Carrier Transicold’s newest solar charging system for transport refrigeration unit batteries features an innovative design that conveniently fits on top of the unit. The new TRU-Mount Solar Charging System delivers 2.0-amp power delivery by combining ultrapure silicon cells with a high-performance charge controller, according to the company.

“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,” said Jason Forman, associate director of sales and marketing for performance parts at Carrier Transicold.

Solar panels can also help conserve fuel by minimizing the need to run the TRU engine to charge the battery. The 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, simplifying installation.

The panel uses three engineered layers: the light-trapping upper layer, which is scratch-, impact- and weather-resistant; the middle layer, which is composed of uncut monocrystalline cells that maximize output and minimize power loss from intermittent shading; and the copper bottom layer, which serves as a heat sink that keeps the panel cooler for greater efficiency.

The new TRU-Mount Solar Charging System is now available for field installation and will be offered as a factory-installed option later this year.
