What was found. Initial situation  The inverter was running but the communications for plant management was intermittent.  What actions were taken  The laptop was connected to the U8 port to test the Ethernet cable that goes to the central board. The U8 port was removed and inspected. The Ethernet port on the central board was inspected. The sd card was inspected. Contact cleaner was used on the central board' and sd card slot. The old sd card was removed and a new sd card was used.  What conditions unit was left in  Running with all modules and consistent comms.  Any Future work required if any. Additional information  Continue to monitor the inverter. |  |  |  | #[NAME]! | #[NAME]! | #[NAME]! | #[NAME]! | 2023 | 06-2023 | Incorrect data in coloumn A8 |  | 45114.03333333333
What was found. Initial situation Inverter not running. What actions were taken Tested AC/DC fuses for both modules and were found bad, IGBT'S for module 5 and 6 tested bad. Replaced module 5 and 6 with new ones, replaced all AC/DC fuses with new ones for both modules. Upto- date software version was uploaded on both modules. What conditions unit was left in Inverter running on all modules. Any Future work required if any. Additional information Continue monitoring. |  |  |  | #[NAME]! | #[NAME]! | #[NAME]! | #[NAME]! | 2023 | 06-2023 | Incorrect data in coloumn A9
What was found. Initial situation Inverter running on 4 modules What actions were taken Tested all AC/DC fuses for module 5 and 6 and passed, tested IGBT'S on both modules and passed. Tested fans on module 6 and failed, no output voltage to fans was present. Tested FPGA board on module 6 and was bad. Replaced module (6) FPGA board with one from a bad module. After solving the no voltage issue, 2 fans were not working. What conditions unit was left in Inverter running on 4 modules. Any Future work required if any. Additional information Replaced bad fans for module 6. |  |  |  | #[NAME]! | #[NAME]! | #[NAME]! | #[NAME]! | 2023 | 06-2023 | Incorrect data in coloumn A10
