Inverter Interfaces; Commissioning And Activating The Installation - SolarEdge P300 Quick Installation Manual

Inverter Interfaces

The following figure shows the inverter connectors and components, located at the bottom of the inverter. The ON/OFF switch and the LCD
light button may vary depending on the inverter model:

Commissioning and Activating the Installation

1
Verify that the inverter ON/OFF switch is OFF.
2
Turn ON the AC breaker.
3
Move the AC/DC Safety Switch to the ON position.
4
Remove the inverter cover: Open the inverter cover's six Allen screws and carefully pull the cover vertically before lowering it.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the inverter cover is removed.
RISQUE D'ÉLECTROCUTION. Ne touchez pas les fils non isolés lorsque le couvercle de l'onduleur est retiré.
5
Activate the inverter according to the activation instructions supplied in the inverter package.
6
Verify that the inverter is configured to the proper country or grid setting: Press the LCD light button until reaching the ID status screen:
I D : # # # # # # # #
D S P 1 / 2 : 1 . 0 2 1 0 / 1 . 0 0 3 4
C P U : 0 0 0 2 . 0 1 1 1
C o u n t r y : U S A 2
7
If required, perform the following additional steps before closing the inverter cover:

Country settings or inverter configuration using the internal LCD user buttons, located just above the LCD
and are numbered esc, 1, 2, 3/Enter from left to right. Enter the menus by pressing ENTER for five
seconds and then inputting the password 12312312. To verify that the country code is set to USA, select
Country from the main menu, press Enter and select USA+. In the next menu that appears, select the
desired AC grid configuration.

Communication options connection – refer to Setting up Communication on page 6.
8
Close the inverter cover by tightening the screws with a torque of 9.0 N*m/ 6.6 lb*ft. For proper sealing, first tighten the corner screws
and then the two central screws.
9
Make sure the AC/DC Safety Switch is ON. If an additional external DC switch is installed between the power optimizers and the inverter(s)
then turn it ON.
A message similar to the following appears on the inverter LCD panel:
V a c [ v ] V d c [ v ]
2 4 0 . 7
P _ O K : 0 0 0 / 0 0 0
10 Verify that the following information appears on the LCD panel:

Vac: Specifies the grid voltage.

Vdc[V]: The DC input voltage of the longest string connected to the inverter. There should be a safety
voltage of 1V for each power optimizer in the string.

Pac[W]: AC power production. At this stage, it should be 0w.

P-OK: Specifies the number of properly connected power optimizers.

S-OK: Indicates the status of the connection to the SolarEdge monitoring portal (if connected).
WARNING!
Before proceeding to the next step, make sure that the cover is closed! High DC Voltage will be present in the inverter following the next step!
Avant d'entamer la prochaine étape, assurez vous que le couvercle est fermé ! Une tension DC très haute sera présente durant l'étape
suivante !
