Scientists in India have developed a 500 W seven-level inverter prototype based on switched capacitors. The device is reportedly able to achieve a high efficiency despite switching, conduction, and capacitor voltage ripple losses.
Exide, an Indian manufacturer, has entered the lithium-ion home power backup market with wall-mount lithium battery inverters ranging in size from 450 W to 720 W.
Section 48 guidance has been released, updating the requirements for the ITC under the Inflation Reduction Act.
Fenice Energy, formerly SunEdison, has developed single-phase and three-phase microinverters for residential and commercial solar installations. The microinverters support up to 670 Wp+ PV modules, with a maximum input current of 20 A.
China’s Guangzhou Sanjing Electric (SAJ) has developed two new single-phase and three-phase all-in-one battery inverters with efficiencies of 97.8% and 98.0%, respectively. They use artificial intelligence to support energy management.
Conducted by Italian scienitists, the analysis includes standards such as IEC 61727, the US EREC G83/2 Recommendations, Germany’s VDE-AR-N 4105, China’s GB/T 19964-2012 and GB/T 20,046, Italy’s CEI 0-21, Australia’s AS 4777.2, and New Zealand’s AS 4777.2 standards, as well as the United States’ IEEE 1547.
Huawei has released a white paper regarding the safety and performance of its Smart Module Controller optimizer series.
Central inverters still dominate the US utility-solar market but string inverters are beginning to get more traction in projects above 10 MW in size.
Chinese manufacturer Hoymiles has announced the North American launch of its new inverters, which are designed for commercial and industrial installations.
