Introduction
General
• Multi-functional Feature
The “Combi-Gamma” is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC Auto Transfer Switch
(ATS) in a single compact enclosure. Besides these primary functions, however, the
Combi-Gamma has several advanced features that provide a range of new applications
as outlined below:
• Uninterrupted AC Power
In the event of a grid failure, or shore or generator power being disconnected, the inverter within the Combi-Gamma is automatically activated and takes over supply to the
connected loads. This happens so fast (less than 10 milliseconds) that computers and
other electronic equipment will continue to operate without disruption.
• Parallel Operation
Virtually unlimited power thanks to parallel operation up to 5 units can operate in parallel
to achieve higher power output. Five COMBI3024 units, for example, provide 15kW of
output power with 350A charging capacity.
• Three Phase Capability
In addition to parallel connection, three units of the same model can be configured for
three-phase output. But that’s not all: up to five sets of three units can be parallel connected for a huge 45kW inverter and 1050A charger!
• Power Control-Dealing with limited generator or shore connection
The “Combi-Gamma” is a very powerful battery charger. It will therefore draw a lot of
current from the generator or shore connection. A maximum generator or shore current
can be set (B2-05). The “Combi-Gamma” will then take account of other AC loads and
use whatever is extra for charging thus preventing the generator or shore supply from
overload.
• Load Support-boosting the capacity of shore or generator power
This feature takes the principle of Power Control to a further dimension allowing the
“Combi-Gamma” to supplement the capacity of the alternative source. Where peak
power is so often required only for a limited period; it is possible to reduce the size of
generator needed or conversely enable more to be achieved from typically limited shore
connection. When the load reduces, the spare power is used to recharge the battery.
Battery Charger
• Adaptive 4-stage charge characteristic: Bulk-Absorption-Float-Equalize
The “Combi-Gamma” features a microprocessor controlled “adaptive” battery management system that can be preset to suit different types of batteries. The “adaptive” feature
will automatically optimize the process relative to the way the battery is being used.
• The right amount of charge: Variable Absorption Time
When only shallow discharges occur (a yacht connected to shore power for example),
the absorption time is kept in order to prevent overcharging of the battery. After a deep
discharge, the absorption time is automatically increased to make sure that the battery
4 090138.02
Battery charger / inverter COMBI-GAMMA
is completely recharged.
• Preventing damage due to excessive gassing: The Battery Safe Mode
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen. The “Combi-Gamma” will prevent damage due to
excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached.
• Less maintenance and aging when the battery is not in use: The Equalize Mode
The equalize mode kicks in whenever the battery has not been subjected to discharge
during 24 hours. In the equalize mode, float voltage is reduced to 2.2V/cell (13.2V for
12V battery) to minimize gassing and corrosion of the positive plate. Once a week, the
voltage is raised back to absorption level to “equalize” the battery. This feature prevents
stratification of the electrolyte and sulphation, a major cause of early battery failure.
• 2 outputs to charge 2 battery banks
The “Combi-Gamma” features 2 outputs, of which 1 can carry the full output current.
The second output, limited to approximately 4A and with a slightly lower output voltage,
is intended to top up a starter battery.
• To increase battery life: Temperature Compensation
Every “Combi-Gamma” can be equipped with a battery temperature sensor (BTS-3)
when connected, charge voltage will automatically decrease with increasing battery
temperature. This feature is especially recommended for sealed batteries and/or when
important fluctuation of battery temperature is expected.
• Battery Voltage Sense
In order to compensate for voltage loss due to cable resistance, the “Combi-Gamma”
is provided with a voltage sense facility so that the battery always receives the correct
charge voltage.
• Extensional Solar Charger
Combi-Gamma also provides the availability of up to 10 sets of Solar Charger, SunStar-45 or SunStar-60 (optional) to be used with solar panel to charge the battery. Combi-Gamma sends the 4-stage charging command to extensional Solar Charger via port
C (Extension Port) for the best quality of solar charging.

NOTE
Chapter 6 Programming Constants
A Group (Initialize):
A1 Group (Initialize)
A1-01: Access level
• Use constant A1-01 to select the user constant access level.
This level determines which user constants can be changed and displayed.
Setting
A1-01=0
A1-01=1
(Initial setting)
Function
This setting allows the “operation” and “initialize” to be changed or displayed.
Use this setting to prevent user constant settings from being changed.
This setting allows all user constants to be changed or displayed.
A1-02: Select Language
• Use constant A1-02 to select the language displayed by the Combi-Gamma. A value of
0 set English and values of others set other language.
• This user constant is not returned to factory setting when constants are initialized. It
must be manually reset to factory setting.
Setting
A1-02=0
(Initial setting)
Function
English language
A1-02=1
Reserved, under development
A1-02=2

A1-02=3
Reserved, under development
A1-02=4
Reserved, under development
A1-02=5
Reserved, under development
A1-02=6
Reserved, under development
A1-03: Init Parameters
• Use constant A1-03 to initialize the user constants.
• When initialized, the user constants will return to their factory preset values. You should
normally record the setting of any constants that are changed from factory presets.
Setting
A1-03=0
(Initial setting)
A1-03=1
Function
Returns to initialize Display without initializing any user constants.
Initializes the user constants to factory settings.
Battery charger / inverter COMBI-GAMMA
090138.02 53
A1-04: Init Password 1
• This constant is reserved for the factory to test and set the functions.
• Users are not allowed to set this constant.
Lock the constants setting (A1-01=1)
1.
Finish setting all the programmable parameters to the desired values.
2.
Change A1-01=0 (Operation only), factory setting is A1-01=1 (Constant set).
3.
Go to A1-04 and press RUN/STOP key and UP key at the same time till A1-05 parameter
occurs.
4.
Enter the desired password (max. 4 digits)
5.
Press UP key to leave A1-05
Above procedure completes locking the constants setting and no more programming selection would appear. A1-01 would only display 0 (Operation only) and would not display
1 (Constants set).
Unlock the constants setting
1.
Enter the password in A1-04 to be exactly the same as the one earlier set in A1-05
2.
When the password in A1-04 matches the one earlier set in A1-05, the unlocking is completed. A1-01=1 (Constants set) would appear again for programming.
B Group (General):
B1 Group (Output Frequency)
B1-01: Output frequency
• B1-01 is used to set the output frequency at INVERTER AC output
Setting
Function

• B2-08: AC IN Frequency Range
Setting
Function
When B1-01=0: Acceptable AC input frequency is 50Hz ±5Hz (45~55Hz)
B2-08=0
When B1-01=1: Acceptable AC input frequency is 60Hz ±5Hz (55~65Hz)
B2-08=1
(Initial setting)

B2 Group (Auto Transfer Switch)
B2-01: AC IN Low Disconnect
• Use constant B2-01 to determine the AC IN voltage below which level the ATS (Auto
Transfer Switch) will switch off.
• This voltage level will always lie below the AC IN Low Connect (B2-02) level. In fact,
changing this level will also change the AC IN Low Connect (B2-02) level.
B2-02: AC IN Low Connect
• This setting forms a pair with AC IN Low Disconnect (B2-01). With this setting, one determines the AC IN low voltage at which level the ATS will switch on. This should lie above
AC IN Low Disconnect (B2-01) level to prevent continuous switching off the ATS when
the voltage is fluctuating around the level.
• In fact, the parameter which is changed is the difference between AC IN Low Disconnect
(B2-01) and AC IN Low Connect (B2-02).
• The result of this is that when changing B2-01 level, this level (B2-02) also changes.
*Note: B2-02 can be ignored for a short time when AC IN Waveform Check (B2-06) is
disabled (B2-06=0)
• When the AC IN voltage drops due to the increasing charge current, the AC CHARGER
will take care that the voltage does not drop below this level.
• B2-02=B2-01+offset voltage
B2-03: AC IN High Connect
• This setting forms a pair with AC IN High Disconnect (B2-04). With this setting, one
determines the AC IN high voltage at which level the ATS will switch on. This should lie
below the AC IN High Disconnect (B2-04) level to prevent continuous switching of the
ATS when the voltage is fluctuating around that level.
• In fact, the parameter which is changed is the difference between AC IN High Disconnect (B2-04) and AC IN High Connect (B2-03).
• The result of this is that when changing B2-04 level, this level (B2-03) also changes.
• B2-03=B2-04–offset voltage
B2-04: AC IN High Disconnect
• Use constant B2-04 to determine the AC IN voltage above which level the ATS will switch
off.
• This voltage level will always lie above the AC IN High Connect (B2-03) level. In fact,
changing this level will also change the AC IN High Connect (B2-03) level.
B2-05: AC IN Current Limit
• Use constant B2-05 to set the specific maximum AC input current. This value is very
important for both battery charger and inverter output load support.
• When using constant B2-05, the values determine the actual AC current limit.

*Note: With Load Support enabled, there is a minimum value for the AC input current
limit. Please see the note at Load Support (page 60).
B2-06: AC IN Waveform Check
• Use constant B2-06 to enable/disable the fast detection of input voltage wave shape.
Setting
Function
B2-06=0
(Ignore)
• By disabling AC IN waveform check, AC IN Low Disconnect (B2-01) is ignored. When the
load current is higher 1.5 times than AC In Current Limit (B2-05), this is used to prevent
unnecessary switching to INVERTER due to voltage drop when a high load is connected.
B2-06=1
(Initial setting)
(Active)
• This detection checks the wave shape, if it is not sinusoidal within certain limits, the AC
input voltage is rejected.
• However, certain generator or very weak mains supply have an ill shaped sinusoidal
output especially when the load suddenly changes. The fast detection will detect a failure
in such a case.
• This will result in a slightly longer transfer time.
B2-07: Ground Relay
• Used to enable/disable the internal ground relay functionality. The ground relay is useful
when an earth-leakage circuit-breaker is part of the installation.
• When ATS (Auto Transfer Switch) is open (INVERTER mode), the Neutral of the inverter
is connected to “Ground” terminal.
• When ATS closes (AC IN is transferred to AC OUT), the Neutral is first disconnected
from “Ground” terminal.
Setting
B2-07=0
B2-07=1

Function
The internal ground relay is open with “G” terminal.
The internal ground relay is closed with “G” terminal.

B2-09: AC IN Dynamic Current Limit
• This setting is an expansion of the AC IN Current Limit (B2-05) mechanism.
Setting
B2-09=0
(Initial setting)
56 090138.02
Function
• The AC current limit is specified by the AC IN Current Limit (B2-05) setting
Battery charger / inverter COMBI-GAMMA
B2-09=1
• The effective AC input current limit depends on the load history. When the load is
lower than the AC IN Current Limit (B2-05), the effective AC input current limit is
also lower but slightly above the load.
• When the load increase, the effective current limit also increases with a delay. The
thought behind this is that when a generator is running at a low load, it can’t switch
to full load immediately and it needs some time to increase the power.
*An example:
• We have a 2KVA generator.
We adjust the AC IN Current Limit (B2-05) setting to 8A and we enable Load Support
(C1-05=1). We have no load connected and the batteries are fully charged. Therefore,
no current from the generator is drawn.
• At this moment, we connect a load of 7A to the Combi-Gamma with this setting (B2-09)
disabled, the Combi-Gamma would not react because the load is below the AC IN Current Limit (B2-05) setting. The result is that the full load is connected to the generator
which will drop in voltage because it can’t deliver that current instantly which could result in switching to the INVERTER.
• If however we had this setting (Dynamic Current Limit) enabled, the effective AC input
current limit would be far lower than 8A because the load was zero. So connecting a
load of 7A will result in Combi-Gamma starting to Load Support and no voltage drop is
being examined on the AC OUT. The generator starts to supply the load and the effective
AC input current limit will increase to 8A slowly. At the moment, the Combi-Gamma will
stop Load Support and the full load is on the generator.
• This is a powerful option in combination with Load Support but also without Load Support, it can prevent unnecessary switching to the INVERTER because the charge current will reduce when the AC input current becomes higher than the effective AC input
current limit.

• B2-10~B2-13 are used to set the condition of ATS to be ON/OFF in MODE4
• B2-14~B2-17 are used to set the condition of ATS to be ON/OFF in MODE3
• When Combi-Gamma is in either MODE4 or MODE3, the INVERTER mode takes priority to supply voltage to the AC OUT for load consumption. When AC IN power is ready,
the INVERTER is active and the battery is about to be exhausted, ATS will be switched
on to ensure the AC OUT will continuously supply the load. At the moment, AC OUT will
be supplied by the AC IN power. At the same time, the battery can be charged by other
renewable energy such as a solar charger, wind charger or a DC generator charger
(MODE3) which is normally the solar house application in no need of an AC CHARGER.
The battery can be charged by AC IN (AC CHARGER) or other renewable energy such
as a solar charger, wind charger or DC generator charger (MODE4) which is normally
the application requesting both AC charging and DC charging.

• When the battery charger slowly reaches a certain level, this means the battery will be
fully charged soon and the ATS will be switched off for the INVERTER to take over the
ongoing supply to AC OUT for load.
• B2-10 and B2-11 are used to set ATS to be “ON” when the battery voltage is lower than
B2-10 voltage value and longer than the second time set in B2-11 in MODE4
(INVERTER OFF+ATS ON+AC CHARGER ON)
• B2-12 and B2-13 are used to set ATS to be “OFF” when the battery voltage is higher
than B2-12 voltage value and longer than the second time set in B2-13 in MODE4.
(INVERTER ON+ATS OFF+AC CHARGER OFF)
• B2-14 and B2-15 are used to set ATS to be “ON” when the battery voltage is lower than

• B2-16 and B2-17 are used to set ATS to be “OFF” when the battery voltage is higher
than B2-16 voltage value and longer than the second time set in B2-17 in MODE3.
(INVERTER ON+ATS OFF+ AC CHARGER OFF)
B2-18: MODE1: ACIN Current Lmt
• Use constant B2-18 to set the set the specific maximum AC input current in MODE 1.
This value is very important for both battery charger and inverter output Load-Support.
• When using constant B2-18, the values determine the actual AC current limit.
B2-19: MODE2: ACIN Current Lmt
• Use constant B2-19 to set the set the specific maximum AC input current in MODE 2.
This value is very important for both battery charger and inverter output Load-Support.
• When using constant B2-19, the values determine the actual AC current limit.
B2-20: MODE3: ACIN Current Lmt
• Use constant B2-20 to the specific maximum AC input current in MODE 3. This value is
very important for both battery charger and inverter output Load-Support.
• When using constant B2-20, the values determine the actual AC current limit.
B2-21: MODE4: ACIN Current Lmt
• Use constant B2-21 to set the set the specific maximum AC input current in MODE 4.
This value is very important for both battery charger and inverter output Load-Support.
• When using constant B2-21, the values determine the actual AC current limit.

B3 Group (Parallel System)
B3-01: Number of Slaves
• A parallel system is built with 1 master and up to 4 slaves with this setting, one can specify the number of slaves in the system. This setting has only to be done in the master.
It is not required to specify the number of slaves. The system will work just fine without
this setting being specified.
• This setting is added for convenience of the end-user when the AC IN power is larger
than the total of B2-05* the number of the Combi-Gamma (Master + Slaves) when B301=0. The only effect of this setting is on the scaling of AC IN Current Limit (B2-05). If
B3-01=0, one must divide the available AC current by the number of Combi-Gamma
(Master + Slaves) and set the limit accordingly. So an example of setting the B2-05=10A in a parallel system with 3 Combi-Gamma would result in a limit of 3*10A=30A
• If however in this system the number of slaves is set to 2 (B3-01=2), then the division is
done internally and the setting of the AC IN Current Limit to 10A (B2-05=10) will result
in 10A for the whole system and this is shared by the Master and Slaves. This system
is often applied when the AC IN power is limited for example by a generator of small
capacity.
B4 Group (2-3 Phase)
B4-01: 2-3 Phase Connection
• All the Combi-Gamma in a multi-phase system must have 2-3 phase enabled. Use this
setting to perform this function.
• If more Combi-Gamma per phase are connected in parallel, then only the masters of the
parallel system must have 2-3 phase enabled.

2-3 Phase connection disabled.
B4-01=1
2-3 Phase connection enabled.
B4-02: 2-3 Phase Master
• In a multi-phase system, there is always one (and only one) master. The Combi-Gamma
at the other phases are called slaves.
• Use this setting to designate one of the Combi-Gamma as the master.
• If this parameter is set (B4-02=0), the Combi-Gamma becomes a slave.

C Group (INVERTER):
C1 Group (INVERTER)
C1-01: INVERTER Output Voltage
• Use constant C1-01 to change the RMS output voltage of the INVERTER.
C1-02: Bat Low - V Shut-down
• With this setting, one can determine the battery voltage at which level the INVERTER will
switch off. This can be useful to prevent drawing too much current from an exhausted
battery.
• This voltage level will always lie below the Bat Low - V Restart (C1-03) level. In fact,
changing this level will also change the Bat Low - V Restart (C1-03) level.
• C1-03=C1-02+offset voltage
C1-03: Battery Low ? V Restart
• This setting forms a pair with Bat Low - V Shut-down (C1-02). With this setting, one determines the battery voltage at which level the INVERTER will switch on.
• In fact, the parameter which is changed is the difference between Bat Low ? V Shutdown (C1-02) and Bat Low ? V Restart (C1-03). The result of this is that when changing
the Bat Low ? V Shut-down (C1-02) level, this level also changes.
C1-05: Load Support Select
• Using this constant C1-05, the Load Support feature can be enabled or disabled. Use
Load Support to prevent an external circuit breaker to trip when the load on the CombiGamma is too high.
• If the load exceeds the AC IN Current Limit (B2-05), the Combi-Gamma will start inverting and will provide the extra current needed.
*Note: When Load Support is enabled. C1-05=1 (Initial setting), there is a minimum
AC input current limit of approximate 2-3 Amps. Setting a lower limit (B2-05) than this
60 090138.02
Battery charger / inverter COMBI-GAMMA
minimum value will result in the minimum limit. (Note: In a parallel system, this limits
per Combi-Gamma!)
Setting
Function
C1-05=0
Load Support Function is disabled.
C1-05=1
(Initial setting)
Load Support Function is enabled.
C1-06: Load Support Level
• This setting is a special setting for load support mode when the Combi-Gamma is charging and due to a sudden load, the AC IN current exceeds the AC IN Current Limit (B205), the Combi-Gamma will switch to load support mode (when C1-05=1)
• At that moment, the current need is unknown. The Combi-Gamma makes an assumption of the magnitude of this current. This assumption is equal to AC IN Current Limit
(B2-05) multiplied by this Load Support Level (C1-06). The default factor is two.
• This will prevent the circuit breaker from tripping because current provided by the INVERTER minus the current drawn by the load is always lower than the rating of the circuit breaker. This happens, of course, when the AC IN Current Limit (B2-05) is correctly
adjusted on the circuit breaker.
• If for instance in a generator application, the circuit breaker has a higher value than the AC
IN Current Limit (B2-05)(Normal load of generator is lower than maximum peak load) and
one knows that the load which is switched on always draws a certain current, one can consider to increase this factor (C1-06) to achieve better results with sudden load changes.
D Group (AC CHARGER):

D1-02: Charge Curve
Setting
Function
D1-02=1
Fixed
D1-02=2
Adaptive
D1-02=3
(Initial setting)
Adaptive + Battery safe
• The Fixed (D1-02=1) charge curve will have a fixed Absorption Time (D1-06).
• The Adaptive (D1-02=2) and Adaptive +Battery safe (D1-02=3) curve derive the Absorption time from the Bulk time. The maximum Absorption time of these charge curves
is determined by Absorption Time (D1-06) setting.
• The Adaptive + Battery safe (D1-02=3) curve has a special regulation in the absorption
phase. The absorption phase will start when the battery voltage reaches 14.4V( for 12V
batteries) regardless of the specified Absorption Voltage (D1-03). During the absorption
phase, the voltage will increase with a fixed ramp until the voltage reaches the absorption voltage or the calculated absorption time is over in the latter case, the absorption
phase will end before the absorption voltage is reached.

D1-04: Repeated Absorption Time
• Use this setting to specify the duration of the repeated absorption “pulses”.
D1-05: Repeated Absorption Interval
• Use this setting to specify the interval between repeated absorptions.
D1-06: Maximum Absorption Time
• If the Charge Curve is fixed (D1-02=1), then this setting is used to determine the absorption time.
• In all other cases, this setting determines the maximum absorption time.
D1-07: Float Voltage
• Use this setting to specify the float voltage.
D1-08: Charge Current
• Use this setting to specify the current with which the battery is charged in the bulk phase.
*Note: The actual charge current depends on other conditions also. Therefore, under
certain circumstances, it is possible that the actual charge current is lower than this
setting. This can, among others, be due to:
• A low AC IN Current Limit (B2-05) in combination with a high load.
• A high environmental temperature
• A too high ripple voltage due to improper cabling.

D1-09: Stop After 10Hr Bulk
• This is a safety setting. When the bulk phase lasts more than 10 hours, this can be indication that a battery cell is damaged.
• The absorption voltage (or the 14.4V for battery when Battery Safe (D1-02=3) mode is
used) will never be reached in that case and the other cells will be over-charged resulting in the production of an explosive gas.
• Therefore, the charger is disabled if the bulk phase lasts more than 10 hours.
• This setting can be disabled because it does not always indicate a problem when the bulk
phase lasts very long. The charge current can be very low due to limited AC input current
and/or AC loads. Also, DC loads can “steal away” part of the charge current. In that case,
the bulk phase will need more time to complete and this setting must be disabled.
*Note: When this setting is disabled, there is no safety check to protect against
over-charging.
