MPI-540 ● MPI-540-PV – BRIEF USER MANUAL
3.18.1 Measurement configuration
Fig. 3.9. Configuration screen of inverter efficiency measurement
Set the parameters of the tested inverter on the displayed configuration screen:
Mains system – there are two types to choose from:
o Single phase, DC + 1-P
Select this system type for inverters with single-phase AC output.
o Three phase, DC + 4-P
It is possible to measure only the efficiency of three-phase, 4-wire inverters (star
configuration with neutral wire).
Manufacturer efficiency – efficiency of the inverter declared by the manufacturer. This value
is used to compare the measured efficiency with the declared value.
DC clamps type – the user may use the list to select the type of clamps used for current
measurements on DC side of the inverter.
AC clamps type – the user may use the list to select the type of clamps used for current
measurements on AC side of the inverter.
Frequency – nominal frequency of the AC output of the inverter.
