sure to follow the safety recommendations of their manufactures.
These modules contain factory installed bypass diodes. If these modules are incorrectly connected to each other, the
bypass diodes or cable or junction box may be damaged.
Array Wiring
The term
“
array
”
is used to describe the assembly of several modules on a support structure with associated wiring.
Use copper wire that is sunlight resistant and is insulated to withstand the maximum possible system open circuit
voltage. Check your local codes for requirements.
Module Terminations
A junction box as terminal enclosure is equipped for electrical connections on RISEN modules. The modules are
equipped
with MC plugs as terminal enclosure. Use these MC plugs for electrical connections. Please contact your local dealer
with questions regarding other electrical connections for modules.
DIODES
Bypass Diodes
By having a bypass diode, the forced current will bypass the shaded module in a series circuit, thereby minimizing
module heating
and array current losses. Typically modules are supplied with a 12Amp diode which has r
epetitive peak forward
current 50A
and peak reverse voltage 40V
diode. For 12-volt systems and higher: Each solar module junction box has a diagram
illustrating
the proper direction for the by- pass diode to be installed between two of the terminal screws. When the solar
modules are connected
as individual series strings first, and then these strings are connected in parallel, bypass diodes should be used in each
junction box.
This is the simplest wiring arrangement for most installations. At a minimum the bypass diodes must have the
following electrical characteristics:
•
Rated Average Forward Current Above maximum system current at highest operating temperature.
MAINTENANCE
Some maintenance is recommended to maintain optimal output performance of solar cell modules. If the module
surface becomes dirty, it may cause reduction of output power. It is recommended to clean the surface with
water and soft cloth or sponge. A mild non-abrasive detergent may be applied for the persistent dirt. And it is also
recommended to
inspect the electrical and mechanical connections annually.
If you need electrical and mechanical inspection or maintenance, it is recommended to have the authorized professional
carry out
the inspection or maintenance to avoid the hazards of electric shock or injury.
The return of any modules will not be accepted by RISEN unless prior written authorization has been given by RISEN.
As part of our policy of continuous improvement, RISEN reserves the right to change product specifications
at any time without prior notice.
