Solar-electric e-reefer solutions
The solar-electric solution sees the trailer’s refrigeration unit powered by a lightweight battery pack that is fitted underneath the trailer’s chassis. The pack is expandable according to the length of the temperature -controlled run time required and is primarily charged by electricity from the grid via 3-phase supply, typically at a loading bay.
However, charging of the battery is supplemented, particularly in the summer months, by a ‘solar array’ that is fitted to the roof of the trailer and which continuously feeds power into the battery for reduced reliance on charging from the grid.
The solution may achieve upto 20 hours of temperature control with a deep freeze set-point.
To ensure uninterrupted temperature-controlled performance, the system can intelligently access the diesel engine as a backup in the event of battery power failure.
The system offers real-time monitoring of energy use, battery status and refrigeration operation.
The system is retrofit-ready so that it can be installed on both new and existing refrigerated trailers. This effectively enables fleet operators to shift towards zero-emission refrigeration without needing to acquire new refrigerated trailers.
What’s more, installation of the system can be done quickly so that downtime is minimal.
