directly connected to the solar panels,Or directly connected to any applicable DC power
supply power (including battery)
MPPT using precise function, APL functions, solar panels automatically adjust to maximum output power,
simply connect directly to the solar panel grid inverters, Or directly connected to any applicable DC power
supply power (including 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.
Synchronous 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(Use battery as power supply the power supply, this function are of no
use.)
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.
