TABLE OF CONTENTS
1.1 OPERATION MODES INTRODUCTION
The ES series inverters of Jiangsu GoodWe Power Supply Technology Co., Ltd. (hereinafter called as
GoodWe) strictly comply with related safety rules for product design and testing. Please read and
follow all the instructions and cautions on the inverter or user manual during installation, operation or
maintenance, as any improper operation might cause personal or property damage.
GoodWe ES series, also called hybrid or bidirectional solar inverters, apply to solar system with
participation of PV, battery, loads and grid system for energy management.
The energy produced by PV system shall be used to optimize self-consumption, excess power charge
battery and the rest power could be exported to the grid.
Battery shall discharge to support loads when PV power is insufficient to meet self-consumption. If
battery power is not sufficient, the system will take power from grid to support loads.
ES system normally has the following operation modes based on your configuration and layout conditions
1.2 SAFETY & WARNING
• SYMBOLS EXPLANATION
INTRODUCTION01
Caution!
Failing to observe a warning indicated in this manual may result in injury.
Danger of high voltage and electric shock!
Components of the product can be recycled.
This side up! The package must always be transported, handled and stored in such a
way that the arrows always point upwards.
Danger of hot surface!
No more than six (6) identical packages being stacked on each other.
Product should not be disposed as household waste.
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.
Inverter will be touchable or operable after minimum 5 minutes of being turned off or
totally disconnected, in case of any electrical shock or injury.
CE Mark
Note: the introduction describes a general behavior of ES
system. The operation mode can be adjusted on GoodWe
PV Master APP based on the system layout. Below are the
general operation modes for ES system:
The energy produced by the PV system is used to
optimize self-consumption. The excess energy is used to
recharge the batteries, then exported to grid.
Mode Ⅰ
When there is no PV, and the battery is sufficient , it can
supply the load together with grid power.
Mode Ⅱ
When grid fails , the system automatically switches to
Back-Up mode. The Back-Up load can be supported by
PV and battery.
Mode Ⅲ
Battery can be charged by grid, and charging
time/power can be set flexibly on PV Master APP.
Mode Ⅳ

INTRODUCTION INTRODUCTION
• SAFETY WARNING
1.3 PRODUCT OVERVIEW
Any installation and operation on inverter must be performed by qualified electricians, in compliance
with standards, wiring rules or requirements of local grid authorities or companies (like AS 4777 and
AS/NZS 3000 in Australia).
Before any wiring connection or electrical operation on inverter, all DC 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 working, so please make sure it
is cooled down before touching it, and make sure the inverter is untouchable for children.
Usage and operation of the inverter must follow instructions in this user manual, otherwise the
protection design might be useless and warranty for the inverter will be invalid.
PV negative (PV-) on inverter side is not grounded as default design.
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, output of Back-Up side in switchbox should be labeled ‘Main Switch UPS supply’,
the output of normal load side in switch box should be labeled ‘Main Switch Inverter Supply’.
Do not open inverter cover or change any components without GoodWe’s authorization,
otherwise the 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 GoodWe.
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.
In Australia, the inverter internal switching does not maintain neutral integrity, which must be
addressed by external connection arrangements like in the Off-Grid System Connection
Diagram in page 16.

2.3 MOUNTING
Rule 1. Inverter should be installed on a solid surface, where is suitable for inverter’s dimensions and
weight.
Rule 2. Inverter installation should stand vertically or lie on a slop by max 15° (Pic 1)
Rule 3. Ambient temperature should be lower than 45℃
Rule 4. The installation of inverter should be protected under shelter from direct sunlight or bad
weather like snow, rain, lightning etc. (Pic 2)
Rule 5. Inverter should be installed at eye level for convenient maintenance.
Rule 6. Product label on inverter should be clearly visible after installation.
Rule 7. Leave enough space around inverter following the values on pic 3.
