4.2 Preparation
Before connecting all wirings, please take off bottom cover by removing two screws as shown below.
4.3 Mounting the Unit

Consider the following points before selecting where to install:
 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. 20 cm to the side and approx. 50
cm above and below the unit.
 The ambient temperature should be between 0°C and 55°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 OR OTHER NON-COMBUSTIBLE SURFACE ONLY.

4.4 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 as below.
If the customer chooses the external battery.

Recommended battery cable size:
2
Model Wire Size Cable (mm ) Torque value（max）
3.2KW/5KW 1 x 2AWG 35 2 Nm
Please follow below steps to implement battery connection:

1. Remove insulation sleeve 18 mm for positive and negative conductors.
2. Suggest to put bootlace ferrules on the end of positive and negative wires
with a proper crimping tool.
3. Fix strain relief plate to the inverter by supplied screws as shown in below
chart.
4. Connect all battery packs as below chart.
5. .Insert the battery wire flat into the DC breaker input side to ensure that the bolt is tightened 2nm clockwise.
Ensure that the polarity between the battery and the inverter / charging is connected correctly, and the wire is
tightly screwed into the DC breaker terminal.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
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
(-).

4.5 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
3.2KVA and 50A for 5KVA.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect 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. To reduce risk of injury, please use the proper recommended cable size as below.
Suggested cable requirement for AC wires
Model Gauge Cable (mm2) Torque Value
3.2KW 12 AWG 4 1.2 Nm
5KW 10 AWG 6 1.2 Nm
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 3 mm.
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.
→Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)
WARNING:
Be sure 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.
Be sure to connect PE protective conductor ( ) first.
→Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)
5. Make sure the wires are securely connected.

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.
4.6 PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
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.
Model Wire Size Cable (mm2) Torque value（max）
3.2KW/5KW 1 x 12AWG 4 1.2 Nm
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.

Equalization function is added into charge controller. It reverses the buildup of negative chemical effects like
stratification, a condition where acid concentration is greater at the bottom of the battery than at the top.
Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this
condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it’s recommended to
equalize battery periodically.
 How to Apply Equalization Function

You must enable battery equalization function in monitoring LCD setting program 30 first. Then, you may apply
this function in device by either one of following methods:
1. Setting equalization interval in program 35.
2. Active equalization immediately in program 36.
29

 When to Equalize
In float stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is
active immediately, the controller will start to enter Equalize stage.
 Equalize charging time and timeout

In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage
raises to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage
at the battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized
time is arrived.
However, in Equalize stage, when battery equalized time is expired and battery voltage doesn’t rise to battery
equalization voltage point, the charge controller will extend the battery equalized time until battery voltage
achieves battery equalization voltage. If battery voltage is still lower than battery equalization voltage when
battery equalized timeout setting is over, the charge controller will stop equalization and return to float stage.
