Renogy 30A Automatic Transfer Switch for 12V 1000W / 2000W / 3000W Pure Sine Wave Inverter

Easily switch between two independent 120V AC power sources—such as shore power, inverters, or generators—without manually plugging or unplugging cables. This automatic transfer switch prevents both sources from running simultaneously, protecting your RV’s electrical system from potential damage.

• 【Automatic Transfer Switch Designed for 12V Inverter Systems】 This product is an automatic power transfer device specifically engineered for 12V inverter systems. It seamlessly switches to inverter output powered by a 12V battery when the main AC power (e.g., grid or generator) fails, and automatically returns once main power is restored—all without manual intervention, ensuring uninterrupted power supply. Please note: Your inverter must feature an AC input port to safely integrate with this system.
• 【Compatible Only with 12V Inverters Featuring AC Input】 Fully compatible with major 12V pure sine wave inverters from brands such as Renogy, Victron, and BELTTT (supporting models ranging from 1000W to 3000W). A mandatory requirement is that the inverter must include an AC input function. Ideal for RVs, solar off-grid systems, and home backup power setups where safe connection between inverter, grid power, and generator is essential.
• 【Durable Construction for Enhanced Inverter System Reliability】 Constructed with high-quality heat-resistant and corrosion-proof ABS material, ensuring consistent performance even in demanding conditions. Built-in surge protection and voltage fluctuation management help safeguard your inverter and connected devices against potential damage.
• 【Easy Installation with Clear Inverter Wiring Labels】 Features user-friendly terminals with clear markings for inverter, battery bank, and AC input connections, simplifying setup. Includes pre-punched knockouts for neat cable management. Designed for dry, well-ventilated areas; outdoor installation requires a waterproof enclosure.
• 【Smart Delay Protection for Your Inverter and Loads】 Equipped with a 20–30 second transfer delay when switching to inverter or generator power. This allows ample time for the inverter to start up and stabilize output voltage, preventing inrush current and ensuring safe operation for both the inverter and connected sensitive electronics.
