1. SAFETY
This device should only be used in accordance with the instructions within this manual and in
compliance with local, regional, and national laws and regulations. Only allow this device to be installed,
operated, maintained, and repaired by other person(s) who have read and understood this manual.
Ensure the manual is included with this device should it be passed to a third party.
DO NOT allow minors, untrained personnel, or person(s) suering from a physical or mental impairment
that would aect their ability to follow this manual, install, maintain or repair this device.
Any untrained personnel who might get near this device while it is in operation MUST be informed that it
is dangerous and instructed carefully on how to avoid injury.
1.1. General Safety
1.2. Symbols
WARNING This symbol indicates information that if ignored, could result in personal
injury or even death due to incorrect handling.
CAUTION This symbol indicates information that if ignored, could result in personal
injury or physical damage due to incorrect handling.
PLEASE NOTE Indicates information that is considered important, but not hazard-related.

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 qualied 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 cen-
tre.
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/cables before performing any maintenance or cleaning to reduce the risk of electri-
cal 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 o since the
system can still have residual energy, so an electric shock may occur. Therefore, after turning o 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 elec-
tronic-waste disposal. In case of further questions, please consult your supplier. In some cases, the supplier
can take care of proper disposal.
WARNING
HIGH LIFE RISK DUE TO FIRE OR ELECTROCUTION.
Sunsynk Single-Phase Hybrid Inverter can only be installed by a qualied licensed electrical contrac-
tor. This is not a DIY product.

2. PRODUCT INTRODUCTION
The Sunsynk Single-Phase Hybrid Inverter is a highly ecient power management tool that allows the user
to hit those ‘parity’ targets by managing power-ow from multiple sources such as solar, mains power (grid),
and generators, and then eectively storing and releasing power as and when utilities require.
INTERACTIVE
Easy and simple to understand display
Supporting Wi-Fi or GSM monitoring
Visual power ow screen
Smart settable 3-stage MPPT charging for optimized battery performance
Auxiliary load function
Parallel / multi invert function grid-tied and o-grid
COMPATIBLE
Compatible with main electrical grid voltages or power generators
Compatible with wind turbines
220V single phase, pure sinewave inverter
Self-consumption and feed-in to the grid
Auto restart while AC is recovering
Auto earth bond feature (Via a relay)
CONFIGURABLE
Fully programmable controller
Programmable supply priority for battery or grid
Programmable multiple operation modes: on-grid/o-grid & UPS
Congurable battery charging - current/voltage based on applications by LCD setting
Congurable AC / solar / generator charger priority by LCD setting
SECURE
Overload/over-temperature/short-circuit protection
Smart battery charger design for optimized battery protection
Limiting function installed to prevent excess power overow to grid
APPLICATIONS
Marine (vessel power management)
Power shedding (home/oce/factory)
UPS (fuel-saving systems)
Remote locations with solar and wind generators
Building sites

2.2. Basic System Architecture
The following illustration shows the basic application of this inverter.
It also includes the following devices to have a Complete running system.
Generator or Utility
PV modules
Consult with your system integrator for other possible system architectures depending on your require-
ments
This inverter can power all kinds of appliances in a home or one environment, including motor-type
appliances such as refrigerators and air conditioners
When no PV is connected, the inverter can be used for just UPS functionality.
