Selecting the Mounting Area
This Sunsynk MAX is designed for outdoor use (IP65).
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.
Areas lled with mineral oil or containing splashed oil or steam such as found in kitchens. It will deterio-
rate 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, which contains suspended carbon-bre or ammable
dust, or volatile 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 unit or ammonia may be generated.
High altitude areas (over 2000 metres above sea level).
Environments where precipitation or humidity are above 95%.
Areas where the air circulation is too low.
Please AVOID direct sunlight, rain exposure, snow laying up during installation and operation. Before con-
necting all wires, please take o the metal cover by removing screws as shown below:
Considering the following points before selecting where to install:
Please select a vertical wall with load-bearing capacity for installation, suitable for installation on concrete
or other non-ammable surfaces, installation is shown below.
Install this inverter at eye level in order to allow the LCD display to be read at all times.
The ambient temperature is recommended to be between -40~60ºC to ensure optimal operation.
Be sure to keep other objects and surfaces as shown in the diagram to guarantee sucient heat dissipa-
tion and enough space to remove wires.
Install the indoor unit on the wall where the oor height 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.

SUNSYNK MAX | Installer Manual14
≥500mm
≥500mm
Mounting the Inverter
Choose the recommended drill head (as shown below pic) to drill 4 holes in the wall, 82-90mm deep.
1. Use a proper hammer to t the expansion bolt into the holes.
2. Carry and hold the inverter, ensure the hanger aims at the expansion bolt, and x the inverter on the
wall.
3. Fasten the screw head of the expansion bolt to nish the mounting.
WARNING
For proper air circulation to dissipate heat, allow a clearance of approx. 50cm to the side and approx.
50cm above and below the unit. And 100cm to the front.
WARNING
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 it from a wall.

SUNSYNK MAX | Installer Manual15
Battery Connection
For safe operation and compliance, a separate DC over-current protector or disconnect device is required
between the battery and the inverter. In some applications, switching devices may not be required but
over-current protectors are still required. Refer to the typical amperage in the table below for the required
fuse or circuit breaker size.

WARNING
All wiring/connecting must be performed by qualied personnel. Before making the nal DC con-
nection 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.

SUNSYNK MAX | Installer Manual16
Please follow below steps to implement battery connection:
1. Please choose a suitable battery cable with correct connector which can well t into the battery termi-
nals.
2. Use a suitable screwdriver to unscrew the bolts and t the battery connectors in, then fasten the bolt by
the screwdriver, make sure the bolts are lightened with torque of 12.5 N.M in clockwise direction.
3. Make sure polarity at both the battery and inverter is correctly connected.
4. In case of children touch or insects go into the inverter, please make sure the inverter connector is fas-
ten to waterproof position by twist it clockwise.

DC Battery Input
Pass the battery power cable
through the magnetic ring and
wrap it around the magnetic
ring two times.
Pass the BMS communication cable
through the magnetic ring and wrap
it around the magnetic ring four times.
WARNING
Reverse Polarity.
Before making the nal DC connection or closing DC breaker/disconnect, be sure positive(+) must be
connect to positive(+) and negative(-) must be connected to negative(-). Reverse polarity connection
on battery will damage the inverter.

Connecting the AC
GEN/AUX Generator connection.
GRID This works like a conventional grid-tied inverter. It is both an input and output connection
for non-essential load and supply.
LOAD Connection of essential loads such as lighting, security systems, and Internet
Please follow the steps below to implement GRID, LOAD, and GEN port connections:
1. Before making GRID, LOAD, and GEN port connections, make sure to turn o the AC breaker or discon-
nector rst.
2. Remove a 10mm sleeve from each wire, unscrew the bolts, insert the wires according to the polarities
indicated on the terminal block and tighten the terminal screws. Ensure the connection is complete.
3. Then, insert AC output wires according to the polarities indicated on the terminal block and tighten the
terminal. Make sure to connect corresponding N wires and PE wires to related terminals as well.
4. Ensure the wires are securely connected.
5. Check that the AC power source is isolated before attempting to connect it to the inverter. Insert AC out-
put wires according to the polarities indicated on the terminal block and tighten the terminal screws. Be
sure to connect the corresponding N wires and PE wires to the correct terminals and ensure the wires
are securely connected.
Before connecting to grid, please install a separate AC breaker between inverter and grid. Also, it is recom-
mended that installs an AC breaker between backup load and inverter. This will ensure the inverter can be
securely disconnected during maintenance and fully protected from over current.
There are three terminal blocks with “Grid” “Load”and “GEN” markings. Please do not misconnect input and
output connectors.
