The FI-302 represents a significant advance in performance, with a 3kW continuous rating that makes it a highly versatile solution for medium-sized off-grid homes and small commercial setups.

This FI-302 pure sine wave inverter is designed to efficiently handle mixed loads, from resistive heaters to inductive motors, thanks to its 9kW surge capability.

The use of a premium toroidal transformer ensures electrical isolation and significantly reduces electromagnetic interference (EMI), making it safe for use near sensitive communication equipment or audio systems. It is an excellent candidate for rural clinics or schools where power stability is paramount. The wide AC input range (165-275VAC) allows it to accept power from unstable diesel generators or weak grid connections without shutting down, acting as a powerful voltage stabiliser.

In battery mode, the output remains a pure sine wave with tight regulation, ensuring motors run cooler and quieter. The fast transfer speed of under 4ms is crucial for maintaining the operation of server racks or security systems. Efficiency is maximised at ≥85%, reducing the drain on battery banks during extended outages. The unit's design prioritises safety, featuring comprehensive protection circuits against overload, short circuit and over-temperature conditions. Its rugged construction ensures that it can withstand the vibrations often found in mobile or industrial environments.

This model is ideal for system integrators designing reliable microgrids, as it offers the scalability required to support essential infrastructure. It bridges the gap between small residential units and larger industrial systems, providing a cost-effective solution for users who need reliable 3kW power without compromising on wave quality or build standards.
