Note:
The introduction describes a general working situation of
the LGES system. The operation mode can be adjusted on
LGES PV Master App up to the system layout. The general
operation modes are as below:
01 INTRODUCTION
LGES-5048 is a hybrid or bidirectional solar inverter, applicable to solar systems connected to the
utility grid and LG Energy Solution RESU 48V batteries.
The energy produced by the PV system is used to power household loads, charge the battery,
and export excess energy to the utility grid. When household loads exceed PV production, the
battery is discharged to support the loads and minimize utility grid import.
With the optional addition of remote control, such as Virtual Power Plant (VPP) participation, the
inverter and battery combination can further optimise energy usage according to price signals.
The energy produced by the PV system is used to
optimise self-consumption. The excess energy is used to
recharge the batteries, the rest is exported to grid.
When grid fails, the system automatically switches to
Back-Up mode. The Back-Up load can be supported by
PV and battery.
Battery could be charged by grid, and charge time/power
could be set on LGES PV Master or remotely controlled.
When there is no PV, and the battery is sufficient, it can
supply the load together with grid power.
LGES system normally has the following operation modes based on your configuration and layout.
Mode Ⅰ Mode Ⅱ
Mode Ⅲ Mode Ⅳ
1.2 Safety & Warning
LGES-5048 from LG Energy Solution Ltd strictly complies 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. Improper operation might cause
personal or property damage.
Caution!
Failure 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 way as the arrows always point upwards.
Danger of hot surface!
No more than six (6) identical packages being stacked on each other.
Products should not be disposed as household waste.
Fragile - 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.
This symbol indicates that you should wait at least 5mins after disconnecting the
inverter from the utility grid and from the PV panel before touching any inner live
parts.

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.
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".

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 from disconnecting the inverter
from DC and AC power.
Rule 1. Inverter should be installed on a solid surface, where it is suitable for inverter's dimensions
and weight.
Rule 2. Inverter should be installed vertically or lie on a slope by a max of 15°.
