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
photovoltaic systems Power generation system used in the cable must be connected firmly, good insulation and specifications appropriate.
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid 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:The working principle of photovoltaic grid - connected inverter
Full-bridge inverter circuit to overcome the shortcomings of the push-pull circuit, the power transistor to adjust the output pulse width, the output AC voltage RMS that changes. Since the circuit has a freewheeling circuit, even if the inductive load, the output voltage waveform will not be distorted. The disadvantage of this circuit is that the upper and lower arms of the power transistor are not common, so you must use a special drive circuit or use isolated power supply. In addition, in order to prevent the upper and lower arm co-conduction, must be designed to turn off after the conduction circuit, that must be set dead time, the circuit structure is more complex.
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: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:PV grid-connected inverter can directly load it?
Converter is the AC voltage of the grid into a stable 12V DC output, and the inverter is the AC output of the 12V DC voltage into high-frequency high-voltage alternating current; two parts are also used with more pulse width
Q:After the PV inverter, how to achieve the same period before the network?
It can automatically detect the generator and the grid frequency and voltage, in the frequency, voltage, phase are in line with the requirements of the grid to set the time before the release of the closing signal, so that it can be safely and securely connected.
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
Have a low pressure through the function set, low pressure through the scope of the project requirements, grid and network requirements and the actual situation of the design), low voltage grid to pass the voltage range is less than the medium pressure, parameter settings are not sensitive and complex.
Q:Is the grid side of the grid and the inverter?
Grid-type system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load + power grid (both in parallel).
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!
