1500V Modules

■
The recommended maximum parallel module configuration is Ifuse/Isc +1 parallels.
And the number of modules have something to do with system design parameters such
as current or power output.

■
Please refer to local regulations to determine the system wires size, type and temperature.
■
To prevent the cables and the connectors from overheating, the cross section of the
cables and the capacity of the connectors must be selected to suit the maximum system
short circuit current (The recommended cable cross section is 4mm2 for a single
module and if rated current of a connector is
higher than 10A). Please note that the upper
limit temperature of cable is 85°C, and that of the connector is 105°C. And all the cables
diameter that been used for wiring must reach at least 4 mm2.
■
The DC current generated by photovoltaic systems can be converted into AC and fed
into a public grid. As local utilities’ policies on connecting renewable energy systems
to their grids vary from region to region. A qualified system designer or integrator
should always be consulted. Building permits, inspections and approvals by the local
utility are generally required.
4.2 Earthing and Grounding
■
Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers,
flat washers and the like) is used to attach a listed grounding/bonding device, the
attachment must be made in conformance with the grounding device manufacturer’s
instructions.”
■
For grounding and bonding requirements, please refer to regional and national safety
and electricity standards. If grounding is required, use a recommended connector type,
or an equivalent, for the grounding wire.
■
If grounding is required, the grounding wire must be properly fastened to the module
frame to assure adequate electrical connection.
