    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 is the PV inverter starting voltage
    sine wave becomes narrower and the voltage width in the center of the sine wave is widened and the switching element is always operated in a direction at a certain frequency in a half cycle, A pulse wave train (pseudo sine wave). Then let the pulse wave form a sine wave through a simple filter
    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:Installation and maintenance of photovoltaic grid - connected inverter
    Before the installation should first check whether the inverter in the transport process for damage. When selecting the installation site, there should be no interference with any other power electronic equipment in the surrounding area.
    Q:PV grid-connected inverter and independent inverter in the control of what is the difference
    The independent inverter in the output voltage phase amplitude of the frequency control is initially set good. Independent inverter, you should refer to off-grid inverter, do not need to consider the grid situation.
    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 grid-connected inverter and an off-grid inverter?
    Grid-connected inverter will be directly sent to the power grid, so to track the frequency of the grid, phase, the equivalent of a current source. Of course, there are some inverters called low-voltage crossing ability, you can do PQ adjustment
    Q:Generally a large grid-connected photovoltaic power plant will have several inverters
    The use of a high-power grid-connected inverter into the grid, the need for line design is relatively simple, because the DC and AC lines are separated, the use of convergence box to summarize, DC bus and then into the grid inverter
    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: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:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
    Hybrid inverter is not a clear concept, but now both energy storage dual-grid inverter does have the ability to receive control system,
