The inverter x1

User manual x 1

Communication cable x 1

4.2 Preparation

Please remove the two screws on the bottom cover of the inverter as shown below before connecting

all wirings.

4.3 Mounting The Unit

Consider the below points before selecting where to install:

1. Do not mount the inverter on the surface of flammable construction materials. 2. Mount on the surface of a solid material.

3. Install the inverter at a visible place in order to the LCD display can be read easily.

4. For proper air circulation and dissipate heat ,make sure there is 20 cm distance from the two side,

50 cm distance from bottom of the unit.

5.The ambient temperature should be between -10°C and 50°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 collecting 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 adopt a separate DC

over-current protector or disconnect device between battery and inverter. It may not be necessary to

have a disconnect device in some applications, however, it’s still need to adopt over-current

protection device. 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 cable as below.

CAUTION! Before connection the DC breaker, 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 and lightning arrester 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 3.5KVA and 50A for 5.5KVA. There are two terminal blocks with “IN” and “OUT” markings. Please do NOT connect input and output connectors wrong. 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 AC input connection. To reduce risk of injury, please use the proper recommended cable size as below.

6.TROUBLE SHOOTING

Problem

LCD/LED/Buzzer Explanation / Possible cause

What to do

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)

1. Re-charge battery. 2. Replace battery.

No response after power on.

No indication.

Input voltage is displayed as 0 on the LCD and green LED is flashing.

1. The battery voltage is far too low. (<1.4V/Cell) 2. Internal fuse tripped.

1. Contact repair center for replacing the fuse. 2. Re-charge battery. 3. Replace battery.

Input protector is tripped

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

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

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.

Green LED is flashing.

Set “SUB” (solar first) as the priority of output source.

Change output source priority to “USB” (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
Buzzer beeps continuously and red LED is on.
Fault code 05
Fault code 02

Battery is disconnected.

Check if battery wires are connected well.

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

Reduce the connected load by switching off some equipment.

If PV input voltage is higher than specification, the output power will be derated. At this time, if connected loads is higher than derated output power, it will cause overload.

Reduce the number of PV modules in series or the connected load.

Output short circuited.
Temperature of internal converter component is over 120°C.
Internal temperature of inverter component is over 100°C.

Check if wiring is connected well and remove abnormal load.
Check whether the air flow of the unit is blocked or whether the ambient temperature is too high.

Check if spec and quantity of batteries are meet requirements.

Fan fault Output abnormal (Inverter voltage below than 190Vac or is higher than 260Vac)
Internal components failed.

Replace the fan. 1. Reduce the connected load. 2. Return to repair center
Return to repair center.

Over current or surge.
Bus voltage is too low.
Output voltage is unbalanced. PV input voltage is beyond the specification.

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