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 before performing any maintenace or clearning to reduce the
risk of electric 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.
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. Selecting the Mounting Area
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.
INSTALLATION

10
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.
 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.
4.2. Mounting the Inverter
 Select a location that provides adequate to support the weight of the inverter.
 Install this inverter so that the LCD screen is eye-level for easy operation.
 An appropriate ambient temperature lies between -25 ~ 60°C for optimal operation.
 Ensure other objects and surfaces are outside of the recommended spaces (500mm
each side / above and below / front) to guarantee heat dissipation and easy access
to the wiring/cabling.
Risk of injury (Heavy Object)
Remember that this inverter is heavy so users must be careful in handling
the unit during installation especially when mounting or removing from a
wall
.
CAUTION

11
4.3. Connecting the Batteries
Before mounting the inverter on the wall, it is better to install the batteries using the
fixings supplied with the product like in the figures below.
A minimum battery cable size of 35mm diameter is recommended.
The Lifelynk uses a set of batteries that provide 2880Wh of energy. Therefore, if fewer
batteries are installed, the power capacity will be reduce accordingly.
No. of Batteries Power Capacity
1 576 Wh
2 1152 Wh
3 1728 Wh
4 2304 Wh
5 2880 Wh
If using an external battery, connect it to the +V and V- bus bar, but please be sure to
select a suitable fuse and battery isolator.
Setting a power limit higher than maximum will damage the battery fuse.
CAUTION

12
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.
It is also important to set a power limit lower than the maximum power of the inverter.
If you set a “Max Sell Power” greater than the limit, it will damage the battery fuse.

4.4. Connecting to the Mains / Grid
1. Connect the Lyfelynk Hybrid Inverter to the electrical grid via the "Grid" ports, using
a suitable RCD and a 20 A fuse on the consumer board.
2. Now, using a 4 mm cable, connect only the essential loads to the "Load" ports
(Output) to a secondary consumer board, considering the maximum limit of 3.6 kW.
3. Ensure the main consumer unit and the secondary consumer unit are correctly
grounded to the Lifelynk Hybrid Inverter.
4.5. Earth Bond (Mandatory)
An earth cable shall be connected to earth plate on the grid size in order to prevent
electric shock if the original protective conductor fails.
4.5.1 Neutral Earth Bond
All neutrals can be linked together to maintain the neutral bond. When Neural Earth
bond is required for off-grid, then it has to be removed on grid-tied operation.

15
If an earth bond is required between neutral and earth and your system is a hybrid system then
you can have a permanent earth wire since this can cause faults with an RCD before the
inverter.
4.6. Wiring the PV Panels
 The Lifelynk Hybrid Inverter has an MPPT controller with a maximum input current
of 9 A.
 Before connecting to PV modules, install a separate DC circuit breaker between the
inverter and PV array.
 To avoid any malfunction, do not connect any PV modules with possible current
leakage to the inverter. For example, grounded PV modules will cause current
leakage to the inverter.
 Also, the open-circuit voltage (Voc) of the PV modules does not exceed the
maximum input voltage of the inverter. Also, the Voc of the PV array should be
higher than the minimum starting voltage of the inverter.
 Connect the PV panels into the MPPT terminal.
4.7. CT Coil and Load Power Settings
The CT coil is one of the most important parts of the Sunsynk Parity inverter. This
device reduces the power of the inverter to prevent feeding power to the grid. This is
also known as "Zero Export".
 Fit the coil (sensor) around the live cable on the main fuse feeding the building and
run the cable back to the inverter. This cable can be extended up to an extra 10m
using a similar cable.
 Connect the other end of the CT coil into the inverter terminals marked as “CT Coil”.

16
You can access the CT Coil Screen directly from the Home Screen.

5.2. Switching ON/OFF
Once the inverter has been correctly installed and the batteries are connected, press
the on/off button (located on the front of the case) to turn on the system.
When the system is connected without a battery but connected with either PV or grid
and the on/off button is switched off, the LCD will still light up (display will show off). In
this condition, when switching on the on/off button and selecting no battery, the system
can still work.
