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

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
