3.4.8 The yellow LED blinks 6 times

Discharge current too high

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 6 brief consecutive blinks. This code is emitted 3 times

in succession. If this fault is still present, the fault signal starts over again.

The discharge current from the inverter and the PV generator is too high. The Sunny Boy / Sunny Mini

Central interrupts grid feeding immediately after exceeding a threshold value and switches back onto

the grid automatically after testing. If necessary, testing will be repeated several times.

Discharge current is dependent on the capacity of the PV generator relative to ground and also

depends on the type of modules and manner of installation as well as the weather conditions.

Therefore, it is quite normal for this value to vary over time.

However, if the inverter frequently displays this fault, please notify the installer who installed your PV

system and clarify the reasons for the high level of discharge current.

This fault message can also be triggered by a PE connection which is not connected to the inverter.

Discharge current

The fault "Discharge current too high" can only occur in transformerless inverters.

Transformerless inverters can be identified by their device designation. The "TL" in the name

stands for transformerless, e.g. Sunny Mini Central SMC 6000TL.

Correction of error by installer

Please contact your installer to deal with the fault or get in touch with the SMA Solar

Technology Serviceline.
