It seamlessly shifts between grid and solar power\u2014or solar and inverter\u2014without manual intervention, protecting your equipment and simplifying installation. TOSUNlux solar PV ATS units provide essential safety features, precise control, and durable construction. With options for single-phase and three-phase applications, they serve as the reliable core of any integrated power system. Hero Product Highlight EP Changeover Switch Reliable and compact, TOSUNlux EP Changeover Switch enables smooth power source transition, ideal for backup systems and industrial panels. View Product Why You Need an Automatic Changeover Switch Connecting solar or inverter output directly into your main panel isn\u2019t safe. Without proper isolation, you risk backfeeding the grid, damaging equipment, or endangering utility workers.&nbsp; A proper ac dc automatic changeover switch ensures only one power source is active at a time, making transitions safe and compliant. How It Works with Solar and Inverters A changeover switch monitors two sources\u2014for example, solar inverter and main grid. When solar power is sufficient, it directs energy from the inverter to your loads.&nbsp; As panels lose output (like at dusk), the switch detects the drop and flips to grid power within milliseconds. If you have batteries connected, it can switch between solar\/battery and grid based on your settings. This automation takes the guesswork out of hybrid systems and prevents damage or interruption during switchover.
