1 Safety
WARNING !! HIGH RISK OF FIRE OR ELECTROCUTION.
The Sunsynk Parity Hybrid inverter can only be installed by a qualied
licensed electrical contractor this is NOT a DIY product.
• Be sure to read this manual thoroughly before installation.
Do not attempt to install the inverter by yourself. Installation work must be performed in accordance with
national wiring standards by authorised personnel only. Do not turn on the power until all installation work
is complete.
• Always use a separate power supply line protected by a circuit breaker operating on all wires with a
distance between contact of 3mm for this unit.
• The unit must be correctly grounded and the supply line must be equipped with a suitable breaker and
RCD in order to protect the persons.
• The units are not explosion proof and therefore should not be installed in explosive atmosphere.
• Never touch electrical components immediately after the power supply has been turned off. Electric shock
may occur. After turning off the power, always wait 5 minutes before touching electrical components.
• This unit contains no user-serviceable parts. Always consult authorised service person for repairs.

3.00 Installing the Inverter
3.01 Installing the Inverter
Do not install the unit in the following areas:
• Area with high salt content, such as marine environment. It will deteriorate metal parts, causing the parts
to fail or the unit to leak water.
• Area lled with mineral oil or containing a large amount of splashed oil or steam, such as a kitchen. It will
deteriorate plastic parts, causing the parts to fail or the unit to leak water.
• Area that generates substances that adversely affect the equipment, such as sulphuric gas, chlorine gas,
acid, or alkali. It will cause the copper pipes and brazed joints to corrode, which can cause refrigerant
leakage.
• Area that can cause combustible gas to leak, contains suspended carbon-bre or ammable dust, or vola
tile inammables such as paint thinner or gasoline.
• If gas leaks and settles around the unit, it can cause a re.
• Any area where animals may urinate on the unit or ammonia may be generated.
• Do not install at an altitude above 2000 meters above sea level.
• Do not install in an environment of precipitation or humidity above 95%
• Do not Install the unit where drainage is problematic. ALSO CONSIDER :-
• Install the indoor unit, outdoor unit, power supply cable, transmission cable, and remote control cable at
least 1 m away from a television or radio receivers. The purpose of this is to prevent TV reception
interference or radio noise.
• (Even if they are installed more than 1 m apart, you could still receive noise under some signal conditions.)
• If children under 10 years old may approach the unit, take preventive measures so that they cannot reach
the unit.
• Install the indoor unit on the wall where the height from the oors more than 1800 mm.

3.02 Mounting the Inverter
Fixing the inverter to a wall
Select installation locations that can properly support the weight of the unit.
Install this inverter at eye-level in order to allow the LCD display to be read at all times.
The ambient temperature should be between -25~60°C to ensure optimal operation.
Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and have enough
space for removing wires.
For proper air circulation to dissipate heat, allow a clearance of approx. 50cm to the side.
Remember that this inverter is heavy! Please be careful when
lifting out from the package.
removing the inverter from the packaging and mounting onto
the wall

3.03 Battery Connection
For safe operation and compliance, a separate DC over-current protector or disconnect device (see next page) is
required between the battery and the inverter. In some applications, switching devices may not be required but
over-current protectors are still required.
Recommend minimum battery cable size of 5.5kW 35mm diameter and 8.8kW 50mm diameter.
Before making the nal DC connection or closing DC breaker / disconnection; ensure the inverter is wired to the
correct. Reverse polarity connection on battery will damage the inverter.

Ensure suitable disconnection
devices and RCDs are tted.
Cable sizing should be used
as per the countries code of
practice.
All wiring must be in accordance with the country wiring regulations and
code of practices
Gen:- This is for connection of a generator controlling a micro-inverter or smart-load.
Load:- This is the off-grid inverter and can be used as a UPS.
Grid:- This is the on-grid (parity) export limiting the grid tie inverter.

3.05 Installing the Coil
The CT coil is one of the most important parts of the Sunsynk parity inverter, this is the device that senses
any export power and reduces the power of the inverter to obtain zero export.
Fit the coil (sensor) around the live cable on the main fuse feeding the building (see below) and run the
cable back to the inverter, this cable can be extended up to an extra 10 metres using similar cable.
Connect the other end of the CT coil into the inverter terminals marked CT coil (see the pic below to the
right).
IMPORTANT Check the coil is tted correctly less the battery icon to see the screen below.
If the CT coil is tted backwards it will show on the HM power a negative value will be shown on the screen
below, if this is the case turn the CT coil by 180’ (re - check).

The inverter has two built-in MPPT controllers; MPPT 1 and MPPT 2, which can connect two sets of panels in
parallel with a maximum current of 18 Amp (as above). Before connecting to PV modules, install a separate
DC circuit breaker between the inverter and PV modules. 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. Open circuit voltage (Voc) of PV modules not exceeds max. PV array open circuit
voltage open circuit voltage (Voc) of PV modules should be higher than min. start voltage.
