solar inverters

Researchers from the U.S. National Renewable Energy Laboratory have developed a tool to balance customer curtailment and grid stability. The “Precise” tool for utilities provides unique inverter settings tailored to each customer, with minimal investment and labor for companies that use it.

A U.S. research group is now developing new inverters to protect solar installations from cyberattacks. The researchers also aim to create new cybersecurity standards. Professor Alan Mantooth, the group’s research coordinator, said that inverters can be shut down if they are hacked, or contribute to grid instability and result in the overcharging of batteries, while potentially creating problems that we still don’t know how to address.

The company has warned shareholders about the potential affect of the virus on its operations in the first half of the year but said Chinese operations had almost returned to normal.

Italian inverter maker Fimer has completed its purchase of ABB’s manufacturing and R&D sites in Finland, India and Italy, along with 800 employees in 26 countries. Fimer said the combined business will ship more than 7 GW of inverters this year.

Lack of flannel in the latest quarterly and full-year filing indicates the Israeli inverter maker is happy the figures speak for themselves. The company is in an expansionary mode as it enters the energy storage and electrical vehicle markets with cash from its financial warchest.

The Swiss-headquartered technology corporation is restructuring, stirring up the figures. That effect was amplified by acquisitions and sell-offs last year with ABB announcing in July it would hand over its inverter business to Italian company Fimer.

The approach combines virtual impedance and a modified pulse-width modulation strategy to suppress fault currents in grid-connected PV systems.

The Chinese solar PV inverter manufacturer officially opened its first non-domestic fab today: a 3 GW central and string inverter factory in Bengaluru, Karnataka. It is targeting a 50% market share in India in 2019, and mulling setting up an R&D center in the country. pv magazine attended the inauguration.
