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 connector on the control-pcb (at
the left of the LCD) is properly connected.
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 50A. 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.
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.
