• Communication cable 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:

• 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.
• 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 right diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.

SUITABLE FOR MOUNTING ON CONCRETE OR Lil. OTHER NON-COMBUSTIBLE SURFACE ONLY.

Install the unit by screwing two 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.

Recommended battery cable and terminal size:

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.
   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 spec of AC breaker is for 32A for 3.SKW ,S0A for 5.SKW.

• 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

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)
   • LINE (brown or black)
   • 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)
   • LINE (brown or black)
   • Neutral (blue)

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: Applances such as air conditioner are required at least 23 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 manutacturer of air conditioner if its equipped with time-delay function before insta|lation. Otherwise, ths inverter/charger will trig overload faut 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.

Take 250Wp PV module as an example. After considering above two parameters, the recommended module Confiqurations are listed as below table.

Please follow below steps to implement PV module connection:

1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Check correct polarity of connection cable from PV modules and PV input connectors. Then, connect positive pole (+) of connection cable to positive pole (+) of PV input connector. Connect negative pole (-) of connection cable to negative pole (-) of P\V input connector.
3. Make sure the wires are securely connected.

Final Assembly

After connecting all wirings, please put bottom cover back by screwing two screws as shown below.

Operating Mode Description

Battery Equalization Description

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.

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 arived.

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 .
