1. Introduction
Thank you for purchasing this power inverter. This simple power inverter is designed to power your home
appliances or precious 3C electronics. It also can handle motor-type loads with high surge power such as
vacuums, small freezers, or drills. With built-in AC charger, it can convert utility power to battery power and
provide continuous power to connected equipment during power failure.
2. Important Safety Warning (SAVE THESE INSTRUCTIONS)
Before using the inverter, please read all instructions and cautionary markings on the unit, this
manual and the batteries.
General Precaution-
CAUTION! The unit is designed for indoor use. Do not expose this unit to rain, snow or liquids of any type.
CAUTION! To reduce 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! It's very important for system safety and efficient operation to use appropriate external battery
cable. To reduce risk of injury, external battery cables should be UL certified and rated for 105°C or higher. And
do not use copper cables less than 6AWG or 10AWG*2.
CAUTION! Do not disassemble the inverter. Contact with the qualified service center 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-circuit when installing or working with the inverter,
the batteries, or other equipments 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 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 accident during servicing.
Conventions used:
WARNING! Warnings identify conditions or practices that could result in personal injury;
CAUTION! Caution identify conditions or practices that could result in damaged to the unit or other
equipment connected.

4. Installation
NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is damaged.
Mounting the unit
The unit ONLY can be mounted vertically to a wall surface.
Please follow below steps:
1. Turn off the unit before mounting.
2. Select an appropriate mounting location. Mark four mounted ends as shown in chart.
3. Drill four marks by screws.
4. Mount the unit by positioning the key-hole slots over the mounting screws.
Connect External Battery
Step 1- Install a DC Breaker in a positive battery line. The rating of the DC Breaker must be according to the
inverter's battery current (100 Amp). Keep the DC breaker off.
Step 2 - Remove insulation sleeve 18 mm for positive and negative conductors.
Step 3- Connect battery cables to the external batteries.
Note: For the user operation safety, we strongly recommend that you should use tapes to isolate the battery
terminals before you start to operate the unit.
1) Single battery connection: When using a single battery, its voltage must be equal to the Nominal DC
Voltage of the unit
2) Multiple batteries in series connection(Refer to Fig. 3): All batteries must be equal in voltage and
amp hour capacity. The sum of their voltages must be equal to the nominal DC Voltage of the unit.

Step 4- Make sure to connect the polarity of battery side and the unit correctly.
Positive pole (Red) of battery to the positive terminal (+) of the unit.
Negative pole (Black) of battery to the negative terminal (-) of the unit.
Step 5-Take the DC breaker on.
5. Operation
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 press the power
switch again, the unit will be turned off.
