Using the pluggable LCD display or VictronConnect and the procedures
below, most errors can be quickly identified. If an error cannot be resolved,
please refer to your Victron Energy supplier.
Error nr. Problem
Cause / Solution
n. a.
The LCD does not light up
(no backlight, no display)
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. Make sure that the
LCD display is properly inserted into the
socket.
n. a.
The LCD does not light up
(backlight works, no display,
charger seems to work)
This may be due to low ambient temperature.
If the ambient temperature is below -10
0
C
(14
0
F) the LCD-segments can become vague.
Below -20
0
C (-4
0
F) the LCD-segments can
become invisible.
During charging the LCD-display will warm up,
and the screen will become visible.
n. a.
The charge controller does
not charge the battery
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 Remote input is connected.
Check if the right system voltage has been
selected
n. a.
High temperature: the
thermometer icon blinks
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 heatsink.
Err 2
Battery voltage too high
(>76,8V)
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.
Err 17
Controller overheated
despite reduced output
current
This error will auto-reset after charger has
cooled down.
Check the ambient temperature and check for
obstructions near the heatsink.
Err 18
Controller over-current
This error will auto-reset.
Disconnect the charge controller from all
power-sources, wait 3 minutes, and power up
again.
If the error persists the charge controller is
probably faulty.
Err 20
Maximum Bulk-time
exceeded
This error can only occur when the maximun
bulk-time protection is active. This error will not
auto-reset.
This error is generated when the battery-
absorption-voltage is not reached after 10
hours of charging.
For normal solar installations it is advised not
to use the maximum bulk-time protection.
Err 21
Current sensor issue
The charge controller is probably faulty.
