Power grids in locations such as Columbia Colombia are often unstable which results in unreliable power sources. Battery-grid hybrid systems can be used to alleviate the power instability of a region, often using renewable sources to charge the battery. A mobile power station could provide support for a variety of applications that require uninterrupted electricity. In 2017, a cart with solar panels was developed to provide a dependable power supply for a 3-D printer. In 2019,  the power system for the 3-D printer became its own system, designed from the ground up. The initial design of this system included a custom cart for switching between power sources, increased ease of use and assembly, and the ability to fail gracefully without power. Due to the COVID-19 pandemic, work on the 2019 version of the cart was not completed.

The goal of this project is to enhance the progress made during the 2019 academic year. Two additional power sources are to be included to supplement the solar power, while also being cognizant of limited supplies and resources in the area. The cart must be capable of withstanding the effects of transport and environmental abuse. The expected result is a functioning prototype cart with instructions for assembly, disassembly, testing, and regular use.
