# Solar Trailer Reefers Sunswap Delivers Endurance Reefer Units to Wickham Freight Lines By Amy Duong | Written with AI assistance | Published 2026-10-27 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/solar-trailer-reefers References: [electrek.co](https://electrek.co/2026/10/25/battery-electric-solar-powered-reefer-units-reach-their-first-customers)  Sunswap is bringing [battery-electric, solar-powered](https://www.trendhunter.com/trends/tracked-solar-forklifts) trailer reefers to Australia, where Wickham Freight Lines has taken delivery of the first regular-production unit. The Endurance [trailer refrigeration unit](https://www.trendhunter.com/trends/fuel-saving-trailer-aerodynamics), or TRU, keeps food and pharmaceuticals cold without a diesel generator, replacing a trailer power source that can keep running even when the truck is electric. Wickham bought the Endurance after a summer trial on its Sydney-to-Brisbane route and back. The out-and-back run spanned 1,670 km and lasted more than 30 hours. It ended with over 65% battery capacity still available, showing that the system can handle long [cold-chain duty](https://www.trendhunter.com/trends/Recycled-cold-chain-packaging) without refueling a separate engine. Australia's first regular-production solar reefer delivery turns trailer cooling from a diesel-powered attachment into an electrified fleet asset. Keeping the refrigeration system on battery power cuts generator fuel burn and also reduces trailer noise and local exhaust around delivery areas.
