Cause / Solution
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. Exit the SETUP-MENU.
4. Scroll through the LCD-screens to find the battery temperature.
If the LCD indicates an unrealistic temperature value or "---" replace
....the remote sensor.
5. Power-up by setting the charger from OFF to ON.
6. 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 the air inlet
and outlet holes of the charger cabinet.
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.
This error will auto-reset.
The internal battery current sensor indicates that current is flowing from the
battery to the solar array.
The charge controller is probably faulty.
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.
The charge controller is probably faulty.
This error will not auto-reset.
Disconnect all power-sources from the charger, and open the front cover.
Check if the white connectors on the control-pcb (at the left of the LCD) are
properly connected. The connector coming from the coil (mounted to the top
of the charger) should be connected in the right connector (CON302).
If connected properly, close front cover and power-up again.
If the error persists the charge controller is probably faulty.
This error will auto-reset.
This error will auto-reset after PV-voltage has dropped to safe limit.
This error is an indication that the PV-array configuration with regard to open-
circuit voltage is critical for this charger. Check configuration, and if required,
re-organise panels.
The current from the solar-panel array has exceeded 75A. This error could
be generated due to an internal system fault.
Disconnect the charger from all power-sources, wait 3 minutes, and power-
up again. If the error persists the controller is probably faulty.
This error will auto-reset.
Communication with one of the paralleled controllers was lost. To clear the
warning, switch the controller off and back on
The controller is being paralleled to another controller that has different
settings and/or a different charge algorithm.
Make sure all settings are the same and update firmware on all chargers to
the latest version
Connection to the BMS lost, check the CAN bus cabling. When the charger
needs to operate in stand-alone mode again, change to setup menu setting
'BMS' from 'Y' to 'N'.
This error will reset after the CPU has cooled down.
If the error persists, check the ambient temperature and check for
obstructions near the air inlet and outlet holes of the charger cabinet.
Check manual for mounting instructions with regard to cooling. If error
persists the controller is probably faulty.
