    Q 1. what's the payment term?  

    A. We accept TT,30% deposit and 70% balance agaisnt copy of BL

     

    Q 2. how's the delivery time ?

    A. usually it will take about 25 days for production

     

    Q 3. tell me the standard of package?

    A. For the small capacity, it use carton, but for big capacity, we will use strong wooden case for protection.

     

    Q 4. what kind of material of transformer?

    A. we have two types, one 100% copper and the other is copper with aluminum.It depends on your requirment. In fact,those two have no difference if normal work well. Only except the longlife. Copper is better and also higer price.

     

    Q 5.Could you offer Form A or C/O ?  

    A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.

     

    Q 6.Would you accept to use our logo ?

    A.If you have good quantity,it absolute no problem to do OEM.

     

    Q 7.We want to know month capacity.  

    A. It depends on which model.For example for relay type small capacity , month capacity can reach near 20000pcs   and big capacity near 3000pcs.

     

    Q 8.Where is your market?

    A. Our products are popular in russia, indonisia, Philippines,italy, america, pakistan and so on.Some of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.

     

     

    Q9. what kind of certificate you have ?

    A. Our company already achieve ISO, CCC, and for products, we have CE, TUV, SAA, G58, C10/11,SONCAP, GOST, UL(pending) .

    Q:What are the methods of photovoltaic grid-connected inverter control
    Sine wave output inverter control integrated circuits, sine wave output of the inverter, the control circuit can be used microprocessor control, such as INTEL company produced 80C196MC, Motorola produced MP16 and MI-CROCHIP company PIC16C73 and so on, these single-chip microcomputer has a multi-channel PWM generator,
    Q:What is the difference between a PV inverter and a solar inverter?
    The main component of the inverter is the three-phase bridge converter. The main purpose of the grid-connected inverter is to change the power to DC and change the AC power. The main purpose is to improve the power quality (because the wind power generation is very large
    Q:What is the difference between low voltage grid connection and medium voltage grid connection?
    The difference is that the current at low voltage and the grid is large, the current is small when the voltage is small, followed by the low voltage crossing parameter setting problem (such as PV inverter integrated with inverter and low voltage crossing function, not all photovoltaic inverter
    Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
    Grid-connected inverter can be operated locally through the LCD screen, or through remote monitoring with dedicated monitoring software.
    Q:The working principle of photovoltaic grid - connected inverter
    Inverter will be converted into alternating current DC, if the DC voltage is low, then through the AC transformer boost, that is, the standard AC voltage and frequency. For large-capacity inverter, because the DC bus voltage is high, AC output generally does not require transformer boost that can reach 220V, in the small and medium capacity of the inverter, because the DC voltage is low, such as 12V, 24V, It is necessary to design a boost circuit.
    Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
    Inverter is the DC power (battery, battery) into alternating current (usually 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioning, home theater, electric wheel, power tools, sewing machines, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, video recorders, massage, fan, lighting and so on. In foreign countries
    Q:PV grid-connected inverter and independent inverter in the control of what is the difference
    Photovoltaic grid-connected inverter is the assembly of the DC into AC power for the use of load, or do not use the load, the inverter after the AC power to the city power grid, when the electricity outage, the inverter will automatically
    Q:Photovoltaic grid-connected inverter without DC emc how will happen
    When solar or other light illuminates the PN junction of the semiconductor, a voltage (called a photogenerated voltage) occurs on both sides of the PN junction. This phenomenon is the famous photovoltaic effect.
    Q:In a photovoltaic grid-connected project, the role of the inverter is to convert the voltage into AC 220V or 380V for the grid, since the transformer will raise the voltage again
    Part of the distributed grid-connected projects, the basic are "spontaneous use, the power of the Internet," these do not need to boost, because the extra power is actually consumed by the surrounding electricity users, do not boost to a Level power grid;
    Q:Generally a large grid-connected photovoltaic power plant will have several inverters
    , This method is simple to design, easy maintenance, but also for the power grid harmonics smaller, good power quality!
