ITEM Features:

◆ Power line carrier-current communication(this is optional function, please confirm the spec outside the box first .)

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 customer's 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 pen 6-grade power search function, and keep output efficient 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; 2.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.

◆ Stack using---Such as: 4 micro inverter of 260W stacking can achieve 1040W. the number of the stacking is unlimited.

◆ DC input---Input voltage range: 22V to 50V, PV Panel: Recommend using the power more than 30W and the standard voltage of 36V PV panels. Suggestion making the PV in parallel.

◆ AC output---220VAC: 180V - 262V, 50HZ; 110V AC: 80V - 160V ,60HZ.
