Riso The electrical insulation between the PV plant and ground is faulty.
The resistance between the DC plus and/or DC minus connection and
ground is outside the defined limit range.
Corrective measures
• Check the insulation of the PV plant.
• Check the PV plant for ground faults as described in section
9.3.1 "Checking the PV Array for Ground Faults" (page 74).
ROM The inverter's firmware is faulty.
Corrective measures
• If this disturbance occurs frequently, contact the SMA Serviceline.
Shutdown Temporary inverter disturbance.
Corrective measures
• Contact the SMA Serviceline.
STM Timeout Internal program run disturbance.
Corrective measures
• If this disturbance occurs frequently, contact the SMA Serviceline.
Trafo-Temp-F Temperatures in the transformer have exceeded the acceptable limit. The
inverter stops feeding the grid until the temperature lies within the
acceptable range.
Corrective measures
• If this problem occurs frequently, check the heat dissipation of the
inverter, as described in section 8.2 "Checking Heat Dissipation"
(page 61).
Trafo-Temp-W If the transformer reaches an inadmissibly high temperature, the inverter
stops feeding the grid until the transformer has reached an admissible
temperature and the plant can begin feeding the grid again. The "Trafo-
Temp-W" warning is displayed until the device is completely switched off.
Corrective measures
• Check the heat dissipation of the inverter, as described in section
8.2 "Checking Heat Dissipation" (page 61).
