CAUTION Indicates a situation where damage or injury could occur. If
it is not avoided, minor injury and/or damage to property
may result.
yThis product is intended for residential use only and should not be used for commercial or
industrial.
yBefore testing electrical parts inside the system, it takes at least 10-minute standby period of
time to complete discharging the system.
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 qualied 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 fullled 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, qualied 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 dispose of batteries in a re. The batteries may explode.
yDo not open or damage batteries. Released electrolyte is harmful to the skin and eyes. It may be

yA battery can present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries.
a) Remove watches, ring, or other metal objects.
b) Use tools with insulated handles.
c) Wear rubber gloves, boots and glasses
d) Do not lay tools or metal parts on top of battery.
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.
NOTE Indicates a risk of possible damage to the product.
yBefore making connections, please make sure the PV array open circuit voltage is within 1000 V.
Otherwise the product could be damaged.
yNever use any solvents, abrasives or corrosive materials to clean this product.
yDo not store on or place against any objects to the product. It may cause serious defects or
malfunction.
yBefore making a connection, make sure the PV switch on this product is switched off.
yThis unit is designed to feed power to the public grid only. Do not connect this unit to an AC
source or generator. Connecting the product to external devices could result in serious damage to
your equipment.
yServing of batteries should be performed or supervised by LG service person or trained installer.
yThe battery does not discharged when the load is under the certain level.
yThis product can cause current with a DC component. Where a Residual Current-operated
protective (RCD) or monitoring (RCM) device is used for protection in case of direct or indirect
contact, only an RCD or RCM of Type A (or type B) is allowed on the supply side of this product.
yThis product is designed to be installed indoor use only. Do not install this product outdoor.

Glossary
Terms Explanation
Azimuth In the Northern hemisphere, the azimuth angle indicates by how much
degrees the module surface deviates from a full south aspect. In the
southern hemisphere, it indicates the deviation from a full north aspect.
The azimuth angle is counted with positive values within the range from
south (0°) to west (90°) and it counted with negative values within the
range from south (0°) to east (-90°).
Tilt angle The tilt angle indicates by how much degrees the tilt of the module surface
deviates from the horizontal.
PV module The PV module refers to a panel designed to absorb the sun’s rays as a
source of energy for generating electricity.
PV array Technical device for the conversion of solar energy into electrical energy. All
serial and parallel installed and connected to PV modules of a PV system
are referred to as a PV array.
