Optimized to deliver more power faster, Carrier Transicold’s newest solar charging system for transport refrigeration unit (TRU) batteries features an innovative design that conveniently fits on top of the transport refrigeration unit TRU.
The new TRU-Mount Solar Charging System delivers 2.0-amp power delivery by combining ultra-pure silicon cells with a high-performance charge controller.
“With a significantly smaller footprint than our prior solar panels, the new system provides up to 18% greater power delivery for faster, more complete charging of a 12-volt TRU battery, helping ensure uninterrupted performance,” says Jason Forman, associate director, sales and marketing, performance parts, Carrier Transicold.
The innovative panel design provides a custom fit on the narrow, curved top surface of Carrier Transicold X4 and X2 series trailer refrigeration units and Vector 8000 and 6000 series units. The charge controller is integral to the panel, which simplifies installation.
“The location of the TRU-Mount panel has multiple advantages,” Forman says. “The lower positioning on the TRU makes it less susceptible to overhead scrapes that can affect trailer-top-mounted panels. Unlike some competitive units, Carrier’s TRU-Mount system is not suspended over the exhaust path, helping to avoid efficiency losses that occur when solar cells are exposed to high temperatures. The system also conveniently stays with the TRU if the TRU is removed and reinstalled on another trailer.
The panel uses three engineered layers to maximize strength and efficiency. The light-trapping upper layer is scratch-, impact- and weather-resistant. The middle layer is composed of uncut monocrystalline cells that maximize output and minimize power loss from intermittent shading. The copper bottom layer serves as a heat sink that keeps the panel cooler for greater efficiency.
