★System
Function
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.
