■ Using CPU control, the circuit is simple and reliable;
■ Using SPWM pulse width modulation technology, the input is a pure sine wave with stable frequency and voltage regulation, filtering out noise and low distortion;
■ Built-in bypass switch, fast switching between mains and inverter;
■ Main power supply type and battery main supply type:
A) Mains power supply type: when there is mains power, it is in the mains output, and automatically switches to the inverter output when the mains input fails;
