INTRODUTION

Thank you for choosing this Modified Sine Wave Inverter. This inverter is capable of converting DC power input to AC power output that has similar output signal wave as normal domestic mains. Unlike pure sine wave inverters, modified sine wave inverter is not recommended for powering voltage sensitive or inductive equipment. For inductive load such as fluorescent light, acoustic equipment and equipment contain motor such as fan and compressor, we recommend to use our pure sine wave inverter instead. Below shows the differences in output voltage waveform between pure and modified output:

PRODUCT LAYOUT:

FRONT PANEL:

• ON/OFF SWITCH – rocker switch to switch unit on and off
• POWER INDICATOR – solid green LED indicates unit has been switched on
• FAULT INDICATOR – solid on or flashing red LED indicates fault has occurred, refer to fault code for interpretation
• USB POWER SOCKET – 5V 1.0A USB power supply socket for charging smart phone camera etc
• UK AC MAINS SOCKET – output UK mains socket provide 230Vac 50Hz mains power
• GROUND CONNECTION – star washer and nut for ground connection to the outer case (normally connected to the vehicle chassis)

BACK PANEL:

• INPUT BATTERY NEGATIVE CONNECTION – battery input connection to connect negative output of the DC power source
• INPUT BATTERY POSITIVE CONNECTION – battery input connection to connect positive output of the DC power source
• FUSES – location of the fuses
• FAN DUCT –fan for cooling – do not obstruct

Temperature and load controlled multi-speed cooling fan:
The cooling fan is designed to run at a speed in proportion to the load, this minimises the running noise and extend fan life.

• At load lower than 40% or inner temperature less than 30°C the fan will not operate
• At load between 40% – 60% the fan will operate at 40% of its maximum speed
• At load between 60% – 80% the fan will operate at 60% of its maximum speed
• At load between 80% – 100% the fan will operate at 80% of its maximum speed
• At 100% load or inner temperature exceeds 45°C the fan will operate at 100% of its maximum speed

INSTALLATION

Location – it is important to for the location of the inverter to meet below requirements:

• Dry environment where there should be no risk of the inverter coming into contact with water
• A cool shaded environment where temperature should be 0°C – 40°C, not to be placed near any heat source and avoid direct sunlight
• A well-ventilated area, minimum clearance of two inches should be allowed in front of the ventilation duct and fan. Please ensure free flow of air around the unit, if the unit is used to its full load, an external fan may be used to aid the cooling of the unit
• Not to be place in the same compartment as the battery or together with flammable substances
• Avoid dusty environments, dust can cause blockage of airflow within the inverter and cause the unit to overheat
• Avoid using long input cable run as input voltage can be affected by cable resistance and heat

Mounting The unit should be mounted horizontally, we do not recommend mounting the unit vertically.

Connection

• Please ensure the ON/OFF switch on the inverter is in the OFF position and the voltage of power source matches the required inverter input voltage, if the power source is from a DC power supply please ensure it is switched off also

• Connect the invert to battery / DC power source. Using provided black cable; connect the
  black negative terminal to the negative output of the power source. Using provided red cable; connect the red positive terminal to the positive output of the power source.

• Before connect the inverter to appliances please ensure the appliance power rating is within the inverter’s continuous output power. After connected, double check all connections are correct before switch on the inverter and appliance. If more than one appliance is being used on the same inverter, please ensure appliances are switched on one after the other, after the inverter has been switched on. This is to avoid the inverter undergoing any surge current from individual load all at once.

Please beware, any use of cables and accessories other than the ones provided may cause damage, Mercury will not take any responsible for damage caused by use of third party accessories. For cable cross-section requirement for different models, please refer to accessory appendix at the back of this manual. Some models with higher power may have 2 pairs of terminals that require 2 pairs of cable to help with the high input current. ALWAYS ensure the correct polarity is connected before start, DO NOT reverse input polarity as it will blow up the fuse and may cause permanent damage to the inverter.

Input power specification:
For an inverter running from a battery, the duration of the appliance is determined by these 3 factors:

• Voltage of input power
• Power of the appliance
• Capacity of the battery

For example an appliance of 100W running on a 12V input power inverter will require:
100/12 = 8.33 Amp/hour
A typical 12V car battery has capacity of around 80Ah; to run the above example on this battery we can estimate it will be capable of duration of:
80/8.33 = 9.6 hours
In reality, this number will be lower due to the power lost from the efficiency in power conversion (in this case over 80% of DC power will be used to convert to AC power) power lost from the input/output cable, depreciation of battery capacity on older batteries, and temperature (a cold battery holds less capacity).

For running the inverter on a DC power supply, it is important the check the current from power source is sufficient to run the inverter at full load. The required current to allow the inverter to operate at full load can be estimated from the continuous output power of the inverter and input power voltage. For example a 1500W 12V input inverter at maximum load will require input current of:
1500 / 12 = 125 Amp
In reality the current requirement will be higher to compensate the power lost during the DC – AC conversion and the power lost from the cable.
From the above calculation please choose your power source set up for the inverter carefully to suit the purpose of use in terms of both duration and load.
The start-up load is also a major factor of whether the inverter is capable to power up the appliance. Although the start-up load peaks for a fraction of a second, the start-up load is normally twice as much as the rated continuous power of the appliance. In some equipment the start-up load can be as high as 8 times of its continuous power, especially on inductive loads that include an electric motor.
This inverter can withstand the momentary start-up load for up to 2 times of its rated continuous output power for up to 2 seconds. To determine if the inverter is capable to start up an appliance, simply test it by plugging it in and running it. If the start-up current peaks higher than the highest power inverter can supply, it will trigger the over load protection, which creates a buzz and the fault LED indicator will light to indicate there is a fault.

BATTERY ARRAY CONNECTION

To increase the duration of inverter operation while running on battery, multiple batteries can be linked together to increase the total capacity and duration. The below diagram shows the common ways to wire typical 12V 75Ah batteries together to increase the capacity for both 12V and 24V output:
12V OUTPUT – PARALLEL CONNECTION (voltage remains current increase)

24V OUTPUT – SERIES CONNECTION (voltage increase current remain)

24V OUTPUT – SERIES/PARALLEL CONNECTION (both voltage and current increase )

SAFETY INSTRUCTION

Please note the following instructions should be carefully followed as any incorrect installation or misuse of the inverter may cause harm to user and damage apparatus.

• Do not connect any other form of input power other than DC power that is within the inverter’s acceptance range
• Ensure the ventilation duct on both front and back panels are clear of blockage when the inverter is in use
• Please use appliance with power rated within the inverter power range.
• Do not attempt to overload the inverter constantly
• Do not pull on cable when unplugging from the inverter, always grip firmly on the plug
• To avoid shock hazard, always ensure inverter and DC power supply (if apply) are switched off before inserting the AC plug to the inverter
• Strictly for indoor use only, avoid exposing the unit to any heat source, sunlight, dust, moisture or flammable substances
• It is normal that the inverter will become hot while in use, please avoid touching the unit
• Do not drop the inverter
• Do not place any object on the inverter
• Always connect/set up with cable and accessories supplied and follow the instructions carefully. Any use of third party accessories may cause damage and result in injury
• Do not attempt to service or disassemble the inverter. Any attempt to do so can cause injury to user including death from exposure to high voltage. If problems are experienced from the unit when in use, please discontinue use immediately and contact technician or retailer
• This inverter is design to be maintenance free, but requires occasional attention as dust may build up after period of time. To clean dust off, please switch off power from inverter and unplug AC plug. Carefully clean unit with a dry cloth. Do not use a wet cloth or cleaner
• Check and tighten the DC input terminal on regular basis, as if the inverter is stored in an environment with a lot of vibration (eg in a vehicle) it may cause the hand screw to become loose
• Keep out of reach of children

INTERFERENCE

It is not suggested to use modified sine wave inverter to power acoustic equipment. As the modified sine wave power signal will induce distortion signal to the sound signal within equipment if circuitry is not well
isolated. This will cause a continuous “hum” or “buzz” background noise.
Also inverter may cause interference to TV signals. The interference can be minimising by adding an inline aerial filter between the TV and TV antenna. If the interference become obvious especially in weak signal areas, please try to place the inverter as far away from the antenna as possible and use high quality screened coax cable.
