1.1 Operation Modes Introduction
01 Introduction
The ES series, also called hybird or bidirectional solar inverters, apply to soalr system with
partcipation of PV, battery, loads and grid system for energy management. The energy produced
by PV system shall be used to optimize household, excess power charges battery and the
rest power could be exported to the grid. Testing to AS/NZS 4777.2:2020 for multiple phase
combinations has not been conducted
The battery shall discharge to support loads when PV power is insucient to meet self-
consumption needs. If battery power is not sucient, the system will take power from the utility
grid to support loads.
The preceding introduction describes the general operation
of the ES system. The operation mode can be changed
with the PV Master app based on the system layout. The
possible operation modes for the ES system are shown
below.
ES system normally has the following operation modes based on your conguration and layout
conditions.
Mode I
The energy produced by the PV system is used
to optimize self-consumption needs. The excess
energy is used to recharge the batteries, any
remaining excess is then exported to the grid.
Mode III
When the grid fails, the system will
automatically switch to back-up mode. The
back-up loads can be supplied by both PV and
battery energy.
Mode II
When there is no PV, and the battery is
sucient, it can supply the load together
with grid power.
Mode IV
Battery could be charged by grid, and
charge time/power could be set to various
options on the PV Master App.

1.2 Safety and Warning
The ES series of inverters from GoodWe Technologies Co., Ltd. (also called GoodWe) strictly
complies with related safety rules for product design and testing. Please read and follow all of
the instructions and cautions appearing on the inverter or in the User Manual during installation,
operation and maintenance, as any improper operation might cause personal injury or property
damage.
Symbol Explanation
Danger - high voltage and electric shock!
Caution!
Failure to observe any warnings contained in this manual may result in injury.
Danger - hot surface!
The components of the product can be recycled.
This side up! This package must always be transported, handled and stored in such
a way that the arrows always point upwards.
No more than six (6) identical packages being stacked on each other.
Products shall not be disposed as household waste.
5min
Fragile - The package/product should be handled carefully and never be tipped over
or slung.
Refer to the operating instructions.
Keep dry! The package/product must be protected from excessive humidity and
must be stored under cover.
This symbol indicates that you should wait at least 5mins after disconnecting the inverter
from the utility grid and from the PV panel before touching any inner live parts.
CE mark.

01 Introduction User Manual V1.1-2022-01-05
Any installation or operations on the inverter must be performed by qualied electricians
in compliance with standards, wiring rules and the requirements of local grid authorities or
companies (such as AS 4777 and AS/NZS 3000 in Australia).
Before any wiring connection or electrical operation on inverter, all battery and AC power
must be disconnected from inverter for at least 5 minutes to make sure inverter is totally
isolated to avoid electric shock.
The temperature of inverter surface might exceed 60℃ during operation, so please make
sure it has cooled down before touching it, and make sure the inverter is out of reach of
children.
Do not open the inverter's cover or change any components without manufacturer's
authorization, otherwise the warranty commitment for the inverter will be invalid.
Usage and operation of the inverter must follow instructions in this user manual, otherwise
the protection design might be impared and warranty commitment for the inverter will be
invalid.
Appropriate methods must be adopted to protect inverter from static damage. Any damage
caused by static is not warranted by manufacturer.
PV negative (PV-) and battery negative (BAT-) on inverter side is not grounded as default
design. Connecting PV- to EARTH are strictly forbidden.
PV modules used on the inverter must have an IEC61730 class A rating, and the total open-
circuit voltage of PV string/array is lower than the maximum rated DC input voltage of the
inverter. Any damage caused by PV over-voltage is beyond warranty.
The inverter, with built-in RCMU, will exclude possibility of DC residual current to 6mA, thus in
the system an external RCD (type A) can be used(≥30mA).
In Australia, the inverter internal switching does not maintain neutral integrity, which must
be addressed by external connection arrangements like in the system connection diagram for
Australia.
In Australia, output of back-up side in switchbox should be labeled on "Main Switch UPS
Supply".The output of normal load side in switch box should be labeled "Main Switch Inverter
Supply".
