Before using the inverter, please read all instructions and cautionary markings on the unit and manual.
Put the instructions where you can take them easily.
The three phase hybrid inverter of ours strictly conforms to related safety rules in design and test. Local
safety regulations shall be followed during installation, operation and maintenance. Incorrect operation
work may cause injury or death to the operator or a third party and damage to the inverter and other
properties belonging to the operator or a third party.
1.1 Symbols Used
1.2 Safety Precaution
Installation,maintenance and connection of inverters must be performed by qualified personnel, in
compliance with local electrical standards, wiring rules and requirements of local power authorities
and/or companies(for example: AS 4777 and AS/NZS 3000 IN Australia).
To avoid electric shock, DC input and AC output of the inverter must be terminated at least 5 minutes
before performing any installation or maintenance.
The temperature of some parts of the inverter may exceed 60℃ during operation. Do not touch the
inverter during operation to avoid being burnt and let it cool before touching it.
Ensure children are kept away from inverters.
Don’t open the front cover of the inverter. A part from performing work at the wiring terminal (as
instructed in this manual), touching or changing components without authorization may cause injury
to people, damage to inverters and annulment of the warranty.
Static electricity may damage electronic components. Appropriate method must be adopted to prevent
such damage to the inverter; otherwise the inverter may be damaged and the warranty annulled.
Ensure the output voltage of the proposed PV array is lower than the maximum rated input voltage of
the inverter; otherwise the inverter may be damaged and the warranty annulled.
When exposed to sunlight, the PV array generates dangerous high DC voltage. Please operate according
to our instructions, or it will result in danger to life.
PV modules should have an IEC61730 class A rating.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
Completely isolate the inverter before maintaining. Completely isolate the inverter should: Switch off
the PV switch, disconnect the PV terminal, disconnect the battery terminal, and disconnect the AC
terminal.
Prohibit to insert or pull the AC and DC terminals when the inverter is running.
In Australia, the inverter internal switching does not maintain the neutral integrity, neutral integrity must
be addressed by external connection arrangements.
In Australia, the output of backup side in switchbox should be labeled main switch UPS supply, the
output of normal load side in switchbox should be labeled mains switch inverter supply.
Don’t connect Three phase hybrid inverter in the following ways:
BACKUP Port should not be connected to grid;
The single PV panel string should not be connected to two or more inverters.

2.1 Overview
Hybrid Inverter
The hybrid inverters are high-quality inverter which can convert solar energy to AC energy and store
energy into battery.
The inverter can be used to optimize self consumption, store in the battery for future use or feed into
public grid. Work mode depends on PV energy and user’s preference. It can provide power for emergency
use during the grid lost by using the energy from battery and inverter (generated from PV).

4.1 Grounding
A protective earth (PE) terminal is equipped at the side of the inverter. Please be sure to connect this
PE terminal to the PE bar for reliable grounding. AWG 10 yellow green lines are recommended.
4.2 GRID/BACKUP Connection
Before connecting the GRID/BACKUP terminal, ensure that both the AC terminal and the DC terminal are
powered OFF and the PV switch is OFF. Otherwise there is a risk of high voltage shock.
GRID/BACKUP connection please refer to below.
Step 1: Assemble the AC connector.
If the positive pole or negative pole of the PV array is required to
be grounded, then the inverter output (to AC grid) must be isolated
by transformer in accordance with IEC62109-1, -2 standards.
CAUTION
Ensure that inverter and all cables to be installed are completely powered
off during whole installation and connection. Otherwise, fatal injury can
occur due to the high voltage.

4.3 Battery Connection
Three phase hybrid inverter now only supports the lithium / lead-acid battery.
This part in this manual only describe the battery connection on inverter side. If you need more detailed
connection information about the battery side, please refer to the manual of the battery you using.
Before connecting to battery, please install a separate DC breaker between inverter and battery.
This ensure the inverter can be security disconnected during maintenance.
Step 2: Connect the AC connector.
An AC breaker should be installed between inverter and the GRID/BACKUP.
a. Before connecting the AC cable from inverter to AC breaker, you should confirm the AC
breaker is working normally. Turn off the AC breaker and keep it open.
b. Connect the PE conductor to grounding electrode, and connect the N and L conductors to
AC breaker.
c. Connect the AC breakers to the GRID/BACKUP grid.
To ensure that the inverter can be safely and reliably disconnected from the grid, a AC breaker（≥50A）
should be installed only for inverter GRID/BACKUP port..
Battery Communication Connection
If the battery type is lithium battery which need communication between the inverter and
battery management system (BMS), the connection must be installed.
Please refer to section 4.6.1 for details.

5.1 Inverter Working Mode
The inverter supports several different working modes.
5.1.1 Self Used Mode
Go to the "Hybrid work mode" menu, and select the "Self used mode" working mode.
Under Self Used mode, the priority of PV energy will be Load > Battery > Grid, that means the energy
produced by PV gives priority to local loads, excess energy is used for charging the battery, and the
remaining energy is fed into the grid.
This is the default mode to increase self-consumption rate. There are several situations of Self
used working mode based on PV energy.
a) Wealthy PV Energy
When PV energy is wealthy, the PV energy will first consumed by loads, the excess energy
will be used to charge the battery. then the remaining energy will be fed into the grid.
b) Limited PV power
When the PV energy is not enough to cover all the loads, all the PV energy will be used for load, and
the insufficient part will be supported by battery. Then still insufficient parts will be supported by grid.

a) Wealthy PV Energy
When PV energy is wealthy, the PV energy will be first consumed by loads, if there is
excess PV power, then the excessive power will be fed into grid. If there is still PV energy
rested after load consuming and grid feeding, then the rested PV power will be used to charge
the battery.
c) No PV Input
The inverter will first discharge the battery energy for home load consuming when no PV
input( such as in the evening or some cloudy or rainy days). If the demand is not met then will
consume the grid energy.
b) Limited PV Energy
When PV energy is limited and can not meet the feed-in grid power, the battery will discharge
to meet it.
5.1.2 Feed-in Priority Mode
Go to the "Hybrid work mode" menu, and select the "Feed-in priority mode" working mode.
Under this mode, the priority of PV energy will be Load > Grid > Battery, that means the
energy produced by PV gives priority to local loads, excess energy is fed into the grid, and the
remaining energy is used for charging the battery.
