CS6P-260 |265P-SD Canadian Solar‘s SmartDC module features an innovative integration of Canadian Solar’s module technology and SolarEdge’s power optimization for grid-tied PV applications. By replacing the traditional junction-box with a SolarEdge power optimizer, the SmartDC module optimizes power output at module-level. With this feature, the SmartDC module can eliminate the module-level mismatch and decrease shading losses. Furthermore, the SmartDC module provides module-level data to minimize operational costs and allow effective system management.
KEY FEATURES Harvest up to 25% more energy from each module · Maximizes power from each individual module against potential mismatch risk · Decreases shading losses Easy installation, simple system design · Integrated smart solution, no need to add other accessories · Enhances the shading tolerance

4.0 UNPACKING AND STORAGE
· Do not carry the modules on your head.
PRECAUTIONS · If modules are stored in an uncontrolled environment for less than 3 months, extra precautions should be taken to prevent connectors from being exposed to moisture or sunlight. · Unpack module pallets carefully, following the steps shown on the pallet. Unpack, transport and store the modules with care.
· Do not leave modules unsupported or unsecured. · Do not use sharp instruments on the modules.
