Introduction
General
Multi-functional Feature•
The “Combi-Gamma” is a powerful true sine wave inverter, a sophisticated battery char-
ger 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 in-
verter 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 con-
nected 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 manage-
ment 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
Battery charger / inverter COMBI-GAMMA
090138.02 5
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 gas-
sing 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, Sun-
Star-45 or SunStar-60 (optional) to be used with solar panel to charge the battery. Com-
bi-Gamma sends the 4-stage charging command to extensional Solar Charger via port
C (Extension Port) for the best quality of solar charging.

B1-01 is used to set the output frequency at INVERTER AC output•
Setting Function

B1-01=1 60Hz at INVERTER AC output
B2-08: AC IN Frequency Range•

(Initial setting)
Accept wide AC input frequency range between 45~65Hz
Battery charger / inverter COMBI-GAMMA
090138.02 55
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 deter-
mines 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 Discon-
nect (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.•
Battery charger / inverter COMBI-GAMMA
56 090138.02
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 Function
B2-07=0 The internal ground relay is open with “G” terminal.
B2-07=1
(Initial setting)
The internal ground relay is closed with “G” terminal.
B2-08: AC IN Frequency Range
Refer to (B1-01)
B2-09: AC IN Dynamic Current Limit
This setting is an expansion of the • AC IN Current Limit (B2-05) mechanism.
Setting Function
B2-09=0
(Initial setting)
The AC current limit is specified by the • AC IN Current Limit (B2-05) setting
Battery charger / inverter COMBI-GAMMA
090138.02 57
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 Cur-
rent 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 re-
sult 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 Sup-•
port, it can prevent unnecessary switching to the INVERTER because the charge cur-
rent 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 prior-•
ity 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 “OFFwhen 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 •
B2-14 voltage value and longer than the second time set in B2-15 in MODE3.
(ATS ON+INVERTER OFF+AC CHARGER ON)
B2-16 and B2-17 are used to set ATS to be “OFFwhen 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 spec-•
ify 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 B3-
01=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.
Setting Function

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.•

Three Combi-Gamma are required.
Output is 3-phase with a 120° phase shift.

Output is 2-phase of a normal 3-phase system (two phases with 120° phase shift).
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 de-
termines 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 Shut-•
down (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 Combi-
Gamma is too high.
If the load exceeds the • AC IN Current Limit (B2-05), the Combi-Gamma will start invert-
ing 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
Battery charger / inverter COMBI-GAMMA
090138.02 61
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 charg-•
ing and due to a sudden load, the AC IN current exceeds the AC IN Current Limit (B2-
05), 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 assump-•
tion 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 IN-•
VERTER minus the current drawn by the load is always lower than the rating of the cir-
cuit 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 con-
sider to increase this factor (C1-06) to achieve better results with sudden load changes.
D Group (AC CHARGER):
D1 Group (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 Ab-
sorption 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 absorp-
tion voltage or the calculated absorption time is over in the latter case, the absorption
phase will end before the absorption voltage is reached.

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 indi-•
cation 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 result-
ing 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.
