ANNEX B: INSTALLATIONS USING MODULE LEVEL POWER ELECTRONICS
This section is applicable to CS6R-MB-HL and all Canadian
Solar monofacial module types referred to in this
installation manual.
Module-level power electronics (MLPE) are devices that
can be incorporated into a solar system to improve its
performance in certain conditions (especially where shade
is present) and to reduce shock hazard for emergency
responders. MLPE devices can be supplied as a ‘retro-fit’
system made by third-party supplier.
Module certification testing does not include MLPE devices.
When installing MLPE devices with Canadian Solar
modules, follow the instructions of the MLPE supplier and
the specific requirements given below. Ensure electrical
parameters and limitations of the MLPE devices and the
Canadian Solar modules are suitable for one another.
Failure to comply with these instructions will void the
Canadian Solar warranty.
INSTALLATION
When choosing to mount the MLPE device to the module
frame, follow the MLPE supplier instructions to ensure
optimal mounting of the MLPE device and prevent any
slippage during operation.
Canadian Solar recommends the MLPE device be installed
close to a corner of the module frame.
When choosing to mount the MLPE device to the mounting
structure, please refer to the instructions provided by the
MLPE supplier.
Do not
cover the module nameplate or junction boxes
when installing the MLPE devices on the rear of the
modules.
Do not
use frame mounting holes to install the MLPE
device.
Do not
drill extra holes in the frame to install the MLPE
device.
The distance between the MLPE device and the module
backsheet should be larger than 20mm.
