Webinar: The Virtual Central Inverter: Using 1500VDC String Inverters for Utility-Scale Solar Projects – December 7, 2016

Wednesday, December 7, 2017
11:30 am EST / 8:30 am PST



At what point do the total installed costs make it wiser to go with central instead of string inverters? With new higher output, 1500VDC string inverters hitting the market, string inverters can be combined to create a “Virtual Central Inverter”, a system design concept developed by Sungrow. The combined set of string inverters would be controlled as a single, power conditioning system through a single, SCADA interface, creating one point of command and control for the entire group of string inverters. The end result is a solar PV system can reap the benefits of both string and central inverters. This webinar explains the “Virtual Central Inverter” design concept in deeper detail, an idea which illustrates how string inverters may soon be the ideal choice for utility-scale PV projects of the future.

What webinar participants can learn:

  • Learn about Sungrow’s “Virtual Central Inverter” concept, which combines Sungrow’s 125kW string inverters that operate with one point of command and control for the entire group of string inverters
  • Advantages and disadvantages of central and string inverters
  • At what point do total installed costs justify the use of central inverters, and can string inverters be used for utility-scale projects?
  • See how a “Virtual Central Inverter” can reap the benefits of both central and string inverters, thus improving system energy throughput and increasing ROI
