BLOCKING DIODES
Blocking diodes are typically placed between the battery and the PV Module output to prevent battery
discharge at night. WAAREE Modules do not contain a blocking diode when shipped from the factory. It is
recommended that a charge controller be used to prevent the batteries from being overcharged and
discharged at night.
Note: -
The non-use of blocking diode or any reverse current protection in battery operated system will void
all applicable warranties.
MAINTENANCE SAFETY
Safety instructions must be followed during maintenance of PV Modules. Any Maintenance work must be
performed by a certified installer/servicer to ensure system integrity and safety.
•
Do not pull the PV cables. Do not place/drop objects onto the PV Modules.
•
Do not damage, pull, bend or place heavy material on Junction box, cables & connectors.
•
Upon completion of any service or repairs, ask the installer/servicer to perform routine checks to
determine that the PV Modules are in safe and proper operating condition.
•
Do not stand or step on the Module.
•
Do not disassemble, modify or adapt the Module or remove any part or labeling installed/ pasted by the
manufacturer.
•
Do not drill holes in the frame; do not treat back sheet and front surface of the Module with paint and
adhesives.
•
Do not artificially concentrate light on the Module.
GENERAL SAFETY
•
Follow all permission, installation and inspection requirements.
•
Before installing Modules, contact the appropriate authorities to determine permissions,
installation, and inspection requirements which shall be followed.
•
Electrically ground Modules for all systems of any voltage.
•
If not otherwise specified, it is recommended that requirements of the latest National Electrical Code or
other national or international electrical standards be used.
•
Be sure that the construction or structure (roof, facade, etc.) where the Modules are being installed has
enough strength. For Modules mounted on roofs, special construction or structures may be required to
help provide proper installation. Both roof construction and Module installation design affects the fire
resistance of a building. Improper installation may contribute to fire hazards. Additional devices such as
ground fault detector, fuses, and disconnects may be required.
•
Do not use Modules of different specifications in the same system.
•
Only PV Modules with the same cell size should be connected in series.
•
Follow all safety precautions of other system components used.
•
Wiring and grounding method of the frame of arrays shall comply with national, regional and local
codes, laws and standards.
