The FI-402 is designed for use in light commercial and heavy residential applications. It delivers a substantial 4kW of continuous pure sine wave power.

This FI-402 inverter is engineered for environments where multiple appliances run simultaneously, such as small restaurants, retail shops, or large family homes. Its most notable feature is the 12kW surge power, which provides the necessary torque to start heavy machinery, such as large air compressors or industrial pumps, without hesitation.

The toroidal transformer design ensures that the FI-402 operates with high thermal stability, capable of sustaining full load for longer periods compared to high-frequency counterparts. This makes it ideal for regions with frequent power cuts where the inverter serves as the primary power source for hours at a time.

The automatic voltage regulation ensures a consistent output of 220VAC ±3%, safeguarding sensitive POS systems and refrigeration units against the potential damage caused by brownouts. The product's transfer time of ≤4ms ensures seamless switching between grid and battery power, thus guaranteeing the continued smooth running of critical business operations. The wide input voltage acceptance range minimises the need for external stabilisers, reducing overall system costs.

Its pure sine wave output is compatible with all AC loads, thereby eliminating the risk of overheating in transformers and motors. The unit's design facilitates straightforward maintenance, with readily accessible fuses and clear status indicators. This inverter is the perfect solution for business owners who require uninterrupted power supply. Its reliability and high power density ensure that commerce can continue uninterrupted. It represents a professional-grade solution that balances high performance with the durability required for demanding commercial environments.
