l High-frequency
two-way and one-way grid function
1〠High frequency direct modulation, AC
half wave synthesis
2〠Two-way grid means: Load consume
directly. And can reverse AC current transmission.
3〠One-way grid means: Load consume
directly. And banned reverse AC current transmission.
l Kinds
of frequency output function.
It can apply to *0Hz and *0Hz frequency of AC.
Frequency range: *5Hz ~ *3Hz
l directly
connected to the solar panels (do not need to connect the
battery)
Using precise Dynamic differential
pressure type 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.
1〠Differential pressure type MPPT: 0.1 V

2〠Power lock: 5W (AC output)
l AC
0 angle with high precision auto-detection
AC phase
angle of 0 through isolation amplifier then 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.
1〠AC phase shift: <
1%
2〠Over-zero protection: 0.2
VAC
3.AC
switching: *0Hz / *0Hz(automatic detection,
automatic switching)
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 **0Hz first, then the machine use the high frequency
current in the circuit and semi***0Hz frequency alternating
current generated combination, to achieve high-frequency
modulation.
1〠Modulation synthesis: half wave
and full-bridge modulation synthesis (**0Hz /
**0Hz)
2〠Synthetic way: MOSFET
full-bridge
3〠High frequency:
*0KHz
Pure Sine Wave Output
Use SPWM directly to make pure sine wave output.
1ã€Output waveform: Adopt complementary PWM to
push-pull pure sine wave.
2ã€Generate means:
enhancement-mode SPWM
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.
1〠Luminosity sampling
point：power
sampling point
2〠High precision AD sampling:
integral AD sampling method
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.
1ã€Power
lock: The biggest sampling point of MPPT.
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.
Current Limit Protection
Current limit
l Stack
Multiple Machines
l 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.
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. MPPT is for
short of " Maximum Power Point Tracking". It means the controller
can sense the voltage of the solar panels on time, and can track
the highest voltage and current (VI).Then made the inverter
discharge to power grid with the highest
efficiency.
