Switching Power is supplied by the independent system

AC mains priority.

Always use AC mains as priority input to provide AC output and automatically charge the battery, only

The full bridge rectifier and manboard structure are highly optimized.Input and output circuits are isolated.

4kw off grid inverter

The reason why the sine wave inverter can output a complete sine wave is because it adopts SPWM technology, which is more advanced than PWM technology.

The principle of SPWM is based on the equivalent principle that pulses act on time function devices: if pulses act on time function devices, the product of the peak value and the action time is equal, and these pulses can be approximated as equivalent.

Low working noise and high conversion efficiency

Adopt foreign high frequency inverter technology. The control circuit is simple and reliable, and quickly responds to changes in the external environment

Filter out noise and pure sine wave with low distortion

Strong load capacity, good load compatibility, internal overload, overvoltage, undervoltage, short circuit, high temperature, reverse connection and other alarm protections improve the reliability of the inverter and the continuity of power supply

Equipped with input DC voltage on-line and off-line protection, which can protect the battery and increase the service life of the battery

High electric density, small size and light weight

5000 watt pure sine wave inverter
