Singlephase Automatic Transfer Switching Controller (2P) Smart ATS changeover controller for solar inverter and generator systems, available in 16A, 20A, 32A, 40A, and 63A ratings. Why this product matters Provides automatic, reliable transfer between a solar inverter and a backup generator so power is maintained without manual intervention. Available in multiple current ratings to match household and small commercial loads, reducing the risk of overload. Twopole switching isolates both conductors during changeover, helping to prevent backfeed between power sources. Key benefits Continuous power: automatic switching minimizes downtime during utility interruptions or when the inverter stops supplying power. Versatile compatibility: designed for singlephase systems and suitable for integration with most solar inverters and singlephase generators. Rightsized for the application: choose from 16A, 20A, 32A, 40A, or 63A to fit specific circuit loads and installation requirements. Spaceefficient and robust: compact footprint and durable construction make installation straightforward in distribution panels or enclosures. Simple system integration: clear function as an ATS changeover controller simplifies wiring and operation in standard residential and light commercial setups. Main functions and attributes Function: automatic transfer switching controller that detects loss or restoration of inverter output and switches to or from generator supply as required. Poles: 2P configuration for singlephase installations, switching both live and neutral conductors. Ratings: available in multiple current capacities: 16A, 20A, 32A, 40A, 63A. Compatibility: intended for use with singlephase solar inverter systems and singlephase generator sets. Performance: designed for dependable, repeatable changeover operations to maintain continuity of service for connected loads. Typical applications Residential backup power: automatic changeover between rooftop solar inverter and portable or standby generator to keep essential circuits powered during grid outages. Small business or workshop: maintain power to lighting and essential tools by automatically switching to generator supply when inverter output is insufficient. Remote or offgrid sites: seamless transfer between inverter and generator in cabins, telecom shelters, or field installations where continuous power is required. What installers and users should know Select the current rating that matches the connected load and local wiring practices. Intended for singlephase systems; verify inverter and generator compatibility before installation. Designed for integration into standard electrical distribution setups to provide automatic and reliable ATS functionality. This singlephase, 2P automatic transfer switching controller offers a practical, scalable solution for automatic changeover between solar inverter and generator power sources, with multiple current ratings to fit a range of residential and light commercial needs.
