Symptom
Possible Cause
Remarks / Remedy
Status LeD “PV” (2) is
Green - fast flashing
and there is no output
at the Load Terminals
battery over Voltage Discon-
nect Protection has been
activated due to high voltage
of ≥ 16V / 32V at the bat-
tery output terminals. Solar
Panel(s) and Load have been
disconnected
Disconnect the Solar panel(s) and discharge
the battery
Status LeD “bATT”
(3) is orange - Steady.
output is available at
the Load Terminals
battery Under Voltage
Warning Signaling has been
activated at ≤ 12V / ≤ 24V.
output is still available at
Load Terminals
Charge the battery. reduce / switch off load
to allow the battery voltage to rise
Will be reset automatically when voltage
rises to 12.2V / 24.4V and LeD will go back
to steady Green from steady orange
Status LeD “bATT” (3)
is red - Steady
No output voltage at
the Load Terminals
Protection against over
discharge of battery has been
activated at ≤ 11.1V / ≤ 22.2V
and the load has been discon-
nected.
Charge the battery. reduce / switch off load
to allow the battery voltage to rise:
- Load will be reconnected automatically
at 12.6V / 25.2V and the LeD will go back
to steady Green from steady red
Status LeD “Load” (7)
is red - flashing
Load has been disconnected
due to overload or short
circuit in the load circuit con-
nected to the Load Terminals:
- overload: 12.5A for 5 sec
- Short Circuit: 35A –
remove the cause of overload / short circuit:
- overload is reset manually by pressing
the “Set” button (8)
- first short circuit is reset automatically
after 10 sec. Second consecutive short
circuit will require manual reset by
pressing “Set” button (8)
Status LeDs “Sealed”
(6), “Gel” (5) and
“flooded” (4) are
flashing red
simultaneously
Input and output
circuits have been
disconnected
Heat sink of the
controller > 85°C
Check reasons for overheating. Improve
ventilation and ensure proper cool airflow
over heat sink surface
- Will reset automatically when the unit
cools down and temperature drops
to < 75°C
noteS:
• No leD indicator: measure battery voltage with multimeter. minimum 6v is required to
start up the controller.
• No Status leD indicator “Pv” (2) with normal connection: measure the input voltage of Pv
Panel(s), the input voltage must be higher than battery voltage!

Please note that in some applications like in Portable Solar Charging Kits, solar panel(s)
will be permanently connected to the input terminals of the Charge Controller and the
battery will be connected whenever the Portable Charging Kit is required to be used. In
these applications, the modules will start generating power as soon as these are exposed
to sunlight. However, there will be no power output from the Charge Controller until
the controller is connected to the battery.
