High efficiency indoor design 500w Solar Micro Grid Tie Inverter Input 10.5-28V DC for Small solar Power System  

 

 

directly connected to the solar panels (do not need to connect the battery)

Using precise 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.

 

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.


Synchronous High-frequency Modulation

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.


Pure Sine Wave Output
Use SPWM directly to make pure sine wave output.

 

Automatic Sensing Function Solar Luminosity

Use the latest luminosity perception operation technology. The different illuminate angle and intensity of the solar panel will produce different current output. Use advanced CPU to operate the different illuminance and the data can be directly displayed on the LCD. Then you can visually see the sense of the strength of the sun unit. Used more convenient.

 

Power Automatically Locked (APL)
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.


Maximum Power Point Tracking (MPPT)
Because the current intensity and the voltage changes at any time, if there is no power point tracking, there will be a lot of problems. In the past time, usually adopt a solar controller, but this product uses high-precision MPPT operation power, automatic and immediate adjust the solar panels output power at the  maximum output point, then achieve a stable output purposes.


Automatically Adapt To Different Load Power Factor
Adapt to any of the power load.

Constant Current, Constant Power

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

 

Automatically Shut Down When The Power Output Of a Fault

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


Current Limit Protection
Current limit

 

Stack Multiple Machines

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

 

High-Frequency High Conversion Rate

Adapt high frequency converter, the output more efficient.

System Block Dragram & Application

 

 

Input and output
(1) DC input limit

 

Input voltage range: 10.5V to 28V

Solar Panel: Recommend using the standard voltage  of 17.5V PV panels or 24V Battery.
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.
Wind turbine system: Rated voltage 24VDC, maximum voltage 28VDC.


(2) AC output:

Voltage range of the inverter whose output is 220V AC.: 170V - 260V

Voltage range of the inverter whose output is 110V AV.: 90V - 160V

 

5 LED Indicator:

(1) Red LED:
1,Low-voltage protection (input DC voltage is less than 10.5VDC).
2,Over-voltage protection (Input DC voltage is greater than 28.5VDC).
3,Over-temperature protection (when the chassis temperature is above 75°C,
the temperature dropped about 2-10 minutes to restart automatically after cooling).
4,Fault Protection (when 110VAC or 220VAC power outage or shutdown).
5,Islanding protection: When the electric supply stop, the inverter automatically shut down output.

 

(2) Green LED:
1,Green LED flashing: The inverter is adjusting power output. MPPT is in working condition.
2,Green LED long in time: The inverter is in working condition with the maximum output power.


Notes  

                

---Please pay attention of the voltage when use the product. The voltage is from 10.5—28V, if is not these voltage the product may broken.
