System function

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 luminance 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, and 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.
