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 pos-
sibly lead to water/dampness penetrating the unit.
Like those found in kitchens, areas lled with mineral oil or containing splashed oil or steam. It will deteri-
orate plastic parts of the unit, causing those parts to fail or allow water/damp to penetrate the unit.
Areas that generate substances that adversely aect 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 elec-
tricity reliably.
Areas that can cause combustible gas to leak contain suspended carbon ber or ammable dust or vola-
tile inammable 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 re risk.
Areas where animals may urinate on the uni,t or ammonia, may be generated.
High altitude areas (over 4000 meters above sea level).
Environments where precipitation or humidity are above 95%
Areas where the air circulation is too low.
ALSO CONSIDER:
Installing the indoor unit, outdoor unit, power supply cable, transmission cable, and remote control cable
at least 1 meter 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 ten years old approach the unit, take preventive measures so they cannot reach and
touch the unit.
Install the indoor unit on the wall where the oor height exceeds 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.

LIFELYNK INVERTER | Installer Manual10
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 the recommended spaces (500mm each side / above and
below / front) to guarantee heat dissipation and easy access to the wiring/cabling.
WARNING
Risk of injury (Heavy Object).
Remember that this inverter is heavy, so users must carefully handle the unit during installation,
especially when mounting or removing it from a wall.

LIFELYNK INVERTER | Installer Manual11
4.3. Connecting the Batteries
Before mounting the inverter on the wall, it is better to install the batteries using the xings supplied with the
product, like in the gures 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 reduced accordingly.
No. of Batteries Power Capacity
1 576Wh
2 1152 Wh
3 1728 Wh
4 2304 Wh
5 2880 Wh
WARNING
Setting a power limit higher than maximum will damage the battery fuse.
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.

LIFELYNK INVERTER | Installer Manual12
For safe operation and compliance, an individual DC overcurrent protector or disconnection device is re-
quired to connect the battery and the inverter. Users are recommended to utilize a fuse and DC isolator (see
next page). Some applications may not require switching devices, but overcurrent protectors must be used.
It is also important to set a power limit lower than the inverter’s maximum power. Setting a “Max Sell Power”
grimoire signicant the limit will damage the battery fuse.

LIFELYNK INVERTER | Installer Manual13
4.4. Connecting to the Mains / Grid
1. Connect the Lifelynk 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 central and secondary consumer units are correctly grounded to the Lifelynk Hybrid Inverter.
4.5. Earth Bond (Mandatory)
An earth cable shall be connected to the earth plate on the grid size in order to prevent electric shock if the
original protective conductor fails.
4.6. Neutral Earth Bond
All neutrals can be linked together to maintain the neutral bond. When a Neural Earth bond is required, o-
grids be removed on the grid-tied operation.

LIFELYNK INVERTER | Installer Manual14
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.
4.7. 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 the PV
array.
Do not connect any PV modules with possible current leakage to the inverter to avoid malfunction. For
example, grounded PV modules will cause current leakage to the inverter.
Also, the PV modules’ open-circuit voltage (Voc) does not exceed the maximum input voltage of the in-
verter. Also, the Voc of the PV array should be higher than the minimum starting voltage of the inverter.
Connect the PV panels to the MPPT terminal.
4.8. 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.”

LIFELYNK INVERTER | Installer Manual15
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/o button (lo-
cated on the front of the case) to turn on the system.
When the system is connected without a battery but with either PV or grid and the on/o button is switched
o, the LCD will still light up (display will show o). In this condition, the system can still work when switching
the on/o button and selecting no battery.
