6 FAQs about [How to communicate data with photovoltaic inverters]
What protocols are used in photovoltaic inverters?
Multiple protocols are available in the industry to enable interoperability in photovoltaic (PV) inverters, including International Electrotechnical Commission (IEC) 61850 , Distributed Network Protocol 3 (DNP3) , SunSpec Modbus , and OpenFMB .
What data does a solar PV plant produce?
Solar PV plants produce a massive amount of varied data. There is tracker data, inverter data, MET station data, internal tags in the controller, data from third parties, and data from the utility. All of this data concentrates into one SCADA platform.
Can a SCADA code be used for PV inverters?
Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have evaluated a prototype code for standard SCADA software to enable the interoperability of PV inverters with other components in the system.
What is NREL's new SCADA protocol for PV inverters?
NREL researchers have developed interoperable SCADA protocols for PV inverters. Two new sets of codes were conceived to enable legacy inverters, which are inverters that are not capable of providing some or all of the grid support functions to participate in advanced distribution management.
What protocols are used in solar PV SCADA?
Common protocols used in SCADA: Modbus and DNP3 are the two most common protocols used in solar PV SCADA systems. Modbus has been around for over 40 years and is open source. This protocol is very widely used for automation components.
Can a single-phase PV inverter deliver 240V or 208v?
In some cases a single-phase PV inverter may deliver power at 240V or 208V across two downstream phases, such as in a residential split-phase configuration in North America. In this case the setting will not be set to Multi-phase automatically and you need to select Split-phase (L1+L2).
