Inverters

The Italian manufacturer has showcased a high-power multi-MPPT string inverter and modular conversion solution – designed to supply both decentralized and centralized systems.

Yotta Energy’s new micro-inverter is claimed to be an ideal solution for commercial rooftop PV systems linked to between 500 kWh and 1 MWh of storage. The device has a peak efficiency of 96.5% and a nominal maximum power point tracking (MPPT) efficiency of 99.5%.

Sunil Thamaran, India head for US company Enphase Energy, explains why microinverters are a good investment for rooftop solar. He also talks about the trends in microinverter design and the company’s plans in India.

Furthermore, Zhonghuan Semiconductor has slightly reduced its wafer prices, while Longi has maintained them unchanged. Flat Glass is raising funds to support the construction of a new glass factory with a total annual capacity of 750,000 metric tons.

China’s National Development and Reform Commission (NDRC) has allocated RMB500 million (US$78.1 million) for the incentive scheme for residential PV in 2021. Chinese electronic engineer TBEA is set to raise its controlling stake in polysilicon manufacturer Xinte Energy as it attempts to fund a planned 100,000-tons-per-year fab in Inner Mongolia.

Moreover, Linyang Energy announced a plan to build a 10 GWh lithium-ion battery manufacturing facility in Qidong city, Jiangsu province. Chinese state-owned lender China Development Bank (CDB) has allocated RMB500 billion in special loans to support projects in the energy sector to help China reach its decarbonization targets

Poland-based Green Cell is offering two versions of its new inverter, with power outputs of 1 kW and 3 kW. The inverters feature an efficiency of 90% and are recommended for small buildings such as cottages or year-round homes.

The technology company and inverter maker has created a new unit to operate in the renewables and e-mobility sectors. Elsewhere, China’s largest e-commerce company, JD.Com, has signed an agreement with the world’s biggest wind company, GoldWind, to establish a renewables joint venture.

The two brands announced a strategic project at the SNEC solar conference and trade show which will see the establishment of trading and big data centers to help roll-out PV in China.

The new product has an efficiency of 98.8% and a European efficiency of up to 98.5%. It features 10 independent maximum power point tracking (MPPT) inputs, with MPPT voltage ranging from 180-1000 V.
