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.

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 100Ah capacity battery for

1-3KVA model and at least 200Ah capacity battery for 4KVA/5KVA model.

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

(-).

6

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.

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.

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)

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)

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’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.

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.

4KVA/5KVA model)

If self-defined is selected in program 5, this program can be set up. Setting range is from 20.0V to 24.0V for 24V model,

40.0V to 48.0V for 48V model. Increment of each click is 0.1V.

Low DC cut-off voltage will be fixed to setting value no matter what percentage of load is connected.

Solar power balance enable (Default):

Solar power balance disable:

If selected, solar input power will be automatically adjusted according to the following formula:

Max. input solar power = Max. battery charging power +

Connected load power.

If selected, the solar input power will be the same to max. battery charging power no matter how much loads are connected. The max. battery charging power will be based on the setting current in program 02.

(Max. solar power = Max. battery charging power)

Problem

Unit shuts down automatically during startup process.

No response after power on.

LCD/LED/Buzzer Explanation / Possible cause

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.

Input voltage is displayed as 0 on the

LCD and green LED is flashing.

Input protector is tripped

1. Check if batteries and the wiring are connected well.

2. Re-charge battery.

3. Replace battery.

Check if AC breaker is tripped and AC wiring is connected well.

What to do

1. Re-charge battery.

2. Replace battery.

Mains exist but the unit works in battery mode. Green LED is flashing.

Insufficient quality of AC power.

(Shore or Generator)

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 Appliance)

Change output source priority to Utility first.

Buzzer beeps continuously and red LED is on.

Green LED is flashing.

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

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

LCD display and LEDs are flashing

Battery is disconnected.

Fault code 07

Fault code 05

Fault code 02

Fault code 03

Fault code 01

Fault code 06/58

Check if battery wires are connected well.

Overload error. The inverter is overload 110% and time is up.

Output short circuited.

Reduce the connected load by switching off some equipment.

Check if wiring is connected well and remove abnormal load.

Temperature of internal converter component is over 120°C. (Only available for 1-3KVA models.)

Internal temperature of inverter component is over 100°C.

Battery is over-charged.

Check whether the air flow of the unit is blocked or whether the ambient temperature is too high.

The battery voltage is too high.

Fan fault

Output abnormal (Inverter voltage below than 190Vac or is higher than 260Vac)

Return to repair center.

Check if spec and quantity of batteries are meet requirements.

Replace the fan.

1. Reduce the connected load.

2. Return to repair center

Fault code

08/09/53/57

Fault code 51

Internal components failed.

Over current or surge.

Return to repair center.

Fault code 52

Fault code 55

Bus voltage is too low.

Output voltage is unbalanced.

Restart the unit, if the error happens again, please return to repair center.
