ANNEX C: INSTALLATIONS USING MODULE LEVEL POWER ELECTRONICS
This section is applicable to all Canadian Solar standard
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.
