6.2 PV inverter test
The test is intended to check proper operation of the PV inverter. Following functions are
supported:
Measuring of DC values at inverter’s input and AC values at inverter’s output.
Calculation of the efficiency of the inverter.
With the EurotestPV instrument one DC and one AC signal can be measured at the same
time.
For 3-phase inverters one DC and three AC signals can be measured at the same time
with a combination of a Metrel Powermeter and the EurotestPV instrument. During the
measurement the Power meter and EurotestPV instrument must be connected via cable
or Bluetooth link. At the end of the measurement the results from Powermeter are sent to
and displayed on the EurotestPV instrument
.
See chapter 4.2 Function selection for instructions on key functionality. The input voltages
are displayed in order to check proper connection before carrying out the test.
