Last month we started a new project together with students at Brunel University London. The aim is to build a portable off grid refrigerating unit. Fifteen panels, eight batteries and well insulated refrigerated trailer will help African farmers to store their locally produced food.

The PV panels are all attached to the trailer There are three panels already mounted on the roof, and the remaining twelve will create wings (six panels on each side) that can be folded down when the unit needs to be moved.

System details:

  • 15 x 300Wp modules
  • 1 x 3000W inverter
  • 8 x lead batteries
  • 1 x battery controller

All batteries, inverter and the battery controller are already installed inside the cabinet and connected.

Once in situ, the stored electricity from the powerful African sunshine will be used to power the refrigeration units bringing well needed chilled storage for their rich local produce. Produce such as avocados, artichokes, peppers, raspberries and blueberries are in abundance in central African countries and a large scale roll-out of this instant, off-grid, portable, renewable storage in this versatile trailer would potentially bring great value to these developing countries.
