Measurement Tolerances

9.2
The data supplied by the inverter may differ from measurements taken by certified measuring instruments (e.g. output
meters, multimeters and grid analyzers). The inverter is not a measuring instrument and has wider tolerances for the
measurements it makes.
Inverter tolerances are generally:

±5% for real-time measurements with output power below 20% nominal power

±3% for real-time measurements with output power above 20% nominal power

±4% for all statistical data
