5.3 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 Lite 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 Lite instrument. During
the measurement the Power meter and EurotestPV Lite instrument must be connected
via serial cable or Bluetooth link. At the end of the measurement the results from
Powermeter are sent to and displayed on the EurotestPV Lite instrument.
See chapter 4.2 Function selection for instructions on key functionality.
