1 TABLE OF ALARMS ALARM DESCRIPTION 0000H alarms 0001H Insufficient input voltage. 0002H Grid frequency out of range. 0004H Grid voltage out of range. 0008H Over current in the inverter bridge. 0010H Over current in the DC/DC converter. 0020H Insulation fault. 0040H Grid overcurrent. 0080H Overtemperature. 0100H Bus overvoltage 0200H Configuration change 0400H Manual shutdown 0800H Hardware error 1000H Instantaneous grid over current. 2000H Detection of island mode operation 8000H Hardware fault alert The installer has instructions for the proper response to each alarm. The value displayed in Inv. Alarm can be result of the (hexadecimal) sum of two or more of the values listed above. For example: Alarm Inv. 0006H means the grid frequency and voltage are out of range ( 0002H H )

3 R Process can you communicate with the inverter desired? Communications Troubleshooting Download data of the inverter using Ingecon Sun Manager. You can download it on the screen "online" Alarms? You have to use: L Process Installation manual Ingecon Sun Lite Communication accessories manual is necessary upgrade the firmware? are you using GSM? Local assistance is required You have to use: L Process Installation manual Ingecon Sun Lite Communication accessories Installation manual Firmware Upgrade. Trin#15 has been solved the incidence? R Remote Ship the inverter to be repaired on Si Clean service

4 0001H 0002H/0004H/ 0006H 0008H 0010H 0020H is the inverter displaying alarms? L.1 L.2 L H 0080H 0100H L3 L.5 L3 0200H L H Initial check list (Trin#18): Reception of documentation supplied by the customer. Annex#4 Status of the enclosure. Analysis and diagnosis of damages on the inverter. Annex#3. Start the inverter using start/stop Reception & unpacking 1000H 2000H 4000H 8000H L Process L.2 L.2 L Break down your alarm on individual alarms. Solve each individual alarm using this document 0800H

5 L.1 Process 0001H Insufficient input voltage is the inverter displaying Vdc < 125V? DC voltage out of range is the inverter displaying Vdc > 550V? DC voltage out of range Is the inverter injecting current into the grid? L H Insufficient input voltage Stop the inverter using start/stop

6 L.2 Process is the inverter displaying Vac=0V? is Vac out of limits? These grid voltage limits are imposed by the regulation Measure voltage on the inverter s AC input using a voltimeter class III is the inverter measuring AC voltage with a precision of 1%? Are AC protections switched on? Switch on AC protections 0002H/0004H/ 0006H Calibrate Vac and Iac scale ranges.trin# H/0004H/ 0006H Has been plugged the ac connector on the inverter? Plug AC connector on the inverter 0002H/0004H/ 0006H Measure voltage on the inverter s AC input using a voltimeter class III grid voltage Vac is available? 0002H Grid frequency out of range L H Grid voltage out of range 2000H Detection of island mode operation. 4000H Grid impedance out of range There is not grid

7 Process Act on the inverter Firmware Upgrade. Trin#15 have we solved the alarm? Replace Control Board. Trin#7 Calibrate Vac and Iac scale ranges. Trin#16 Alarms? Replace Power Board. Trin#8 0008H Over current in the inverter bridge. 0010H Over current in DC/DC converter. 0040H Grid overcurrent. 0100H Bus overvoltage. 0800H HW error. 1000H Instantaneous grid over current. 8000H Hardware fault alert.

8 L.4 Process 0420H Disconnect AC connector of the inverter Stop the inverter using start/stop Disconnect again the same dc input voltage of the inverter 0420H Reconnect the input dc disconnected in the past Repair terminals and wiring damaged in your installation or inverter Start the inverter using start/stop OUTPUT 3 Have you disconnected and reconnected all dc inputs of the inverter? 0420H OUTPUT H OUTPUT 2 Disconnect one DC input of the inverter 0420H are dc terminals dry and properly crimped? Reconnect the input dc disconnected in the past 0020H Insulation fault L.4 ( Part 1 ) You have to dry and crimp properly all terminals damaged

9 INPUT 1 INPUT 2 INPUT 3 Check the correct status of the ac connector on the inverter AC terminal dry and properly crimped? You have to dry and crimp properly this connector Plug AC connector of the inverter have been connected on the inverter all DC inputs coming from PV array? Check there is not earth fault on AC side and on DC side Stop the inverter using start/stop are all wiring and terminals ok in your installation and in your inverter? L.4 Repair all defaults found 0020H Insulation fault ( Part 2 ) Plug AC connector of the inverter have you check on detail all your installation and earth faults not found? 0420H Start the inverter using start/stop can the inverter connect with the grid? Start the inverter using start/stop Connect on the inverter all DC inputs coming from PV array 0400H You have to repair the input damaged in your installation on dc side

10 L.5 Process is it accompanied by the message comms!!! on the display? SeeTrin#12. External fans replacement Carry Out Trin#12 is orange led flashing? 0.5 second flash? See Trin#17. Display cable replacement Carry Out Trin#17 1 second flash? See Trin#13. Internal fan replacement Carry Out Trin#13 3 second flash? has the inverter external fan? is turning the external fan? Has the incidence been solved? L H Overtemperature Ensure that an adequate flow of air arrives. Heatsink must be free of dusty Persists the error for long period of time?

11 L.6 Process Please, wait the initial grid connection time is the inverter injecting current into the grid? L H Configuration Change

12 Firmware Upgrade. Trin#15 ( Only if it s necessary ) Procedure repair quote Ship the inverter to the customer Hardware Upgrade. ( Only if it s necessary ) After the inverter has been repaired: Test the inverter Check it works properly. Complete annex#3.
