Australian Manual
For Australian market, a grid code must be selected before the inverter can operate. For compli-
ance with AS/NZS 4777.2:2020 please select from Australia A, Australia B, Australia C or New
Zealand. Please contact your local grid operator for which region to select.
This inverter complies with IEC 62109-2 clause 13.9 for earth fault alarm monitoring. If an Earth
Fault Alarm occurs, the fault code F24 will be displayed on the inverter screen /the LED indica-
tor fault will light up.

1. SAFETY
This device should only be used in accordance o instructions within this manual and in
compliance with local, regional and national laws and regulations. Only allow this device
to be installed, operated, maintained, repaired by other persons who have also read and
understood this manual. Ensure the manual is included with this device should it be passed
to a third party.
DO NOT allow minors, untrained personnel, or person(s) suffering from a physical or mental
impairment that would affect their ability to follow this manual, install, maintain or repair this
device.
Any untrained personnel who might get near this device while it is in operation MUST be
informed that it is dangerous and instructed carefully on how to avoid injury.

1.1. General Safety
This symbol indicates information that if ignored, could result in per-
sonal injury or even death due to incorrect handling.
This symbol indicates information that if ignored, could result in per-
sonal injury or physical damage due to incorrect handling.
Indicates information that is considered important, but not haz-
ard-related.
1.2. Symbols

1.3. Safety Instructions
Be sure to read this manual thoroughly before installation.
Do not attempt to install the inverter by yourself. Installation work must be carried out in
compliance with national wiring standards and by suitably qualified personnel only. Do not
turn on the power until all installation work is complete.
Do not disassemble the inverter. If you need repair or maintenance, contact a professional
service centre.
Always use an individual power supply line protected by a circuit breaker and operating on
all wires with a distance between contacts of at least 3mm for this unit.
The unit must be correctly grounded and the supply line must be equipped with a suitable
breaker and RCD to protect people.
Disconnect all wires/cables before performing any maintenance or cleaning to reduce the
risk of electrical shock.
The unit is not explosion-proof, so it should not be installed in an explosive atmosphere.¬
Never touch electrical components immediately after the power supply has been turned off
since the system can still have residual energy, so electric shock may occur. Therefore, after
turning off the power, always wait 5 minutes before touching electrical components.
This unit contains no user-serviceable parts. Always consult an authorised contractor for
repairs.
HIGH LIFE RISK DUE TO FIRE OR ELECTROCUTION.
The Sunsynk Single-Phase Hybrid Inverter can only be installed by a qualified li-
censed electrical contractor. This is not a DIY product.
1.4. Disposal Remarks
DO NOT dispose this product with domestic waste!
Electrical devices should be disposed of in accordance with regional directives on electronic
and/ or electronic-waste disposal. In case of further questions, please consult your supplier. In
some cases, the supplier can take care of proper disposal.

4. INSTALLATION
4.1. Parts List
Check if you received all the items listed below. Ensure that nothing is damaged in the package.
Page | 15Hybrid Inverter | Installer Manual

4.2. Selecting the Mounting Area
Page | 16 Hybrid Inverter | Installer Manual
For proper heat dissipation, allow a clearance of approximately 500mm to the side, 500mm
above and below the unit, and 1000mm to the front of the unit.
DO NOT install the inverter in the following areas:
Areas with high salt content, such as the marine environment. It will deteriorate the metal
parts and possibly lead to water/dampness penetrating the unit.
Areas filled with mineral oil or containing splashed oil or steam such as found in kitchens. It
will deteriorate plastic parts of the unit, causing those parts to fail or allow water/damp to
penetrate the unit.
Areas that generate substances that adversely affect the equipment, such as sulphuric gas,
chlorine gas, acid, or alkali. These can cause the copper pipes and brazed joints to corrode
and fail to conduct electricity reliably.
Areas that can cause combustible gas to leak, which contains suspended carbon-fibre or
flammable dust, or volatile inflammable such as paint thinner or gasoline.
Areas where there may be gas leaks and where gas may settle around the unit as this is a
fire risk.
Areas where animals may urinate on the unit or ammonia may be generated.
High altitude areas (over 4000 metres above sea level).
Environments where precipitation or humidity are above 95%
Areas where the air circulation is too low.

4.3. Mounting the Inverter
ALSO CONSIDER:
Installing the indoor unit, outdoor unit, power supply cable, transmission cable, and remote
control cable at least 1 metre away from any television or radio receiver. This will prevent TV
reception interference or radio noise. This will prevent radio signal interference from external
units that might interfere with the Wi-Fi or GSM monitoring.
If children under 10 years old may approach the unit, take preventive measures so that they
cannot reach and touch the unit.
Install the indoor unit on the wall where the height from the floors is higher than 1600mm.
Before connecting all wires, please take the metal cover off removing the screws as shown
below:
Select installation locations that adequate to support the weight of the converter.
Install this inverter at eye-level to allow the LCD to be read anytime.
An appropriate ambient temperature is between -25 ~ 60°C to ensure optimal operation.
Be sure to keep other objects and surfaces as shown in the figure to guarantee sufficient
heat dissipation and have enough space to remove wires.
For proper air circulation to dissipate heat, allow a clearance of approximately 50cm to the
side.
Page | 17Hybrid Inverter | Installer Manual
Risk of injury (Heavy Object)
Remember that this inverter is heavy (45kg) so users must be careful in handling
the unit during installation especially when mounting or removing from a wall.

Choose the recommend drill head (as shown in below pic) to drill 4 holes on the wall, 52-60mm
deep.
1. Use a proper hammer to fit the expansion bolt into the holes.
2. Carry the inverter and holding it, make sure the hanger aim at the expansion bolt,fix the
inverter on the wall.
3. Fasten the screw head of the expansion bolt to finish the mounting.

Page | 19Hybrid Inverter | Installer Manual
4.4. Battery Connection
For safe operation and compliance, an individual DC overcurrent protector or disconnection
device is required for the connection of the battery and the inverter. Users are recommended to
utilise a suitable fuse and DC isolator (see next page). In some applications, switching devices
may not be required, but overcurrent protectors must be used. Please refer to the typical am-
perage in the table below for the required fuse or circuit breaker size.
Model Wire Size Cable (mm2) Torque value (max.)
8kW 1AWG 40 24.5N.m
10kW 1/0 AWG 60 24.5N.m
12kW 1/0 AWG 60 24.5N.m
Please follow below steps to implement battery connection:
1. Please choose a suitable battery cable (appropriate rating) with the correct connector to
attach to the battery terminals.
2. Use a suitable screwdriver that matches the bolt size to unscrew the bolts to fit the battery
connectors. Then tighten the bolts with the connectors in place with a torque of 24.5N.m
in a clockwise direction.
3. Make sure polarity is correct at both the battery and inverter terminals
Battery connector screw size: M10.
Reverse Polarity
All wiring/connecting must be performed by qualified personnel. Before making
the final DC connection or closing the DC Breaker/disconnection device, ensure
the inverter unit is wired correctly. A reverse-polarity connection on the battery will
damage the inverter.
