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
Preparation
Before connecting all wires, please
Remove two screws as shown below.
Mounting the Unit
Consider the following points before selecting where to install:
1. Do not mount the inverter on flammable construction materials.
2. Mount on a solid surface.
3. Install this inverter at eye level in order to allow the LCD display
to be read at all times.
4. For proper air circulation to dissipate heat, allow a clearance of
approx. 200 mm to the side and approx. 300 mm above and below
the unit.
5. The ambient temperature should be between 0c and 55℃to
ensure optimal operation.
6. The recommended installation position is to be adhered to
the wall vertically.
7. 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.

5
SUITABLE FOR MOUNTING ON CONCRETE OROTHER
NON-COMBUSTIBLE SURFACE ONLY.
Install the unit by screwing four 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 is 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.
WARNINGI 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.

Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. Connect all battery packs as units requires. It's suggested to connect at least 200Ah capacity battery for 3kW~5kW
model.
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.

7
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/dis-connector; 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 spec of AC breaker is 32A for 3kW and 50A for 5kW.
CAUTION!! There are two terminal blocks with "IN" and "OUT" markings. Please do not invert input and output
connectors.
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,
lb 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 dis-connector 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.

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 is 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 is 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.
PV Connection
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.

PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.
3. Max. Power Voltage (Vmpp) of PV modules should be close to best Vmp of inverter or within Vmp range to get best
performance. If one PV module can not meet this requirement, it's necessary to have several PV modules in series

9
connection. Refer to below table.
Note:* Vmp: panel max power point voltage.
The PV charging efficiency is maximized while PV system voltage is close to Best Vmp.
Maximum PV module numbers in Series: Vmpp of PV module*X pcs = Best Vmp of Inverter or Vmp range
