This document describes a revolutionary portable refrigerated cooler and freezer called the Port-a-Kold that can operate off-grid using solar power. It has high insulation modular panels and uses various technologies like heat recovery and solar panels to operate with zero energy. The Port-a-Kold can be used in remote locations for industries like food, pharmaceuticals, and emergencies. It provides a portable cold storage solution that operates independently without needing electricity from the grid.
