The FT-402 is a premium 4000W pure sine wave inverter designed to provide reliable, high quality AC power for off-grid and backup power applications. With its robust 4kW capacity, the FT-402 provides enough power to support a wide range of domestic and industrial devices, including sensitive electronics such as medical equipment, computers and appliances. Its pure sine wave output ensures that the AC signal is clean and stable - replicating utility grade electricity - providing superior compatibility and performance for all connected devices.

A key feature of the FT-402 is its ability to regulate AC voltage in battery (DC) mode. It maintains output at a constant 220VAC ±3%, ensuring smooth and stable power delivery even during battery operation. This level of precision helps protect equipment from voltage fluctuations that can cause performance problems or damage. Whether you're powering high-end electronics or standard appliances, the FT-402 will keep your equipment safe and running efficiently.

The FT-402 also supports single-phase 220VAC output, making it ideal for residential systems and regions where single-phase 220V is the standard. This compatibility ensures widespread use, especially in areas of Europe, Asia, Africa and parts of South America where single-phase 220V is the norm.

Designed with safety and reliability in mind, the inverter is protected against overload, short circuit, high temperature and input over/under voltage conditions. These safeguards provide peace of mind and help to extend the life of both the inverter and the equipment connected to it. With its combination of high power capacity, stable voltage regulation and pure sine wave technology, the FT-402 is the ideal solution for solar power systems, off-grid cabins, emergency backup power and mobile applications.
