With comparisons with a Covid-hit 2020 inevitably offering a string of positive numbers, there was also little to concern the board of the inverter and battery manufacturer from the returns generated in the last quarter.

The Chinese inverter manufacturer said the new device can be used for residential and commercial projects as well as to replace diesel power generators or as back-up power. The device features an efficiency of 97.5% and a European efficiency of 98%.

The Italian inverter maker claims to have been impacted by the post-pandemic supply constraints. The proceedings are being managed in full business continuity without any interruption of operational activity, said the legal firm hired by Fimer to implement a debt restructuring process.

In 2002, the Fraunhofer ISE patented the HERIC circuit for highly efficient inverters. Since then, the institute says, it has recorded out-of-court settlements in seven patent infringement lawsuits against companies from China, Taiwan and Germany.

Researchers from German research institutes and companies are working on applying semiconductors based on gallium nitride (GaN) to string inverters with the aim of enabling cost and weight reduction while maintaining very high efficiency. These devices are expected to support grid operations through faster switching processes.

SunWiz has identified the most popular solar panel and inverter brands in the Australian market. In total, 5.2 GW of solar was installed in Australia in 2021, putting the country’s cumulative tally at 26.9 GW.

The BW-HY3600 and BW-HY4600 inverters can be integrated with existing on-grid or off-grid PV systems and a battery storage system of 48V. Both devices, according to German manufacturer Bosswerk, have AC and DC coupling and are particularly suitable for residential and commercial solar arrays.

Called the 1+X modular inverter, the new product can be deployed, by combining eight units, to reach a power of 8.8MW. It also features a DC/ESS interface for the connection of storage energy systems.

SMA’s new hybrid inverter reaches a maximum efficiency of 98.2% and a maximum European efficiency of 97.5%. It is compatible with DC-coupled high-voltage lithium-ion batteries from leading suppliers, according to the manufacturer.

The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.
