Abstract This project work centered on construction of 12V/10A solar charge controller that is needed in photovoltaic system to safely charge regulate and discharge of sealed lead acid battery through DC load. Solar charge controller is devices that regulate solar photovoltaic power and prevent overcharging, over discharging or overflow of current that reduces the lifespan, durability and performance of the battery. The12v/10A solar charge controller was constructed using variable resistor, ...
Abstract This project work was embarked on the construction and determination of the efficiency of 12 volts DC fan using two N3055 transistor, 1kΩ variable resistors, resistors, breadboard, veroboard, 12 volts DC battery and connectors at Science Laboratory Technological Department, Federal Polytechnic Offa, Nigeria. This is always required to minimize, control or totally eliminate the power fluctuations received at the load end or consumer end that usually lead to the reduction of DC fan li...
