P3 ............ measured power of phase 3 at the output of the inverter
η…......... .. calculated efficiency of the inverter
U:............. actual voltage on test inputs
Notes:
With one current clamp the complete test can be performed in two steps. Input
should be set to
DC
and
AC
separately.
For the INVERTER AC/DC test fused test lead A 1385 must be used!
For more information about measuring and setup of the Metrel Powermeter refer
to Metrel Powermeter’s instruction manual. Contact Metrel or distributor for
detailed information which Metrel Powermeters are suitable for this
measurement.
5.4 PV panel test
PV panel test is intended to check proper operation of PV panels. Following functions
are supported:
measuring of output voltage, current and power of PV panel,
comparison of measured PV output values (MEAS values) and calculated
nominal data (STC values)
comparison of measured PV output power (Pmeas) and theoretical output power
(Ptheo)
The PV panel test results are divided into three screens. See chapter 4.2 Function
selection for instructions on key functionality.
