Our project aims to develop an affordable and versatile device for testing and analyzing solar panels, batteries, and other voltage sources. The primary objective is to create a portable, cost-effective, and space-efficient device that can be used in various scenarios, including the evaluation of remote microgrids and specialized systems. The device will enable users to gather crucial information about the voltage-current relationship, voltage-power relationship, and other power characteristics of each test source across a range of load currents. One key aspect of the device is its configurability, allowing users to easily modify device parameters and components to accommodate different use cases. This includes supporting lower or higher power sources, adapting to sources with different characteristic curves, and accommodating a wide input source voltage range. By providing users with digestible and valuable data, the device will facilitate the characterization and design of diverse energy systems that utilize these energy sources
