GTI-800 On Grid Inverter

  System Function                                             

l  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 powersimply connect the solar panel to the grid inverters. Do not need to connect the battery.

l  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.

l  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.

l  Pure Sine Wave Output

Use SPWM directly to make pure sine wave output.

l  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.

l  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.

l  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.

l  Automatically Adapt To Different Load Power Factor

Adapt to any of the power load.

l  Constant Current, Constant Power

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

l  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.

l   Current Limit Protection

    Current limit

l  Stack Multiple Machines

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

l  High-Frequency High Conversion Rate

Adapt high frequency converter, the output more efficient.

Installation instruction                                                  


1Please read the below notes carefully before installation.

 A) Make sure the open voltage and operation voltage is in the range of 10.5-28V, and we recommend the 18V rated voltage solar panel or 24V battery.

 B) Make sure the inverter’s AC voltage and frequency is the same with power grid voltage and frequency.

 C) Installation inverter in the low humidity and well-ventilated place to avoid the inverter damp and overheating, And clear the inflammable and explosive materials around.

 D) Recommended to use 4AWG DC input cable that can handle more than 50A current.

 E) DC input cable no more than 8M, because long DC cable will reduce the voltage from solar panel     to inverter, then make some loss.

 F) There must be a circuit breaker between solar power generation and power grid(show like the  “ switch  A” in figure 1). And there will be no load before the circuit breaker.

 G) Before connect all the connections, you must disconnect the utility power. After make sure the all    connections are right then connect the utility power.

 H) If you need to disconnect the mains switch when the solar power generation is in operation, you must disconnect the control switch first(show like the “switch  A” in figure 1).

 I)  Avoid children touch or play the inverters, in order to prevent electric shock.

 J) Non-professional do not disassemble the inverter, only qualified serviceman can repair it.

 

2Connection DC terminal

   Connect the solar panels positive terminal to inverter’s positive terminal, and negative to negative.

   And you must screw up the nut to avoid the bad contact. 

  Show in figure 2:


3、Connection of AC terminal

   Before connect the inverter’s AC cable to the socket, you must disconnect the utility power. Then put

   the AC cable which has holes terminal into the inverter’s 3 feet port and the pin terminal to the

   socket. Please make sure both of the terminal are connect fastness to avoid bad contact.    

 

   Show like figure 3: 

4Operation

   After all connection, first open the mains switch, then open the inverter. When the inverter’s green

   LED shows, it means the inverter start to work.

 

5Several or many inverters used in parallel.

   In order to achieve higher power, we can use this inverter in stack. For example: 4 pcs of 300W

   grid tie inverter used in stack can achieve 1200W. And the stacking number is unlimited.

 

   Show as figure 4: 

6Single-phase connection

  Connection electrical diagram of the solar inverter used in single-phase power generation system, show

  as below:


7 Three-phase connection

     Connection electrical diagram of the micro inverter used in three-phase generation system, show

     below:


8Trouble shooting

   1Red LED shows:

   ACheck if the input voltage to inverter is lower than 10.5V or higher than 28V.

   BCheck it the AC cable connect to utility power correct or the utility power is disconnect.

   2No LED shows:

   ACheck if the DC input voltage is in too low.

   BCheck if the DC fuse is broken. 

 

9 LED Indicator                                          

ARed LED

   1Low-voltage protection (input DC voltage is less than 10.5VDC).

   2Over-voltage protection (Input DC voltage is greater than 28.5VDC).

   3Over-temperature protection (when the chassis temperature is above 75,

       the temperature dropped about 2-10 minutes to restart automatically after cooling).

   4Fault Protection (when 110VAC or 220VAC power outage or shutdown).

   5Islanding protection: When the electric supply stop, the inverter automatically shut down output.

 

BGreen LED

   1Green LED flashing: The inverter is adjusting power output. MPPT is in working condition.

   2Green LED long in time: The inverter is in working condition with the maximum output power.
