Specification:

System Function:

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

MPPT using precise function, APL functions, solar panels automatically adjust to maximum output power, simply connect directly to the solar panel 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 and input to the MCU for high-precision detection and analysis, the phase shift rate of only <1%, thus achieving high-precision AC and combining with the phase modulated output.

Ynchronous High-frequency Modulation

In the course of the grid, usually with the same phase angle and the net (ie, two-phase alternating current total is equal to 0, with the switch to the two AC fusion) and the product is first rectified AC half-frequency AC to 100Hz, Then the machine produces high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.

Pure Sine Wave Output

SPWM directly with pure sine wave output.

Automatic Sensing Function Solar Luminosity

Brightness perception latest computing technology, solar radiation in the solar panel angle for different light intensities produce different current output, using advanced CPU computing the light of their different degrees, can be directly displayed on the LCD , you can visually see the sense of the strength of the sun unit, use more terms.

Power Automatically Locked (APL)

The current strength of the different 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, the output power is more stable.

Maximum Power Point Tracking (MPPT) 

Current intensity, voltage constantly changes, if there is no power point tracking, then there will be a lot of problems in the past usually adopted a solar controller, this product uses high-precision MPPT computing power, automatic and immediate to solar panels output power adjustment in the maximum output point, in order to achieve a stable output purposes

Automatically Adapt To Different Load Power Factor 

Adapted 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 planning power outage there is a failure, the inverter will automatically turn off the output.

Current Limit Protection 

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

Stack Multiple Machines (in the parallel machine used) 

Multiple machines in parallel can be used to achieve a small power inverter in parallel for the power output.

High-Frequency High Conversion Rate 

High frequency converter, the output more efficient.

User Guide:

1. Installation Connection

(1). Red terminal: Connect DC positive, black terminal: Connect DC negative. Shown in Figure 1.

Figure 1 

(2). AC socket: Connection to the mains. The AC cord to the inverter 3 foot outlet, then the AC cord to home 3PIN AC outlet. Are shown in Figure 2, Figure3.

Figure 2

3. Stack using

In order to achieve higher power use requirements, the use of this product can be stacked, such as: 4 grid inverter 1000W of stack used is equal to 4000W, and the number of open stacks.

4. Input and output

1. DC input limit

      Input voltage range: 10.5V to 28V

      Solar Panel: recommend the use of power greater than 30W, the standard voltage17.5V PV panels.

      Recommended, and even solar panels, thread will result in high input voltage inverter which exceeds the working voltage range.

     Wind turbine: Rated voltage 24VDC, maximum voltage 28VDC.

2. AC output: 

     Output 220V AC power inverter can be used in voltage: 170V - 260V, 50 Hz

     Output 110V AC power inverter can be used in voltage range: 90V - 160V, 60 Hz

5. LED Indicator

1. Red LED: 

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

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

    3. Over-temperature protection (when the chassis temperature is above 75, 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: electricity disconnected, the inverter automatically shut down output.
