ESS Inverter User Manual 5
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 ESS 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.
Danger of high voltage and electric shock!
Only qualified personnel may perform work on the inverter.

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.
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.
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 inserting or pulling 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.

ESS Inverter User Manual 7
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).
