7 Turn PV inverter on/off
7.1 Start-up Procedures
WARNING：BURN HAZARD!
The enclosure temperature may exceed over 70°C while operating.
Danger may occur owing to hot surface. Please do not touch!
After installation, please confirm the AC, DC, and Communication connection
are correct. When solar irradiation is sufficient, the device will operate automatically
after no mistakes on self-auto test (about 2 minutes at 1st startup of a day).
The display includes 16×2 LCD display and LED indicator for inverter status.
There are green and red colors for LED indicator to represent different inverter
working status.
7.1.1 PV Array DC Voltage Checking
1.
Uncover the PV arrays and expose them to full sunlight. The sunlight must be intense
enough to produce the required output voltage.
2. 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 measures 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.
See “11. Technical data”, output section for the utility voltage operating range for your
inverter model.
7.1.3 Starting up the Inverter
1.Switch the DC and AC disconnection switches (breakers) to “ON”.
2.Check the inverter LCD. The startup screen should appear in several seconds,
(for the first time start up, select proper country and language. See “7.3.2 Country
Selection & 7.3.3 Language Selection”).
