And it can transfer the power data and the brightness date of the sunshine in the real-time. Also monitor all functions of inverter.1、Carrier frequency：60KHZ（Frequency customizable）2、Interface way：TTL level serial interface3、Carrier rate：300BPS4、Serial rate：9600BPS（Can customize according to customer's request）5、Modulation mode：FSK+DSSS6、Newsletter distance：2Km●Display function1、AC voltage display2、Outage display3、Power shows4、AC frequency display5、DC over-voltage display6、DC under- voltage display7、Power adjust display●12-grade power searchIn overcast weather,the solar battery’s output current is extremely tiny, then inverter will automatic open 12-grade power search function.1、The program can automatically open power adjustment for 12 times.2、The current direction can adjust from the maximum to the minimum.3、In automatic adjustment process, we will see the LOW light flashing.And the power will keep as a starting point,from 0 to the maximum output power, and it will restart at most for 12 times, then locked in the maximum power, the ST lamp long bright.4、It need 10 minutes for 12-grade power search.●Wide voltage input(15-60VDC）Achieve wide voltage input.1、DC voltage input：15-60VDC2、Second level power variable voltage conversion●High-frequency two-way and one-way grid function1、High frequency direct modulation, AC half wave synthesis2、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.●Kinds of frequency output function.It can apply to 50Hz and 60Hz frequency of AC.Frequency range: 45Hz ~ 63Hz●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.1、Differential pressure type MPPT: 0.1 V accuracy2、Power lock: 10W (AC output)●AC 0 angle with high precision auto-detectionAC phase angle of 0 through isolation amplifier then input 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 output together.1、AC phase shift: < 1%2、Over-zero protection: 0.2 V AC3、AC switching: 50Hz / 60HzSynchronous High-frequency ModulationIn the process of the grid, usually adapt the same phase angle in parallel. (ie, When the two-phase alternating current total is equal to e switch to combination the two AC fusion) and the product is rectified AC half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.1、Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz)2、Synthetic way: MOSFET full-bridge3、High frequency: 50KHzPure Sine Wave OutputUse 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●Automatic Sensing Function Solar LuminosityUse 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 point ：power sampling point2、High precision AD sampling: integral AD sampling methodPower 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.1、Power lock: The biggest sampling point of MPPT.Automatically Adapt To Different Load Power FactorAdapt to any of the power load.●Constant Current, Constant PowerThis product is constant current, constant output power, without any overload, over-current phenomenon.●Automatically Shut Down When The Power Output Of a FaultWhen the city power system is in failure, the inverter will automatically turn off the output.Current Limit ProtectionCurrent limit●Stack Multiple Machines●Multiple small power inverters in parallel can achieve large output power.●High-Frequency High Conversion RateAdapt high frequency converter, the output more efficient.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.The peak voltage (Vpp) of the solar panels is about 19.5V when it in factory. And the environment temperature is 25 ° C. The reason of setting this temperature(interestingly, different from the subjective imagination, we ordinary people the conclusion may let us surprised) is that when the weather is very hot, solar panels’ peak voltage will fall to about 17.5 V while in cold weather, the peak voltage can achieve 20.8 V.Now we back to contrast the difference of MPPT solar energy grid inverter and traditional inverter. The traditional solar inverter is a bit like the manual gearbox. When the engine speed increase, while the gearbox gear don't increase at the same time, it will definitely affect the speed of the car. For traditional inverter speaking, the parameter output power is been set in factory. It likes a car have been fixed set on fixed 1 gears, no matter how powerfully you trample accelerator, the speed of a car is limited. While have the MPPT function it will be different, it is automatically. It will automatically adjust the gears according to the engine’ speed, so it can make cars in the most gears in a reasonable efficiency standard operation. It means the MPPT controller can track the maximum power point of solar panels in real-time then express the biggest efficiency of solar panels. The higher the voltage, the more power can be output through the MPPT. Thus improve the charging efficiency.Theoretically speaking, using MPPT, the efficiency can be increased by 50% compared with the traditional inverter. But due to environmental impact and various around energy loss, the ultimate efficiency can improve20%-30% according to our actual testing.Parameter TableKD-WVC Grid-series models300Watt 500Watt Recommend use solar panels400Wp 600WpDC MAX input current 20A 40AAC MAX output power 300Watt 500WattDC MAX Open-circuit input-voltage 100VDCDC input voltage range 15~60VDCMAX output power factor 0.99DC input Reverse voltage protection FUSEAC output voltage range （120V versions：90~160VAC）（230V versions：190~260VAC）AC frequency range 45~63HzOutput current total harmonic distortion THDIAC <5%AC Phase <0.5%Islanding protection V AC；f ACOutput short circuit protection Current-limitingShow LED mode：power instruction；voltage instruction；AC frequency instruction；over-voltage instructionCommunication way 60KHz modulation，power line carrier-current communication Standby Power <1WNight Power <1WAmbient temperature range -25 ℃~60℃Humidity 0~99%(Indoor Type Design) Waterproof Indoor Type Design Electromagnetic Compatibility EN50081.part1 EN50082.part1 Power System Disturbance EN61000-3-2 EN62109 Network test DIN VDE 1026 Certificate CEPacking and weightNet weight 1.3kg（200—600W） 2.0kg(800—1000W) G weight 2.0kg（200—600W） 2.7kg(800—1000W) Size (L x W x H) 21 x 16.5 x5.3cm 31 x 16.5 x5.5cmPackage (L x W x H) Inner box:34x25x15.5CMBig box:51x37x33CMInner box :43x25x15.5CBig box:52x45x33CMInstallation Wall hanging AC power cord length 1.8m Cooling FanUser Guide1、Installation Connection1、Red terminal: Connect DC positive, black terminal: Connect DC negative.

50KW光伏系统安装调试手册光伏系统的安装主要分为光伏支架、组件的安装，配套电缆的铺设，汇流箱及交直流柜的安装，逆变器的安装几大部分。
一、光伏组件支架的安装：光伏组件支架经甲方、专业监理单位验收合格后进行现场安装。
工程用支架为铝合金以及热镀锌钢材。
施工时2人一组配合施工，施工过程中尽量避免铝合金表面及镀锌层被尖锐物体划伤。
安装时要有序进行，把转接件（与屋面板连接用）、主龙骨、次龙骨（如需要次龙骨）等部件分开堆放，统一吊装。
按照每排的光伏组件数量计算每排的正确用料数量，包括螺栓等相关配件用量。
先把转接件固定在直立锁边屋面板上，然后在其上固定相应的主龙骨和次龙骨（如需要次龙骨），然后把各部件用螺栓固定连接在一起，螺栓先手动收紧，后用手动扳手或电动扳手紧固，同时用尼龙线观察并调节其直线度。
安装结束后清理现场包装物。
二、光伏组件的安装光伏组件经甲方相关负责部门验收合格后方可使用，施工时3人一组配合施工。
工程所用光伏组件上表面为3.2mm厚钢化玻璃结构，且屋顶结构只允许单块光伏组件单层排布，因此屋顶上不允许多层堆放。
堆放前先检查屋顶是否平整，且其上无尖锐物体，同时保证楼面局部的承受力，屋顶防水结构层不受损坏。
在搬运安装时要小心轻放，避免光伏组件和光伏组件、光伏组件和支架间的碰撞。
光伏组件安放于龙骨上，采用紧压方式固定。
紧压要适中，既满足光伏组件及支架的防风，防震，同时，不能因压件过紧损坏玻璃，造成不必要的损失。
光伏组件的摆放要整齐，接线盒的位置要统一在上端面。
三、电缆线的敷设电缆线的敷设应由远至近顺势排放，电缆短距离搬运，一般采用滚动电缆轴的方法。
电缆引出端应在轴的上方。
牵引时减少与地面的摩擦。
排放前先安装固定好相应大小的电缆桥架，每根线都必须拽直，不得扭曲打结。
电缆在汇流箱及直流配电柜的两端都必须留有足够的接线长度并在线端贴上标签做好标记。
电缆线在穿越道路时要加穿钢管做防护套，防护套的管口在切割后要去除毛刺和快口以防止电缆线在拖拉时被割破。
