Selecting the Mounting Area
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 lled with mineral oil or containing splashed oil or steam, such as those found in kitchens. It will
deteriorate plastic parts of the unit, causing those parts to fail or allowing 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 is 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 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.

THREE PHASE HI 29.9/50kW | Installer Manual15
Mounting the Inverter
Select installation locations that are adequate to support the weight of the converter.
Install this inverter at eye level to allow the LCD to be read anytime.
To ensure optimal operation, an appropriate ambient temperature is between -40 and 60°C.
Be sure to keep other objects and surfaces, as shown in the gure to guarantee sucient heat dissipa-
tion and have enough space to remove wires.
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.
Choose the recommended drill head (as shown below) to drill 4 holes on the wall, 62-70mm deep.
1. Use a proper hammer to t the expansion bolt into the holes.
2. Carry the inverter and hold it, 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.
If children under 10 years old may 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 is higher than 1600mm.
Before connecting all wires, please take the metal cover o, removing the screws as shown below:

Inverter Hanging Plate Installation
Battery Connection
For safe operation and compliance, an individual DC overcurrent protector or disconnection device is
required to connect the battery and the inverter. Users are recommended to utilise a suitable fuse and DC
isolator (see next page). Switching devices may not be required in some applications, but overcurrent pro-
tectors must be used. Please refer to the typical amperage in the table below for the required fuse or circuit
breaker size.

WARNING
Reverse Polarity.
Before making the nal DC connection or closing DC breaker/disconnect, be sure positive (+) must be
connected to the positive (+) and negative (-) must be connected to the negative (-). A reverse polarity
connection on the battery will damage the inverter.
All wiring/connecting must be performed by qualied personnel. In addition, connecting the battery
with a suitable cable is essential for safe and ecient operation of the system

THREE PHASE HI 29.9/50kW | Installer Manual19
Grid and Backup Load Connection
Before connecting to the grid, please install a separate AC breaker between the inverter and the grid.
Also, it is recommended that installs an AC breaker between the backup load and inverter. This will ensure
that the inverter can be securely disconnected during maintenance and fully protected from overcurrent.
For the 29.9/30/35/40/50KW model, the recommended AC breaker for the backup load is 240A. For the
29.9/30/35/40/50KW model, the recommended AC breaker for grid is 240A.
There are three terminal blocks marked as GRID, LOAD, and GEN. Please do not confuse input and output
connections. External AC SPD is compulsory on all Sunsynk inverters.
WARNING
All wiring must be performed by qualied personnel. System safety and ecient operation need to
use appropriate cable for AC input connection. To reduce the risk of injury, please use the proper
recommended cables as below.

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
disconnector rst.
2. Remove a 10mm sleeve from each wire, unscrew the bolts, insert the cables according to the polarities
indicated on the terminal block and tighten the terminal screws. Ensure the connection is complete.
WARNING
Ensure the AC power source is disconnected before attempting to wire it to the unit.

THREE PHASE HI 29.9/50kW | Installer Manual20
PV Connection
Before connecting to PV modules, please install a separate DC circuit breaker between the inverter and PV
modules. It is very important for system safety and ecient operation to use appropriate cable for PV mod-
ule connection. To reduce the risk of injury, please use the proper recommended cable size as below.
WARNING
To avoid malfunction, do not connect any PV modules with possible leakage current to the inverter.
For example, grounded PV modules will cause leakage current to the inverter. When using PV mod-
ules, please ensure the PV+ & PV- of the solar panel are not connected to the system ground bar.
It is requested to use a PV junction box with surge protection. Otherwise, it will cause damage to the
inverter when lightning occurs on PV modules.
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. Appliances such as air conditioners require at least 2-3 minutes to restart because it requires enough
time to balance refrigerant gas inside the circuit. If a power shortage occurs and recovers in a short time,
it will cause damage to your connected appliances. To prevent this kind of damage, please check with the
air conditioner manufacturer if it is equipped with a time-delay function before installation. Otherwise,
this inverter will trigger an overload fault and cut o output to protect your appliance, but sometimes it
still causes internal damage to the air conditioner
PV Module Selection
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit voltage (Voc) of PV modules can not exceed the max. PV array open circuit voltage of the
inverter.
2. Open circuit voltage (Voc) should be higher than min. start voltage.
3. The PV modules connected to this inverter shall be Class A rating certied according to lEC 61730.
