Typical applications for 650V Series SiC Schottky diodes include: power factor correction (PFC), buck/boost stages in DC-DC converters, free-wheeling diodes in inverter stages, high-frequency output rectification, and electric vehicle (EV) applications.

“On our system, we have an internal 400-volt bus, and we convert high voltage solar panels to that 400 volts, and then that’s converted to AC,” says Tom Brennan, engineering manager for Sol-Ark. “When we go to the batteries, we focused on a super-efficient conversion method that allows us the highest efficiency directly into a 48-volt battery.” The end result is 95.5 percent efficiency from battery to AC.

“There has been a lot of interest and demand in our H5001 hybrid inverter, but we realize that it does not fulfill everyone’s energy storage requirements. To better serve the market, we added a new stacking feature to our hybrid inverters and are releasing a new AC-coupled hybrid inverter and new batteries,” said Frank O’Young, Darfon associate VP.

The four-day housing, living and furniture expo at the Tatmadaw Hall in downtown Yangon showcased dozens of companies that cater to all kinds of housing needs; from interior decors, construction materials, furniture, kitchen wares, electronic appliances and many more.  

The home battery subsidy is available to all South Australian households and scaled in line with the size of the system being installed. This means that a household with a large battery providing 10kWh of storage is in line for a $5,000 or $6,000 subsidy, the latter one being reserved for concession holders – such as pensioners and low-income homes.

U.S. electric utilities are hit by millions of attempted cyber intrusions a day. While a successful cyberattack hasn’t shut down the U.S. power grid, the Department of Homeland Security in 2017 said Russian actors targeted hundreds of energy and nonenergy companies’ networks.

“The advanced energy storage and software platform will increase ContourGlobal’s wind power production and solar generation energy in Bonaire,” said Giorgio Narminio, Chief Operating Officer at ContourGlobal, in a statement.

Including storage and battery-ready inverters in new installations could soon become even more fruitful than simply avoiding peak time-of-use rates and demand charges. With SEIA leading the way, solar+storage advocacy groups are pushing for nationwide incentives for adding batteries, like a federal investment tax credit for energy storage.

Safety is a concern, as hydrogen is flammable, but so is gasoline and lithium-ion batteries. The transportation of hydrogen for use at refueling stations poses additional safety risks — stations use sensors to monitor for leaks. There have not been serious incidents reported in California, and the industrial sector has been transporting hydrogen for decades.

Why an electric vehicle? Environmentalism and the techno-nerd factor are part of it, but it’s mostly economics. I paid $95k (after taxes, registration, etc.) for my Model S, far more than the @$45k I would typically shell out for a car. The federal government nicely handed $7,500 in tax credits and California chipped in $2,500 reducing my Model S cost to $85k. I also have solar on my roof with extra charging capacity that I sell back to the utility so I have credits to cover charging. When I received an appointment at NASA HQ in December of 2016, my wife and I drove the Model S across country to DC and back for free using Tesla’s extensive supercharger network. (Note: “Environmental” NASA had no electric vehicle charging!) No gas bills for 50k miles driven has saved me $5,000 (assume 30mpg and $3/gal). Model S cost down to $80k. Current Tesla buyers aren’t grandfathered into free supercharging and some don’t have solar but it’s still way cheaper than gas. Analysis estimates charging costs at $4.40 per 100 miles, yielding 68mpg equivalency. So, the gas savings for most folks is more like $2,800.
