3.4.6 The yellow LED blinks 4 times
The yellow fault LED lights up for 5 seconds when the fault occurs, and then starts emitting the
following blink code. 3 seconds off and then 4 brief consecutive blinks. This code is emitted 3 times
in succession. If this fault is still present, the fault signal starts over again.
This code can be caused by either of the following:
• Input voltage has exceeded the maximal permissible limit.
or
• Error in the generator (only applies to SMC 9000TL(RP)-10, 10000TL(RP)-10, 11000TL(RP)-10).
Input voltage has exceeded the maximal permissible limit.
The voltage of the PV generator has exceeded the inverter's permissible input voltage.
NOTICE!
DC input voltage too high. Destruction of the inverter.
• Please contact your installer, who will immediately disconnect the PV generator from
the inverter and check the DC voltage, as described in the inverter installation guide.
Error in the Generator
In the inverter models Sunny Mini Central 9000TL / 10000TL / 11000TL (with Reactive Power
Control) this blink code can occur in combination with the display warning <Disturbance Earthfault>.
This signifies that the insulation resistance in the generator is too low.
Correction of error by installer
Please contact your installer to have the error corrected.
