India implementing its climate pledges well before time, says Javadekar

Union Environment Minister Prakash Javadekar on Wednesday said India is leading from the front and implementing all its climate pledges well before time. Speaking at the inaugural session of the World Sustainable Summit, held virtually and inaugurated by Prime Minister Narendra Modi, Javadekar said India has reduced emission intensity and increased forest cover under the leadership of its prime minister. Four international reports say that India, under Modi, is leading from the front and implementing all its pledges well before time. We have reduced emission intensity, increased forest cover and given a new target for restoration of degraded land and 450-gigawatt target of renewable energy will be achieved. This is our country's ethos, he said. He said Modi brought on the international table for the first time the issues of lifestyle and climate justice. I presented his wonderful book titled 'Convenient Action'. World is talking about inconvenient truth, but the answer is convenient action. I gifted this book to all dignitaries in Paris," Javadekar said. "In the same conference, PM launched international solar alliance, coalition of disaster resilient infrastructure and mission innovation. These three initiatives were also picked up very well throughout the world. India is implementing its pledges, he said. The three-day Summit convened on the theme 'Redefining Our Common Future: A Safe and Secure Environment for All'. RM

India’s Ajay Mathur to take over as ISA chief

Ajay Mathur, who heads the New Delhi-based The Energy and Research Institute, is set to become the next director general of the International Solar Alliance (ISA), with Mauritius withdrawing from the race. ISA, co-founded by India and France, is the first treaty-based international government organization to be based in India. The alliance has become a significant public policy tool for India and is considered a counter to China’s ambitious One Belt One Road initiative. A special virtual assembly of ISA is scheduled where Mathur’s name is slated to be approved and announced, with him taking charge from 15 March, said one of the two people cited above requesting anonymity. Mathur will replace Upendra Tripathy, a former secretary in India’s ministry of new and renewable energy (MNRE). India through MNRE proposing Mathur’s candidature. The directorgeneral has a four-year term, which can be renewed for an additional term. “With Mauritius’ withdrawal, Ajay Mathur is the only person remaining for the top post. He is the right candidate for the job, given his exhaustive experience on the global stage and the technical expertise he possesses," said one of the two people mentioned above requesting anonymity.

SoLiS SEMinaR, EpiSoDE 27 : How DoES a SingLE-pHaSE invERtER ConnECt to SpLit-pHaSE gRiD ?

Press Release

Background In some special countries and regions, the grid structure involves split-phase grid, but if there is no split-phase inverter when installing PV system, can the conventional single-phase inverter be connected to the grid?What problems should we pay attention to?We will share them with you in this Solis seminar. About 120V/240V Split Phase 120/240 Vac split phase is a type of single-phase three-wire mid-point neutral power distribution system commonly found in America with a standard phase-neutral voltage of 120 Vac for residential and light commercial applications. The phase to phase( Live to Live) voltage is 240Vac for heavy industrial loads such as compressors, fridge, and pumps. Because of the 120-0-120 voltage configuration, it is also sometimes referred to as dual-phase, 2 phase / two-phase or even mistakenly, single-phase 220Vac.

How to use a traditional single-phase inverter in a splitphase grid system? Usually, customers in some regions will mistake 120/240VAC for single-phase 220VAC grid.Therefore, the PV grid-connected inverter purchased is single-phase inverter (L+N), which will cause trouble in the installation process, but do not worry about it.The L+N structure single-phase inverter can still be used in 120V/240V split phase power grid. Wiring topology

Figure 2 wiring topology As shown in Figure 2, we only need to connect the Line and Neutral wire of the inverter with the two Lines of the Split Phase grid, and then the PE wire of the inverter is connected with the Neutral of it. About Setting This wiring method does not need any special setting of the inverter, only need to set the local grid standard. Main Menu→Advanced Settings→Password 0010→Select Standard→Select Standard Code→Save & Send; NOTE: In this system,when using the zero injection function, please pay attention to the CT line entry method, which is different from the conventional thread method. We need to loop the L2 cable on the CT, which shown in Figure 3
