Inverters

China’s Guangzhou Sanjing Electric (SAJ) has developed a new line of battery inverters in single-phase and three-phase configurations.

Zigor has developed a modular central inverter that can convert AC power to DC power for battery charging. It has an output of 3.3 MVA and a DC voltage of up to 1,500 V.

The US Court of Appeals has ruled that an 80 MW (AC)/160 MW (DC) solar farm, with 50 MW of battery storage, meets “Qualifying Facility” status of 80 MW (AC) or less under the Public Utility Regulatory Policies Act (PURPA) of 1978.

On the first day of Spain’s Genera tradeshow, pv magazine spoke with Joan Groizard Payeras, Managing Director of Spain’s IDEA (Instituto para la Diversificación y el Ahorro de la Energía) about the current state of solar manufacturing in Spain, and what the government is doing to the make its domestic industry more competitive.

Sunwiz has revealed the leading rooftop solar and inverter manufacturers in Australia for 2022.

GCL-SI says it will build a new 12 GW solar manufacturing facility in China’s Jiangsu province, while Growatt has opened a factory with an annual capacity of 500,000 inverters and 100,000 batteries in Vietnam.

An international research group has developed a new Aalborg inverter design for high-power applications in solar arrays. The device has fewer switches than conventional, voltage-source inverters and can reportedly improve PV system performance by reducing switching losses.

SolarEdge’s revenue rose 58% year over year to $3.1 billion in 2022. It expects revenues for the first quarter of 2023 to be within the range of $915 million to $945 million.

Felix Krause, co-founder the Vireo Ventures, tells pv magazine that the Berlin-based company plans to make pre-seed and seed-phase investments in startups that are developing innovations for the energy transition.

The Bern University of Applied Sciences in Switzerland has published the initial results of a survey on the durability and performance of residential PV inverters and power optimizers over a 15-year period. They found that more than 65% of the inverters did not present yield-relevant faults by their 15th year of operation.
