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:Grid-connected inverter is generally divided into photovoltaic power generation grid-connected inverter, wind power grid-connected inverter, power equipment and grid-connected inverter and other power generation equipment power generation inverter.
Grid-connected inverter is generally used with large-scale photovoltaic power plant system, a lot of parallel PV string is connected to the same set of inverter DC input, the general power of the use of three-phase IGBT power module, power
Q:Is the grid side of the grid and the inverter?
The grid load side of the grid is the grid. The inverter is an important part of the PV grid-connected system and can not be regarded as an external load. Photovoltaic power generation system is included in both grid and off-grid.
Q:The working principle of photovoltaic grid - connected inverter
In the small-capacity inverter generally push-pull inverter circuit, full-bridge inverter circuit and high-frequency step-up inverter circuit three, push-pull circuit, the step-up transformer neutral plug connected to the positive power supply, two power Alternating current, the output to get AC power, due to the power transistor to ground, drive and control circuit is simple, and because the transformer has a certain leakage inductance, can limit the short circuit current, thus improving the reliability of the circuit. The disadvantage is the low utilization of the transformer, driving the emotional load is poor.
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 is the difference between a PV grid-connected inverter and an off-grid inverter?
Offline generally need energy storage, not to send energy online. Power grid has no right to interfere.
Q:The function of photovoltaic grid - connected inverter
Finally, a sinusoidal AC output for a grid-connected photovoltaic power generation system is generated by a low-pass filter.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
In foreign countries due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work.
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:Photovoltaic grid-connected inverter problem
But Baidu Encyclopedia clearly pointed out: the zero line is the secondary side of the transformer leads the neutral point of the line, and the phase line constitutes a circuit for power supply equipment.
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!
