System Function

◆ Power line carrier-current communication(this is optional function,please confirm the spec outside the box first .)

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.

.

: :

：

◆ 6-grade power search--- 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 .

◆ Wide voltage input(22-50VDC)--- 1.DC voltage input:22~50VDC; 2.Second level power variable voltage conversion.

◆ High-frequency two-way and one-way grid function--- 1.High frequency direct modulation, AC half wave synthesis;

2.Two-way grid means: Load consume directly. And can reverse AC current transmission.

◆ Kinds of frequency output function--- 1.It can apply to 50Hz and 60Hz frequency of AC; 2.Frequency range: 45Hz ~ 64Hz;

◆Directly connected to the solar panels (do not need to connect the battery)

◆ AC 0 angle with high precision auto-detection--- 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.

◆ Synchronous High-frequency Modulation

1.Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz) ;

2.Synthetic way: MOSFET full-bridge; 3.High frequency: 50KHz.

◆ Pure Sine Wave Output--- 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.

◆ Power Automatically Locked (APL)--- automatically powers locked in maximum power point, made output more stable.

◆ Constant Current, Constant Power--- constant current and output power, without any overload, over-current phenomenon.

◆ Exactly and timely automatic Island Effect Protection

◆ High-Frequency High Conversion Rate--- Adapt high frequency converter, the output more efficient .

◆ Maximum Power Point Tracking (MPPT)--- 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.

◆ Stack using--- Such as: 4 micro inverter of 260W stacking can achieve 1040W. the number of the stacking is unlimited.

◆ DC input--- 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.

◆ AC output--- 220VAC: 180V - 262V, 50HZ; 110V AC: 80V - 160V ,60HZ.

Notes:

★Please connect the inverter following the operation instruction show above. If have any question please contact

with relative persons.

★ Non-professionals do not disassemble.Only qualified personnel may repair this product.

★ Please install inverter in the low humidity and well-ventilated place to avoid the inverter over-heating,and clear

around the inflammable and explosive materials.

★ When using this product, avoid children touching,playing, to avoid electric shock.

★ Connected solar panels, battery or wind generators DC input DC power supply cable.

Accessories for product:

1.One warranty card;

2.One user manual;

3.One certificate of quality;

5.One AC Cable;

LED Display

1.Red light 3 second---Red LED light 3 second while device starts , then in working condition;

2.Green flash fast---MPPT searching;

3.Green flash slow---MPPT + searching;

4. Red flash slow---MPPT - searching;

5.Green lights on 3s and off 0.5s---MPPT locked;

6.Red light steady---a. Islanding protection;b.Over-temperature protection;c.Over / low AC voltage protection;

d. Over / low DC voltage protection; e.Fault

Remarks:

LED flashing in the process of being working condition:inverters connected to AC & DC sides→Red LED light 3 second→Green LED flash fast(MPPT searching)→Green LED flash slow(MPPT + searching) / Red LED flash slow

(MPPT - searching) / reen LED lights on 3s and off 0.5s (MPPT locked) .
