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 Kenworth T680 tractor with a sleeper cab and full or 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 Kenworth T680 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 Kenworth T680 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-K-400-17): 400W Kenworth T680 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 Kenworth T680 Fairing SuperFlex Solar Panel, designed for commercial transportation.
