The light-weight and compact construction of this device allows for easy installation
in mobile homes, commercial vehicles or motor and sailing yachts.
The output voltage corresponds to the household voltage from the socket (pure sine
wave, THD <3 %).
Please observe the values for constant output power and peak output power as
indicated in chapter “Technical data” on page 29. Never connect devices that have
a higher power requirement.
I
The priority circuit reduces the load on a connected battery by switching the device
always to mains operation if AC power grid is connected. The device ensures that a
connected load is supplied with voltage:
• In case the AC grid power breaks down or is unstable
• In case the AC grid power does not suffice to supply the connected consumers
The device has various protective mechanisms.
•Overvoltage shutdown: The device shuts itself off when the voltage of the
connected DC source exceeds the cut-off value. It restarts when the voltage
returns to the restart value.
•Undervoltage shutdown: The device shuts itself off when the voltage of the
connected DC source sinks below the cut-off value. It restarts when the voltage
rises to the restart value.
•Excess temperature shutdown: The device switches off when the tempera-
ture inside the device or the temperature on the cooling element exceeds a cut-
off value. It restarts when the temperature falls to the restart value.
•Overloading and short circuit shutdown: The LED on the device indicates
an operating fault when an excess load is connected or a short circuit has
occurred.
I
NOTE
Note when connecting devices with an electrical drive (such as power
drills and refrigerators), that they often require more power than is
indicated on the type plate.
NOTE
The individual values are found in the chapter “Technical data” on
page 29.

7.3 Control elements DSP-EM
7.4 Description of 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
DSP-EM. 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 (values for illustration purpose only):
I
Generator function (external mains power supply)
A
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. While doing so, the battery is discharged.
The generator mode can manually be shut off via DSP-EM to ensure that the battery
will not be discharged.
If the battery‘s voltage or capacity does not suffice to support the grid the device is
disconnected from the grid and the inverter tries to work in isolated operation.
NOTE
Keep in mind that the device only measures the current which flows
through the device. If you connect more consumers in parallel, e. g.a
refridgerator or an separate charger, this additional load may trip the
fuse. In this case,set the power sharing level value below the fuse‘s value
accordingly.
NOTICE!
Observe the standards that apply in your country to the generator
function.

Example (values for illustration purpose only):
Battery charging function
I
The battery is charging with IU0U characteristics (fig. g).
1: 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 the charging end
voltage. The charging current decreases when the battery has reached this charging
level.
2: 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. The voltage
remains constant until the minimum charging current (6 % of the set current) or the
maximum charging time (10 hours) is reached.
3: 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.
NOTE
If a battery sensor (accessory) is connected, the device adjusts the
voltage according to the measured values.
For this purpose the battery sensor has to be configured with DSP-EM.
