6. MANUAL EQUALISATION
To allow the charger to equalise the battery properly, use the manual equalise option only
during absorbtion and float periods, and when there is sufficient sunlight.
To enable equalisation, enter the setup-menu and press the "-" or "+" button until the text
"  " is visible on the menu. Press SELECT: the text "" will
blink, press SELECT again to start equalisation.
To terminate the equalisation mode prematurely, enter the setup-menu and press the "-" or
"+" button until the text "  " is visible on the menu. Press SELECT:
the text "" will blink, press SELECT again to stop equalisation.
Current and voltage limits are identical to the automatic equalise function (see section 4.3).
The equalise duration is however limited to max. 1h when triggered manually.
7. TROUBLESHOOTING
With the procedures below, most errors can be quickly identified. If an error cannot be
resolved, please refer to your Victron Energy supplier.

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
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.
Check if the right system voltage has been selected
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.
0
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.
