Specifications

System function
Ø   6-grade power search
    In overcast weather, the solar battery’s output current is extremely tiny, then inverter will automatic open 6-grade power search function.
1.          The program can automatically open power adjustment for 6 times.
2.          The current direction can adjust from the maximum to the minimum.
3.          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 6 times, then locked in the maximum power, the ST lamp long bright.
4.          It need 10 minutes for 6-grade power search.
Ø   Wide voltage input(22-60VDC)
Achieve wide voltage input.
1.          DC voltage input: 22-60VDC
2.          Second level power variable voltage conversion
Ø   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.
Ø   Kinds of frequency output function.
1.          It can apply to 50Hz and 60Hz frequency of AC.
2.          Frequency range: 48Hz ~ 63Hz
Ø   directly connected to the solar panels (do not need to connect the battery)
Using precise Dynamic differential pressure type MPPT function, APL functions, the inverter automatically adjust the solar panels of maximum output power, simply connect the solar panel to the grid inverters. Do not need to connect the battery.
1.          Differential pressure type MPPT: 0.1 V accuracy
2.          Power lock: 10W (AC output)
Ø   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
3.          AC switching: 50Hz / 60Hz
Ø   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
