6.1 Start-up procedure
To start-up the inverter, it is mandatory that the steps below are followed in the exact order
outlined.
1. Ensure the commissioning checks in Section 5 have been performed.
2. Switch the AC switch ON.
3. Switch the DC switches ON one at a time. If the PV array (DC) voltage is higher
than the inverter start-up voltage, the inverter will turn on. The red DC POWER LED
and LCD will be continuously lit.
4. Solis inverters are powered from the DC side. When the inverter detects DC
power that is within start-up and operating ranges, the inverter will turn on. After turn-
on, the inverter will check internal parameters, sense and monitor AC voltage, frequency
rate and the stability of the supply grid. During this period, the green OPERATION LED
w ill flash and the LCD screen will show INITIALIZING. This tells the operator that the
inverter is preparing to generate AC power.
5. After the locally mandated delay (300 seconds for IEEE-1547 compliant inverters), the
inverter will start generating AC power. The green OPERATION LED will light
continuously and the LCD screen will show GENERATING.
CAUTION
The inverter's surface temperature can reach up to 75℃ (167°F). To
avoid risk of burns, do not touch the surface when the inverter is in
the operational mode. Additionally, the inverter must be installed
out of the reach of children.
6.2 Shutdown procedure
To stop the inverter, it is mandatory that the steps below are followed in the exact order outlined
1. Press The ENT key to enter internal menus.
2. Navigate to Advance Settings.
.
4. Enter the Advance Settings menu and scroll down to Grid OFF/ON.
5. Use the arrow keys to choose GRID OFF.
6. Technician will see the Green Operation LED go dark. The inverter may indicate a NO GRID
alarm and the technician may see a Yellow Alarm LED illuminate. The RED Power LED
will stay lit until dc power is removed.
7. Turn off the AC Switch to the OFF position.
8. Wait approximately 30 seconds and Switch the DC switch OFF.
9. Confirm all LED's switch OFF (~one (1) minute).
