System Function



Wide voltage input(15-60VDC

Achieve wide voltage input.

1、DC voltage input：15-60VDC

2、Second level power variable voltage conversion



High-frequency two-way and one-way grid function

1、 High frequency direct modulation, AC half wave synthesis

2、 Two-way grid means: Load consume directly. And can reverse AC current transmission.

3、 One-way grid means: Load consume directly. And banned reverse AC current transmission.



Kinds of frequency output function.

It can apply to 50Hz and 60Hz frequency of AC.

Frequency range: 45Hz ~ 63Hz



AC 0 angle with high precision auto-detection

AC phase angle of 0 through isolation amplifier then input to the MCU for high-precision detection and analysis.

The phase shift rate is less than 1%, thus achieve high-precision with phase modulation AC output together.

1、 AC phase shift: < 1%

2、 Over-zero protection: 0.2 VAC

Synchronous High-frequency Modulation

In the process of the grid, usually adapt the same phase angle in parallel. (ie, When the two-phase alternating

current total is equal to 0.Use switch to combination the two AC fusion) and the product is rectified AC

half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and

semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.

1、 Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz)

2、 Synthetic way: MOSFET full-bridge

3、 High frequency: 50KHz

Pure Sine Wave Output

Use SPWM directly to make pure sine wave output.

1、Output waveform: Adopt complementary PWM to push-pull pure sine wave.

2、Generate means: enhancement-mode SPWM



Automatic Sensing Function Solar Luminosity

Use the latest luminosity perception operation technology. The different illuminate angle and intensity of the

solar panel will produce different current output. Use advanced CPU to operate the different illuminance and the

data can be directly displayed on the LCD. Then you can visually see the sense of the strength of the sun unit.

Used more convenient.

1、 Luminosity sampling point ：power sampling point

2、 High precision AD sampling: integral AD sampling method

Power Automatically Locked (APL)

In different current fluctuations, we should use the MPPT function. When the MPPT function adjusted to the

maximum power point, the product automatically powers locked in maximum power point, then made the

output power more stable.

1、Power lock: The biggest sampling point of MPPT.

Automatically Adapt To Different Load Power Factor

Adapt to any of the power load.



Constant Current, Constant Power

This product is constant current, constant output power, without any overload, over-current phenomenon.
