l         Connect
to DC Power Supply and Direct-ouput Power Grid
directly
DC power supply refer
to devices included solar panels, batteries and wind power
generators with AC/DC controller, etc. All DC power supply output
voltage fit with inverter voltage setting range which is
****0VDC.
Power grid refer to
single phase civilelectricity
grid. Such as
**0V（*****0V）and **0V（******0V）single phase civil electricity
grid.
Shengyang small power
on-grid inverters can connect to power grid directly and
uploading electric power directly because of inverter output
current wave form is pure sine wave which is same as civil
electricity grid.
There must be
electricity on power grid is first necessity of inverter
operating. When there is power outage or fault of power grid,
inverters will be not operating. And it is the biggest difference
between on-grid inverter and off-grid inverter.

l         AC
0 Angle Phase High Precision Auto-detection
MCU
process for high-precision detection and analysis after AC 0
angle phase pass through isolation amplifier and into MCU,
phase shift rate is less than 1%, and finally achieving
high-precision of cophasal modulation AC combined Output.
l         Synchronous
High-frequency Modulation
In
process for grid connectivity, usually approach with cophasal
angle for grid(ie, when total current of inverter and grid is 0,
combined current by switch). But our inverter approach for grid
with same frequency and same pahse is DC to AC first, then
rectified AC current into pulse electric which is half-frequency
**0Hz, finally combined pulse electric modulation with current of
grid and then fed into power grid.
l         Pure
Sine Wave Output
Adopting
Sinusoida PWM process for pure sine wave output which is same
wave form of grid. No interference for grid.
l         Superstrong
Shadow Resistance of Inverter
Adopting high
frequency conversion operating, less transimission loss will be.
In cloudy days or inadequate sunshine days, if only there is
3W*5W output from power supply and into inverter, inverter
can be operate AC conversion. But of cause, output is
proportional . The more power the more output power
and vice versa. Inverter can operate in such low power
supply, it’s indicate inverter power conversion operating times
can be up more than 8 hours every day, and this is an advantage
which is large power inverter can not be compared with.
l         Maximum
Power Point Tracking (MPPT)
Output of solar
array had characteristics of nonlinear. Output affected by
sunrays, ambient temperature and loadings, and output power of
solar array can be maximized at a certain output voltage only.
Solar array output power operating at peak voltage output which
we called MPP-maximum power point. For more effectively operate
for solar array, it’s important for track down max output power
of solar array.
Shengyang samll
power inverter MPPT operating principle: in a specified period,
MPU actively adjustable for PWM’s duty ratio regularly, changing
output current of solar panels and leading to output voltage
changing, checking output voltage and output current of solar
panels, computing output power of solar array, then track down
max power point managing by maximum power point tracking
strategy.
l         APL
(Power Automatically Locked)
When MPPT track
down the max power point, inverter will be operating of locking
in max power point automatically, so as to keep operating max
power output of DC power supply device within a corresponding
period and achieve more stable output power.
l         Automatically
Adapt To Different Power Loading
Adapt to
different power loading because of Synchronism in same frequency
between inverter output and power grid. Such as inductive load,
resistive load, soluble load.
l         Constant
Current, Constant Power, Current Limiting Protection
Synchronism in
same frequency between inverter output and power grid, follow up
power grid and take power grid as strong backup to achieve
constant current, constant output power, without any overload and
any over-current.
l         Automatically
Turn Off and Stop Output When Fault of Grid(Islanding
Protection)
When there is
fault or outage of electricity power grid, inverters will be turn
off automatically and stop operating within 0.5 second.
l         Inverters
Stacking (online in parallel installation of inverters
using)
Large output
power can be operating by stacking inverters in parallel
installation method.
l         High-Frequency
High Conversion Rate (>*0%)
Adopting magnetic core
which import from Janpan for inner transfomer. High conversion
and less loss make higher efficiency of output.
