Product Overview - LG LGES-5048 User Manual

Safety Warning
Installation and operation of the inverter must be performed by qualified electricians, in compli-
ance with all local standards, wiring rules and requirements of local grid authorities, e.g. AS 4777
and AS/NZS 3000 in Australia.
Before any wiring connection or electrical operation on the 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 operation, so please 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's cover or change any components without manufacturer's autho-
risation, otherwise the warranty commitment for the inverter will be invalid.
03
Usage and operation of the inverter must follow the instructions in this user manual,
otherwise the protection design might be impaired and 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 manufacturer.
PV negative (PV-) and battery negative (BAT-) on inverter side is not grounded as default
design. Connecting PV- to EARTH is strictly forbidden.
PV modules used on the inverter must have an IEC61730 class A rating, and the total
open-circuit voltage of PV string/array must lower than the maximum rated DC input voltage
of the inverter. Any damage caused by PV over-voltage is beyond warranty.
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 system connection diagram
for Australia on page 16.
In Australia, output of back-up side in switchbox should be labeled on "Main Switch UPS
Supply".The output of normal load side in switch box should be labeled "Main Switch Invert-
er Supply".
