Safety Warnings - Goodwe ET Series User Manual

Safety warnings

Any installation or operations on the inverter must be performed by qualified 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).
Never insert or remove the AC or DC connections when the inverter is running.
Before any manipulation in the inverter connection area, it is necessary to turn off all power from the DC and
AC sides. After that, you must wait 5 minutes before starting work with the inverter.
The temperature of the inverter surface can exceed 60°C during operation. 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 cover or change any components without the manufacturer's authorization.
Otherwise, the warranty for the inverter will be invalid.
The usage and operation of the inverter must follow the instructions in this User Manual. Otherwise, the
protection design might be impaired and the warranty for the inverter will be invalid.
Appropriate methods must be adopted to protect the inverter from static electricity damage. Any damage
caused by static electricity is not warranted by the manufacturer.
The negative (PV-) input of the inverter is not grounded. It is prohibited to connect the PV- or BAT- inputs to
the ground.
PV panels shall comply with class A according to IEC61730. The total idle voltage of the string, must not exceed
the permitted maximum DC input voltage of the inverter. Exceeding the maximum permitted DC voltage will
cause the changer to be destroyed and the warranty to be lost.
When exposed to sunlight, the PV array generates dangerous high DC voltages. Please operate the inverter
according to these instructions, or danger to life may result.
The inverter has a built-in RCMU protector that monitors leakage currents on the DC side up to 6mA, when
using an external protector, use an RCD/A type protector
In Australia, the output of the backup side in the switch box should be labeled "Main Switch UPS Supply". The
output on the normal load side in the switch box should be labeled "Main Switch Inverter Supply".
