Abstract
This paper introduces a 420-liter freezer powered by a PV solar system that works without spare batteries. Hence, it provides a green solution for stand-alone applications in remote areas and in places with electricity shortage. To this end, an AC compressor is replaced with a DC compressor to run by the PV panels using a controller that can allow for easy start-up, maximum power tracking, and power management for the system. The designed prototype enabled the freezer to run with attested operation. There are no issues concerning the compressor starting if the speeds is lowered. The system can remain operational even during low solar irradiance days. In addition, an optimum utilization of the photovoltaic energy can be accomplished.
