The FT-402 pure sine wave inverter is designed for use in luxury villas and small off-grid commercial power stations. It features a reinforced low-frequency toroidal transformer core that can withstand the simultaneous start-up of multiple high-power household appliances.

The FT-402 provides a steady supply of pure sine wave alternating current and can handle a peak surge of up to 12 kW. This means that you can use your air conditioner, washing machine and other big kitchen appliances at the same time without causing any problems with the power supply. The FT-402 makes it easier to match batteries to dual 24 V and 48 V high-voltage systems. It is compatible with large-capacity LiFePO4 lithium battery packs, as well as all industrial lead-acid storage batteries.

It has an intelligent charging logic that limits the DC charging voltage to make the battery last longer. The inverter needs an external, standalone maximum power point tracking (MPPT) solar charge controller to capture solar energy, because the FT series has a split photovoltaic design. This means that users can increase the power of their PV array without having to replace the main inverter unit. This in turn reduces the costs of upgrading the system in the long term. The 35 A AC mains charger can be adjusted to provide extra power for charging when sunlight is not strong. The built-in AVR voltage stabiliser keeps the battery-mode output voltage to within plus or minus 3%, protecting precision electronic equipment.

The ultra-fast transfer switch (<=4 ms) makes sure there's no risk of blackouts for important commercial equipment by quickly switching power between the grid, generator and battery storage. There are five clever ways to use this machine, which cover all situations where you need to manage energy. One of these ways is an automatic mode that you don't need to watch, which reduces the cost of daily maintenance. RS485 communication ports allow interaction with the lithium battery BMS in real-time, and an optional Wi-Fi module enables remote monitoring via the cloud, as well as parameter modification and push notifications for faults via mobile applications.
