A Mobile Photovoltaic-Battery System for Off-Grid Applications

This paper addresses the implementation of photovoltaic (PV) arrays and battery chargers to provide reliable electricity access for remote and off-grid locations. The proposed system comprises a PV array, a maximum power point tracker (MPPT), DC-DC converters, an inverter, and batteries. This system provides DC power for irrigation pumps and LED lighting. These loads are powered by a 12V DC battery bank, which stores the extracted solar energy from the PV array. Moreover, the device is designed to have a universal-serial-bus (USB) port that can be used for charging electronic devices. The design and implementation procedures for all components are included in this paper. Experimental results from the final product are also presented and discussed.
