I have Solar connected but the Solar LED is OFF.
This indicates that the required turn ON conditions for this source have not been met. Either the
Open Circuit Voltage at the YELLOW wire on the charger is below 9 V or there is not sufficient power
available from the Solar Panel (due to poor light conditions or a faulty panel).
1.
Is the sun out? No or low sunlight levels mean low power to your solar panels.
2.
Check that the solar panel is not being shaded (by a tree etc.).
3.
Check the voltage at the YELLOW wire, as close as possible to the charger, is above 9 V.
4.
Check all wiring to the Solar Panel, particularly the Ground (BLACK wire).
5.
Ensure you have an unregulated solar panel.
Allow up to 2 minutes after any change for the unit to recognise the input, if the problem persists,
contact your local Auto-Electrician.
The BCDC is connected to the Vehicle but the Vehicle LED is OFF.
This indicates that the required turn ON conditions for this source have not been met OR the Solar
input is supplying the full input power requirements of the charger.
With the BLUE wire left unconnected, the voltage at the RED wire must be above 12.9 V for a 12 V
installation or above 25.8 V for a 24 V installation.
With the BLUE wire connected to Ignition, Ignition must be on and the voltage at the RED wire must
be above 12.0 V for a 12 V installation or above 24.0 V for a 24 V installation.
1.
Check that the vehicle is running.
2.
Check the voltage on the RED wire is above the required turn ON threshold for your installation
(see
"4.2 Turn On/Off Thresholds" (page 29)
3.
Check all wiring to the Vehicle battery, particularly the Ground wire (BLACK).
4.
Check connection to the auxiliary battery and auxiliary battery ground connection
If the problem persists, contact your local Auto-Electrician.
