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.

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
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 po) 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)
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 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.
LCD Indicators & Audible Alarms
There are three indicators (Green/Red/Yellow) in the front panel of the unit.
