Please check if the unit has no visible damage. If the unit is damaged you must inform your dealer
within 3 days after receiving the unit.
4 Function, technology
This inverter is designed to convert DC-battery voltage (direct voltage) to 230V AC (sinusoidal al-
ternating voltage). Voltage controlled, the inverter provides a stabilised, crystal-accurate alternating
230V/50Hz voltage (different voltages and frequencies refer to the indication label). With a sine-
wave inverter almost any type of electric consumer may be connected as for example energy saving
lights, uorescent tubes, computers, Radio- and HIFI-equipment and other household appliances,
freezers, pumps, motors etc. Due to a high degree built-in safety, excellent dynamic response, a
surge-proof and overload-proof output, it is very simple to operate a broad range of applications.
The „heart“ of the inverter is a very powerful RISC-microprocessor of the latest generation. This
microprocessor is responsible for the real time computing of the output sine-wave shape, for the
process control of the output voltage, for the supervision of the battery (dynamic) and the inverter
temperature. The power stage features modern Power Mosfet transistors. These transistors are the
key to the high partial-load efciency and superb overload capability. The power transistors are pro-
tected by independent intelligent protection circuits. The inverter is further more protected against
DC-over voltage (static) and short circuit on AC-output. The battery input side is equipped with a
thermal/magnetic circuit breaker to protect of your system.

Safety Instructions
5 General information
Always check the power draw of your appliances. Electrical equipment as motors, pumps, compres-
sors etc. need more power while starting up. Start up power draw can be much higher than Pnom.
For these applications the inverter is able to supply up to 300% surge power for a short time. Be
careful if you use pumps. Power declaration on pumps is normally not the electrical input power of
the pump! The inverter switches off automatically if surge power is too high. If ambient temperature
is higher than 20° C, Pnom and overload capability of the inverter will be reduced. Due to reduced
cooling capacity, Pnom of the inverter is reduced if operation altitude is above 900m ASL. Reduction
of Pnom is approx. 1.5% per every additional 100m more altitude. Example: If a 1000VA inverter is
installed as high as 2500m ASL maximal Pnom will be at 780VA only! If you use more power, over-
heating and associated premature disconnection of the inverter must be anticipated. If you use the
inverter under above conditions we recommend using a well over dimensioned inverter.
• Be sure the points demanded under „safety regulations“ are obeyed.
• Install the unit in a dry place. The unit is not designed for outdoor use.
• Adequate ventilation. Keep min. 10cm distance to other objects (except mounting
side). Do not cover heat sink!
The selection of a safe location for installing the inverter depends on the following criteria:
• Check indication label for correct DC-Voltage and AC-Voltage.
• The inverter can be used in any position.
• Protection from unauthorised access in particular of children’s.
• Dry, dust free surroundings (max. 95% humidity, not condensing).
• Short distance between battery and inverter. Use a grounded metal pipe to reduce RFI emissi-
on and to prevent surroundings of re. The inverter should not be mounted in the same room
as the batteries are (gas of the batteries during charging).
• Adequate ventilation. Keep min. 10cm distance to other objects (except mounting side).
• Battery capacity must be at least 200Ah. Using a smaller battery may reduce performance of
the unit.
• If other DC-units are installed at the same battery, contact your dealer for more information’s
• Protection of inverter and battery from the effects of water.
• Temperature range –25°C to +50 degrees C.
• Only specially trained maintenance and service personnel are permitted to test this unit. These
personnel further must be familiar with this manual and all domestic regulations before instal-
ling this unit.

Safety Instructions
• Be sure the points demanded under „safety regulations“ are obeyed.
• Check whether the intended solar generator voltage corresponds properly with
the type-label on the unit itself.
• Any electrical connections must be carried out by an electrical specialist.
• The large input capacitors may still be charged even if DC-cables are disconnec-
ted and DC-switches are in OFF position!
The DC-circuit breaker must be turned to OFF-Position. Note: Inbuilt, large capacitors will hold DC-
Voltage for extended periods. They still can have DC-Voltage even when the switch is in off position
and the DC-Cables are disconnected from the battery! First make AC-Connections. Connect your
load with enclosed connector to the inverters AC-Output. An additional AC-Circuit breaker (size re-
fer to datasheet) has to be installed. We recommend installing an earth leakage protector for protec-
tion of personnel. Please observe domestic regulations when making connections! To connect the
Battery to the inverter uses a wire with minimum cross section of 25mm2. An additional DC-breaker
must be installed direct at the battery. Before connecting the cables to the battery make sure that
the polarity is correct! Applying of wrong polarity may damage the inverter.
NOTE: Please exercise extreme care when connecting the unit to a battery. Otherwise the inverter
or the battery could be damaged!

Take care of correct grounding of the inverter and your equipment that is connected to the inverter!
We recommend using an earth cable with minimum cross section of 10mm2to ground the inverter.
This will help to protect your unit in case of lightning. Be sure to meet all regulations about lightning
protection! Check again to make sure all cables are securely connected. Switch on the DC-Circuit
breaker. The inverter is now ready to operate.
8 Information’s for operation
Security advices
• Be sure that all demands written in the topic „safety regulations“ are kept.
• If DC voltage is out of range longer then 5 sec., the inverter switches off auto-
matically, LED indication “LOW BATERY” ashes red. Caution: As soon as DC
voltage is back in tolerance the inverter switches automatically on again.
• If AC voltage is out of range, LED indication “AC-OUTPUT” turns to red. The
inverter switches off automatically and indication “AC-OUTPUT” ashes red.
Caution: After approx. 20 sec. the inverter tries to switch on automatically again.
• Each time a fault occurs, the inverter restarts automatically after 20 seconds or if
the parameters (for example temperature) are back in normal conditions after a
fault. Time before the unit starts again can be from a few seconds to a few hours!
Always switch off the unit if you work at your system or electric consumer.
• For any manipulations and works on the electrical facility or AC-load, always
cut off the inverter from the battery (turn DC-switch rsp. circuit breaker to OFF
position).
• Inverter heat sink may be very hot, do not touch surface to reduce the risk of
burns.
Protect your inverter from rain. The unit is not designed to be used outdoor.
The DC-input breaker should be in „ON“-position all the time. In case of an error it will switch of
automatically. If the inverter is switched off (by turning the potentiometer fully counter clockwise) it
still needs app. 25mA from the battery. The inverter is electronically short circuit protected at the AC-
Output. DC input of the inverter is monitored for over voltage and under voltage. The upper limit is
static. If DC-Voltage is too high the inverter will switch off. Automatic restart follows after DC-Voltage
is in the normal range. The lower limit is dynamic (cut off voltage is lower if a big load is in use). This
allows an optimal use of the battery capacity and protects your battery during small load operation.
Important: If the inverter has switched off automatically it still needs very little power from the
battery!
Important: Always before you switch on the circuit breaker you must switch off the load.
The fan is controlled by temperature and power needed. It is helping to reduce problems of over-
heating.
