6. Troubleshooting
Note:
Never use any solvents, abrasives, or corrosive materials to clean the inverter.
CAUTION:
Do not touch the surface of the inverter it is operating. Some parts may be
hot and could cause a minor burn. Turn off the inverter (refer to Section 6.2)
and let it cool down before you do any maintenance or cleaning of it.
The LED status indicator lights can be cleaned with damp cloth if they are too dirty
to be read.
Solis S6 hybrid inverter does not require any regular maintenance. However, keeping the heatsink
clean will ensure the inverter is able to dissipate heat, increasing the life span of the inverter.
Any grease smudges on the inverter chassis can be cleaned off with soap and water.
The inverter has been designed in accordance with international standards for
safety and electromagnetic compatibility requirements. Before being shipped from the
manufacturing center, the inverter is subjected to multiple tests to ensure operation reliability.

Inverter Shutdown Procedure
Step 1. Turn off the AC breaker or AC disconnect switch to disable AC power to the inverter
Step 2. Turn off the DC switch of the inverter and push in the Rapid Shutdown Initiation Switch
Step 3. Turn off the battery breaker
Step 4. Use a multimeter to verify that the battery and AC voltages are 0V
If the inverter is having an issue, it will show it in one of the following ways: (1) the Inverter (circle)
LED indicator light will flash orange. (2) the inverter status will be an alarm code (3) an alarm code
will display on SolisCloud or (4) the inverter will simply be off. The next several pages explain how to
troubleshoot each alarm code. If it is suspected that the issue is coming from the DC side of the
system, it is recommended to turn the inverter off so that the PV strings can be more safely tested.
If you are not able to resolve the alarm code using the troubleshooting steps, or if the alarm code you
are seeing is not listed, please contact Solis customer support. Use the Bluetooth tool, go to the Info
page and then to the Inverter tab. Scroll down and tap Alarm History and then screen shot or write down
the alarms as well as the dates and times the alarms were thrown.
Please also take note of the inverter model number, serial number, and internal transmitter type.
