Cause / Solution
The internal power supply used for powering the converter and the
backlight is derived from either the solar-array or the battery.
If PV and battery voltage are both below 6V the LCD will not light
up.
This may be due to low ambient temperature.
If the ambient temperature is below -10
segments can become vague.
0
Below -20 C (-4
During charging the LCD-display will warm up, and the screen will
become visible.
The LCD-display indicates that the charge-current is 0 Amps.
Check the polarity of the solar-panels.
Check the battery breaker
Check if there is an error indication on the LCD
Check if the charger is set to "ON" in the menu.
This error will auto-reset after temperature has dropped.
Reduced output current due to high temperature.
Check the ambient temperature and check for obstructions near
the air inlet and outlet holes of the charger cabinet.
This error will auto-reset after temperature has dropped.

C) This error can also be due to a bad/corroded battery- pole to which
this sensor is screwed on to, or a faulty sensor.
If error persists and charging does not resume, replace sensor,
and power-up by entering and leaving the setup menu..
This error will auto-reset after the battery voltage has dropped.
This error can be due to other charging equipment connected to
the battery or a fault in the charge controller.
Check if the T-sense connector is properly connected to a remote
temperature sensor.
This error will auto-reset after proper connection.
Check if the T-sense connector is properly connected to a remote
temperature sensor.
This error will auto-reset after proper connection.
This error will not auto-reset.
1. Press and hold the SETUP-button for 2 seconds to enter the
SETUP-MENU.
2. Set the charger from ON to OFF.
3. Scroll through the LCD-screens to find the battery temperature.
If the LCD indicates an unrealistic temperature value or "---"
replace
....the remote sensor.
4. Power-up by setting the charger from OFF to ON.
5. Check if the battery temperature is now valid.
This error will auto-reset after charger has cooled down.
Check the ambient temperature and check for obstructions near
