1.2KVA/ 2.4KVA Inverter
V. 1.1
1. Introduction
Thank you for purchasing the solar 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. With built-in solar charger, it can
convert solar power to battery power and provide continuous power to connected equipment
during night time.
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-
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- Take away the cover of external battery terminal.
Step 2- Following battery polarity guide printed near the battery terminal!
Place the external battery cable ring terminal over the battery terminal.
RED cable to the positive terminal (+);
BLACK cable to the negative terminal (-).
WARNING! Please use the appropriate battery cable. Please refer to Important Safety
Warnings Section for the details.
Step 3- Tight the battery cables with the M5 nuts. Do NOT place anything between the flat
part of battery terminal and the battery cable ring terminal, or overheating may occur.
(See Fig. 1)
Step 4- Install a DC Breaker in a positive battery line. The
rating of the DC Breaker must be according to the inverter's
battery current (75 Amp). Keep the DC breaker off. (see Fig. 2)
Step 5- 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(Refer to Fig. 2): When using a single battery, its voltage
must be equal to the Nominal DC Voltage of the unit (see below Table 1).
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.
Fig 3
3) Multiple batteries in parallel connection(Refer to Fig. 4): Each battery's voltage
must be equal to the Nominal DC Voltage of the unit.
Fig 4
Step 6- 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 7- Put the covers back to the external battery terminals.
Step 8- Take the DC breaker on.

Connect to Solar Panel
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker
between inverter and PV modules.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use appropriate
cable for PV module connection. To reduce risk of injury, please use the proper
recommended cable size as 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 LED lights up, it means that batteries are
charged by solar power. When the batteries are fully charged or there is no solar power
available, the LED will be off. (See following chart)

Operation Mode Selector
a). “UPS”: setting for conventional electrical appliance.
If you select this mode, the unit's input utility range will be 170~280VAC as normal home UPS.
If the utility is higher or lower than this range, the unit will transfer to inverter mode
automatically. And you can connect the computer systems or other precision home
equipment when you select this operation mode.
b). “INV.”: setting for energy saving
If you select this mode, the unit's input utility range will be extended to 90~280VAC. If the
utility is higher or lower than this range, the unit will transfer to inverter mode automatically.
So, you can connect the home equipments, such as light bulb, fluorescent tube, fan, or TV
on this mode.
Caution!! If you select the “INV.” mode and connect the computer to the output of the unit,
the computer may reboot if the input voltage is too low to be accepted.
