2017 New Solar PV On Grid Inverter DC22-50V to AC110V/220V 300W Solar Grid Tie Micro Inverter with Communication Function

 

System Function

Power line carrier-current communication(this is optional function)

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-gradepowersearch

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;

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 PowerPoint 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 300W stacking can achieve 1200W.  the number of the stacking is unlimited.

 

DC input

Input voltage range: 22V to 50V, recommend using the power more than 600W 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.

Installation of Micro Inverter

Step 1. Installation for fixed the inverter on the PV holder with the screws attached is as following:

Step 2.  Connect the two DC terminal of the PV to the inverter, positive to positive, negative to negative. Show below:

 

Step 3. Open the waterproof cap on AC output side of the micro  inverter, then plug  to AC power  line. Show below:

Step 4. Plug the AC output line to main AC cable;

 

Step 5. Repeat the fir st step to the third step to complete the installation of micro  inverters; 

 

Step 6. Finally, please connect the AC main cable to the utility grid   to run renewable energy  and saving $$$!
