3KW Low Frequency Single Phase Inverter

The FI-302 is a versatile and powerful power management product designed to meet the growing demands of modern energy storage and backup systems. Designed for reliability and adaptability, the FI-302 supports both 24V and 48V battery systems, offering seamless integration into a wide range of residential, commercial and industrial power solutions.

One of the outstanding features of the FI-302 is its dual voltage compatibility. Whether your system runs on 24V or 48V, this unit automatically adapts to the voltage requirements, offering maximum flexibility and reducing the need for separate models or hardware changes. This feature is ideal for users planning to upgrade their systems or operate mixed voltage installations.

Another key highlight is its powerful AC charging capability. The FI-302 supports a maximum AC charging current of 35A, which is fully adjustable according to the specific needs of the application. This high charging capacity enables faster battery replenishment, reducing downtime and increasing system efficiency. The adjustable nature of the charge current allows precise control, ensuring safe charging practices for a wide range of battery chemistries and capacities.

The FI-302 also features intelligent operating modes designed to optimise power consumption and system performance. It offers three modes of operation:

Utility Priority Mode - This mode prioritises power input from the grid or AC source. The system first uses utility power to supply loads and charge the battery. It only automatically switches to battery power when the grid is unavailable. This mode is ideal for areas with a stable utility supply where backup power is occasionally required.

Solar Priority Mode - In this configuration, the FI-302 prioritises energy from solar panels (when integrated with an inverter or solar array) to power loads and charge the battery. This mode maximises the use of renewable energy, reducing electricity bills and carbon emissions.
