2.4KVA Inverter User Manual

The Mercury Inverter 2.4kva User Manual will help you familiarise yourself with all of the features of the Mercury 2.4kva inverter and the correct installation procedure.

The Mercury Inverter 2.4kva is compact and designed to power your home appliances and precious electronics.   Its compact size enables easy installation and high movability.  Compared with traditional inverters in the market, this inverter provides two operation modes: UPS mode and Inverter mode.   On UPS mode, the inverter can provide continuous power to general home appliances.   At Inverter mode, the inverter can provide continuous power to bulb and fan loads.

The inverter has two charging modes:10A and 20A, select 10A mode when connecting to battery sizes 100AH  and lower, select 20A mode when connecting to  100AH and above.

 Important Safety Warnings

Before using the inverter, please read all instructions and cautionary
markings on the unit, the manual and batteries.

General Precaution-

Conventions used:

WARNING! Warnings identify conditions or practices that could result in personal
injury;

CAUTION! Cautions identify conditions or practices that could result in damage to
the unit or other equipment connected.

CAUTION! The unit is designed for indoor use. Do not expose this unit to rain, snow
or liquids of any type.

CAUTION! To reduce the risk of injury, only use qualified batteries from qualified
distributors or manufacturers. Any unqualified batteries may cause damage and
injury. Do NOT use old or overdue batteries. Please check the battery type and date
code before installation to avoid damage and injury.

WARNING! To connect the inverter to a fuse box engage the services of a qualified electrician, with extensive experience of connecting inverters to NEPA.

WARNING! It’s very important for system safety and efficient operation to use
appropriate external battery cables. To reduce the risk of injury, external battery cables
should be UL certified and rated for 75 C or higher. Do not use copper cables
less than lOAWG. Below is the external battery cable reference according to system
requirements.

CAUTION! Do not disassemble the inverter. Contact a Mercury Service Centre
when service or repair is required.

WARNING! Provide ventilation to outdoors from the battery compartment. The
battery enclosure should be designed to prevent accumulation and concentration of hydrogen gas at the top of the compartment.

CAUTION! Use insulated tools to reduce the chance of short-circuiting when installing or
working with the inverter, the batteries, or other equipment attached to this unit.
CAUTION! For battery installation and maintenance, read the battery manufacturer’s
installation and maintenance instructions prior to operating.

Personnel Precaution –

CAUTION! Careful to reduce the risk or dropping a metal tool on the batteries. It could
spark or short circuit the batteries and could cause an explosion.

CAUTION! Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with batteries. Batteries can produce a short circuit current
high enough to make metal melt and could cause severe burns.

CAUTION! Avoid touching eyes while working near batteries.

CAUTION! Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing, or eyes.

CAUTION! NEVER smoke or allow a spark or flame in the vicinity of a battery.
CAUTION! If a remote or automatic generator start system is used, disable the
automatic starting circuit or disconnect the generator to prevent an accident during
servicing.

Installation

NOTE: Before installation, inspect the unit and be sure that nothing inside the package is damaged.

Step 1

A qualified electrician should create a NEPA only charging socket for the inverter.   The charging socket needs to be NEPA only, so the inverter does not feedback on itself.

Step 2

From the fuse box, a qualified electrician should separate the intended inverter load from the load which will be powered by NEPA only e.g AC, fridge and kitchen sockets.

Step 3

Confirm that the inverter is switched off.  Plug the inverter load into one of the AC output sockets on the back of the inverter.

Step 4

Connect the inverter to an external battery bank

 

WARNING! Please use the appropriate battery cable. Please refer to Important
Safety Warnings Section for the details.

c: – Tight the battery cables with the M5 nuts. Do NOT place anything between the
flat part of the battery terminal and the battery cable ring terminal, or overheating
may occur. (See Fig.1)

Step 5

Plug in the AC input cord to the NEPA only wall outlet. The unit will automatically charge the connected external battery bank even though the unit is off.

 

Mounting the Unit

The unit can be mounted to a wall surface.  Please follow below steps:

  1. Turn off the unit before mounting.
  2. Select an appropriate mounting location.  Use a horizontal line and the length of the line must be 205 mm and mark the two ends of the wall. (see Fig.4)
  3. Drill two marks by screws.
  4. Mount the unit by positioning the key-hole slots over the mounting screw (see Fig.5 )

    Operation

    Mounting Mercury Inverter

    Power On/Off

    Once the inverter has been properly installed, press the power switch to turn on the unit. The unit will work automatically in line mode or inverter mode according to input utility power’s  status. When pressing the power switch again, the unit will be turned off.

     

    1. Input voltage

    2. Output voltage

    3. AC mode (machine in line mode, this LCD symbol lights )

    4. Battery mode (when AC input voltage is abnormal, this LCD symbol lights)

     

    5. Battery level (Battery capability)

    6. Low battery (when battery voltage is low, this LCD symbol flashes)

    7. Load level (Lod percent)

    8. Overload (when there is output overloading,  this LCD symbol flashes)

    9. Fault mode (this LCD symbol will light when the inverter is in fault mode, such as output shorted, overload)

Operation  Mode Selector

a). “UPS “: setting for the conventional electrical appliance.

If you select this mode, the unit’s input utility range is narrow.If the utility is higher

or lower than this range, the unit will transfer to battery mode automatically. And you can connect the general home appliances when you select this operation mode.

b). “INV “: se_tting for energy saving.

If you select this mode, the unit’s input utility range is wide. f the utility is higher or lower than this range, the unit will transfer to inverter mode automatically.  So, you can connect lamp and fan load.

 

Charging Current Mode Selector

  • “10A’: The maximum charging current is 10A, select 10A mode When Connecting Battery 100AH and Lower.
  • “20A’: The maximum charging current is 20A, select 20A mode When Connecting Battery 100AH and Above.

The detailed refer to Table 4 and Table 5.

    1. Try disconnecting and reconnecting the inverter to the battery. If it still displays fault after reconnecting, give us a call on 07037451701 and we will help you resolve the issue.

    1. Try switching off the inverter and unplugging the load plug from the back of the inverter. Unplug the charging cable from the wall. If the buzzer does not stop, even after turning off the inverter, then removing one of the inverter cables from the battery bank for a few seconds should stop the noise. Switch the inverter back on does it still show fault?

  1. My inverter just displace F2 with ⚠ faulty and continuous sound. This only come when trying to load it but if I switch on without loading everything looks Good and fine.

    1. Try unplugging the load plug from the back and plugging a phone charger into one of the sockets on the back of the inverter. Does it power the phone or does it still display F2? If it powers your phone, it means you have an electrical fault. If it still displays F2, please connect the point of sale, so the inverter can be repaired or replaced no question asked if it is still under warranty.
