 report, the organization said: "In order to better understand this, 10 years ago, who would believe that traditional cable customers could cut wires economically?
Sales of combined solar
GTM Research analysts say battery systems are expected to reach $1 billion a year by 2018.
At the same time, their prices will continue to fall: Rocky Mountain Institute reports that community homeowners from suburban New York to Los Angeles can afford these systems within a decade.
But not everyone believes Americans will buy rivers that store electronics in garages.
Bank of America Merrill Lynch analyst John lovalo wrote in a note to investors last month that the potential market for home batteries is far ahead of Tesla's expectations, adding that household batteries
The success of the battery system is a "long termshot at best.
"If the utility hits or charges extra for the" net metering ", the battery may lose some luster, in which the household sells the energy back to the grid.
The grid itself, with its relatively reliable energy, will also make it easy for Bart's target homeowners to stay away.
"It's hard to compete with the grid," said Peter liantar, CEO of Homer Energy, which provides software and consulting for itself.

Panel contractor, installed 12 inland power batteries designed for the backup electricity.
While they are the only home for miles, they know that the trend of being powered by batteries and away from the grid seems to be in vogue.
Recently, their neighbors held a "solar" meeting at the local community center.
If there is one, it will take a few years for them to make money in terms of energy conservation, but as Susan Fried said, the couple are happy to have "our children --
