yThe contents included in this box are power conditioning system and its accessories, and the
entire weight is very heavy. Serious injury may occur due to the heavy weight of the package with
PCS and accessories. Therefore, special care must be taken in handling. Make sure to have at least
two persons deliver and remove the package.
yDo not use the damaged, cracked or frayed electrical cables and connectors. Protect the electrical
cables from physical or mechanical abuse, such as being twisted, kinked, pinched, closed in a door
or walked upon. Periodically examine the electrical cables of your product, and if its appearance
indicates damage or deterioration, discontinue use of this product, and have the cables replaced
with an exact replacement part by a qualied personnel.
yEnsure that you connect the earth ground wire to prevent possible electric shock. Do not try to
ground the product by connecting it to telephone wires, lightning rods or gas pipes.
yThe product should not be exposed to water (dripping or splashing) and no objects lled with
liquids, such as vases, should be placed on the product.
yTo prevent re or electric shock hazard, do not expose this production to rain or moisture.
yDo not block any ventilation openings. Ensure reliable operation of the product and protect it
from over heating. The openings shall never be blocked by placing any object on this product.
yThe temperature of metal enclosure may be high during operation.
yIn order to avoid radio-interference, all accessories (like a energy meter) intended for connection
to the product shall be suitable for use in residential, commercial and light-industry areas. Usually
this requirement is fullled if the equipment complies with the class B limits of EN55022.
yThe product must be disposed of according to local regulations.
yThe electrical installation of this unit must only be performed by LGE service person or trained
installer, qualied to install PCS.
yIf the AC circuit breaker is turned off and the PCS is not operated for a long time, the battery may
be overdischarged.
yConnect the DC+ and DC- cables to the correct DC+ and DC- terminals on the product.
yDanger of damaging the PCS by overload. Only connect the proper wire to DC terminal block.
Refer to the installation wiring diagram for details.
yDo not step on the product or the product package. The product may be damaged.
yDo not leave the ESS in the Fault standby state for a long time because of the battery discharge
may occur during the long standby state.
yIf the battery fault occurs immediately after starting PCS it means Battery failure. Check the
battery SOC also voltage and fault information, and turn off the power of the ESS until service
action is taken.
yIf the battery SOC is low, the battery may charge from the grid for self-protection. (Emergency
Charging) This function is to prevent shutdown of the ESS, deep discharge and failure of the
battery. An Emergency Charge is not an ESS fault.
yIf the battery SoC is too low during the backup operation of a power outage, the PCS will only
charge the battery from Solar PV. It means no power is supplied to the home load.
Emergency Charging(backup) will charge the battery up to the backup SoC level that you set
(30% by default). Emergency Charging(backup) is not an ESS fault.
yInstall the PCS where the noise from the PCS will not inconvenience the neighbors. Failure to do
so may result in conict between neighbors.
