Specifications: Voltage: 33.6V Current: 11.6A Open Circuit Voltage: 40.5V Short Circuit Current: 12.6A ### Applications: * EPU battery and starting battery management for a Freightliner Cascadia tractor with a sleeper cab and mid-roof fairing. ### Specifications: * Voltage: 33.6V * Current: 11.6A * Open Circuit Voltage: 40.5V * Short Circuit Current: 12.6A ## Product Details: * Description Keep your fleet running smoothly with the 400W Freightliner Cascadia Mid-Roof Fairing SuperFlex Solar Panel, designed for commercial transportation. This maintenance-free solution reliably charges EPU and vehicle starting batteries simultaneously, helping fleet managers reduce idle time. Paired with a commercial maximum power point tracking (MPPT) charge controller, the panel maximizes solar output to battery systems, extending battery life, preventing overcharging, and reducing maintenance costs. The Place & Pull double-release liner enables quick, damage-free installation by minimizing panel flex, a common issue with other semi-flexible designs. This protects the high-efficiency Maxeon monocrystalline cells, ensuring exceptional power output and long-term durability. With an integrated edge seal, the panel eliminates the need for external edge taping, reducing installation time while ensuring a clean, professional finish that withstands harsh conditions. The 400W Freightliner Cascadia Mid-Roof Fairing SuperFlex Solar Panel helps fleets reduce diesel consumption and emissions, increase battery life, and cut operating costs—improving reliability, efficiency, and overall performance. Kit Options: 30ft. Wiring Harness Kit (CTK-FM-400-17): 400W Freightliner Cascadia Mid-Roof Fairing SuperFlex Solar Panel with Integrated Edge Seal Charge Controller with 30ft. Wiring Harness Benefits: Easy installation with integrated edge seal and Place & Pull double-release liner   Pairs with MPPT charge controller for optimized charging and battery safety Rugged, self-cleaning surface   High-efficiency Maxeon cells for maximum power output  Designed, engineered and assembled in the USA Tested to meet or exceed performance standards IV Curve #### Description Keep your fleet running smoothly with the 400W Freightliner Cascadia Mid-Roof Fairing SuperFlex Solar Panel, designed for commercial transportation.
