The “Combi 3” 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 3 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 3 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. 

Power Control-Dealing with limited generator or shore side power: The “Combi 3” is a very powerful battery charger. It will therefore draw a lot of current from the generator or shore side power. A maximum generator or shore current can be set (B2-05). The “Combi 3” will then take account of other AC loads and use whatever is extra for charging thus preventing the generator or shore supply from overload.

Power Assist-Boosting the capacity of shore or generator power: This feature takes the principle of Power Control to a farther dimension allowing the “Combi 3” 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 3” 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 over charging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery 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 3” 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. One 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 3” 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 3” can come with an optional 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 3” is provided with a voltage sense facility so that the battery always receives the correct charge voltage.
