Specifications
1.Wide voltage input(22-60VDC)2.Kinds of frequency output function.
3.Automatic Sensing Function Solar Luminosity
System function:
Ø Power line carrier-current communication(Used in WVC series)
By using electric power as a carrier of AC alternating current, can modulate high-frequency and carrier frequency (60KHz) in AC wire transmission and can achieve the communication/ newsletter between inverters or between inverter and computer. And it can transfer the power data and the brightness date of the sunshine in the real-time. Also monitor all functions of inverter.
1. Carrier frequency:60KHZ(Frequency customizable)
2. Interface way:TTL level serial interface
3. Carrier rate:300BPS
4. Serial rate:9600BPS(Can customize according to
customer's request)
5. Modulation mode:FSK+DSSS
6. Newsletter distance:2Km
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.
