HDPV Alliance standard aims to decrease inverter costs by up to 50%
By Anthony Capkun
July 9, 2013 – The HDPV (High Definition PV) Alliance—an industry group aimed at “reducing photovoltaic (PV) balance of system (BOS) costs while increasing energy production from PV plants”—published its first inverter standard, saying it contains protocols that aim to help PV inverter manufacturers optimize product functionality to deliver up to twice the rated output power to reduce inverter costs by up to 50%. The alliance says its goals are to facilitate collaboration among member companies to take advantage of distributed power conversion (DPC) architectures, and to make it easy for project developers and integrators to identify and source products that provide the HDPV advantage. Publishing interoperability standards like the new inverter standard supports these goals. This standard is the first in a series of published standards to be released that promise end-to-end compatibility among components involved in distributed power architecture.
