Inverters

Chinese manufacturer Deye says its new three-phase residential hybrid inverter system has a rated output power ranging from 14 kW to 20 kW.

Ron Shen, vice president of power electronics manufacturer GoodWe, recently spoke to pv magazine at The smarter E Europe event in Munich, Germany, about the company’s position in the European market and its focus on the fast-growing commercial and industrial (C&I) storage segment.

Enphase says that it has started shipping US-made IQ8P-3P commercial microinverters, supporting up to 480 W of peak output power and compatible with solar modules up to 640 W.

TBEA has developed a new 1,500 V string inverter with a maximum efficiency of 99.02%, maximum power point tracking (MPPT), a maximum input current of 65 A, and a maximum short circuit current of 115 A.

Scientists from Australia’s national science agency and the electricity research and development arm of Google have developed a new ‘smart’ inverter they claim is almost twice as fast and about 50% more efficient than existing commercial inverters.

The new three-phase hybrid inverter series includes five versions with power ratings of 6 kW to 15 kW. They feature efficiencies of up to 98.2% and a maximum input voltage of 1,000 V.

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The proposed technique was found to have a higher efficiency, while providng lower common-mode voltage, leakage current and total harmonic distortion compared to traditional pulse width modulation approaches.

The move follows failed efforts at Intersolar to find an investor or buyer. The manufacturer of micro inverters filed for insolvency right at the end of the trade fair.

Until now, balcony inverters were mostly simple micro inverters, with batteries integrated via MC4 connectors. A hybrid inverter should improve this situation.
