Micro Inverter WVC300
System Function
• Power line carrier-current communication
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. 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: 9600PS(Can customize according to customers request);
5. Modulation mode : FSK+DSSS;
6.Newsletter distance:400m;
• 6-grade power search---In overcast weather, the PV Panel" s output current is extremely tiny, then inverter will automatic open 6-grade power search function, and keep outputing efficent and steady during the low power.
• Wide voltage input(22-50VDC)---
1.DC voltage input:22~50VDC; 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.
• Kinds of frequency output function--1.It can apply to 50Hz and 60Hz frequency of AC; .Frequency range: 45Hz ~ 64Hz;
•Directly connected to the solar panels (do not need to connect the battery)
• AC 0 angle with high precision auto-detection-=-High-precision analysing the AC phase angle .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.
• Synchronous 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.
• Power Automatically Locked (APL)--- automatically powers locked in maximum power point, made output more stable.
• Constant Current, Constant Power---constant current and output power, without any overload, over-current phenomenon.
• Exactly and timely automatic Island Effect Protection
• High-Frequency High Conversion Rate---Adapt high frequency converter, the output more efficient.
• Maximum Power Point Tracking (MPPT)---high-precision (MPPT) operation power, automatic and immediate adjust the solar panels output power at the maximum output point, made the inverter discharge to power grid with the highest efficiency.
