7 Turning the PV inverter on/off
WARNING !
The internal temperature may exceed over 70°C while operating.
To avoid injury, do not touch the surface of the inverter whilst the unit is
in operation.
After installation, please ensure the AC, the DC and communication
connection are correct. When enough power is generated from the PV
array, the device will operate automatically and will initial ‘self-test’.
This self-test takes approximately 2 minutes and will occur at first start-up
of the day.
7.1.1 PV Array DC Voltage Checking
7.1 Start-up Procedures
Firstly, uncover the PV arrays and expose them to full sunlight. Please note, the
sunlight must be intense enough to produce the required output voltage for the
inverter to start up.
Measure the PV array open circuit DC voltage across the DC positive (+) and
negative (-) terminals.
7.1.2 AC Utility Voltage Checking
Using an AC voltmeter, measure the AC open circuit utility voltage between L1 (L)
and L2 (N) Ensure the voltage is at approximately the nominal value. The inverter
operates with a line-to-line voltage range around the nominal value.
Refer to page 33 "11. Technical data” output section for the utility voltage
operating range for your inverter model.
