The Inverter Charger Combi (ICC) is an all-in-one combination of a
DC to AC true sinewave inverter with AC Transfer switch and a AC input
power booster together with an advanced multi-stage battery charger.
All this is build into one compact, yet installer friendly enclosure. The
ICC is equipped with a Remote Control to operate the unit and display
the mode, power consumption and battery state with the help of
LED’s. Besides these main functions, there are several unique features
offered as well. Some of which benet from the strong interaction
between the main functions.
The Inverter Charger Combi is especially developed for usage in Recre-
ational Vehicles (RV).
The unit automatically starts charging the bord batteries and supplies
230V to all connected sockets when the vehicle is connected on shore
power.
For startup of heavy loads (e.g. aircondition), the AC input power boost
function will supply additional power from battery to avoid troubles
with weak exernal fusing.
In case of a grid/generator failure or disconnection, the Inverter
Charger Combi will turn off entirely in order to avoid uncontrolled
standby power consumption.
When there is no grid the inverter can be activated in either “Auto-
matic”- or “Permanent”-mode.
In case the grid/generator is reconnected again and the voltage and
frequency are within acceptable limits, the Inverter Charger Combi
activates the AC transfer switch and the battery charger again, while
deactivating the inverter. The connected loads are now supplied again
by the grid/generator without any interruption.
With the Remote Control the charger can optionally be operated in
night mode, noiseless without fans at half charge power.
Additionally, the Inverter Charger Combi offers features like:
•AC Input Power Boost, the inverter temporarily assists with pure
sinus synchronized to weak AC input sources when the connected
load needs more power than available from the grid or generator.
•AC Input Current Limit, which limits the maximum current
consumed from the AC input source by the Inverter Charger Combi.
This limitation is user selectable with a 3-way front panel switch for
A  A  A.
•Power Factor Corrected AC Input, which optimizes energy efficiency
and makes sure that the maximum amount of charging current at
actual consumption is available from your AC source.
•Intelligent 4-stage, temperature controlled charge programs, for
any lead- or lithium battery type using the standard supplied
battery temperature sensor for maximum battery lifetimes.
•Night mode charge program, with reduced fan speed at half charge
power.
•Automatic standby of the inverter when load <25W for 10 min.
•Low voltage protection, automatic switch-off at low battery voltage.
•Fully programmable inverter, transfer switch and battery charger
parameters, using the Dashboard for Windows soware.
•Programmable alarm relay, for optimal control of external devices
like generator starting or selective load disconnection.
•Freely assignable trigger input, which allows the user to control the
Inverter Charger Combi by external events.
•Temperature controlled fans, to guarantee silent operation under
less than full load conditions.

4.1 Operating the Inverter Charger Combi
The main switch of the unit needs to be supplied externally and
connected to the remote switch input (see installation guide). This
switch is recommended to combine with a switched output of the
vehicle board control which also turns on when then V main switch
in the RV is On.
Only then the inverter can be operated with its Remote Control.
4.1.1 Operation with shore power – 230V AC input available
The Inverter Charger Combi always turns on automatically – indepen-
dently of the remote switch position – when grid or a generator is
connected to the AC input. The Inverter Charger Combi will analyse
this signal. If the voltage and frequency of this signal are both within
the required limits, the Inverter Charger Combi will synchronize to the
input signal and activates the AC transfer switch automatically.
Connected V loads are powered from the AC input source and the
Inverter Charger Combi will also start charging the battery.
The AC input current limiter switch included in the frontpanel allows
limitation of the unit to the available grid power of either A, A or
max. A. In all settings the AC Input power boost is active and will
supply missing power up to the max. power available from the inver-
ter, if the connected loads exceed the available AC input power.
Optional “Night mode” when grid is available and the charger is active:
With remote control the charger can be operated in night mode. This
means that the maximum charge power will be reduced by 50% and
the fans are disabled and therefore noise reduced to a minimum.
As soon as the voltage or the frequency of the AC input signal are
exceeding the required limits (for example when the AC input signal
disappears), the Inverter Charger Combi will immediately stop
charging and power-off entirely.
4.1.2 No shore power – 230V AC input not available
For using the inverter the unit must be connected to the service
battery and a remote switch connected to the remote switch screw
terminal of the unit. (see also Installation manual)
The inverter only then can be switched On with the Remote control in
different modes, “Automatic”- or “Permanent”-mode. The Inverter
Charger Combi will perform all tasks automatically. It will power up in
inverter mode and supply power to the connected load.
Automatic mode:
The inverter is analysing the load on the output and will work
continuously if the output loads are bigger than W. Automatic mode
is visually indicated with a blinking inverter LED. Only if the load is
<25W for 10 min., the inverter will switch-off in standby.
Permanent mode:
The inverter will operate independent of the load. This mode is there-
fore recommended for small loads.
When the Remote Control is switched to Off, the Inverter Charger
Combi stays in standby-mode and can be reactivated by the Remote
Control.
When the V main switch is deactivated in the RV/your application,
e.g. the remote switch needs to switch off. The Inverter Charger Combi
then will power-off and draw no standby current from the battery.
Information about the LED indicators on the frontpanel and the
different error mode codes, can be found in the next chapter.
4.2 Fontpanel LED indicators and error modes

“I” - position = A @V
“0” - position = max. current please see Cha. 
“II” - position = A @230V
See chapter . for more explanations.
4.2.1 Error indications
When the so called mode indicator LEDs are blinking red, an error has
been detected. Each mode indicator LED can either blink red individu-
ally, or combined along with one or more other mode indicator LEDs.
There are ve different error indications, each with their own blinking
pattern:
One ash in a row: Battery related error (too low or too high battery
voltage, too low or too high battery temperature, too high battery
ripple voltage, battery defect)
Two ashes in a row: AC overload error (AC load requires too much
power from the inverter, AC output short circuit)
Three ashes in a row: High temperature error (Inverter Charger Combi
shuts down on high temperature)
Four ashes in a row: Device error (an error has occurred inside the
Powersine Combi. Please return for service)
Five ashes in a row: Charge program error (only for “charger on”
indicator LED).
Charge program selection set to Custom, while custom made charge
program contains an error or time-out.
The Inverter Charger Combi will mostly recover from an error mode
automatically when the cause of the error has been resolved.
However, when an error has occurred due to a high battery ripple
voltage or an AC transfer switch overcurrent, the Inverter Charger
Combi needs to be switched off and on again manually (manual
restart). The Inverter Charger Combi also needs to be restarted
manually, when too many battery or overload errors have occurred
within a short period of time.

The remote control displays synchronous to the frontpanel of the ICC
unit. Please see .. Frontpanel LED indicators and error modes for
more details.
Note: The “AC in”-LED corresponds to “Line” of the ICC frontpanel.
On-/Off-/mode button:
This button offers 2 different inverter modes when no grid is available:
- short push: Turns the inverter On in “Automatic” mode.
- s push: This changes (only aer inverter is On) in “Permanent”
mode, indicated by a slow blinking inverter LED.
Another short push turns the inverter and LED’s off.
Night mode when grid is available and the charger is active: A s push
will force the charger into night mode and the LED brightness dimmed
followed by 2 beeps for acoustical conrmation. This means that the
maximum charge power will be reduced by % and the fans are
disabled and therefore noise reduced to a minimum.
The charger will automatically exit night mode aer  hrs., jump back
to charge power, enable fans again and set full brightness on the LED’s.
Night mode can also manually interrupted, or the ICC switched off
(put into standby) by a short push.

4.4 Advanced options
4.4.1 Programmable Alarm relay
The Inverter Charger Combi is equipped with one or two (depending
on model) programmable potential free alarm relays. Standard, this
relay (or relay on ICC  SIN/A model) will be activated when
the unit shuts down and jumps to an error mode. The alarm relay
de-activates again when the error has been resolved and the Inverter
Charger Combi is running in normal operating mode again.
Relay on the ICC  SIN/A model will be activated only aer
the AC supply has become available. In case of battery operation, Relay
will deactivate immediately. This can be used to switch less critical
AC loads (i.e. electric boiler, aircon) on and off that are allowed to be
supplied by the mains or generator only.
Using Dashboard soware, it is also possible to congure the pro-
grammable relays to perform a different task, like starting a generator
when the battery voltage has reached a certain low voltage level.
Both normally closed and normally open contacts of these relays are
available. For the ICC  SIN/A model, the maximum relay contact
ratings are VDC/A or VDC/.A. For the ICC  SIN/A model,
the maximum relay contact ratings are Vdc/A or Vac/A.
4.4.2 Trigger input
The trigger input offers a way of externally controlling the behaviour
of the Inverter Charger Combi. The trigger input can be connected to
an external switch or a potential free relay contact. By closing this
external switch or contact, a user programmable “action” will be
performed. Such an action could for example be to release the
AC transfer switch, temporarily disable the AC input Power Boost
feature or force the Inverter Charger Combi to switch to inverter mode.
All this can be congured. The ICC 1600 model is equipped with one
trigger input, while the ICC 3000 models is equipped with two trigger
inputs.
4.5 Load requirements in inverter mode
Before you connect your appliance(s) to the Inverter Charger Combi AC
output, always check it’s maximum power consumption. Do not
connect appliances to the AC output requiring more than the nominal
power rating of the inverter continuously. Unless these appliances are
switched on only when the AC transfer switch is activated, and power
is drawn from an external source with a larger capacity than the inverter.
Some appliances like motors or pumps, draw large inrush currents at
startup. It is possible that the startup current exceeds the overcurrent
trip level of the inverter. In this case the output voltage will shortly
decrease to limit the output current of the inverter. If the overcurrent
trip level is continuously exceeded, the inverter will shut down and
automatically restart within  seconds. In this case it is advisable to
disconnect this appliance from the inverter, since it requires too much
power to be driven by this unit. The Inverter Charger Combi needs to
be restarted manually when it has shut down due to overloads for four
times in a row. Note that at higher ambient temperature levels, the
overload capacity of the Inverter Charger Combi will be reduced.
5. Charger operation
5.1 Charge programs
All standard selectable charge programs (using DIP switches ,  and ),
perform a four stage IUoUoP charging process comprising of a “Bulk”,
an “Absorption”, a “Float” and a “Pulse” stage. The image below
visualizes the four stage charging process:
In the Bulk stage, the charger delivers full output current and typically
returns approximately % of charge back into the battery once the
absorption voltage is reached. During this stage, the battery empty
and battery % full indicators will be lit depending on the Bulk
charge progress. When the absorption voltage has been reached, the
Absorption stage will be entered and the battery % full indicator
will be lit. This stage will return the nal % of charge to the battery.
The output voltage is kept at a constant level and the charge current
decreases as a function of the battery’s state of charge. When the
charge current has dropped below a certain value or when the
maximum absorption timer has been expired, the Float stage will be
entered. The battery full Indicator will be lit and an acoustical message
will sound, indicating that the battery is full. In this stage the battery
voltage will be held constant at a safe level for the battery. It will
maintain the battery in optimal condition for as long as the battery
remains connected to the activated charger. Connected battery loads
will be directly powered by the charger up to the charger’s maximum
output current level. When even more current is drawn, the battery
must supply this which results in a declining battery voltage. At a
certain battery voltage level, the charger jumps back to the Bulk stage
and will nalize a complete charging process again, once the battery
load consumption has dropped below the charger’s maximum output
current level.
The fourth stage called “Pulse”, will perform a short refresh charge of
approximately hour each days while the charger operates in the
Float stage.


EN
This will keep the battery in optimal condition while
prolonging it’s lifetime. The battery can remain connected to the
activated charger continuously, without risk of overcharging.
The battery temperature sensor always needs to be installed. The
charger automatically compensates the charge voltages against
battery temperature for all types of lead batteries. Charge voltages are
slightly increased at lower temperatures and decreased at higher
temperatures (-mV/ °C from  °C). For LiFePo charge programs no
temperature compensation in charge voltage is applied, but a charge
current reduction down to % of the maximum charge current
at battery temperatures below °C.
This way, overcharging is prevented which prolongs your battery’s
lifetime.
When the standard selectable charging programs do not satisfy your
requirements, or when different voltage- and current levels are
needed, you can edit or create your own charge programs using
Dashboard soware. Up to different stages can be linked together
and all individual stages can be congured extensively.
5.2 Equalizing a flooded battery
If you are using a ooded lead acid battery, an occasional equalization
charge cycle may be recommended by the manufacturer. This might
also be true when the ooded battery has been very deeply dischar-
ged or oen charged inadequately. During equalization, the battery
will be charged up to .V (!) at a reduced output current level.
Before starting an equalization charge cycle, the following caution
statements must be read carefully:

Caution
Equalization should only be performed on a flooded (wet) lead acid
battery. Therefore the Inverter Charger Combi only allows equalization
when the battery type DIP switches are set to Flooded. Other battery
types like GEL or AGM will be damaged by this process.
Always follow the battery manufacturer’s instructions when equali-
zing flooded batteries.
During equalization, the battery generates explosive gasses. Follow
all the battery safety precautions enclosed with your Inverter
Charger Combi. Ventilate the area around the battery sufficiently and
ensure that there are no sources of flames or sparks in the vicinity.
IMPORTANT: Disconnect all loads connected to the battery during
equalization. The voltage applied to the battery during this process
may be above safe levels for some loads.
The Inverter Charger Combi cannot automatically determine when to
stop the equalization of a battery. The user must monitor the
battery’s specific gravity throughout this process to determine the
end of the equalization cycle. The internal 2 hours time-out timer of
your charger is only intended as a safety feature, but may not be
sufficiently short to prevent battery damage. Therefore, equalizing a
battery is always a process that must continuously be supervised by
the user.
Since equalization is only allowed for ooded (wet-) lead acid batteries,
the Inverter Charger Combi will only allow this function to be available
when the „Flooded“ charging program is selected (see chapter .).
Besides this, the charger also needs to have a full charge cycle completed
and must operate in the Float stage. When these two conditions are
met, the equalization charge mode can be activated by pressing the
recessed pushbutton on the bottom side of the unit (see images be-
low) for  seconds, until all charge status indicators start ashing.
Models: ICC  SIN/A:
Models: ICC  SIN/A:
The Inverter Charger Combi will allow a maximum equalization time
of hours before it automatically jumps back to the Float stage. If the
specic gravity of each cell does not match the battery manufacturer’s
specications yet, you can initiate a new hours equalization cycle by
pressing the pushbutton for seconds again. Always keep on checking
the specic gravity of each cell repeatedly during the equalization
process. When these values are correct, you can manually exit the
equalization process by pressing the recessed pushbutton once. The
Inverter Charger Combi will then return to the Float stage.

Caution
When configuring the Inverter Charger Combi by the Dashboard-SW,
make sure that DIP switch 1 is set to ON (External). When set to ON,
all remaining DIP switch settings (2 up to 7 or 9) are ignored and the
Inverter Charger Combi will always load the parameter settings as
configured in the Dashboard.
When DIP switch 1 is set to OFF (Local) again, DIP switch 2 up to 7 or
9 are overriding the corresponding parameter settings previously
made in Dashboard. The parameters that cannot be configured by
DIP switches, shall return to the factory default settings.


EN
The table below shows an overview of the most relevant factory
parameter settings, as stored in the Inverter Charger Combi. These
settings are optimized for application in a RV.
Parameter Inverter frequency
Value Hz
Description Output frequency in inverter mode. Can be set to Hz or Hz
Parameter Inverter frequency
Value V
Description Output voltage in inverter mode. Can be set from V to V
Parameter Low Battery Protect
Default Value On
Description Enables or disables low battery protection with user programmable shutdown, restart and delay values
(standard respectively V, V and  seconds). Turning Low Battery Protect off, results in immediate
inverter shutdown when the battery voltage is less than .V
Congurable by DIP switch (DIP ) and Dashboard
Parameter Automatic Stand By (ASB)
Default Value Off
Description Enables or disables ASB. If enabled, the inverter will jump to ASB mode automatically, when the
connected load power consumption drops below a user programmable level. In ASB mode the inverter
pulses it’s output sinewave in order to detect when the connected load requires more power again.
While running in ASB mode, the Inverter Charger Combi itself draws signicantly less current from the
battery. As soon as the load power demand increases again, the inverter will automatically jump to
continuous mode delivering uninterrupted power to the load. When disabled, the inverter will always
run in continuous mode, which is better for critical loads like computers, clocks and AV equipment.
Parameter AC input voltage range (transfer switch)
Default Value V  V
Description Input voltage range which is accepted by the Inverter Charger Combi for feeding through to the
connected load. Two AC undervoltage values can be set. An absolute undervoltage level which directly
releases the AC transfer switch when exceeded (factory setting = V), and a delayed undervoltage level,
which releases the AC transfer switch aer a certain delay (factory settings are V and  seconds).
The charger stops charging when the AC input voltage drops below V and restarts again above V.
Parameter AC input frequency range
Default Value Hz–Hz
Description Input frequency range which is accepted by the Inverter Charger Combi. Can be set to full range
(Hz–Hz), or to a smaller range within the Hz lower and Hz upper boundaries.
Parameter AC Input Current Limit
Default Value .A ICC  SIN/A/ .A ICC  SIN/A
Description Represents the maximum continuous current that the Inverter Charger Combi will draw from the AC
input source. To assure this, the Inverter Charger Combi will either reduce the charge current automati-
cally, or will activate the AC Input Power Boost feature which will supply the additional power demand
by running the inverter in parallel with the AC input source. When the connected load still draws too
much current, the installer can either choose to deactivate the AC transfer switch, or keep it closed and
allow it to exceed the AC input current limit value. The limit is selectable with the frontpanel switch
to xed values of A, A and A/A. This value can also be set from .A to .A or .A to .A
(depending on model) to a xed value by Dashboard.


EN
Parameter AC Input Power Boost
Default Value Off
Description AC Input Power Boost temporarily assists weak AC input sources when the connected load needs more
power than available from the grid or generator. This is accomplished by running the inverter in parallel
with the AC input source. The inverter can add power up to it’s nominal output power rating assuming
the battery is healthy. This parameter can be set On or Off.
Congurable by DIP switch (DIP ) and Dashboard
Parameter Ground switch
Default Value Enabled
Description The ground switch is an internal relay that automatically connects AC output Neutral (N) to Protective
Earth (PE = chassis) in inverter mode. This enables the use of a ground fault circuit interrupter (GFCI) at
the AC output of the Inverter Charger Combi. When a non-grounded (oating-) output is required, this
Parameter can be disabled.
Parameter AC input fail sensitivity
Default Value Normal
Description This parameter can be set to Very Low, Low, Normal, High and Very High. The value of this Parameter
decides how fast the Inverter Charger Combi detects a signal fail at the AC input. The lower settings are
resulting in a slower AC input source → inverter transfer time, while the higher settings result in the
fastest transfer times. The settings Low and Very Low can be used when the AC input signal is distorted
or unstable, which could be the case when a small generator is used. The settings High and Very High
can be used when the Inverter Charger Combi is connected to a solid grid or quality generator. The
factory setting Normal is a good compromise, which still results in a fast AC input source → inverter
transfer time of less than 5ms, while being reasonably immune against distorted AC input signals.
Parameter Battery type/Charge program
Default Value Liquid-acid
Description The default charge program liquid-acid is compatible with typical ooded type batteries, but can be
used for other types of lead-acid batteries as well. Please make sure that you always check if the
Inverter Charger Combi charge program settings, are compatible with the used battery! The AGM charge
program absorption voltage is .V and the oat voltage is .V . Other selectable charge programs
are GEL, AGM1, AGM, and  different types of LiFePo batteries. For further charge program information,

Parameter Charge current limit
Default Value %
Description This parameter sets the maximum charge current in percent. This value can be set with DIP switch(es) or
by Dashboard (from % to %). You should set this parameter to a lower value when the connected
battery is too small and cannot handle the maximum charge current, or when you wish to (temporarily)
reduce the charger current share, in the total amount of current owing through the AC input of the
Inverter Charger Combi.

. Dieses Gerät ist zum Auaden von BLEIBATTERIEN (Nass, GEL,
AGM) geeignet, und um Verbraucher zu versorgen, die mit solchen
Batterien in festen Installation zu tun haben. Dieses Gerät ist auch in
der Lage, bestimmte Lithium-Akkus (LiFePo) aufzuladen. Unterneh-
men Sie mit diesem Gerät keine Versuche, Batterien mit anderer
chemischer Zusammensetzung oder nicht-wiederauadbare Bat-
terien aufzuladen. Dies kann zur Explosion der Batterie führen
und folglich Körperverletzungen oder andere Schäden verursachen.
. Installieren Sie eine externe Sicherung (DC) oder einen Lasttrenn-
schalter der richtigen Größe so nah wie möglich an den Batterie-
polen.
. Um die Gefahr einer Explosion der Batterie zu vermeiden, folgen
Sie diesen Anleitungen und denen, die vom Hersteller der Batterie
oder aller anderen Geräte, die Sie in der Umgebung der Batterie

Betriebshinweise:
•„Netz“-Signalausgang:
An dieser Klemme wird ein 12V Signal geliefert sobald der BCB am Netz angeschlossen ist. Es kann
zu Steuerungs-und Anzeigezwecken genutzt werden. Der Ausgang kann bis zu 0,1A liefern und ist
gegen Kurzschluss und Überlastung geschützt.
•Ladevorgang unterbrechen:
Der Ladevorgang im Booster-Betrieb wird nach einem Stillstandder Lichtmachine bzw. Entfernen des
Steuersignals „D+“ unterbrochen. Ebenfalls bei Netzbetrieb nach Ausfall der Netzversorgung.
Die angeschlossenen Batterien werden nicht vom BCB entladen. Der Ladevorgang kann auf diese
Weise jederzeit unterbrochen werden.
Bei häufigen Unterbrechungen, speziell vor dem Erreichen der Vollladung (LED „Battery Full“ leuchtet
dauernd), sollte der Batterie jedoch im Netz-Betrieb gelegentlich ein vollständiger Ladezyklus
von
24 Stunden zur Ausgleichsladung gegönnt werden.
•Batterielebensdauer: Teilentladene Batterien:
Batterien auf Blei-Basis besitzen im Gegensatz zu anderen Batterie-Technologien keinen
schädlichen Memory-Effekt. Daher: Im Zweifel teilentladene Batterien möglichst bald wieder voll
laden.
Nur vollgeladene Batterien lagern, regelmäßig nachladen, besonders bei gebrauchten (älteren)
Batterien und bei höheren Temperaturen.
•Batterielebensdauer: Tiefentladene Batterien sofort laden:
Einsetzende Sulfatierung der Batterieplatten bei Tiefentladungen durch sofortige Ladung
unterbinden, insbesondere bei niedrigen und hohen Umgebungstemperaturen. Fallsdie Sulfatierung
noch nicht zu weit fortgeschritten war, kann die Batterie einen Teil der Kapazität nach einigen Lade-
/Entladezyklen wieder zurückerlangen.
•Batterielebensdauer: Batterien kühl halten, Einbauort entsprechend auswählen.
•Überspannungsschutz der START-Batterie:
Der BCB schütztsich auf der START-Seite gegen den Anschluss zu hoher Spannungen,
Schaltschwelle 16,5 V, automatische Rückkehr < 16,5 V.
•Überspannungsschutz der BORD-Batterie:
Der BCB schütztsich auf der BORD-Seite gegen den Anschluss zu hoher Batteriespannungen bzw.
schaltet bei defekten zusätzlichen Ladeanlagen (Solaranlagen, Generatoren o. ä.) ab, Schaltschwelle
15,5 V, Verzögerung 20 s. Rücksetzung durch Batterie < 12,75 V (30 s),entfernen des Steuersignal
„D+/Kl.15“, Netzstecker ziehen.
•Überspannungsbegrenzung BORD-Batterie:
Zum Schutz empfindlicher Verbraucher ist die Ladespannung auf max. 15,0 V bei allen Ladearten
begrenzt.
•Überlast- / Überhitzungsschutz BCB:
Der BCB ist gegen Überlastung doppelt elektronisch gesichert und schützt sich selbst gegen widrige
Einbaubedingungen (z. B. schlechte Belüftung, zu hohe Umgebungstemperaturen) durch allmähliche
Abregelung der Ladeleistung.
Batterielebensdauer:
•Batterien kühl halten, Einbauort entsprechend auswählen.
•Offene Säurebatterien („wartungsfrei nach EN / DIN“): Regelmäßig Säurestand
prüfen!
•Tiefentladene Batterien sofort wieder aufladen, teilentladene Batterien gegen
einsetzende Sulfatierung möglichst bald wieder voll laden!
•Nur vollgeladene Batterien lagern und regelmäßig nachladen, besonders ältere,
gebrauchte Batterien bei höheren Temperaturen!Falls eine Sulfatierung noch nicht zu
weit fortgeschritten war, kann die Batterie einen Teil der Kapazität nach einigen Lade-
/Entladezyklen wieder zurückerlangen.
