1. Structure of Photovoltaic Grid-Connected Inverter SG630MX-E Description

A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into

 autility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

It is acritical BOS–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment.

Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Suitable for 50Hz/60Hz grid, could be used in Asia, Australia and Europe.

5. FAQ of Photovoltaic Grid-Connected Inverter SG630MX-E

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:Is the grid side of the grid and the inverter?
Off-grid system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load;
Q:Is the PV inverter a current source or a voltage source?
According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter.
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: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:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter will be directly sent to the power grid, so to track the frequency of the grid, phase, the equivalent of a current source. Of course, there are some inverters that have a low-pressure through the ability to do PQ adjustment.
Q:PV grid-connected inverter can directly load it?
Grid-connected inverter is like a car file, he first detects the grid waveform, can not detect not boot, and then the PV DC modulation and consistent with the grid waveform, and then hang up.
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
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. According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter. For the inverter for the grid system, depending on whether the transformer can be divided into transformer-type inverter and transformer-free inverter.
Q:Photovoltaic grid-connected inverter without DC emc how will happen
When solar or other light illuminates the PN junction of the semiconductor, a voltage (called a photogenerated voltage) occurs on both sides of the PN junction. This phenomenon is the famous photovoltaic effect.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
Inverter, a single failure, does not affect other operations, the impact on the grid is small, high reliability.
