than 8 hours every day, and this is an advantage which is large power inverter cannot be

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. YSmartgrid tie microinverter 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.
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.
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.
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.
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.
High-Frequency High Conversion Rate
Adopting magnetic core which import from Japan for inner transformer. High conversion and
less loss make higher efficiency of output.
