the correct polarity and the cro ection of the cable (refer
to connection plan on page 2).
• Never operate the controller without the battery “Main I”
connected. If the battery i not connected, the unit will not
deliver a defined output voltage.
• In ca e of wrong polarity of battery I, the internal afety fu e
will be relea ed. The replacement fu e hould have the
ame capacity, and it hould be of the ame type of
automobile fu e.
• Parallel charging of two or everal batterie of the ame
voltage (12v) i admi ible. The batterie are to be
“paralleled” in connection.
2. Solar Panel (mu t be connected):
• Shade the panel to minimize parking during connection
and to avoid damage due to eventual wrong polarity.
Ob erve the cable cro - ection (refer to connection
plan)!
• If everal mall olar panel are u ed, they are connected
in parallel (refer to connection plan). Partial hading of the
panel re ult in average higher capacity ( ee connection
plan).
3. Starter Battery START II (Option, can be connected):
• Connect the econd charging port to the econd battery
u ing the red connection cable (wire cro ection 1.5 -
2.5 mm²). Thi cable may be longer. In ca e of non-
utilization, thi terminal i left free.
• If u ed, the output for tarter battery II will be working with
reduced voltage and charging current rate . Thu , the main
olar power will be upplied to main battery being more
uitable.
• However, the vehicle tarter battery II will be kept in a
condition, that tarting will alway be po ible, even in ca e of
longer downtime and during winter operation.
• Connection of the negative pole „START II“ i not required, if
the negative pole „BOARD I“ i connected to the vehicle body.
Depending on the length of the cable, it may al o be
connected to the common negative connection of the olar
controller or to the negative pole of „BOARD I“.
4. Temperature Sen or (Optional, can be connected):

voltage to the battery temperature (temperature
compen ation).
• Mounting: the thermal contact of en or and battery "Main
I" (in ide temperature) hould be well. Thu , it hould be
crewed down to the negative pole or po itive pole of the
battery. It i al o po ible to fa ten it at the idewall
centre of the battery ca ing. En ure that the in tallation
place i not influenced by any ource of heat (motor block,
exhau t, heater etc.).
• Connection: Connect the temperature en or to the
terminal by mean of a 2-pole cable (cable cro ection
0.5 - 1.5 mm²). The polarity and cable length are of no
importance. The olar controller recognize the en or
automatically.
• Effect: The temperature-dependent charging voltage of
battery I will be adapted automatically to the battery
temperature. The temperature en or mea ure the battery
temperature. In ca e of low temperature (winter operation),
the charging voltage will be increa ed in order to improve
and accelerate full charging of the weak battery.

funktion
Enheten är en MPPT, eller maximal trömpunkt pårare, en
elektroni k DC till DC-omvandlare omoptimerarmatchningen
mellan olpanelerna ( olcell paneler) och batteriet. Detta
möjliggör hög pre tanda i kombination med en lätt vikt och må
dimen ioner. Tack vare den högkvalitativa elektroniken
fungerar den mycket effektivt. Den automati ka
laddning proce en bevarar enheten och överladdar inte
batterierna. Detta förlänger i in tur batterierna liv längd
av evärt. Den är lämplig för batterier med vät ka, gel eller
AGM-teknik och har en ut mpa laddning trömfördelning för
två eparata batterian lutningar.
Enheten kan kontinuerligt fungera och parallellläge.
Kon umenterna kan an luta , lå på eller koppla bort
kontinuerligt. Förbrukar medföljer och batterierna ladda
amtidigt via batteriet. Kon ument trömmen här bör vara
mindre än olcell laddning trömmen efter om batteriet
annar inte ladda .
Om enheten använd till amman med en extern
temperaturgivare för matning batteriet (batteri 1) reglerar
enheten laddning pänningen automati kt beroende på
batteriet temperatur. Detta äker täller är kilt effektiv och
kon am laddning av batteriet. Om en extern temperaturgivare
inte använd reglerar enheten laddning proce en ba erat på
den interna temperatur en orn.
Matning - och tartbatterierna kan ladda genom att an luta
en eller flera olmoduler. Ob ervera de maximala
pänning - och trömförbrukning värdena om ange på
tyrenheten omvända. Denna typ av an lutning bör
lutföra parallellt.
Laddningsprocess
Enheten har en elektroni k omvänd ingång pänning,
omvänd tröm och olkort lutning kydd.
Laddning trömmen läpp enda t ( e "laddning chema")

tröm tillgänglig från ollju . När en temperaturgivare
använd ker laddningen temperaturberoende.
Boost-fas

laddning lut pänningen har uppnått .
Flottörfas
Laddning pänningen är in tälld på 13,8v för GEL-typ, e
batteriladdning bord för andra typer. Laddning trömmen
junker till det värde om kräv för att
kompen erabatteriet jälvförbrukning. Ström leverera
fortfarande till kon umenterna via batteriet. Om den
förbrukade trömmen över krider den tillgängliga
olladdning trömmen kan laddning proce en inte längre
upprätthålla .
Om batteri pänningen junker under den valda
batterityp pänningenväxlar enheten automati kt till
boo tfa en, om det finn tillräcklig olladdning tröm.

Delvis urladdade batterier
(enda t för AGM- och flytande elektrolytbatterityp)
Till killnad från andra batterityper har blybatterier ingen
kadlig minne effekt. Följaktligen: I tvek amma fall må te
delvi urladdade batterier ladda fulladdade å nart om
möjligt.
Förvara alltid enda t fulladdade blybatterier. Ladda dem
regelbundet, är kilt vid använda (äldre) batterier och högre
temperaturer.
1. Flytande elektrolytbatterier kan kapa explo iva
ga er, å e till att det finn tillräcklig ventilation.
Kontrollera vät kenivån med jämna mellanrum.
Överladdning kan kada batteriet; kontrollera de
tekni ka uppgifterna för batteriet.
Vid otillräcklig olenergi och/eller hög trömförbrukning bör
batteriet ut ätta för tillfällig full laddning med hjälp av en
nätladdare.
Skydd mot överspänning
