INTRODUCTION
• 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).
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 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.
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 backup 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’.
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.
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 on page 16.
