Inverters does not show a fault, but shows a status or state which says "Wait AC" or "Wait DC".
If the inverter is showing a status of "Wait AC", consider checking your grid voltage and frequency parameters. If there is no fault code associated, this generally suggests that the inverter is being restricted by "OpMin" or "OpMax" parameters. These define the voltages that the inverter needs to see from the AC grid in order to switch states from "Wait" to "Operation".
This function can be changed permanently for your plant, or by individual devices when needed. We highly recommend reviewing the SMA manuals to fully understand the functions prior to making any changes.
