2. Display function
A. AC voltage display
B. Outage display
C. Power shows
D. AC frequency display
E. DC over-voltage display
F. DC under- voltage display
G. Power adjust display

3. 12-grade power search
A. The program can automatically open power adjustment for 12 times.
B. The current direction can adjust from the maximum to the minimum.
C. In automatic adjustment process, we will see the low light flashing. And the power will keep as a starting point, from 0 to the maximum output power, and it will restart at most for 12 times, then locked in the maximum power, the st lamp long bright.
D. It need 10 minutes for 12-grade power search.
4. Wide voltage input(15-60vdc)
A. DC voltage input: 15-60vdc
B. Second level power variable voltage conversion
5. High-frequency two-way and one-way grid function
A. High frequency direct modulation, AC half wave synthesis
B. Two-way grid means: Load consume directly. And can reverse AC current transmission.
C. One-way grid means: Load consume directly. And banned reverse AC current transmission.

6. Kinds of frequency output function.
It can apply to 50Hz and 60Hz frequency of AC.
Frequency range: 45Hz ~ 63Hz
7. Directly connected to the solar panels (do not need to connect the battery)
A. Differential pressure type MPPT: 0.1 v accuracy
B. Power lock: 10W (AC output)
8. AC 0 angle with high precision auto-detection
A. AC phase shift: < 1%
B. Over-zero protection: 0.2 vac
C. AC switching: 50Hz / 60Hz

Synchronous high-frequency modulation
A. Modulation synthesis: Half wave and full-bridge modulation synthesis (100Hz / 120Hz)
B. Synthetic way: Mosfet full-bridge
C. High frequency: 50kHz
Pure sine wave output
A. Output waveform: Adopt complementary PWM to push-pull pure sine wave.
B. Generate means: Enhancement-mode spwm
9. Automatic sensing function solar luminosity
A. Luminosity sampling point: Power sampling point
B. 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.
A. Power lock: The biggest sampling point of MPPT.
Automatically adapt to different load power factor
Adapt to any of the power load.

10. Constant current, constant power
This product is constant current, constant output power, without any overload, over-current phenomenon.
11. Automatically shut down when the power output of a fault.
Current limit protection
12. Stack multiple machines
13. Multiple small power inverters in parallel can achieve large output power.
14. High-frequency high conversion rate
Adapt high frequency converter, the output more efficient.

15. Maximum power point tracking (MPPT)
Because the current intensity and the voltage changes at any time, if there is no power point tracking, there will be a lot of problems. In the past time, usually adopt a solar controller, but this product uses high-precision MPPT operation power, automatic and immediate adjust the solar panels output power at the maximum output point, then achieve a stable output purposes.
