Product Features
This product is intended to store direct current (DC) electricity generated from photovoltaic (PV) to the
connected Lithium-Ion Battery, and convert direct current (DC) electricity from the connected battery to
alternating current (AC) electricity and feed this into the power grid.
AC Grid
PV array
Smart Meter
Distribution Box
(AC circuit breaker)
PCS Battery
The electricity generated from a PV array can be stored to the connected battery or sold to energy supply
companies.
yDC-Coupled ESS
LG ESS can achieve higher system efciency due to simpler power conversion process.
yThree-Phase Connection
3-phase connection secures phase balancing.
ySmart Management
With built-in Smart PMS, it analyses PV generation and load consumption and implements to charge and
discharge immediately. Also it monitors main system & battery conditions to maintain its stable condition
always.
yWeb-monitoring Service

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.
