Webinar Details

ABB is proposing a new approach to inverter design, which is said to ensure optimal integration with the transformer station. The company claims that its new, Intersolar award-winning PVS-175 inverter intends to enable disruptive system designs, and demonstrates how inverter technology can effectively support the solar industry. But  markets, and the technologies that find acceptance within them, are different all over the world. In this second webinar in our series about the new inverter design we will look into the Asia-Pacific  region. Can Asia, can India, China and even Australia with their gigantic solar plants, profit from string inverters with more power? Are cost savings possible?

In the webinar, we will also discuss  current demand for string inverters in large-scale solar projects with Drag Pandit, Deputy General Manager of a well-known EPC company, India-based Sterling and Wilson, who will share his experience with string inverters.

In a scenario in which system cost breakdown is rapidly evolving towards a higher share for BoS and O&M, ABB is seeking to shift the paradigm in inverter design and identify other areas for cost optimization while preserving the system yield. In the upcoming pv magazine webinar, ABB’s Global Product Manager Marco Trova will discuss the new inverter concept, which ABB says can integrate the transformer station and save on combiner boxes, and explain how this concept is expected to increase yields and reduce costs in large scale projects.

To date, we don’t know of other >100 kW string inverters which have 12 maximum power Point trackers. That’s why we are excited to learn more. Join us for this webinar.


  • Cost breakdown trends in the utility-scale market in Asia and Australia
  • Inverter evolution from component to complete system solution: Inverter + transformer Station
  • How modular construction with detachable wiring box adds further value to a decentralized system architecture
  • How power electronics can enable system-level cost savings outside of the inverter box – comparing to other conventional solutions
  • How to combine 1500Vdc and 800Vac to enable higher power density and cluster capacity
  • Advantages of  multi-MPPT technology
  • How getting rid of fuses and DC combiners can help to minimize EBoS and O&M costs

Questions can be submitted beforehand, or during the webinar through a chat window. pv magazine’s Emiliano Bellini will host the webinar. We look forward to your participation!
