Problem
All LEDs flash 5 times in succession.
A buzzer sounds. After a short pause,
the process repeats.
The LED of the alternator and the solar
panel are lit continuously.
The alternator LED flashes 6 times.
An electronic malfunction has oc-
curred.
The voltage of the house battery ex-
ceeds 16 V.
The charge was interrupted.

Possible cause
The output connection fuses have
failed (GOLD25-M, GOLD30-M and
GOLD40-M only).
The solar panel voltage is too high.
The PCB is overheated.
The ambient temperature is below
– 2°C.
A voltage drop is detected at the alter-
nator.
The alternator has insufficient power.
A power failure on the cables has oc-
curred.
The voltage of the house battery is
higher than 15 V.
The desulfation phase takes place.
The starting battery is overcharged.
Suggested remedy
1. Ensure that the output connection
fuses (25 A) are not defective.
2. Ensure that the output connection
is securely connected.
Ensure that the solar panel voltage
is less than 28 V.
1. Let the battery charger cool down.
2. Restart the battery charger as soon
as the house battery is no longer
fully charged.
This is a normal protective mechanism
that is active when the charging curve
for flooded and LiFePo4 batteries is se-
lected (Configuring the battery charg
er on page 11). As soon as the am-
bient temperature rises above 0°C,
the LEDs switch off.
1. Ensure that the cables have a mini-
mum cross-section of 10 mm².
2. Ensure that cables with a length
of more than 2 m have a minimum
cross-section of 16 mm².
3. Ensure that the connections on
socket 1, 2, 3, and 6
on page 15/Fig.  on
page 15) are securely connect-
ed.
4. Ensure that the battery charger is
connected correctly.
Select the charging curve for flood-
ed and LiFePo4 batteries to avoid
the desulfation phase (see
figuring the battery charger
page 11).
This is a normal process that can take
up to 2 h.
1. Ensure a suitable battery type is
connected (see Intended use
page 8).
2. Ensure that the correct charg-
ing curve is selected (see
figuring the battery charger
page 11).
3. Ensure that the starting battery is
not overheated.
