Abstract :
Along with the increasing need for electrical energy and technological
developments, where the electricity source from PLN is used as the main power
source in a house. In one condition, the source of electrical energy from PLN is
not always continuous in its distribution. The manual transfer of electricity can be
time-consuming which can be detrimental to the agency. Therefore, an automatic
solar cell transfer operating tool was made, namely ATS (Automatic Transfer
Switch). Along with the development of technology that is all practical and online,
in research and design of an Android-Based ATS Monitoring and Control System
by utilizing the Internet Of Things (IoT) system, it allows electricity sources and
electricity quantities to be monitored and controlled by an ATS system remotely
via the Internet. In the process solar cel,scc,battery,watt meter and inverter. The
results of the drying experiment with directions that the direction of the solar cell
with the highest solar charger chontroller and watt meter measurements in the
north direction with an experiment of 5 trials in each different direction of the
solar cell and the results of the experimental test got 88% success out of nine
trials.
