USE

• This device produces a stable, pure sinusoidal voltage.
• This is of a similar quality to that available in mains sockets in buildings.
• It is suitable for operating all equipment – if its power consumption does not exceed the power that can be safely and continuously supplied by the inverter.
• If you connect the rear (230 V~) connector of the inverter to the mains with the included connection cable, the battery can be kept continuously charged.
• This allows the powered equipment to continue operating in the event of a power outage until the grid is restored or the battery runs out.
• Similar to uninterruptible power supplies.
• When switching between the mains and the battery, the operated equipment may turn off for a short time.
• For example, a computer or television may restart at this time.
• The effect of switching and the restoration of operation depends to a large extent on the unique characteristics of the operated equipment.
• If the battery is not exhausted when the mains voltage returns, it will start to charge the battery, but it will still operate.
• In case of low consumption, it charges the battery more slowly and gently.
• If there is a stable mains voltage for a period of time, it switches from battery to battery and charges the battery. This protects the operated equipment.
• In the case of motorized equipment (refrigerator, fan, pump, hair dryer, etc.), multiple oversizing may be necessary.
• Motors require a high current for a short time when they are started.
• Motorized equipment can operate more quietly, more evenly, and more efficiently with pure sine wave voltage converters.
• Pure sine wave converters draw more current than cheaper modified sine wave inverters.
• Therefore, they require a larger capacity battery and more careful operation.
• When used in a vehicle, continuous operation cannot be guaranteed in the case of vehicles with a smaller generator and a smaller battery, or it may require continuous charging of the battery.
• The recommended battery has a capacity of at least 150Ah.
• This can also be achieved by connecting several 12V batteries in parallel.
• Note that the available continuous output power is less than the rated power and its exact value depends on a myriad of external conditions.
• (type of consumer, characteristics and condition of the battery, external temperature, ensuring adequate cooling, etc.).

Pure sinusoidal wave
It is recommended for all devices, especially the sensitive ones:

• LED TV
• brushless motors
• washing machines
• sewing machines
• laser printers
• copiers
• thyristor-driven and SCR-controlled products
• fluorescent light sources with electronic ballast
• some digital watches
• microprocessor controlled equipment
• some chargers for hand tools and laptops
• inverter equipment
• control electronics…

CHECKING THE OUTPUT VOLTAGE
The signal shape of the supply voltage produced by the inverter is perfect sine wave. You can obtain accurate measurement results with any standard Voltmeter.

Modified sine wave
It is not ideal for all devices; usually usable:

• simple devices
• less sensitive audio devices
• old CRT televisions
• carbon brush motors
• digital watches, battery chargers depending on the model
• large motors can consume up to 30% more energy
• properly functioning devices may become hotter and their service life may shorten
• some audio devices and fans may work noisier

CHECKING THE OUTPUT VOLTAGE
The signal shape of the supply voltage produced by the inverter is modified sine wave. You can obtain accurate measurement results using a TRUE RMS Voltmeter only. Any other instrument type can measure up to 20-30 Volts less than the actual value.

STARTUP

1. Fix the inverter on a horizontal, stable surface, in a well-ventilated, dry place! It must not be exposed to sunlight or heat from other sources of heat. Do not operate near flammable gases or substances!
2. Unscrew and remove the plastic screws of the red (burgundy) and black connectors on the back of the device, then fix the ends of the accessory cables with them. For perfect contact, tighten the screws by hand, but firmly! Only the cable matching the color of the connector may be connected to it! If the ring connector is naturally oxidized, remove the oxide layer.
3. The ring connectors at the other end of the cables must be connected to the positive and negative poles of the battery. Connect the black cable (-) first. In some cases, it may be necessary to obtain the correct battery connector. For good contact, the connection should be tight.
4. Connect the network equipment you want to operate (switched off) to the protective contact socket on the front panel. Make sure not to exceed the permitted rated power!
5. Start the vehicle’s engine so that the alternator charges the battery. If using in a building, connect the included mains connection cable to the rear AC INPUT socket and the 230V~ mains. This ensures that the battery is charged.
6. Switch on the inverter with the rocker switch on the front side: ON ( I ).
7. Turn on the network equipment you want to operate if the green INVERTER LED lights up. If you connect several devices, turn them on one after the other.
8. After use, the mains equipment must be switched off first and only then the inverter (OFF position). Remove the connection cables!

INVERTER LED: the green color indicates normal operation, the red color indicates the activation of the protection circuit.
CHARGE LED: the green color indicates that the built-in battery charger has charged the connected battery.
OVERLOAD SWITCH: the push button on the back must be pressed when the overload protection has been activated.

Make sure to observe the indicated polarity and secure, perfect contact! The device may only be operated with the supplied connection cable. It is forbidden to modify or extend it! The battery should be placed as close as possible and connected with the shortest cable to the inverter. Toxic and flammable gases can escape from the battery, so it can only be used in a well- ventilated area. The high-power circuits in the device can continuously emit sound.

DIGITAL DISPLAYS
The two displays provide a great help for correct, error-free use of the device. The one on the left shows the battery voltage (input DC voltage, BATTERY VOLTAGE). When the charger is put into operation, the charging voltage may change the value. The display on the right shows the output AC voltage (VOLTAGE OUTPUT). The condition of the battery and the magnitude of the output voltage and possible fluctuations due to the load can be continuously checked.

USB SOCKET
You can connect portable devices to the front USB socket, up to its maximum load capacity: 5 V / 2.5 A .

THE BUILT-IN BATTERY CHARGER

The 230 V connector on the back ensures the operation of the battery charger. It has three automatic charging modes that work depending on the current state of the battery: constant current charging, constant voltage charging and maintenance charging to reach 100% capacity. Thanks to this, the battery is always ready for use and its service life will be longer. The bridging time depends on the current power demand of the consumers, the state and temperature of the battery, the ambient temperature and the cooling and ventilation of the voltage converter.
Attention! If acid has leaked from the battery, wear protective gloves and clean the dirty surface with a dry cloth!

• This product can be used to charge a lead-acid battery.
• Read the warnings of the manufacturer of the battery you want to charge so as not to damage it! Do not charge a frozen battery!
• Can only be used in a well-ventilated area! During charging, the battery may heat up and emit toxic and explosive gases. This is a natural phenomenon. Ventilate, do not inhale, do not stay in the immediate vicinity! The use of sparks and open flames, as well as smoking, is prohibited!
• Attention! Danger of explosion!
• Do not cover the device, ensure free air flow when placing it! Covering it can cause overheating, risk of fire, or electric shock!
• A possible short circuit of the battery poles is a risk of fire, explosion and electric shock!
• It is forbidden for children to stay near the battery!
• Risk of explosion! Do not charge non-chargeable batteries!
• When using the mains connector, the battery must not be connected to the vehicle’s circuit!
• When routing the connection cables, make sure that their insulation can not get damaged!
• Do not use if any of the connection cables are damaged!

EXTENSION OF CABLES
A longer or thinner cable has a higher resistance. It is forbidden to extend the 12 Volt connection cable due to the power loss associated with the increasing voltage drop due to the increasing resistance. Instead, a 3 x 1.5 mm2 extension cable can be used to lead the mains voltage from the inverter to the remote device to be operated.

PROTECTION CIRCUITS

The device is equipped with multiple protections; with protection against overload, overheating, short circuit, overvoltage and battery exhaustion. When it starts working, the output voltage is removed. Then immediately

1. Switch off the operated equipment.
2. Turn off the inverter.
3. Unplug the connectors.
4. Check the power requirement of the network equipment to be operated and the correct connection.
5. Check the battery charge status.
6. Check for possible overheating of the inverter.
7. After eliminating the error, use the equipment again. Consult a professional if necessary.

The voltage converter can be operated in a specific voltage range of the battery (approx. 11 V – 14 V). If the voltage is lower or higher than this, the protection is activated, then the red LED lights up and the output is switched off. If the situation returns to normal, the output becomes active again. If the protection is activated due to overload, overheating, etc. occurs due to, then after the problem has been eliminated (e.g. the device cools down) it switches back on. If the warning sound has sounded in the meantime, it will now turn off. Depending on the cause of the error, the rear protection switch may also be activated. It must then be pressed in before further use.

Notes:
In addition to the prescribed voltage range, an adequate amount of current must also be provided, with a charged battery in good condition. The approximate value of the required input current is obtained by dividing the power of the equipment to be operated by 10. For example: 100W/10=10A. If the battery is discharged, the operated equipment and the inverter must be switched off. The vehicle engine must be started to start charging or a battery charger must be connected to it. The frequency or continuity of charging depends on the current conditions of use. From the charge and condition of the battery, the external temperature, the characteristics of the inverter and the nature and consumption of the equipment operated from it.

The power consumption of many household appliances is lower than what can be provided by the inverter, but the overload protection can still be activated when they are switched on. It can most easily operate resistive loads and devices with a switching power supply. These represent a linear, even load. For example, the traditional hob, kettle or LCD TV and other similar equipment. Some audio-video devices and electric hand tools are more demanding. For example, an asynchronous motor, a compressor, a CRT television, a water pump, a pump, a microwave oven, a refrigerator… When they are switched on, they draw much more current than the nominal for a short time. They can have up to 2…6 times the power requirement. In the case of refrigerators, this can be a x10 power requirement. It may be necessary to select a sufficiently high-performance inverter by testing. Especially in the case of motorized devices, multiple oversizing of the inverter is necessary.
The inverters only bear their maximum load for a very short time before the protection shuts them down. The rated load capacity is usually half of this. The continuously guaranteed performance is slightly lower than this and depends to a large extent on external factors. For example, from the temperature of the inverter, the ambient temperature, the placement of the device, the efficiency of the cooling, the nature of the equipment operated, the duration, etc.
The voltage converter switches off automatically in case of overload. It must be ensured that the warm air can escape freely at the cooling fan at the back!

• The green INVERTER LED indicates that it is switched on and ready for operation.
• The red INVERTER LED warns of the activation of the protection. The output is then switched off. Find the cause of the error; for example, the battery voltage is too high or too low, or the output of the inverter is overloaded or a short circuit or overheating has occurred. If necessary, press the OVERLOAD button on the back to reset.
• After the error has been rectified, the inverter can continue to be used.

PROVIDING PROTECTIVE GROUNDING
Before starting to use the inverter, protective earthing must be provided, similar to the case in households.

• For stationary use:
  The special screw on the device must be grounded in such a way that it is connected to a metal rod with a good contact, inserted into the ground at least 1.2 m deep, with a wire with a cross-section of at least 4-6 mm2.

• For use in a vehicle:
  The grounding must be connected to the negative grounding (body) of the vehicle. (Only if the vehicle has a negative grounding.) In case of a vehicle having a positive grounding, the positive (red) pole must be connected. If the operated network equipment is not located in the vehicle, then the grounding rod mentioned above must be used. In a boat, it must be connected to the ground wire of the electrical circuits (e.g. engine) in it.
