The SRNE SR-IBC12-3kW is a unidirectional (one-way) pure sine wave inverter with built-in transfer (bypass) switch functionality. It is tailored for off-grid, RV, or hybrid power systems where AC utility input and DC battery input need to be managed together. The inverter is designed to seamlessly switch between utility (grid or shore power) and inverter output, providing uninterrupted AC power to loads. Major features include: Pure sine wave AC output with low harmonic distortion Automatic bypass/utility mode (UPS-style switching) Multiple operating modes (ON, ECO, etc.) for efficiency Comprehensive protection suite (over/under voltage, overload, short circuit, over temperature) Intelligent cooling (fan + natural) Communication interfaces: Bluetooth, RS485, external switch terminals RCD (residual current device) leakage protection built in A word about SRNE - SRNE is a globally established manufacturer specialising in inverters, solar charge controllers, and energy storage solutions for both residential and mobile applications. Widely recognised as one of the world’s leading producers of solar controllers and RV power solutions, SRNE supplies technology to markets across Europe, Asia, and beyond. Make no mistake — SRNE products are engineered and manufactured to high international standards, combining proven reliability, robust build quality, and smart charging technology to deliver a dependable, high-performance energy solution you can trust.
