4.2 Alarm codes
As explained in chapter 3.3, the display can also show an error code in case of abnormal conditions
or faults. The table below shows all available error codes and the corresponding explanation.
Error code Explanation
E0 No error, normal operation
E1 Battery over discharge. The battery voltage has dropped below the
'Undervoltage Alarm Relay On Value'. The internal alarm relay will be
triggered as well. This error is released again once the battery voltage has
exceeded the 'Undervoltage Alarm Off Value'.
E2 Battery over voltage, charging disabled
E3 Battery over discharge. The battery voltage has dropped below the
'Undervoltage Alarm On Value'. This error is released again once the
battery voltage has exceeded the 'Undervoltage Alarm Off Value'.
E6 Solar charger overtemperature alarm. The charge controller is operating
too hot and will start decreasing the charge current. Or it will shut down
and restart when the temperature is within normal limits again.
E7 or E16 Battery over temperature. The Battery temperature sensor has detected a
too high battery temperature and stops charging. Once the temperature
falls back to normal levels again, charging will continue.
E8 PV input power overload. The solar charger remains to operate normally,
but current is now limited by the charger rather than the solar panels.
E10 PV input overvoltage. The solar panel voltage is higher than the maximum
allowed input voltage of the solar charger. Turn off the system immediately
to avoid permanent solar charger damage.
E15 Battery not connected while PV input power is provided. When a lead
based battery type is selected, the battery output voltage is zero. When a
Lithium based battery is selected, the battery output delivers a constant
voltage.
E19 Battery under temperature. The Battery temperature sensor has detected a
too low battery temperature and stops charging. Once the temperature
falls back to normal levels again, charging will continue.
