6.5 Battery charging function

The charging characteristics are referred to as modified IU0U characteristics.

1: Analysis phase

First, the battery charge is analysed with increasing charge current.

2: I phase (bulk)

At the beginning of the charging process, the flat battery is charged with a constant current (100% charge current) until the battery voltage reaches 14.4 V or 28.8 V. The charging current decreases when the battery has reached this charging level.

3, 4: U0 phase (absorption)

Now the two-stage absorption charging process (U0-Phase) begins, where the charge voltage and duration depend on the size and type of the battery. Different voltages can be set for phases 3 and 4, which remain constant until the maximum charging current (6% of the set current) is reached.

Phase 4 ends no later than 8 hours after 13.8 V or 27.6 V is reached.

Technical description CombiPower

5: U Phase (floating)

The U phase serves to maintain the battery capacity (100%).

If DC loads are connected, they are powered by the device. Only if the power required exceeds the capacity of the device is this surplus power provided by the battery. The battery is then discharged until the device re-enters the I phase and charges the battery.

6: 14-day conditioning

Every 14 days, the battery charger switches back to phase 2 in order to revive the battery. This prevents any fatigue symptoms such as sulphation.

Charging with the battery temperature sensor

The battery temperature sensor supplied with the device needs to be connected. This adapts the charging voltage to the battery voltage. The charging voltage during the U0 phase is increased or reduced according to the battery temperature (see the following diagram):

5 A/2.5 A charger (second battery connection)

The device has a connection for a second battery (3-step charger). You can charge a small battery (such as an automotive battery) using this connection.

The charging voltage is 14.4 ~V or 28.8 ~V . The maximum charging current is 5 ~A or 2.5 ~A .

CombiPower Technical description

6.6 Inverter function

In inverter mode, the device supplies a regulated 230 V voltage.

The maximum constant output is 2000 VA. Do not connect any devices with a higher power rating. If you connect several devices, make sure their total power rating does not exceed 2000 VA.

NOTE

Note when connecting devices with an electrical drive (such as power drills, refrigerators and switched-mode power supplies), that they often need more power than is stated on the type plate.

An adjustable energy saving mode protects the battery. It regularly checks whether battery power needs to be used. If not, the function is deactivated and no idle current is used.

6.7 Connections

A battery is connected to the positive and negative terminals. A 230 V power source can be connected to the "AC INPUT" input (fig. 1 6, page 3). The power supply via "AC INPUT" takes precedence over the battery power supply, so that the battery is not discharged unnecessarily.

Voltage is present at the outputs under the following conditions:

● "INV. AC OUTPUT" (fig. 1 4, page 3)
– A battery is connected
- A 230 V power source is connected
- A battery and a 230 V power source are connected (The battery is charged when the consumer devices do not require all the power)

● "AC OUTPUT" (fig. 1 5, page 3)

- A 230 V power source is connected

EN

Technical description CombiPower

6.8 Enabling functions

The device supports the functions described below.

Power sharing function

If the load from the connected consumer devices and the battery charging current is higher than the connected 230 V power source, the fuse of the power source would normally blow. In power sharing mode, the device reduces the battery charging current and thus increases the power available for connected consumers.

The power sharing level (current at the 230 V input) can be configured using the remote control. If must be adapted to the fuse of the power source. For example, if it has a 10 A fuse, the power sharing level must also be 10 A.

Example:

graph TD
    A["12/24 V"] --> B["AC INPUT 230 V"]
    B --> C["AC OUTPUT"]
    C --> D["230 V"]
    D --> E["INV. AC OUTPUT"]
    E --> F["Device with fan icon"]

CombiPower Technical description

Generator function (external mains power supply)

NOTICE!

Observe the standards that apply in your country to the generator function.

If the load current is greater than the fuse of the connected 230 V power source, the fuse would normally blow. The generator function enables the device to provide additional power, which it takes from the battery.

If the required power falls below the power sharing level, the device recharges the battery.

In generator mode, the 230 V power source and the battery act as a common power source.

Example:

graph TD
    A["12/24 V"] --> B["AC INPUT"]
    B --> C["230 V"]
    D["AC OUTPUT"] --> E["230 V"]
    F["INV. AC OUTPUT"] --> G["230 V"]
    H["Refrigerator"] --> I["Refrigerator"]

Technical description CombiPower

Power support function

If the generator function is not permitted by the standards in your country because the device operates in parallel to the 230 V mains, you can use the support function. The “AC OUTPUT” and “INV. AC OUTPUT” outputs are electrically isolated from each other.

The 230 V power source provides voltage at "AC OUTPUT" while the battery supplies "INV. AC OUTPUT".

If the devices connected to “INV. AC OUTPUT” require more current than the battery can deliver, they are switched off. If the devices connected to “AC OUTPUT” require more current than the set power sharing level (which must correspond to the fuse rating of the 230 V power source), the fuse of the 230 V power source blows. For example, if the power supply at a camp site has a 10 A fuse but the consumer devices required 16 A, the camp site fuse blows.

Example:

graph TD

    E -->|230 V| F["Reverter"]

CombiPower Technical description

Uninterruptible power supply

The device can be used as an uninterruptible power supply. The device powers connected loads from a battery when the mains supply fails

You can use this function, for example, to continue running your air conditioning system if the 230 V power supply fails.

NOTE

You can use the remote control to configure how long the inverter continues operating after a mains power failure. This prevents the battery from deep discharging.
