USER MANUAL
1、introduction：
The GS Energy storage inverter (hybrid) are bidirectional which apply to PV system with battery to storage energy.
Energy produced by the PV system is used to optimize self-consumption; excess energy is used to charge the
batteries, and then feed into the public grid when the PV energy is adequate.
When PV energy output is insufficient to support connected loads, the system automatically discharge energy from
the batteries if battery capacity is abundant. If the battery energy is insufficient to meet own consumption
requirements, electricity will be drawn from the public grid.
The GS Energy storage inverter is designed for both indoor and outdoor use.
2、Important Safety Warning
Before using the inverter, please read all instructions and cautionary markings on the unit and this manual. Store
the manual where it can be accessed easily.
The GS Energy storage inverter of Gsmart(Ningbo) Energy Storage Technology Co.,Ltd (hereinafter referred to as
Gsmart) strictly conforms to related safety rules in design and test.
Safety regulations relevant to the location shall be followed during installation, operation and maintenance.
Improper operation may have a risk of electric shock or damage to equipment and property.

2.2 Safety
Installation, maintenance and connection of inverters must be performed by qualified personnel, in
compliance with local electrical standards, wiring rules and the requirements of local power authorities
and/or companies.
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. To avoid being burnt,
do not touch the inverter during operation. Let it cool before touching it.
Ensure children are kept away from inverters.

08
Do not open the front cover of the inverter. Apart 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 is result in danger to life.
PV modules should have an IEC61730 class A rating.
If the equipment is used in manner not specified by the manufacturer, the protection provided by the may
be impaired.
Completely isolate the inverter before maintaining. Completely isolate the inverter should: Switch off the
DC switch, disconnect the terminal, disconnect the battery terminal, and disconnect the AC terminal.
Prohibit to insert or pull the AC and DC terminal, and 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 like the example proposed in the diagram 4.10.
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 ’main switch inverter supply’.
Don’t connect GS Energy storage inverter in the following ways:
1) UPS port should not be connected to grid;
2) UPS port should not be connected in parallel;
3) The single PV panel string should not be connected to two or more inverters;
4) On grid or UPS port should not be connect AC generator;
5) One battery(bank) connect with multi inverters.
