Spare parts are important for quick recovery of important facilities from faults.
When parts in the inverter equipment have broken down, spare parts are required to shorten the mean time to repair (MTTR). Since replacement of individual parts takes much time, it is recommended to replace by equipment. Recommended spare parts for each capacity are shown in Table. The recommended spare rate and minimum amount can serve as the references for the minimum number of spare parts relative to the total number of parts used. It is recommended to decide the amount according to the number of parts used.
For the cell inverter unit, the following measures are taken to prevent trouble when spare parts are replaced. The same applied to the multi-stage equipment.
Replace the failing cell inverter unit with a spare cell inverter unit and restart the operation (to minimize MTTR).
Then, replace the failing parts of the failing cell inverter unit with spare parts
If the failing part is a power device at this time, please request the TMEIC representative to repair it.
