Installation and operating instructions

7.2 Mechanical checks
Carry out the main mechanical checks to ensure the inverter is waterproof as follows:
①
Use sealing caps for tight sealing of unused DC input connectors.
②
Make sure the cable gland has been mounted properly and adequately locked.
Make sure the inverter’s communication panel has been solidly tightened.
③
Make sure the AC connector has been mounted properly.
7.3 Start-up
After finishing the electrical and mechanical checks, switch on the miniature circuit
breaker and DC-switch in turn. The inverter starts up automatically.
Usually, there are three states during operation:
Waiting: When the initial voltage of the strings is greater than the minimum DC input
voltage but lower than the start-up DC input voltage, the inverter is waiting for
sufficient DC input voltage and cannot feed power into the grid.
Checking:
When the initial voltage of the strings exceeds the start-up DC input
voltage, the inverter will check feeding conditions at once. If there is anything wrong
during checking, the inverter will switch to the “Fault” mode.
Normal: After checking, the inverter will switch to “Normal” state and feed power
into the grid.
During periods of little or no sunlight, the inverter may continuously start up and
shut down. This is due to insufficient power generated by the PV generator. If this
fault occurs often, please call service.
Quick troubleshooting
If the inverter is in “Fault” mode, refer to chapter 11 “Troubleshooting”.
