INTRODUCTION
DB Power Electronics has pioneered the Photovoltaic Inverter Systems since 1992
with Bi-directional grid connect technology and custom built product solutions for
critical applications.
The uniqueness of bi-directional inverter technology is that, in absence of sunlight it
takes power from the Grid for charging the batteries and supports your lighting
system. Also, it feeds the power to the Grid, when there is excess power available,
from the PV arrays.
Ranging from a smallest power pack to large solar farms, the generated
photovoltaic power fed to the grid to manage the grid parity situations. From the
remotest location to the largest building integrated photovoltaic systems (BIPVs),
DB Power holds the market presence with one of the largest installation base across
the country. These installations are catering needs of the customers for more than a
decade. In-house, State-of-the-art design capability and indigenous technology
are the core competence of DB Power in the field of solar photo voltaic .

SINGLE LINE DIAGRAM
Bhaskar PCU is Single/Three phase output, bi-directional inverter system. Solar Photovoltaic Panels are used to convert Solar energy
into electrical energy, These Solar PV panels produce DC power. PCU operates in parallel to the grid utility. This DC power is then
used to charge the batteries through charge controller. Additional energy will be exported to the grid via the same bi-directional PCU
system. Whenever grid voltage and frequency goes beyond the operating range, the same will be disconnected from the grid. PCU
will supply the continuous power to load without any interruptions.
