1.   Structure of Off Grid 1000W DC 12/24V to AC 110/220V Pure Sine Wave Inverter Description

A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical 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.

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:Installation and maintenance of photovoltaic grid - connected inverter
Before making an electrical connection, be sure to use the opaque material to cover or disconnect the PV panel. Exposure to sunlight, photovoltaic arrays will produce dangerous voltages. All installation operations must be done only by qualified technicians.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
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.
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:Is the PV inverter a current source or a voltage source?
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power.
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: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:Generally a large grid-connected photovoltaic power plant will have several inverters
, This method is simple to design, easy maintenance, but also for the power grid harmonics smaller, good power quality!
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
Part of the distributed grid-connected projects, the basic are "spontaneous use, the power of the Internet," these do not need to boost, because the extra power is actually consumed by the surrounding electricity users, do not boost to a Level power grid;
