INVERTER

This compact inverter is designed to power your home appliances and electronics. Its
compact size means this product is easy to install and highly mobile. Compared with
traditional inverters, this inverter provides two operation modes: Narrow and wide.
When selected in either of these modes, the switch will monitor the incoming voltage
and switch automatically to external power should the voltage drop or go higher than
the specified range of the chosen mode. This is highly beneficial to solutions and
appliances which require stable and uninterrupted power during periods of blackouts
and inconsistent power supply. 100AH batteries are recommended to be used with the
selectable 10/20A charge current for efficient charging.

Before using this inverter, please read all the instruction and
cautionary markings on the unit, in this manual and on the batteries.
Caution identifies conditions or practices that could result in damage to
either the unit or the connected equipment.
CAUTION! This unit is designed for indoor use only. Do not expose the unit to
rain, snow or any other liquids and direct sun light.
CAUTION! To reduce risk of injuries, only use qualified batteries from qualified
distributors and/or manufacturers. Any unqualified batteries may cause potential
damages and injuries. Do N OT use old, overdue or damaged batteries. Please
check the battery type, date and condition before installation and use to avoid any
potential damages and injuries.
WARNIN G! It's very important for efficient operation and system safety that
appropriate external battery cable are used. To reduce risk of potential injuries,
external battery cables should be UL certified and rated for 75°C or higher. Do not
use copper cables with higher AWG than 10AWG. Below is the external battery
cable reference according to system requirements.

CAUTION! Do not disassemble the inverter. Contact a qualified service center
when service or repair is required.
WARNING! Provide sufficient ventilation for the battery compartment. The

concentration of hydrogen gas at the top of the compartment.
CAUTION! Use insulated tools and cables to reduce the risk of short circuit's
when installing or working with the inverter, the batteries, or any other equipment
connected to this unit.
CAUTION! For battery installation and maintenance, please read the battery's
installation and maintenance instructions prior to operating and/or installation.
Personnel Precaution -
CAUTION! Be careful and avoid dropping a metal tool on the batteries, it could
spark or short circuit the batteries leading to fire hazards or other damages to
the batteries.
C A U T I O N ! Remove all personal metal items such as rings, bracelets,
necklaces, and watches when working with the batteries as they can produce a
short circuit current high enough to melt metal leading to severe burns.
CAUTION! Avoid touching your eyes while working near batteries as there can
be potential hazardous chemicals on or leaking from the batteries.
CAUTION! Ensure access to sufficient fresh water and soap in case battery acid
encounters skin, clothes or eyes.
CAUTION! NEVER smoke or allow a spark or flame to appear in vicinity of
batteries.
CAUTION! If a remote or automatic generator start system is being used,
disable the automatic starting circuit or disconnect the generator to prevent
accidents from happening during any servicing.

NOTE: Before installation, please inspect the unit, to ensure that nothing
inside the package is damaged and/or missing.
Connect to Utility Power and Charge
Plug the AC input cord into the wall outlet. The unit will automatically start
charging any connected external batteries even though the unit is switched off.
Single Battery Connection Voltage (Refer to Fig 1):
When using any batteries, the voltage must be equal to the Nominal DC
Voltage of the unit (see below Table 1).
Mounting the Unit
The unit can be mounted onto a wall surface by following the below steps:
1. Turn off and disconnect the unit before attempting to mount the unit.
2. After selecting an appropriate mounting location, use a horizontal line with a
length of 205 mm and mark the ends of the line on the wall. (See chart 1)
3. Drill and insert two mounting screws at these marks, one each.
4. Mount the unit by positioning the key-hole slots over the mounting screws and
sliding the unit till securely attached.

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

5.Battery level (Battery capacity)

7.Load level (Load percentage used)
8.Overload (when the load exceeds max load capacity, this LC D symbol will be
flashing)
9.Fault mode(this LCD symbol will be lit when inverter is in fault mode, such as a
short circuit or system overload)
Narrow Mode: 162 V to 280 V, the unit will not switch over to battery backup if utility
power is available and the utility voltage is higher than 162 V and lower than 280 V.
Wide Mode: 90 V to 280 V, the unit will not switch over to battery backup if utility
power is available and the voltage is higher than 90 V and lower than 280 V.
a). "Narrow": setting for conventional electrical appliances such as computers, TVs etc.
as narrow mode reduces the switch over time from utility to battery backup.
b). "Wide: setting for energy saving, with lower line sensitivity and longer switch over
times during power failures.
10/20A: The maximum charging current determines the recommended battery capacity
which can be connected to the unit as it will effect charging time periods required to fully
recharge the connected batteries for example the 10A current is recommended for
100AH or lower batteries.

Use the below table to solve common errors/problem:
When utility power is
available and within the
selected operating
range, yet the unit in
inverter mode.
AC input cord might not be
properly connected.
Input breaker switch might be
activated.
Secure and properly connect the
AC input cord.
Reset the input breaker switch.
When the power fails
the backup time is
shorter than
previously.
The unit might be overloaded.
Battery voltage might be too
low.
Battery capacity might not be
full even after 8+ hours of
charging.
Remove non-critical loads.
Let the unit charge for a
sufficient time period.
Check the date and condition
of the batteries, replace if
needed.
LCD display is dark
whilst utility power is
available and within
selected range.
The inverter might be
switched off.
The battery might not be
properly connected.
There might be defects/
faults in the battery.
Battery voltage might be too
low.
Press the power switch to power
on the unit.
Check the battery connection
and secure all connections.
Replace the batteries.
Let the unit charge for a
sufficient time period.
The unit is constantly
in fault mode and
restarts frequently.
The unit might be overloaded.
The output might be short
circuited.
Verify that the load does not
exceed the max load capacity of
the inverter.
Check the connected loads and
disconnect/resolve the
connected load causing the
short circuit.
