Maximum current input DC/String:33A Maximum efficiency:>98.1%
Power connection : 3-phase
We may take any other reputed make with efficiency> 95%.
Mounting Structures Panels shall be mounted on galvanized frames inclined at 30.3degrees to the
South. The structure is designed in such a manner that module can be replaced eas
to install and service in future. The frames will be supported by angle legs of
Suitable length stop provide the pre-determined inclination. All fasteners, nut
and bolts are made of Stainlesssteel-SS304 5.4.6 PCC. The structures shall be
pre-engineered to meet special requirements of placing the modules on the
Corrugated roof tops.
FOUNDATION BASE: The legs of the structures made with GI angles
are made of fixed and grouted in the PCC foundation Columns made with
1:2:4 cement concrete.
Electrical Accessories Cables will conform to IS694 and shall be of 650V/1.1k V grade.
Inter connections, array to junction boxes,
junction boxes to DCDB, DCDB to PCU
etc will be selected to keep voltage drop and
losses to the minimum. The bright annealed
99.97% pure bare copper conductors offer low
Conductor resistance,

Result in lower heating thereby increasing cable life and efficiency. These
Wires are insulated with a special grade PVC compound formulated and
Manufactured in-house.
Working voltage: up to 1100 V Temperature range:-15 deg Cto+70degC
Sizes: Suitable sizes
Color codes: Red, Yellow, Black, Blue, Green
Combiner DC combiner
Energy Meter The Inverter shall have a built-in meter that tracks energy production and
Display sit on a small LED screen. The display can be used to determine
Real-time production, daily production, and yearly production. For more
sophisticated analysis and visual data management, Solar Access modules
Can be included.
Remote Monitoring System(Optional) The web box continuously records and stores all avails able data of
about 50 inverters in real time, in addition the inverter parameter scan be
requested and modified. It provides you with various modern data
processing options for professional data Management .These are save din
conventional CSV or XML file formats. The ability to exchange data by
FTP allows you to easily transfer these values to your. To your PC you can
Just as easily use an SD card to save your data any such feature of remote
monitoring shall be made available through additional costs.
Stringing Design 8 strings of 17 panels each, however a detailed engineering might Change
the stringing design. Incase Inverter configuration needs any modifications,
based on its availability, the string layout may be Modified accordingly.

E. Installation Details
Area required:
The Total Area required for the System Installation shall be approx 2800 sq feet, without any shades, facing south.
Structural Anchoring:
Panels shall be mounted on galvanized frames inclined at 30.3 degrees to the south or 6 degree in movable structure. The structure is designed in such a m
be replaced easily and in line with site requirements and it is easy to install and service in future. The frames will be Supported by angle legs of
suitable lengths to provide the pre-determined inclination. All fasteners, nutand bolts are made of Stainless steel-SS304 5.4.6 PCC.
Foundation Base:
The legs of the structures made with GI angles are made of fixed and grouted in the PCC foundation columns made with 1:2:4 Cement concrete.
Actual frame and other structural dimensions will be determined during a more detailed site visit by specialists during full design phase.
Inverter Installation
This space provides sample accessibility and good air circulation. The inverter is available in IP54housing, however, an enclosed Space has to be
Provided for the same. Actual installation location and methods will be determined during full design phase.
Electrical
Proposed fire hoses haft will be used for running electrical cables down to the electrical panel room. A detailed electrical design with Single-line
Diagram and specifications will be prepared during full design phase after receiving the PO, for the client’s approval.
