The automatic control is ussually called Automatic Transfer Switch (ATS). The ATS function is simply to transfer the power to the load automatically from a primary source (Solar Power Plant) to the backup source. Informing an ATS panel data collecting is needed, for istance, spesification of each components, the time of the transfer interval between backup and supply by observing directly when the tool will be designed and tested when the tool is finished in the design. The designed ATS is used for R1- TR 2200 VA customer load including 16 pieces solar panel of 100 WP, 10 pieces of battery with 12V system voltage and capacity 200 AH, inverter 2000 Watt, MCB with 10A curent rating, and Omron MKS2P 8 pin relay. After finishing the panel design, the power switching does not occur flicker, the power switching takes 0,045 second, the power circuit is differentiated between PLTS and PLN to get the reliable switching supply. Design of ATS with IoT Microcontroller will get fast switching and with minimum failures.} }
