High quality DC to AC pure sine wave. (Note: the EU power connections are white!)

The main control chip ensures high speed and stable MCU, intelligent control, real-time monitoring, AC output frequency is more accurate, and the operation is more stable.

With bipolar SPWM drive, the sinusoidal waveform is more accurate and the inductive load capacity is stronger.

Multiple protection functions: input low voltage shutdown protection, input high voltage shutdown protection, battery high and low voltage alarm, overload protection, short circuit protection, overheating protection.

Safety isolation: input and output isolation.

UPS / Battery Charger function: UPS means uninterruptible power supply, providing a stable, uninterrupted power to the load. When the mains power is normal, the UPS supplies power to the load and also charges the battery. When the mains power is interrupted, the UPS immediately switches to battery power and continues supplying 220V AC power to the load to ensure it operates normally.
