E01
CH3 High Input Voltage Shutdown
This means the unit has detected the input from the Start/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
This means the unit has detected that the input from the Start/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 above 13.2V on a 12V input or 26.4V on a 24V input.
• Check that you have not left the “Priority” (Override) feature activated (Manual or Auto)
• Check that the battery cable from the Start Battery is correctly sized.
• Check you don’t have a loose terminal or blown fuse.
E03
CH2 High Input Voltage Shutdown
This means the unit has detected 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 specication 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
This means the unit has detected the input from the Solar Array cannot sustain voltage above 14.5v.
If you have this error:
• Check that you are not in a low light/non direct sunlight situation i.e. Early morning / late afternoon.
• This may also happen if your solar panels are inside in a shed with a skylight or Hi Bay Lights running or outside under
Flood Lights.
If you nd this is happening with your unit when stored, we recommend tting a DC Breaker to the output of the DC2DC+
and turning it o when the unit is not in use/storage.
E05
CH1 High Input Voltage Shutdown
This means the unit has detected that the Main/House battery has gone above 16.0V. This error will clear once the input
has dropped below 15.5V.
This may be due to charging from another source. i.e. Another solar controller or AC battery charger.
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.
• Check to make sure the fan is working.
• Make sure the unit has good ventilation.
E07
BTS Over Temperature Shutdown
This means the units Battery Temp 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 bad temp sensor. Unplug the temp sensor and
call Enerdrive.
