Solar plants data integration

Example use case

An asset manager compares inverter output via Modbus, plane-of-array irradiance and IEC 61850 substation data to separate soiling losses from grid curtailment.

Typical sources and transports

Modbus TCP from inverters and meters, IEC 61850 and DCS interfaces, DLMS/COSEM revenue meters, COMTRADE files, BACnet and CAN via gateways.

What the data means

Energy values distinguish AC and DC, interval and cumulative; irradiance needs sensor type and orientation.

Prerequisites

Before connecting solar plants sources, prepare an inventory of systems and owners, interface documentation for each one, read-only credentials and approved network paths. Agree identifiers, units and time zones early, and name a person who can confirm values against the source during commissioning.

Limitations

No plant control or curtailment commands. Some outputs are derived values and are labelled as such.

ALLINLET reads and normalises data; it does not control equipment.
