FAQ

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
inverter). Then you have to dimension your PV array (Voltage and Current).

Does inverter long warranty mean high quality?

SMA did bump up the warranty to 10 years when CSI demanded all inverter manufacturers to do so. The European Sunny Boys are only warrantied for 5 years. 

iPhones only have a one year warranty. Does that mean Apple products aren't reliable? Enphase offers a 25 year warranty on their
ibut only one year on their inverters monitoring. Does this mean their monitoring is not as reliable as their inverter? Of course not. 

Offering long warranties have very real costs, especially for publicly traded companies like SMA. If we were to offer a 25 year warranty, we would have to hold a higher reserve on our balance sheet, making our products more expensive. We think that our customers would rather have our high quality products at a lower cost.
 

Start-ups invariably offer long warranties to make up for lack of track record or the perception of quality problems. As the unfortunate recent events at Solyndra have
shown, long warranties offered by start-ups can have limited practical value. 

Analogies can be drawn to the wind industry: in the early days, customers requested very long warranties (20 years or so), since it was the wild west and no one had a clue about long term O&M requirements for these big new turbines. Now that the wind industry has matured, turbine warranties are again very short (2 years is typical) since the large suppliers have a track record of shipping quality product that does not fail when properly maintained. You could say that PV today is like the wild west environment in wind 10 years ago.

Q:What are the methods of photovoltaic grid-connected inverter control
Sine wave output inverter control integrated circuits, sine wave output of the inverter, the control circuit can be used microprocessor control, such as INTEL company produced 80C196MC, Motorola produced MP16 and MI-CROCHIP company PIC16C73 and so on, these single-chip microcomputer has a multi-channel PWM generator,
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 PV inverter a current source or a voltage source?
For the inverter for the grid system, depending on whether the transformer can be divided into transformer-type inverter and transformer-free inverter.
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: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:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
The solar grid-connected inverter is not connected to the grid and can not be directly connected to the load to supply power to the load because there is no voltage.
Q:After the PV inverter, how to achieve the same period before the network?
Grid simulator: analog power grid, normal and abnormal conditions, overvoltage, undervoltage, over frequency, under frequency, sudden power failure, etc.
Q:Photovoltaic grid-connected inverter problem
The first zero line is the AC output. Any AC output of the inverter will have zero line, whether it is isolated or non-isolated. Isolation is the safety of high voltage inverters and regulators. 50KW above the inverter almost with the transformer.
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
Unless the power is not issued for their own use, is to be sent to other areas, it needs to boost, such as the western region of those large power stations
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
