Energy instability in developing countries creates a need for automation of electric power generation or alternative energy sources to support the provision of public services. the business processes depend on the power source and if the changeover processes are manual, serious time is not only wasted, but also causes damage to the device or machine due to human errors during switching connections, which could bring massive losses. The generator is started by a relay that switches the battery voltage to the generator start coil, while the main power relay switches the load to the public supply or generator.
