By using electric power as a carrier of AC alternating current, can modulate high-frequency and carrier frequency (60KHz) in AC
wire transmission and can achieve the communication/ newsletter between inverters or between inverter and computer. And it
can transfer the power data . Also monitor all functions of inverter.
1.Carrier frequency 60KHZ(Frequency customizable); 2 Interface way TTL level serial interface; 3.Carrier rate 300BPS;
4.Serial rate 9600PS(Can customize according to customer's request);
5 Modulation mode FSK+DSSS; 6.Newsletter distance:400m;
In overcast weather, the PV Panel’s output current is extremely tiny, then inverter will automatic
open 6-grade power search function,and keep outputing efficent and steady during the low power .
1.DC voltage input:22~50VDC; 2.Second level power variable voltage conversion.
1.High frequency direct modulation, AC half wave synthesis;
2.Two-way grid means: Load consume directly. And can reverse AC current transmission.
1.It can apply to 50Hz and 60Hz frequency of AC; 2.Frequency range: 45Hz ~ 64Hz;
High-precision analysing the AC phase angle .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: 50Hz / 60Hz.
1.Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz) ;
2.Synthetic way: MOSFET full-bridge; 3.High frequency: 50KHz.
Use SPWM directly to make pure sine wave output.
1.Output waveform: Adopt complementary PWM to push-pull pure sine wave; 2.Generate means: enhancement-mode SPWM.
automatically powers locked in maximum power point, made output more stable.
constant current and output power, without any overload, over-current phenomenon.
Adapt high frequency converter, the output more efficient
high-precision (MPPT) operation power, automatic and immediate adjust the solar
panels output power at the maximum output point,made the inverter discharge to power grid with the highest efficiency.
Such as: 4 micro inverter of 260W stacking can achieve 1040W. the number of the stacking is unlimited.
Input voltage range: 22V to 50V,PV Panel: Recommend using the power more than 30W and the standard voltage
of 36V PV panels.Suggestion making the PV in parallel.
220VAC: 180V - 262V, 50HZ; 110V AC: 80V - 160V, 60HZ.
