Technical description

General description

The inverter charger combination is a combination of a DC-to-AC sine wave inverter with an integrated battery charger.

If 230 V mains is available, this external power source can be used both to supply the sockets in the recreational vehicle and for charging the vehicle battery.

If no 230 V mains is available, the inverter converts the battery's direct current into alternating current, thus ensuring the power supply for the connected consumers.

The inverter charger combination offers the following functions:

- Automatic mains priority switching: Allows to supply the AC sockets from different voltage sources. If no 230 V mains is available, the inverter can take over the supply of the sockets. When 230 V mains are connected, the device synchronizes and the AC sockets are then supplied by the mains.

• AC input current boost: Temporary support of weak AC input sources with additional energy from the house battery when high starting currents are needed (e.g. air conditioner) or the connected load requires more power than is available from the mains or a 230 V generator
• Mains input current limitation: Limitation of the 230 V mains input to a maximum available current
• Power factor corrected mains input: Optimizing energy efficiency and providing the maximum possible charging current of the AC power source with connected loads
• Microprocessor-controlled, temperature-compensated IUOU charging programs for various battery types
• Integrated load detection: Automatic standby of the inverter in case of prolonged non-use (after 10 minutes)
• Automatic shutdown: Avoiding unnecessary power consumption, the device automatically switches off when no mains is available

The inverter charger combination has the following protective mechanisms:

• High battery voltage shutdown
- Low battery voltage shutdown
- Low input voltage protection
• High input current protection
• High temperature shutdown
- Low temperature protection (only LiFePO4 batteries)
• Protection against short circuit
• High ripple protection

The inverter charger combination can be adapted to different battery types via DIP switches (see chapter "Setting the charging program" on page 23).

The temperature sensor monitors the battery temperature during the charging process.

The inverter charger combination is equipped with a remote control.

Battery charging function

The selectable charging programs (see chapter "Setting the charging program" on page 23) perform a charging process in four phases, referred to as IUOU characteristics.

1: Constant current phase (Bulk)

The battery is constantly charged with the maximum charging current (100%). The charging current decreases when the battery has reached a state of charge of 75% (90% for LiFePO4 batteries). The duration of the constant current phase depends on the condition of the battery, the load from the DC loads and the state of charge.

2: Constant voltage phase (Absorption)

The constant voltage phase starts when the absorption voltage (U1) is reached. The charging current is reduced depending on the state of charge. During the constant voltage phase, the battery voltage is kept constant at a high level and the state of charge is increased to 100%. The duration of the constant voltage phase depends on the battery type, but is terminated after a maximum of 4 h (absorption time-out).

3: Trickle charging phase (Float)

The trickle charging phase starts when the charging current falls below a minimum value or the absorption time-out has been reached. The trickle charging phase serves to maintain the state of charge (100 %) and runs at lowered charging voltage (U2) and variable current. If DC loads are connected, they are powered by the device.

If the power required exceeds the capacity of the device, this surplus power is provided by the battery and the battery voltage drops. As soon as the battery voltage has dropped to a certain value the device re-enters the constant current phase and charges the battery.

4: Reconditioning phase (Pulse)

Once a week, the device switches back to the constant voltage phase for a short time (max. 1 h) in order to revive the battery. This prevents any fatigue phenomena such as sulfation or electrolyte stratification.

Temperature sensor

With the temperature sensor connected the inverter charger combination adapts the charging voltage (for lead batteries) or the charging current (for LiFePO4 batteries) according to the measured temperature at the battery.

NOTE

- Charging voltage adaptation: 30 mV/°C (referenced to 20 °C)

- Charging current adaption: Charging current reduction up to 10% of the maximum charging current (at battery temperatures <0 °C) or to 0% (at battery temperatures >52 °C)

Alarm relay (only MT ICC 1600 SI-N)

NOTICE! Damage hazard

Ensure that the maximum relay contact load is not exceeded to avoid damage to the relay: 30 V---/1 A or 60 V---/0.3 A.

• The alarm relay is activated as soon as the AC power supply is available and the AC transfer switch is closed. The alarm relay can be used to:
• Generate an AC power supply detection signal in the vehicle control panel.
• Switch on and off less critical loads (e.g. absorber refrigerator, electrical heating systems) that should only be operated in connection with AC power supply.

Programmable relays (only MT ICC 3000 SI-N)

NOTICE! Damage hazard

Ensure that the maximum relay contact load is not exceeded to avoid damage to the relays: 30 V==/16 A or 250 V\~/16 A

• The programmable relay 1 (Prog.Relay1) is activated as soon as the device detects an error (see chapter "Error indication" on page 30). The programmable relay 1 can be used to generate an error detection signal in the vehicle control panel.
• The programmable relay 2 (Prog.Relay2) is activated as soon as the AC power supply is available and the AC transfer switch is closed. The programmable relay 2 can be used to:
• Generate an AC power supply detection signal in the vehicle control panel.
• Switch on and off less critical loads (e.g. absorber refrigerator, electrical heating systems) that should only be operated in connection with AC power supply.
• Activate or deactivate the auxiliary charging output.

Trigger input

NOTE

For use of the default or additional functions, the trigger input must be connected (see chapter "Connecting the trigger input" on page 23).

By factory default the trigger input closed or bridged causes a delayed shutdown in the event of a mains failure: The device initially switches to inverter operation. Only when no mains is detected at the AC input within 5 minutes, the device switches off to avoid power consumption of the house battery.

Additionally, the trigger input can be used for external control of certain functions of the device, e.g. to temporarily deactivate the AC input current boost.

Operation

Mains operation: If mains is available, voltage and frequency of the mains input signal are analyzed continuously. As long as voltage and frequency are within the required tolerances, the device synchronizes to the mains input signal. Connected 230 V consumers are supplied from the 230 V input source and the 12 V vehicle battery is charged. As soon as the voltage or frequency exceeds the required tolerances (e.g. no mains voltage is available), the charging process is stopped and the device switches off.

Inverter operation: If no mains is available, the connected consumers can be supplied by the inverter in automatic or continuous mode (see chapter "Setting the automatic mode" on page 26 and chapter "Setting the continuous mode" on page 27).
