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：400m

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.

Achieve wide voltage input.

1.DC voltage input：22-50VDC

2.Second level power variable voltage conversion

1.High frequency direct modulation, AC half wave synthesis

2.Two-way grid means: Load consume directly. And can reverse AC current transmission.

1.It can apply to 50Hz and 60Hz frequency of AC.

2.Frequency range: 48Hz ~ 63Hz

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)

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.

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

In different current fluctuations, we should use the MPPT function. When the MPPT function adjusted to the maximum power point, the product automatically powers locked in maximum power point, then made the output power more stable.

This product is constant current, constant output power, without any overload, over-current phenomenon.

When the city power system is in failure, the inverter will automatically turn off the output.

2.   Current limit

Multiple small power inverters in parallel can achieve large output power.

Adapt high frequency converter, the output more efficient.

The peak voltage (Vpp) of the solar panels is about 38V when it in factory. And the environment temperature is 25 ° C. The reason of setting this temperature(interestingly, different from the subjective imagination, we ordinary people the conclusion may let us surprised) is that when the weather is very hot, solar panels’ peak voltage will fall to about 36 V while in cold weather, the peak voltage can achieve 43 V.

Now we back to contrast the difference of MPPT solar energy grid inverter and traditional inverter. The traditional solar inverter is a bit like the manual gearbox. When the engine speed increase, while the gearbox gear don't increase at the same time, it will definitely affect the speed of the car. For traditional inverter speaking, the parameter output power is been set in factory. It likes a car have been fixed set on fixed 1 gears, no matter how powerfully you trample accelerator, the speed of a car is limited. While have the MPPT function it will be different, it is automatically. It will automatically adjust the gears according to the engine’ speed, so it can make cars in the most gears in a reasonable efficiency standard operation. It means the MPPT controller can track the maximum power point of solar panels in real-time then express the biggest efficiency of solar panels. The higher the voltage, the more power can be output through the MPPT. Thus improve the charging efficiency. Theoretically speaking, using MPPT, the efficiency can be increased by 50% compared with the traditional inverter. But due to environmental impact and various around energy loss, the ultimate efficiency can improve 20%-30% according to our actual testing.

In order to achieve higher power use requirements, this product can be stacked. Such as: 4 micro inverter of 260W stacking can achieve 1040W. And the number of the stacking is unlimited.  

Input voltage range: 22V to 50V

Solar Panel: Recommend using the power more than 30W and the standard voltage of 36V PV panels.

Recommend using multiple solar panels. Solar panel in series will result in high-input voltage which will exceed the working voltage range of the inverter.

Voltage range of the inverter whose output is 220V AC.: 190V - 260V，50HZ

Voltage range of the inverter whose output is 110V AC.: 90V - 160V，60HZ
