1.       Structure of Off Grid MPPT Solar Inverter, Solar Pump Inverter 380v 2.2kw 4kw 5.5kw 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.

 

2.       Main Features of the Off Grid MPPT Solar Inverter, Solar Pump Inverter 380v 2.2kw 4kw 5.5kw

﹒ Supports AC&DC input:

DC solar panel input. And If no good sunshine, can use grid  AC regular input work the pumps.

﹒Dry protection :

If no water in the ground, the water pump will stop working automaticly and when the water comes, starts to working automaticly.

﹒Automatic working:

When the sunshine not good then pumps slow down automatically and when sun become good then go on working.

﹒Save cost/directly connect solar panel:

Solar panle connects solar inverter directly and to the pump. Also can control the water level in the tank. No enough water in the tank

working fast, enough water will stop working automaticly. (how many water you need, you can set the parameters)

﹒Speed & frequency control, No need battery:

Q:What are the methods of photovoltaic grid-connected inverter control
Inverter main circuit need to have a control circuit to achieve, generally have square wave and sine wave two control methods, square wave output inverter power supply circuit is simple, low cost, but low efficiency, harmonic components. Sine wave output is the development trend of the inverter, with the development of microelectronics technology, there are PWM function of the microprocessor has also come out, so the sine wave output inverter technology has matured.
Q:What is the difference between a PV inverter and a solar inverter?
The main function of photovoltaic grid-connected inverter is to convert the DC power of the solar PV module into the same frequency as the sinusoidal AC power of the grid (the grid is generally AC power grid, DC can not be directly connected)
Q:Is the grid side of the grid and the inverter?
The grid load side of the grid is the grid. The inverter is an important part of the PV grid-connected system and can not be regarded as an external load. Photovoltaic power generation system is included in both grid and off-grid.
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
Photovoltaic inverters for grid-connected photovoltaic power generation systems are primarily capable of receiving DC power from photovoltaic arrays and converting them into sine-wave currents of the same frequency and in phase with the access grid for powering the grid or local loads.
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 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: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: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: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?
