Replacing the String Fuses
For optional version inverter, it is necessary to replace the blown string fuses due to
overcurrent.
Step 1 Disconnect AC circuit breaker.
Step 2 Rotate the DC switch to the “OFF” position and then pull off all the PV string
inputs
Step 3 Wait for at least ten minutes.
Step 4 Open the inverter as described in section “8 Disconnecting, Dismantling and
Disposing the Inverter”.
Step 5 Observe the string fuse assignment and check the fuse conductivity using
the multimeter. A non-conductive fuse indicates a fault in the affected string.
Step 6 Check the affected string by installer of the PV generator and replace the
defective string fuse with same specification (order from Sungrow).
Step 7 Remove the blown string fuse.
Step 8 Insert the new fuse into the fuse holder.
Step 9 Close the inverter and startup the inverter again.
Clean Air Inlet and Outlet
A huge amount of heat is generated in the process of running the inverter. The
inverter adopts a controlled forced-air cooling method.
In order to maintain good ventilation, please check whether there is anything
blocking the air inlet and outlet.
Clean the air inlet and outlet with soft brush or vacuum cleaner if necessary.
