The interface is described in its full static extent as a traditional Modbus map.

When used as a dynamic SunSpec Modbus interface, different models, as identified by their SunSpec model identifiers, are present or missing depending on the configuration of the system. The only fixed block is the common model contained in addresses 1 through 69.

The default TCP port for the interface is 5020.

For SunSpec Modbus specifications, see sunspec.org/sunspec-modbus/.

Table 1. Table reading instructions
Value Description
Address Modbus register address
Length Number of Modbus registers for the data
Description Content of the register. Registers that contain measurements provide 1‑minute averages.
Datatype Data type for the content
Unit Unit of measure
Factor

Power of ten to multiply the value with to scale a measurement.

For example, factor −1 applied to register value 123 gives 12.3 as the measurement value.

Fixed value Fixed register value, if any. If fixed value is the same as error value, it indicates that the measurement is unavailable in the product.
Error value Value for an unavailable measurement, either due to a measurement failure or the measurement not being present in the setup.
