01 INTRODUCTION
GoodWe BT series bi-directional inverter is designed for both indoor and outdoor use, which could be
used with or without existing grid-tied inverter systems to store energy with batteries.
Energy produced from grid-tied inverters shall be used to optimize self-consumption, then charge
battery, exceed power from grid-tied system could export to grid. Loads will be supported in priority by
grid-tied system, then battery power, exceed consumption power will be drained from grid.
Note:
The introduction describes a general behavior of ET system.
The operation mode can be adjusted on GoodWe PV Master
APP depends on the system layout. Below are the general
operation modes for BT system:

1.2 SAFETY & WARNING
The BT series inverter 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 mainte-
nance, as any improper operation might cause personal or property damage.

SYMBOLS EXPLANTION
Caution!
Failing to observe a warning indicated in this manual may result in injury.
Danger of high voltage and electric shock!
Danger of hot surface!

1.1 OPERATION MODES INTRODUCTION
BT system normally has the following operation modes based on your configuration and layout
conditions.
Energy from grid-tied inverters optimize loads, then
charge battery, exceed power export to grid.
When grid power fails, battery will discharge to support
Back-Up Loads.
When energy from grid-tied inverters is weak, battery
discharge to support loads in priority, together with grid.
Battery could be charged by grid, and charge time/power
could be set flexibly on PV Master APP.
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.
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.

SAFETY WARNING
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).
Prohibit to insert or pull the AC and DC terminals when the inverter is running.
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

Do not open inverter cover or change any components without GoodWe’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 useless and warranty 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.
Battery negative(BAT-) on inveter side is not grounded as default design.
Connecting BAT- to EARTH are strictly forbidden.
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 s Off-Grid System Connection
Diagram in page 16.
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’.

2.3 MOUNTING
2.3.1 SELECT MOUNTING LOCATION
For inverter’s protection and convenient maintenance, mounting location for inverter should be
selected carefully based on the following rules:
Any part of this system shouldn’t block the switch and breaker to disconnected inverter from DC and
AC power.
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° (Figure 2.3.1-1)
