SRNE SR-IBC12-3kW Pure Sine Wave Inverter

SRNE SR-IBC12-3kW Pure Sine Wave Inverter

The SRNE SR-IBC12-3kW is a unidirectional (one-way) pure sine wave inverter with built-in transfer (bypass) switch functionality.

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
