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:

-
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
User Manual
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).
User Manual
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)
User Manual
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.
-

User Manual
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.
WARRANTY
All inverters are covered against defects in components and build quality for period of up to 12 months
from the day of purchase. Valid receipt or bank statement to show purchase date is within last 12 months
must be shown for warranty to be valid.
Any unit that has been misused, altered or accidentally damaged will not be covered by warranty.
