1000W DC TO AC 24v to 220v off grid pure sine wave power solar inverter with FCC certification

Model :?LI-10224

?

DSP smart chip Core: An individual 64-bit DSP control chip, more text samples and control functions

The detection and control program is written into the DSP chip. The results are fetched by DSP chip and the inverter is controlled by DSP chip. The advantage is that the value is accurate(by effective value). Tolerance is less than 0.01%

?

B. Most of inverters in the market are controlled by hardware circuit.



Disadvantages:

1.Components will have the ageing problems.

2.Complicated production processes, full of wires, which will raise not only the manual defects during production and after sales problem.

?

Photoelectricity isolation circuitry technology:

Top One: It can detect and modulate the pulse width of boost circuit, reduce the EFT(Electric Fast Transient) and raise anti-interference.

Other: The inverter without this function. Which will cause high EFT(Electric Fast Transient) and low anti-interference.
