Mono vs. multi – How many MPPT-channels are good for my project?

View Webinar Video

Maximum Power Point Tracking (MPPT) is dividing the solar industry. There are ardent defenders of the single MPPT-channel approach and those that cannot seem to get enough channels. To understand the conflict, it is necessary to know how the technology works in string-inverter based utility-scale projects and what it does. Is this a crucial inverter feature, what are the tangible advantages in the design and over the lifecycle of a PV system?

Maximum Power Point Tracking (MPPT) is dividing the solar industry. There are ardent defenders of the single MPPT-channel approach and those that cannot seem to get enough channels. To understand the conflict, it is necessary to know how the technology works in string-inverter based utility-scale projects and what it does. Is this a crucial inverter feature, what are the tangible advantages in the design and over the lifecycle of a PV system?
In this webinar, we will shed some more light and insight on MPPT. Together with our partner for this webinar, ABB, we will dive into various plant layouts and locations and how that affects the requirement for MPPT. Both plant design and surrounding conditions need to be considered before choosing multi-MPPT or monolithic PV array design. This decision will have implications for yield and operating and maintenance costs.
The installation of PV systems in sub-optimal conditions increases the demand for inverters, which are optimized for decentralized architecture plant designs. This is raising the interest in understanding and quantifying the benefit of multi-MPPT technology.

Join this webinar for your deep dive into MPPT and its implications on plant economics.

  • Multi-MPPT as an enabler of flexible PV system design
  • Multi-MPPT as a key factor to achieve maximum energy yield and efficient system design under any system scenario, including sub-optimal conditions: near shading / complex orientations
  • How Multi-MPPT minimizes energy yield losses in case of failures, panel damages
  • Enable fuseless string connection
  • Integrated PV system diagnosis
  • Ideally suited for decentralized “combiner-free” PV system design

Questions can be submitted beforehand or during the webinar through a chat window.

Speakers

Andrea Genovesi, Product Manager – Business Unit Solar, ABB

Andrea has been with Power One since Oct. 2011, where he has initially covered the position of Technical Sales Support Manager for Integrated Solar Solutions until Apr. 2014, when ABB acquired the Solar Energy Division from Power One. He was then appointed technical sales support specialist for string utility solutions that he covered until the summer 2017. During 2017 Andrea has been incorporated with the other team members into the new Solar Marketing & Sales Organization where he is now responsible for the Technical Sales as well as being the Product Manager of Utility Scale String inverters.

Marco Trova, Global Product Manager – String Utility Solutions, ABB

In 2007, Marco was appointed Director of Technical Sales and Service – Renewable Energy Division and covered this position after ABB acquired the Solar Energy Division in 2014. During 2017 Marco and his team have been incorporated into the new Solar Marketing & Sales Organization where he now covers together with the Technical Sales responsibility also the role of Global Product Manager of Utility Scale String Inverters.
