PURPOSE DESCRIBED IN THIS INSTALLATION MANUAL.

WARNING

yThere is high possibility of electric shock or serious burns due to the high voltages in power

conditioning circuits. yHigh voltages on AC and DC cables. Risk of death or serious injury due to electric shock. yA potentially hazardous circumstance such as excessive heat or electrolyte mist may occur due to

improper operating conditions, damage, misuse and/or abuse. yThis product have potential danger such as death or serious injury by re, high voltages or

explosion if appropriate precautions are not read or fully understood. yDo not place ammable or potentially explosive objects near the product. yDo not place any kind of objects on top of the product during operation. yAll works on the PV modules, power conditioning system, and battery system must be carried out

by qualied personnel only.

yElectrical installations must be done in accordance with the local and national electrical safety

standards. yWear rubber gloves and protective clothing (protective glasses and boots) when working on high

voltage/high current systems such as PCS and battery systems. yThere is a risk of electric shock. Do not remove cover. There is no user serviceable parts inside.

Refer servicing to qualied and accredited service technician.

yElectrical shock hazard. Do not touch uninsulated wires when the product cover is removed. yIn the event of fault, the system must not be restarted. Product maintenance of repairs must be

performed by qualied personnel, or personnel from an authorized support center.

yIf the connected batteries are not LG battery, not only the batteries but also the PCS is not

guaranteed by LG Electronics.

Indicates a potentially dangerous situation. Death or serious injury may result if appropriate precautions are not taken.

Getting Started

Indicates a situation where damage or injury could occur. If

CAUTION

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

toxic.

it is not avoided, minor injury and/or damage to property may result.

Getting Started

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.

Getting Started

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

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. yThis document is for your reference only. Read the installation manual on the website below.

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.
