1. Introduction
Thank you for purchasing the inverter. This simple solar 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. If the inverter is equipped with solar
charger, it becomes solar inverter which can convert solar power to battery power and provide
continuous power to connected equipment during night time.

3. 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-
Install the UPS in a protected area that is free of excessive dust and has adequate air flow.
Please place the UPS away from other units at least 20 cm to avoid interference. Do NOT
operate the UPS where the temperature and humidity is outside the specific limits. (Please
check the specs for the limitations.)
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 75°C or higher. And do not use copper cables less than 10AWG. Below is the
external battery cable reference according to system requirements.

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.

5. Installation
NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is
damaged.
Connect to Utility and Charge
Plug in the AC input cord to the wall outlet. The unit will automatically charge the connected
external battery even though the unit is off.
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 (50 Amp). Keep the DC breaker off. (see Fig. 1)
Step 2- Connect battery cables to the terminals of battery.
WARNING! Please use the appropriate battery cable. Please refer to Important Safety
Warnings Section for the details.
1) Single battery connection (Refer to Fig. 1): When using a single battery, its voltage
must be equal to the Nominal DC Voltage of the unit (see below Table 1).
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.

Fig. 1
2) Multiple batteries in series connection (Refer to Fig. 2): 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.
Fig 2
3) Multiple batteries in parallel connection (Refer to Fig. 3): Each battery's voltage
must be equal to the Nominal DC Voltage of the unit.

Step 3- 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 4- Put the covers back to the external battery terminals.
Step 5- Take the DC breaker on.
Connect to Utility and Charge
Plug in the AC input cord to the wall outlet. The unit will automatically charge the connected
external battery even though the unit is off.
Connect to Device
Simply plug devices to battery supplied sockets. During power failure, it will provide continuous
power to connected devices.
Connect to Solar Panel (only for the model is equipped with solar charger)
To prevent any damage to the solar charger, please DO select the solar panel and battery
capacity according to recommended specifications below.

Step 1- Connect one cable to the positive(+) pole of solar panel and solar charger positive
(+) terminal.
Step 2- Connect the other cable to the negative (-) pole of solar panel and solar charger
negative (-) terminal.
Step 3- Check the solar charging indicator. If the green LED flashes, it means that batteries
are charged by solar power. When the batteries are fully charged, the green LED will be
lighting. If there is no solar power available, the green LED will be off. If any fault occurs on
charger, the red LED will light up. (See following chart)
