    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
    and can set the dead time between the upper and lower arms, the use of INTEL 80C196MC to achieve sine wave output circuit, 80C196MC to complete the sine wave signal, AC output voltage, to achieve regulation. Circuit output generally use LC circuit filter high frequency wave, get pure sine wave.
    Q:What is the difference between a PV inverter and a solar inverter?
    Instability, the wind speed and the equipment itself will directly affect the generator rotation, so the voltage and current fluctuations, frequency instability, in short, is the power quality is poor) Therefore, through the inverter after the first rectification inverter to improve the quality of power
    Q:Is the PV inverter a current source or a voltage source?
    The inverter is mainly composed of a switching element such as a transistor, and turns the DC input into an AC output by repeatedly turning ON-OFF the switching element in a regular manner.
    Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
    In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC grounding
    Q:PV grid-connected inverter can directly load it?
    Grid-connected inverter is like a car file, he first detects the grid waveform, can not detect not boot, and then the PV DC modulation and consistent with the grid waveform, and then hang up.
    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:What is the difference between a PV grid-connected inverter and an off-grid inverter?
    Off-grid inverter is equivalent to their own to establish an independent small power grid, mainly to control their own voltage, is a voltage source.
    Q:After the PV inverter, how to achieve the same period before the network?
    Grid simulator: analog power grid, normal and abnormal conditions, overvoltage, undervoltage, over frequency, under frequency, sudden power failure, etc.
    Q:Photovoltaic grid-connected inverter problem
    The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
    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
    Connected to the grid is connected to which specific location ah? Transformer is to buy a separate, or buy inverter inside the type of transformer? For example, Sweden's 15KW and 30KW grid roof projects, the roof, for example, more remote to be transported to other electricity.
