Specifications
WARNING! Please use the appropriate AC input cable. Please refer to Important Safety
Warnings Section for the details.
Step 3- Screw tightly the AC input power cord.
Connect External Battery
Step 1- Install a DC Breaker in a positive battery line. The rating of the DC Breaker must be at
least 60Amp to guarantee safe operation without interruption. Keep the DC breaker off. (see
Fig. 1)
Step 2- Connect battery cables to the external batteries. To have better performance, the
recommended battery capacity is 100Ah – 200 Ah.
Following battery polarity guide printed near the battery terminal to connect external batteries!
RED cable to the positive terminal (+);
BLACK cable to the negative terminal (-)
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. When connecting to external
batteries, do not cause any short circuits.
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).
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
Note: when connecting batteries in series connection, it’s necessary to use battery wires at #8
or above.
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.
Fig 3
Note: when connecting batteries in parallel connection, it’s necessary to use battery wires at
#10 or above.
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- 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.
6. 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. When press the power switch again, the unit will be turned off.
WARNING! The unit may have output power when connected to the utility, even though it is
powered off. To completely cut off the output power, please switch off the unit and disconnect
the unit from the utility.
Input Voltage Range Selector
a). 180V-260V: setting for precious electronic devices
If you select this mode, the unit's input utility range will be 180~260VAC 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). 100V-300V: setting for home appliances
If you select this mode, the unit's input utility range will be extended to 100~300VAC. 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 home appliance 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.
Charging Current Selector
a) High: setting battery charging current at 20A
b) Low: setting battery charging current at 10A
