FAQ

 

1. Have any design tool and how to use it?

Shine Design is the system design software just for inverters, It can conduct installers to figure out panel numbers for a system, panel numbers for each string, and which inverter model is suitable for the system. Moreover, it can print a design report after input all necessary parameters, can calculate DC/AC wire wastage, annual generation, etc.

 

2. Does the inverter have monitoring solutions for residential system?

For small rating system, we have wired two monitoring solution (ShineNet via RS232 or RS485). (a) Local wireless monitoring solution (ShineVision via RF module communication) (b) Global wireless monitoring solution (WIFI module via WIFI network)

 

3. Do you have free solution for monitoring?

ShineNet is an inverter monitoring software run in Windows XP, Windows Vista, Windows 7 operating system. It can monitor inverter via RS232 (or RS232 convert to USB cable) and RS485 wire connection. Customers can purchase the cable locally to get the inverter monitored, it is simple.

Q:Installation and maintenance of photovoltaic grid - connected inverter
only when the local power sector permission by the professional and technical personnel to complete all the electrical connection before the inverter can be connected.
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, how much light to send online to the number of online, simply do not want people to the grid does not like.
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:What are the methods of photovoltaic grid-connected inverter control
The square wave output of the inverter using pulse width modulation integrated circuits, such as SG3525, TL494 and so on. Practice has proved that the use of SG3525 integrated circuits, and the use of power FET as a switching power components, to achieve high performance of the inverter, because the SG3525 has a direct drive power FET capability and has an internal reference source and operational amplifiers and Undervoltage protection, so its peripheral circuit is very simple.
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:What is the PV inverter starting voltage
The inverter not only has the function of direct current conversion, but also has the function of maximizing the performance of the solar cell and the system fault protection function. (With grid system), automatic voltage adjustment function (for network connection), DC detection function (for network connection), DC grounding detection (for network connection), automatic power control function Function (for grid connection). Here is a brief introduction to automatic operation and shutdown function and maximum power tracking control function.
Q:Photovoltaic grid-connected inverter problem
Hello, the definition of the zero line is not caused by the transformer three-phase electric tail connection? I now do not understand why there is no isolation transformer AC output marked is N (zero line), and it is not the transformer three-phase power of the tail connection leads to, this is the zero line? The The
Q:After the PV inverter, how to achieve the same period before the network?
When the voltage, frequency, phase does not meet the requirements, the automatic closing closing pulse.
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:The function of photovoltaic grid - connected inverter
In general, single-phase h-bridge is a common configuration of dc / ac-level, but can also be used in three-phase and other configurations.
