Distributed vs. Virtual Central

The “Distributed vs. Centralized” conversation has been heavily debated since string inverter manufacturers began offering 1000Vdc products. Many installers, developers and EPCs had chosen a preferred architecture. However, the introduction of 1500Vdc string inverters into the utility space has changed the dynamics again. These string inverters can be installed in either distributed or centralized architectures by using the virtual central approach. Higher powered inverters, longer strings at 1500Vdc and better communication options are positioning these inverters for use in much larger sites than had been considered only a few years ago. The question is not string vs. central anymore, it is distributed vs. centralized.

In this webinar, we will discuss the benefits and disadvantages to both the distributed and centralized string architectures and how the design choice affects installers, developers and site owners.
