WARNING #3
What This Code Means
One of the inverters has stopped working; Battery voltage begins to decrease below a given threshold; Battery is running low; System shutdown occurs (when State of Charge is less than 20%); High inversion close to the limits presented by the EHR; System increases its internal temperature; Temperature warning occurs; System worsens performance and increases inversion power; EHR equipment tries to synchronise with the grid and cannot do so; The mode of operation at that moment will be shut down immediately; Installation is supplied with a power higher than that which has been configured; Inverters heat up internally; Decrease in performance
Possible Causes
- •Worn RJ45 connector on the communication cables between the inverters and the L1 inverter to the Cerbo GX
- •Broken communication cable between the inverters and the L1 inverter to the Cerbo GX
- •Inverter is defective due to internal causes
- •Battery voltage drops below a given threshold
- •State of Charge (SoC) is less than 20%
- •High inversion power close to limits combined with high ambient temperature
- •High ambient temperature
- •Activation of the overload alarm
- •Connected phase sequence (either busbar or 'SOCKET') is invalid or not suitable
- •Maximum contracted power has been exceeded when the calendar is enabled and configured
- •Very high ambient temperature (above 30°C)
- •Very high inverter power (approaching inverter limits)
Suggested Actions
- 1Refer to section 7. Warning and alarms for more information
- 2Address the warning when it appears to prevent a temperature alarm from occurring, using the help functions shown on the screen
- 3Refer to section 7. Warning and alarms
- 4Refer to section 3.3. Technical characteristics for nominal inversion power values as a function of ambient temperature
- 5Configure the calendar (refer to Calendar section)
- 6Deal with the warning when it appears in order to prevent the temperature alarm from occurring as per the help functions shown on the screen
