Description Keep your RV, cabin, van, or off-grid system powered without interruption. The Renogy 120V 30A Automatic Transfer Switch automatically detects the primary power source (shore power, grid, or inverter) and seamlessly switches to your backup source (generator or inverter) when needed—then switches back when primary power returns. Rated for 30A / 120V AC (up to 3,600W), it delivers reliable power management for typical RV, cabin, and off-grid loads while protecting connected equipment. Manual Key Features Automatic Power Switching – Detects loss of primary power and transfers the load to the backup source without manual intervention, then prioritizes the primary source when it is restored. Durable & Heat-Resistant Build – Robust ABS housing and solid construction designed for reliable long-term use in demanding RV, marine, and off-grid environments. Easy Installation – Compact form factor (approx. 8 × 8 × 3 in) with multiple knockout holes and straightforward mounting for panel or bay installation. Built-In Time Delay – 20–30 second delay when switching to generator/inverter power allows voltage to stabilize, protecting equipment from surges and preventing rapid cycling. Versatile Applications – Ideal for RVs, travel trailers, vans, cabins, tiny homes, and backup systems; works with shore power, generators, and inverters.
