1000w-6000w Dc To Ac Solar Inverter

FI series 1000w-6000w dc to ac solar inverter

    When the input AC voltage of the parameter regulator is 150V-260V, the output voltage regulation is better at 220V. Below and above this range, its efficiency drops. The single-chip microcomputer is used for the first step control, so that the input voltage below 310V and above 90V can be adjusted and controlled in the range of 190V-250V, and then the parameter voltage regulator is used for voltage regulation.

    The AC voltage input from the mains fluctuates greatly, and after the interference voltage such as high-frequency pulses is filtered out by the overvoltage absorption filter circuit, it is sent to the DC switching regulated power supply, the AC sampling circuit and the control execution circuit.

    The power of the DC switching regulated power supply is small, but it can change the AC voltage of 60-320V into +5V, +12V, -12V DC voltage. The +5V voltage is supplied to the single-chip microcomputer, and the ±12V voltage is supplied to the high-power switch module of the control circuit.

    The single-chip microcomputer analyzes and judges the input voltage data collected by the sampling circuit and sends a control signal to the trigger circuit to control and adjust the output voltage.

    The control execution circuit is composed of SSR zero-crossing switch high-power module and tapped autotransformer. An RC absorption circuit is used between the SSRs to absorb overvoltage and overcurrent, so that the SSR will not be damaged when switching. The control execution circuit controls the input voltage of 90-310V in the range of 190V-240V, and then sends it to the parameter regulator for precise voltage regulation.
