24W SemiFlex Solar Panel with Built-In Charge Controller for Thermo King Precedent TRU (R3-7F13.7VTK)

Product Details:

• Description

  Keep your fleet running smoothly with the 24W SemiFlex Solar Panel, designed for commercial transportation. This maintenance-free solution supports TRU batteries, helping fleet managers prevent starting battery failures and reduce downtime.

  The Integrated PowerBoost Charge Controller maximizes solar output for 12V battery systems, extending battery life, preventing overcharging, and reducing maintenance expenses.

  The panel attaches easily to the metal frame of the TRU with four self-tapping screws. Older Thermo King units may need rubber feet as spacers between the panel and metal frame to avoid height obstructions. (Screws and spacers are not included).

  The 24W SemiFlex Solar Panel helps fleets stay on schedule by reducing jumpstarts, extending battery life, and cutting maintenance costs—improving reliability, efficiency, and overall performance.
