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 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.

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

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

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:

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

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.

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.
