Description

Powerful, scalable off-grid energy management

The IVEM12048-II is a high-performance 12kW, 48V off-grid solar inverter designed to provide reliable power for large residential, commercial and backup-energy installations. It delivers pure sine-wave output for stable operation of connected electrical equipment.

Its built-in MPPT solar charge controller supports two solar-input strings, with up to 15kW of total PV input power. Integrated Wi-Fi enables convenient system monitoring through the Fsolar mobile app.

The inverter supports mains or generator power and can operate without a battery for greater system flexibility. Configurable voltage, charging-current and charging-mode settings allow the system to be adapted to different energy requirements.

For larger installations, up to six compatible units can be connected in parallel when a battery is connected. Automatic restart, cold-start functionality and built-in protection help ensure dependable operation.
