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

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 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 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).
