The CORE 12V 2000W Pure Sine Wave Inverter with Transfer Switch is a reliable and powerful DC-to-AC power solution designed for off-grid systems, caravans, trailers, camper vans, cabins, and backup power applications. Delivering clean and stable pure sine wave power, it safely operates sensitive electronics and household appliances without interference.
With its built-in automatic transfer switch and grid priority function, the inverter seamlessly switches between battery power and utility AC power, ensuring uninterrupted operation when mains power is lost.
Unlike modified sine wave inverters, this pure sine wave inverter delivers cleaner, smoother, and more reliable electricity, making it ideal for powering:
The integrated transfer switch automatically changes between battery power and AC mains supply within milliseconds, ensuring continuous power availability.
The grid priority function ensures utility AC power is used first whenever available, automatically switching to battery power during outages.
Built-in electronic protection systems help protect the inverter, batteries, and connected devices against:
