5 Troubleshooting SMA America, LLC Position Description Status Explanation Glows for 5 s, High leakage current goes out for 3 s, The leakage current from the inverter and the blinks 6 times PV array is too high. Corrective measures: • Contact installer.
SMA America, LLC 5 Troubleshooting 5.2 Measurement Channels The measured values of the inverter are shown on the display in the measurement channels. In addition, you can read out a variety of measurement channels and messages from the inverter using special communication devices (e.g. Sunny WebBox) or a PC with the relevant software (e.g.
The inverter has disconnected from the power distribution grid or is limiting its power to a defined value over a 10-minute average. The inverter is part of a three-phase system with two further inverters and is equipped with the SMA Power Balancer to prevent the formation of unbalanced loads. Derating...
SMA America, LLC 5 Troubleshooting 5.3.2 Error Messages In the event of an error, the relevant messages are shown on the display and the backlight is activated. Each error message is displayed for 5 seconds. After 5 seconds, the display scrolls through the regular operation messages.
Page 28
5 Troubleshooting SMA America, LLC Message Cause and corrective measures Derating The inverter reduces the output power due to high internal temperatures. Corrective measures: • Ensure that the inverter has sufficient ventilation. • Ensure that air can emerge from the fan guards. If no air is emerging from the fan guards, clean the fan guards (see Section 6.4).

SMA America, LLC 5 Troubleshooting Message Cause and corrective measures Error AFCI The inverter has detected an electric arc in the PV system. The inverter disconnects from the power distribution grid. As soon as the error is remedied , the inverter performs an AFCI test. If the AFCI test is unsuccessful, the inverter keeps restarting the AFCI test until it has been carried out successfully.

5 Troubleshooting SMA America, LLC Message Cause and corrective measures IGBTs The inverter has detected a disturbance in the power electronics. The inverter disconnects from the power distribution grid. As soon as the error has been remedied, the inverter tries to feed into the power distribution grid again.
Page 31
SMA America, LLC 5 Troubleshooting Message Cause and corrective measures REL_INV_OPEN A grid relay does not open. The inverter checks the relays connecting it to the power distribution grid before feeding power into the grid. REL_GRID_OPEN If the grid relays do not function properly, the inverter cannot connect to the power distrubution grid.

5 Troubleshooting SMA America, LLC Message Cause and corrective measures SD-Imax The inverter has detected an overcurrent on the AC side. The inverter disconnects from the power distribution grid. As soon as the error has been remedied, the inverter tries to feed into the power distribution grid again.
Page 33
SMA America, LLC 5 Troubleshooting Message Cause and corrective measures VacL1-Bfr The DC input voltage is too high or too low on the indicated branch. VacL2-Bfr, The inverter disconnects from the power distribution grid. As soon as the error has been remedied, the inverter tries to feed into the power VacL1-Srr distribution grid again.
5 Troubleshooting SMA America, LLC 5.3.3 Resetting "Error AFCI" If the yellow LED is permanently glowing and the message "Error AFCI" is displayed, an electric arc has been detected in the PV system. The AFCI has been tripped and operation of the inverter is permanently inhibited.
SMA America, LLC 6 Cleaning and Care Cleaning and Care 6.1 Checking the Inverter • Ask the installer to check for correct inverter operation at regular intervals. • Check whether there is any externally visible damage to the inverter. If there is any externally visible damage to the inverter, contact the installer.
6 Cleaning and Care SMA America, LLC 6.3 Cleaning the Inverter • If the inverter is dirty, clean the enclosure lid, the display, and the LEDs using only clean water and a cloth. Do not use any cleaning agents (e.g. solvents or abrasives).
SMA America, LLC 6 Cleaning and Care 6.5 Cleaning the Ventilation Grids The ventilation grids must be clean for optimum heat dissipation of the device. Clean the ventilation grids regularly according to the following procedure. 1. Remove the ventilation grids sideways.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help.
