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 
<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  
>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-
curring through the consumer. 
Try reconnecting the load.
Module current too 
high. 
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.
