Product Description:

1. Structure of Photovoltaic On-Grid Connected Inverter SG1000TS-M PV 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

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 Europe, Middle East Asia, Southeast Asia and Australia.

5. FAQ of Photovoltaic On-Grid Connected Inverter SG1000TS-M PV inverter

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:Installation and maintenance of photovoltaic grid - connected inverter
only when the local power sector permission by the professional and technical personnel to complete all the electrical connection before the inverter can be connected.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
Which depends on the grid inverter in the absence of the grid there is no independent operation of the function of the general grid inverter is the current type, only responsible for the power to the grid, the voltage is maintained by the 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 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: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: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?
Grid simulator: analog power grid, normal and abnormal conditions, overvoltage, undervoltage, over frequency, under frequency, sudden power failure, etc.
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: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.
