Solar Energy Electric 4400 Va, 3x220 Volts, 50 Hertzs with Sliver Cells and Changeover Switch Based PLC Festo FC-34
This paper present about solar energy electric with the capacity 4400voltampere, 3x220volts, 50hertzs. This capacity is assumed enough for many household, home industry, polyclinic, offices. In this case that solar panel is used “sliver cells” type because, use less silicon, more efficient, flexible, transparent, bifacial, thin. This system is build with charge controller utility to battery bank and from battery bank to 3-phase inverter. The 3-phase inverter is useful to convert direct current to 3-phase alternating current voltage. 3phase inverter used is consist of six unit of IGBT components. The output of 3-phase inverter is connected to input 3-phase stabilizer, and the output of 3-phase stabilizer is to lead to the loads. The output voltage of 3-phase stabilizer is detected and to be input to PLC (Programmable Logic Controller) Festo FC-34, because PLC to control change over-switch that the function as actuator with 5 seconds setting time, is the load supplied by solar energy electric, electric from PGL (Public Grid Line) or the electric from generator set. The alternative is ordered according with sequence of operation cost. The result of research, the output voltage from stabilizer 218.5volts, the input voltage of charge controller 56.16volts, the input voltage of inverter 48.0volts, the output voltage of inverter 205.6volts, electric current to the load 9.5amperes. If the output voltage of stabilizer less than or equal 190volts, so the PLC will actuate change over switch as the actuator to active to PGL power or to generator set power. It is found that overall system works effectively.
