4.3 Mounting the Unit

Consider the following points before selecting where to install:

Do not mount the inverter on flammable 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.

Vertical Installation is recommended.

Ensure that the inverter is clear on all sides of objects as indicated. This is in order to guarantee sufficient heat dissipation and to allow for sufficient room to remove wires.

Do not install in the same room as vented batteries.

4.4 Battery Connection

CAUTION:

For safe operation and regulatory compliance, it’s suggested that a separate DC over-current protector or disconnect device be installed between the batteries and the inverter. It may not be required to have a disconnect device in some applications, however, it’s still suggested to have over-current protection installed. Please refer to typical amperage in the table below as required fuse or breaker size.

WARNING!

All wiring must be performed by qualified persons.

WARNING!

It's very important for system safety and efficient operation to use appropriate cables for the battery connection.

Please follow below steps to implement battery connection:

1. Assemble battery ring terminal based on recommended battery cable and terminal size.

2. The 1KVA model supports a 12VDC battery system, the 3KVA model supports a 24VDC battery system and the 5KVA model supports a 48VDC battery system. Connect all batteries as shown in the diagram below. It’s suggested to connect at least a 100Ah capacity battery for the 1 and 3KVA models and at least a 200Ah capacity battery for 5KVA model.

3. Insert the ring terminal of the battery cable flat into the battery connector of the inverter and ensure the bolts are tightened with a 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 voltages.

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.

CAUTION!!

Before making the final DC connection or closing the 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 the AC input power source, install a separate AC breaker between the inverter and the 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 capacity of the AC breaker is 10A for 1KVA, 32A for 3KVA and 50A for 5KVA.

CAUTION!!

There are two terminal blocks with “IN” and “OUT” markings.

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 the risk of injury, please use the recommended cable size as suggested below.

Please follow the steps below to complete AC input/output connection:

1. Before making AC input/output connection, be sure to open

DC protector or disconnector first.

2. Remove 10mm of the insulation sleeve for six conductors.

Shorten phase L and neutral conductor N by 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 (

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 a utility shortcircuit when these inverters are connected in parallel.

CAUTION:

Appliances such as air conditioners require at least 2~3 minutes to restart as it requires sufficient time to balance the refrigerant gas inside the circuits. If a power shortage occurs and recovers in a short time, it may cause damage to your connected appliances. To prevent this, type of damage, please check with the manufacturer of the air conditioner that it is equipped with a time-delay function. Otherwise, this inverter/ charger will trigger an 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 the PV modules, please install a separate

DC circuit breaker between the inverter and PV modules.

TROUBLE SHOOTING

No response after power on.

Problem LCD/LED/Buzzer Explanation / Possible cause

Unit shuts down automatically during startup process.

LCD/LEDs and buzzer will be active for 3 seconds and then complete off.

The battery voltage is too low (<1.91V/Cell)

No indication.

1. The battery voltage is far too low. (<1.4V/Cell)

2. Battery polarity is connected reversed.

What to do

1. Re-charge battery.

2. Replace battery.

1. Check if batteries and the wiring are

3. Replace battery.

Check if AC breaker is Input voltage is displayed as 0 on the LCD and green LED is flashing.

Input protector is tripped

Mains exist but the unit works in battery mode.

Green LED is flashing.

Green LED is flashing.

Insufficient quality of AC power. (Shore or Generator)

Set “Solar First” as the priority of output source.

1. Check if AC wires are too thin and/or too long.

2. Check if generator (if applied) is working well or if input voltage range setting is correct. (UPS

¹ Appliance)

Change output source priority to Utility first.

When the unit is turned on, internal relay is switched on and off repeatedly.

LCD display and

LEDs are flashing

Fault code 07

Check if battery wires are connected well.

Reduce the connected load by switching off some equipment.

Fault code 05

Output short circuited.

Temperature of internal converter component is over

120°C. (Only available for

1-3KVA models)

Check if wiring is connected well and remove abnormal load.

Check whether the air

Fault code 02 Internal temperature of inverter component is over

100°C.

Battery is over-charged.

Return to repair center.

Fault code 03

The battery voltage is too high.

Check if spec and

Fault code 01 Fan fault Replace the fan.

Fault code 06/58 Output abnormal (Inverter voltage below than 190Vac or is higher than 260Vac)

1. Reduce the connected load.

2. Return to repair center
