6. Error Indications
With the procedures below, most errors can be quickly identified. If an error cannot be resolved, please refer to your Victron Energy supplier.
Our recommendation is to use the Victron Toolkit app to find the description of all possible LED alarm codes. See here for download information: https://www.victronenergy.com/support-and-downloads/software#victron-toolkit-app.
6.1. General error indications
Problem | Cause | Solution |
---|---|---|
No output voltage on AC-out-2. | Operating in inverter mode | Connect the inverter/charger to an AC source, and after a 2-minute delay, the AC-out-2 should become live. |
Unable to switch over to generator or mains operation. | Circuit breaker or fuse in the AC-in input is open as a result of overload. | Remove overload or short circuit on AC-out-1 or AC-out-2, and reset the fuse or circuit breaker. |
Inverter operation not initiated when switched on | The battery voltage is excessively high or too low. No voltage on DC connection. | Ensure that the battery voltage is within the correct range. |
‘Low battery’ LED flashes | The battery voltage is low. | Charge the battery or check the battery connections. |
Low battery’ LED lights. | The converter switches off because the battery voltage is too low. | Charge the battery or check the battery connections. |
‘Overload’ LED flashes. | The converter load is higher than the nominal load. | Reduce the load. |
‘Overload’ LED lights | The converter is switched off due to excessively high load. | Reduce the load. |
‘Temperature’ LED flashes or lights. | The environmental temperature is high, or the load is too high. | Install the converter in cool and well-ventilated environment, or reduce the load. |
‘Low battery’ and ‘overload’ LEDs flash intermittently. | Low battery voltage and excessively high load. | Charge the batteries, disconnect or reduce the load, or install higher capacity batteries. Fit shorter and/or thicker battery cables. |
‘Low battery’ and ‘overload’ LEDs flash simultaneously. | Ripple voltage on the DC connection exceeds 1.5 Vrms. | Check the battery cables and battery connections. Check whether battery capacity is sufficiently high, and increase this if necessary. |
‘Low battery’ and ‘overload’ LEDs light. | The inverter is switched off due to an excessively high ripple voltage on the input. | Install batteries with a larger capacity. Fit shorter and/or thicker battery cables, and reset the inverter (switch off, and then on again). |
One alarm LED lights and the second flashes. | The inverter is switched off due to alarm activation by the lighted LED. The flashing LED indicates that the inverter was about to switch off due to the related alarm. | Check this table for appropriate measures in regard to this alarm state. |
The charger does not operate. | The AC input voltage or frequency is not within the range set. | |
Circuit breaker or fuse in the AC-in input is open as a result of overload. | Remove overload or short circuit on AC-out-1 or AC-out-2, and reset fuse/breaker. | |
The battery fuse has blown. | Replace the battery fuse. | |
The distortion or the AC input voltage is too large (generally generator supply). | Turn the "Weak AC" and "Dynamic current limiter" settings on. | |
The charger does not operate. ‘Bulk’ LED flashes and ‘Mains on’ LED illuminates | Charger is in ‘Bulk protection’ mode thus, the maximum bulk charging time of 10 hours is exceeded. Such a long charging time could indicate a system error (e.g. a battery cell short-circuit). | Check your batteries. NoteYou can reset the error mode by switching the unit off and back on again. In the standard factory settings the ’Bulk protection’ mode is enabled. The ‘Bulk protection’ mode can be switched off with the help of VEConfigure only. |
The battery is not completely charged. | Charging current excessively high, causing premature absorption phase. | Set the charging current to a level between 0.1 and 0.2 times the battery capacity. |
Poor battery connection. | Check the battery connections. | |
The absorption voltage has been set to an incorrect level (too low). | Set the absorption voltage to the correct level. | |
The float voltage has been set to an incorrect level (too low). | Set the float voltage to the correct level. | |
The available charging time is too short to fully charge the battery. | Select a longer charging time or higher charging current. | |
The absorption time is too short. For adaptive charging this can be caused by an extremely high charging current with respect to battery capacity, so that bulk time is insufficient. | Reduce the charging current or select the ‘fixed’ charging characteristics. | |
The battery is overcharged. | The absorption voltage is set to an incorrect level (too high). | Set the absorption voltage to the correct level. |
The float voltage is set to an incorrect level (too high). | Set the float voltage to the correct level. | |
Poor battery condition. | Replace the battery. | |
The battery temperature is too high (due to poor ventilation, excessively high environmental temperature, or excessively high charging current). | Improve ventilation, install batteries in a cooler environment, reduce the charging current, and connect the temperature sensor. | |
The charging current drops to 0 as soon as the absorption phase initiates. | The battery is over-heated (>50°C) |
|
Defective battery temperature sensor | Disconnect the temperature sensor. If charging functions correctly after approximately 1 minute, the temperature sensor should be replaced. |
6.2. Special LED indications
For the normal LED indications, see the LED Indications chapter.
‘Mains on’ flashes and there is no output voltage | The device is in ‘charger only’ operation and mains supply is present. The device rejects the mains supply or is still synchronising. |
Bulk and absorption LEDs flash synchronously (simultaneously). | Voltage sense error. The voltage measured at the voltage sense connection deviates too much (more than 7V) from the voltage on the positive and negative connection of the device. There is probably a connection error. The device will remain in normal operation. |
Absorption and float LEDs flash synchronously (simultaneously). | The battery temperature, as measured, has an extremely unlikely value. The sensor is probably defective or has been incorrectly connected. The device will remain in normal operation. |
Note
If the "inverter on" LED flashes in phase opposition, this is a VE.Bus error code (see next chapters).
6.3. VE.Bus LED indications
Equipment included in a VE.Bus system (a parallel or 3-phase arrangement) can provide so-called VE.Bus LED indications. These LED indications can be subdivided into two groups: OK codes and error codes.
6.3.1. VE.Bus OK codes
If the internal status of a device is in order but the device cannot yet be started because one or more other devices in the system indicate an error status, the devices that are in order will indicate an OK code. This facilitates error tracing in a VE.Bus system, since devices not requiring attention are easily identified as such.
Important
OK codes will only be displayed if a device is not in inverter or charging operation!
A flashing ‘bulk’ LED indicates that the device can perform inverter operation.
A flashing ‘float’ LED indicates that the device can perform charging operation.
Note
In principle, all other LEDs must be off. If this is not the case, the code is not an OK code. However, the following exceptions apply:
The special LED indications above can occur together with the OK codes.
The ‘low battery’ LED can function together with the OK code that indicates that the device can charge.
6.3.2. VE.Bus error codes
A VE.Bus system can display various error codes. These codes are displayed with the “inverter on”, “bulk”, “absorption” and “float” LEDs.
To interpret a VE.Bus error code correctly, the following procedure should be followed:
The device should be in error (no AC output).
Is the ‘inverter on’ LED flashing? If not, then there is no VE.Bus error code.
If one or more of the LEDs ‘bulk’, ‘absorption’ or ‘float’ flashes, then this flash must be in phase opposition to the ‘inverter on’ LED, i.e. the flashing LEDs are off if the ‘inverter on’ LED is on, and vice versa. If this is not the case, then there is no VE.Bus error code.
Check the ‘bulk’ LED, and determine which of the three tables below should be used.
Select the correct column and row (depending on the ‘absorption’ and ‘float’ LEDs), and determine the error code. 6. Determine the meaning of the code in the tables below.
Determine the meaning of the code in the tables below.
All of the conditions below must be met!:
