FAQ

 

Q:Off Grid VS On Grid Panels, what's the difference?

The differences between both panels are related to the system where they are going to be installed. 

On-grid installations, as the name said, are thought to feed the produced energy into the grid and for that it is important to have the biggest voltage that it is allowed (1000VDC in Europe, 600 VDC in USA). For a defined power, more voltage means less current (P=V*I) and less losses.
 

In off-grid installations it is different because you must storage the energy into batteries. Batteries usually work at 12, 24 or 48 VDC and off-grid photovoltaic modules work at the maximum power point (mpp) near this voltage (see the datasheets). So the controller that charges the batteries works also near the batteries voltage.
 

Your limiting factor here is going to be this controller. You have to see what is the maximum voltage and the maximum current that it can work with, upstream (photovoltaic modules) and downstream (batteries and inverters
). Then you have to dimension your PV array (Voltage and Current).

 

Q: Can a solar powered LED lighting without inverter?

Of course you can run lights without inverters. Both LEDs and incandescent lamps are quite happy on DC. And there are fluorescent ballasts that take a DC input (although they do have a sort of inverter inside). I have one in my shed and it has been working just fine for at least 15 years. It is very simple, easy and efficient. You can do away with the electrical code for wiring, lower you cost. Use less energy and lower the cost to install. In fact is we did this to power may of our day to day items we would also lower the demand for power. 

Keep in mind this goes against every manufacturer and government policy and you will be shut down, squashed and run out of town for even talking about this, or at least you used to. I am working on a way to use the current wiring in a home to have direct solar, batter bank lighting. By coming off the grid for your lighting and many other functions, a power outage would hardly make a difference to your home.

Q:Photovoltaic grid-connected inverter without DC emc how will happen
can convert light energy into electricity, so that the current flow from one side to the other, the general can be issued equivalent to 10 to 20% of the received light energy. In general, the stronger the light, the more electricity is generated. Its working principle is based on the semiconductor PN junction of the photovoltaic effect. The so-called photodynamic effect is when the object by the light, the object within the charge distribution of the state of the electromotive force and current generated an effect.
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: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:PV grid-connected inverter and independent inverter in the control of what is the difference
PV grid-connected inverter in the grid before the inverter needs to determine the phase voltage phase frequency, the first phase-locked, in the grid and power generation.
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
By dc / dc conversion to increase or decrease the input voltage, adjust its output to achieve maximum efficiency.
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:Generally a large grid-connected photovoltaic power plant will have several inverters
Group is the use of a number of grid-connected inverter and grid-connected AC power grid, the advantage is the loss of small, low cost of the cable (because the PV cable is more expensive), eliminating the cost of the convergence box, and multiple
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: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.
