Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have
received the following items inside of package:
The unit x 1
User manual x 1
USB cable x 1
Software CD x 1
BTS Line x 1(Option)
WIFI Key x 1(Option)
Remote Line x 1(Option)
Preparation
Before connecting all wirings, please take off bottom cover by removing six screws as shown below.
Do not mount the inverter on flammable construction materials.
Mount on a solid surface.
Install this inverter at eye level in order to allow the LCD display
to be read at all times.
For proper air circulation to dissipate heat, allow a clearance of
approx. 50cm to the side and 80 cm above and below the unit.
o o
The ambient temperature should be between 0 c and 40 c to
ensure optimal operation.
The recommended installation position is to be adhered to the
wall vertically.
Be sure to keep other objects and surfaces as shown in the
diagram to guarantee sufficient heat dissipation and to have
enough space for removing wires
SUITABLE FOR MOUNTING ON CONCRETE OROTHER

Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
Install the unit by screwing six screws
Battery Connection
CAUTION: For safety operation and regulation compliance, it's requested to install a separate DC over-current
protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device in
some applications, however, it's still requested to have over-current protection installed. Please refer to typical
amperage in below table as required fuse or breaker size.
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 battery connection. To reduce risk of injury, please use the
proper recommended cable and terminal size as below.

NOTE: Please only use sealed lead acid battery or sealed GEL/AGM lead-acid battery.
3. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are
tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and ring terminals are tightly screwed to the battery terminals.

WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring terminal.
Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected tightly.
CAUTION!!Before making the final DC connection or closing DC breaker/disconnector, be sure positive
(+) must be connected to positive (+) and negative (-) must be connected to negative (-).
AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and
AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully
protected from over current of AC input. The recommended appropriate of AC breaker is 40A for 4KW-6KW, 80A for
8KW-12KW.
CAUTION!! Please don't connect the output wring to "INPUT" terminal or connect the grid wring to the "OUTPUT"
terminal.
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 AC input
connection. To reduce risk of injury, please use the proper recommended cable size as below.

Please follow below steps to implement AC input/output connection:
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be sure
to connect PE protective conductor ( ) first.

Be sure to that AC power source is disconnected before attempting to hardwire it to the unit.
4. Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.

5. Make sure the wires are securely connected.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility
short-circuited when these inverters are worked in parallel operation.
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it's required to
have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short
time, it will cause damage to your connected appliances. To prevent this kind of damage, please check manufacturer
of air conditioner if it's equipped with time-delay function before installation. Otherwise, this inverter/charger will
trig overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the
air conditioner.
