Meaning
Cause / Remedy
Excessive tempera-
ture regulator turned
off the consumer
due to internal over
heating.
Let regulator cool. Check the
cause for overheating (installa-
tion site, other heat sources).
Possible reduce charge or load
current. Ensure the regulator
has proper ventilation.
No solar module
connected.

(Detection lasts ap-
prox. 15 minutes)
Check module connection.
Module connected with
reverse polarity, perhaps the
module feed wire is disrupted.
Battery voltage too
low.
Voltage <10.5 V or
Voltage <10.5 V or
<1.0 V
Check installation. Check bat-
tery voltage, possibly recharge
battery manually. Consumer
connected directly to the
battery can deep-discharge
the battery.
Battery voltage too
high.
Voltage >15.5V or
Voltage >15.5V or
>31 V.
Check installation. Check
battery voltage, possibly check
additional charge sources.
Load current too
high. The regulator’s
permitted consumer
current has been
exceeded, the load
output has therefore
been disconnected.
Reduce the load current using
the consumer output.
Perhaps current spikes are oc-
Perhaps current spikes are oc-
curring through the consumer.
Try reconnecting the load.
Try reconnecting the load.
Module current too
high.
The regulator’s per-
The regulator’s per-
mitted input current
has been exceeded.
Reduce the load current or
module power.
Short-circuiting at the
load output.
Remove short-circuit, dis-
connect consumer and try to
reconnect.
If there is a short
circuit in the module,
the moon symbol
appears during the
day.
The module input is protected
by an internal electronic fuse.
