Codes will show on the DC2DC display when a warning is triggered or a fault occurs. Depending on the warning or fault encountered, the DC2DC may shutdown to protect itself until the fault has cleared. See table below for more information on the DC2DC fault codes and how they might be cleared:
Code |
Description
|
E01 |
CH3 High Input Voltage Shutdown The input from the start battery/alternator has gone above 16.0V on a 12V input or 32.0V on a 24V input. This error will clear once the input has dropped below 15.5V on a 12V input or 31.0V on a 24V input. |
E02 |
CH3 Low Input Voltage Shutdown The input from the start battery/alternator has gone below 10.5V on a 12V input or 21.0V on a 24V input. This error will clear once the input has risen above 13.2V on a 12V input or 26.4V on a 24V input.
If you have this error:
- Check that the voltage of your start battery is within a healthy range both while the vehicle is off and while it is running.
- Check that you have not left the “Priority” feature activated. More information about "Priority" mode can be found here.
- Check that the battery cable from the start battery is correctly sized. More information about cable sizing can be found here.
- Check you don’t have a loose terminal or blown fuse.
|
E03 |
CH2 High Input Voltage Shutdown The input from the solar has gone above 45.0V. This error will clear once the input has dropped below 44.0V.
If you have this error:
- Check the specification of your panels – the Volts Open Circuit (VOC) should not exceed 45VOC
- Make sure the solar panels have not been connected in series as this will increase the VOC voltage of the panel array.
- Please Note: Maximum solar VOC input must not exceed 45VOC or damage to the unit will occur.
|
E04 |
CH2 Low Input Voltage Shutdown The input from the solar array cannot sustain voltage above 14.5V.
If you have this error:
- Make sure your solar panels are connected directly to the DC2DC and not going through a separate solar regulator or controller first.
- Check that you are not in a low light/non direct sunlight situation (e.g. early/late in the day, parked under shade or clouds).
- This may occur if your solar panels are inside in a shed with a skylight, high bay lights, or outside under flood lights.
- If you find this is happening with your unit when stored, we recommend fitting a solar isolation switch to disconnect the panels while the unit is in long term storage.
|
E05 |
CH1 High Input Voltage Shutdown The auxiliary battery has gone above 16.0V. This error will clear once the input has dropped below 15.5V.
If you have this error:
- Check your voltage of your auxiliary battery.
- Check other charging sources (e.g. another solar controller or AC battery charger) to ensure they are not charging your auxiliary battery at too high of a voltage.
- Make sure you do not have unregulated solar panels connected to the battery without going through the DC2DC or another solar controller
|
E06 |
Over Temperature Shutdown When the charger senses the environmental temperature above 60°C, the charger will shut down. It will recover automatically when the environmental temperature drops below 45°C.
If you have this error:
- Disable "Auto" (Silent) mode
- Check to make sure the fan is working.
- Make sure the unit has good ventilation and is out of direct sunlight
|
E07 |
Battery Temperature Sensor Over Temperature Shutdown The battery temperature sensor has detected that the batteries are too hot and has shut down to not over charge the batteries. If this occurs, take care and check the temperature of the batteries.
- If the batteries are hot, you may have a dropped cell or faulty battery. Stop all charging and see your local battery shop to get your batteries tested.
- If the batteries/terminals are still cool or only warm, you may have a faulty temperature sensor. Unplug the temperature sensor and call Enerdrive
|
E08 |
H1 Output Short Circuit This means there is a short circuit on the DC output to your auxiliary battery. If this is displayed, check the following:
- The output wires are not shorted together.
- The output wires are connected correctly and not reversed polarity
|
A01 |
Over Temperature Warning When the charger’s internal temperature is > 60°C, the unit will shut down to protect itself. The unit will return back to normal charging once the internal temperature is <58°C
If you have this error:
- Disable "Auto" (Silent) mode
- Check to make sure the fan is working.
- Make sure the unit has good ventilation and is out of direct sunlight
|
A02 |
Battery Temperature Sensor High Temperature Warning When the battery temperature sensor is >58°C, the unit will shut down to protect the batteries. The unit will return back to normal charging once the battery temperature sensor is <56°C.
If you have this error:
- Disable "Auto" (Silent) mode
- Check to make sure the fan is working.
- Make sure the unit has good ventilation and is out of direct sunlight
