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:What is the difference between low voltage grid connection and medium voltage grid connection?
The difference is that the current at low voltage and the grid is large, the current is small when the voltage is small, followed by the low voltage crossing parameter setting problem (such as PV inverter integrated with inverter and low voltage crossing function, not all photovoltaic inverter
Q:Is the PV inverter a current source or a voltage source?
Photovoltaic inverter, also known as power regulator, according to the inverter in the use of photovoltaic power generation system can be divided into two kinds of independent power supply and 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: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: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:What is the PV inverter starting voltage
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power. Generally consists of boost circuit and inverter bridge circuit. The boost circuit boosts the DC voltage of the solar cell to the DC voltage required for the inverter output control. The inverter bridge circuit converts the boosted DC voltage to the AC voltage of the common frequency. 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. Of course, it is not practical to simply output the inverter output waveforms from the on and off circuits
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.
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
