6 Turning the PV inverter on/off
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.
6.1 Start-up Procedures
6.1.1
PV Array DC Voltage Checking
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.
6.1.2
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 "11. Technical data" output section for the utility voltage operating range for your
inverter model.
6.1.3
Starting up the Inverter
1)
Switch on the PV Array switch and DC switch to connect PV Array.
2)
Switch on AC circuit breaker to connect electricity grid.
3)
Communication Module
4)
Upon first start-up of the inverter, country
contact your
please refer to "Get Started
The Communication Module supports the communication with the device with Wi-Fi
function (e.g., smart phone, tablet ect.)
6.1.4
Wi-Fi communication
