5.  FAQ of Photovoltaic Grid-Connected Inverters SG630MX

Q1. What is the difference between inverter and solar inverter?

    A1. Inverter only has AC inpput, but solar inverter both connect to AC input and solar panel, it saves more power.

Q2. What is the difference between MPPT&PWM?

    A2. MPPT has higher efficiency, it can track the max power point and won't waste energy.

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:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Offline generally need energy storage, not to send energy to the Internet. Grid has no right to interfere.
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:What are the methods of photovoltaic grid-connected inverter control
and can set the dead time between the upper and lower arms, the use of INTEL 80C196MC to achieve sine wave output circuit, 80C196MC to complete the sine wave signal, AC output voltage, to achieve regulation. Circuit output generally use LC circuit filter high frequency wave, get pure sine wave.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, the number of photovoltaic sent to send online how much, simply do not want people to.
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: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?
Solar panel simulator: with MPPT function, simulated morning, noon, afternoon, evening, rainy weather, solar panels produced under different conditions in different voltages.
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: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
