Product description
The new IBS Ultra Sine inverters for island operation in mobile or stationary applications produce pure
sine wave alternating voltage with 230VAC / 50Hz from 12V or 24VDC battery voltage. Latest
technology allows the construction of lightweight and compact inverters. High-frequency hi-tech
transformers with a powerful software-controlled IGBT transistor bridge guarantee impressive
performance. The latest generation has reduced its own consumption by 30% to 1.2A @ 12.3V / 1.1A
@ 24.6V, which is ideal for use in insulated solar systems. Consumers such as hairdryers, vacuum
cleaners, coffee machines, hand-held machines, computers, laser printers, measuring instruments,
medical devices can be operated in most cases.
Applications
•Motorhomes, Camper
•4WDs / Expedition / Rallye
•Yachting
•Solar (island installations)
•Commercial and industrial use
•Energy back-up for computers, communications and medicine
•Mobile power for craftsmen

Special features
DSC (Dynamic Surge Control)
The inverter is equipped with dynamic surge control. The more battery capacity or charging current
support (alternator) is available, the larger consumer devices can be started. If the starting current
exceeds the safe value, it results in a safety cut-off (red error LED flashes), reset by switching the
inverter off and on again.

Protection of deep discharge of the battery
The inverter is equipped with an intelligent, current-dependent deep-discharge circuit. Switch-off value
11.8V / 23.6V, re-activation 12.3V / 24.6V. Immediate shutdown when battery drops below 10.5V /
21.0V.
Performance
The IBS inverters are very powerful, as long as the batteries provide the necessary energy. Use as
much charged, high-performance batteries as possible. Recommended battery capacities
see P. 8. If the inverter is used for a long period, allow the engine to run for support (continuous
currents up to 150A and starting currents up to 350A / 180A are possible). If charging support is
provided by alternator or solar / charger (U> 13.0V /> 27V), the starting power according to DSC class
S1 is available.

Warning
Have the wiring carried out by a qualified technician. Before the Connection is started, make sure that
all cables and connections are voltage-free. Short circuits and polarity reversal can lead to serious
damage to the battery, the Ultra Sine inverter and the electrical installation. Fuses cannot prevent
damage caused by polarity reversal. Such damages are not included in the warranty.
Inverter output cannot be connected to the public network! (Use US-TS for automatic landline / inverter
switching)
Never insert objects through the openings and ventilation slots of the device!

Installations
Recommended cable cross section
When using a thinner cable cross-section than recommended, large losses and dangerous heating can
occur in the connection cable. This may cause the Ultra Sine inverter to fail its full performance.

Installation Steps
Wiring
Abb. 7 Cabling normal use
Abb. 8 Cabling with US transferswitch
Warning: Ensure correct polarity! Closing the circuit can cause a spark! Never connect the AC output of
the inverter to the public network!
Caution: When installing the USTS FI, please consult the manual for instructions and safety
instructions!
A main switch (S1) must be provided to allow emergency disconnection of incoming shore power
supply!
In mobile applications such as
travel trailers or yachts with a
possible landline, the two-230V
networks (inverter and landline
connection) may only be
connected via the US-TS FI
switch! The same applies if 230V
emergency generators are used!
For parallel IBS operation, use
the US-TS FI transfer switch.

Grounding
The grounding scheme of the US Inverter G4 is as follows:
Connecting the consumer device
Connectors for device
The Ultra Sine inverter is equipped with a socket according to IEC 60320-1 C13. A plug according to
IEC 60320-1 C14 must be used as a counterpart.
Commissioning the unit
Connect the remote control
Plug the connection cable of the remote control into the remote control plug.
A non-crossed 8-pin RG45 cable must be used.
Switching on the appliance
To switch the device on and off, press the on / off button on the front of the device or the button on the
RP03 remote control.
Activating / deactivating standby
To activate or deactivate standby, press the on / off button on the front of the device or the button on the
remote RP03 remote for 3 seconds until the middle LED (orange) lights up (continuous operation active)
or extinguishes (standby active).

Attaching the mounting feet

Screw the mounting feet to the intended positions using the screws supplied. Only the included screws
may be used. The tightening torque is 1.1 Nm.

17
Fitting
•Mount the unit with the mounting feet on a surface. Mounting is possible on a surface, on a
sidewall or upside down.
•The ventilation slots and the fan must not be obstructed, so that the warm air, which is
generated during operation, can escape unimpeded. Do not install in a small enclosed space,
ensure air circulation.
•Ensure that no objects, dust or dirt can enter the interior of the unit through the ventilation slots
or fan.
•Avoid any contact with water, moisture or rain. Humidity: 0-95%, non-condensing.

18
Please note
In order to guarantee the perfect operation of your IBS Ultra Sine inverter, please note the following
points:
1. Inverter and battery voltage must be the same. Operation of a 12V device at 24V leads to
destruction of the inverter.
2. The battery must be charged. If an inverter is operated with high power, the battery can be
discharged quickly. If the battery voltage is too low, the inverter switches off and can only be
switched on again after charging the battery.
3. High continuous load in case of insufficient cooling can lead to an emergency shutdown. The
fan supports cooling depending on current and temperature.
4. Observe the same safety regulations as when using the 230V public network. When using the
inverters, an additional fuse of 150A (12V) / 80A (24V) is recommended directly at the battery
connection or circuit breaker (automatic fuse).
