Installation Guide
ON/OFF switch: Turning this switch ON starts the operation of the power
optimizers, enables power production and allows the inverter to begin
exporting power to the utility grid. Turning it OFF reduces the power optimizer
voltage to a low safety voltage and inhibits exportation of power. When this
switch is OFF, the inverter control circuitry remains powered up.
LCD buttons: Used for accessing configuration menu options and displaying
status screens, as described in
Configuring the Inverter
on page 49. Pressing
these buttons produces beeping sounds and lights up the LCD for 30 seconds.
Communication gland: For connection of inverter communication options.
Refer to
Setting Up Communication
on page 70 for more information.
Drain valve: Drains any moisture that may be accumulated in the unit.
LCD panel: Displays inverter information and configuration parameters
LCD LEDs: Three LEDs located to the right of the LCDindicate the following
inverter statuses:
Color Description Functionality
Green Power production
On - The inverter is producing power.
Blinking - Standby mode. The inverter is in
Standby mode until its working voltage is
reached. The inverter then enters Production
mode and produces power.
Off - The inverter is not producing power. This
may be during Night mode, when the inverter
ON/OFF switch is OFF or when an error occurs.
Yellow
Communication and
inverter shutdown
Blinking:
Monitoring information is being received
from a power optimizer.
The inverter is being shut down.
Red Fault
On - There is an error. Refer to
Errors and
Troubleshooting
on page 81 for more
information.
Blinking - The inverter is being shut down.
All LEDs turn on while the inverter is being configured.
DC Safety ON/OFF switch: connects and disconnects the DC power of the
system
