To avoid performance losses in series circuits, ensure that
all modules have the same tilt and orientation.
Your solar professional will be able to determine the best
tilt angle for your location.
ELECTRICAL INSTALLATION
To ensure proper system operation and maintain the
warranty, be careful to observe the correct cable
connection polarity when connecting the modules to a
battery or to other modules. If not connected correctly, the
bypass diode(s) could be destroyed.
All PV modules must be grounded by electrical connection
of the module frames to ground.

Bypass Diodes
The junction boxes used with Sunlink PV modules contain
bypass diodes wired in parallel with the PV cell strings.
In the case of partial shading, the diodes bypass the
current generated by the non-shaded cells, thereby
limiting module heating and performance losses.
Bypass diodes are not overcurrent protection devices.
Bypass diodes divert current from the cell strings in the
event of partial shading.
In the event of a known or suspected diode failure,
installers or maintenance providers should contact the
company the PV modules were purchased from.
Never attempt to open the junction box of a PV module
yourself.
Care must be taken to arrange the system ground so that
the removal of one module from the circuit will not
interrupt the grounding of any of the other modules.In the
