PV. Conection

PV Connection (Only apply for the model with solar charger).

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. 
• 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 requirements first: 
1.Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit 

  voltage of inverter.   

 2. 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 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
PV module numbers in Parallel : Max. charging current of inverter / Impp
Total PV module numbers = maximum PV module numbers in series * PV module numbers in
parallel .

Take 1KVA inverter as an example to select proper PV modules. After considering Voc of PV module not exceeds 50Vdc and max. Vmpp of PV module close to 15Vdc or within 13Vdc ~ 18Vdc, we can choose PV module with below specification.  

 

AC Input/Output Connection

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 10A for 1KVA, 20A for 2KVA, 32A for 3KVA , 40A for 4KVA and 50A for 5KVA. 
• There are two terminal blocks with “IN” and “OUT” markings. Please do NOTmis-connect input and output connectors.
  

WARNING!

• All wiring must be performed by a qualified personnel.    
• It's very important for system safety and efficient operation to use appropriate cable frecommended cable size as below. or 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 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 (ground) first.
4.Then, insert AC output wires according to polarities indicated on terminal block and 
   tighten terminal screws. Be sure to connect PE protective conductor
Ground : (yellow-green).
L/  LINE    : (brown or black) cable
        N/  Neutral : (blue) cable
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. 
• 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 .

 

Battery Connection

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
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. 

Ring terminal:

 Please follow below steps to implement battery connection:
1.Assemble battery ring terminal based on recommended battery cable and terminal size.
2.1KVA model supports 12VDC system, 2KVA/3KVA model supports 24VDC system and  
   4KVA/5KVA model supports 48VDC system. Connect all battery packs as below chart. It’s  
   suggested to connect at least 100Ah.
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.

Inspection (Instalation, Preparation, Mounting Unit)

INSTALATION 

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
Communication cable x 1
Software CD x 1 

Preparation
Before connecting all wirings, please take off bottom cover by removing 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. 20 cm to the side and approx. 50 cm above and below the unit.
5. The ambient temperature should be between 0°C and 55°C 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.

SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY. Install the unit by screwing three screws. It’s recommended to use M4 or M5 screws.
