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).
