NOTE:
If the inverter displays any alarm message as listed in Table 8.1; please
turn off the inverter (refer to Section 5.2 to stop your inverter) and wait for 5
minutes before restarting it (refer to Section 5.1 to start your inverter). If the
failure persists, please contact your local distributor or the service center.

8. Trouble Shooting
The inverter is designed in accordance with the most important international grid-tied
standards and safety and electromagnetic compatibility requirements. Before delivering to
the customer, the inverter has been subjected to several tests to ensure its optimal operation
and reliability.
In case of failure, the LCD screen will display an alarm message. In this case, the inverter
may stop feeding into the grid. The failure descriptions and their corresponding alarm
messages are listed in Table 8.1:

Solis Single Phase Inverter does not require any regular maintenance. However, cleaning
the dust on heat-sink will help the inverter to dissipate the heat and increase its life time.
The dust can be removed with a soft brush.
CAUTION:
Do not touch the inverter's surface when it is operating. Some parts of the inverter
may be hot and cause burns. Turn off the inverter (refer to Section 5.2) and wait for
a cool-down period before before any maintenance or cleaning operation.
The LCD and the LED status indicator lights can be cleaned with a damp cloth if they are too
dirty to be read.
NOTE:
Never use any solvents, abrasives or corrosive materials to clean the inverter.

Restart<ESC>
Please check DC cables and connections to identify the source of possible arcing. Then
press <ESC> for 3 seconds
, the inverter will restart.
During normal operation, If arc fault happen in DC circuit, the inverter will stop output and
