On grid inverters are also called grid tie inverters, which are generally divided into solar PV power generation on grid inverters, wind power generation grid tie inverters, power equipment generation on grid inverters, and other equipment generation grid tie inverters. The biggest advantage of on grid inverter is the high power and low cost of the system.Grid tie inverters are generally used in the system of large-scale solar photovoltaic power stations. Many parallel photovoltaic strings are connected to the DC input of the same centralized inverter. Generally, three-phase IGBT power modules are used for higher power, and field effect transistors are used for lower power. At the same time, it uses a DSP conversion controller to improve the quality of the generated power, making it very close to a sine wave current.
Solar companies have some trading skills that you must understand when purchasing solar systems. Let's take a look at them
1. Buy today or the biggest tomorrow and you'll get a very high special discount. This is a famous saying in the tactics of solar energy company. In this case, if you think it's a good deal, then you have to study the offer very carefully, ask the solar company a time, don't sign before you are completely sure.
2. Another tricky sentence is: the big rebate will end next week, which is almost incorrect, because in the past, the rebate was changed regularly, but now it doesn't happen anymore, because the rebate is in the form of solar energy certificate, which has become a consistent plan.
An important question that we must get an answer before installing a new solar photo-voltaic (pv) system: who will be responsible for installing the energy meter to measure how much electricity our solar system is generating, how much electricity our house is consuming, and how much electricity our solar system is exporting to the grid?
When installing solar photo-voltaic (pv) system on the roof of your new home, you need to be careful about shading.
In addition to some other costs that must be noted, there are 2 main categories of costs associated with the installation of solar PV systems, as they may not be identified prior to installation and suddenly discovered after installation.
There are a multiple of inquiries we have to get answers for from our electricity retailer when we intend to install a new solar photo voltaic system. In general, our solar installation company will know the answers of these inquires, but better to ask the retailer, and here are some of these inquires.
In general, the amount of sunlight a solar panel receives in a day is expressed in terms of peak solar hours. It means how many hours of rated power the solar panel can deliver on an average day. For example, if we have a solar panel rated at 450W and the site has 4 hours of peak sunlight, this means that we can supply this solar panel with about 4 x 450 = 1800W hour of energy per day, or 1.8kWh.This is because the amount of electricity a solar panel can produce is directly proportional to the amount of solar energy it receives, so it is important that our solar panel is installed in a direction that collects most of the direct sunlight.

Different voltage power inverter have different prices. Power inverter is a device that can convert DC (the battery and accumulator jar) into AC (normally the sinusoidal wave of 220V and 50Hz). It is composed of inverter bridge, control logic and filter circuit. With a power inverter, direct current (battery, switching power supply, fuel cell, etc.) can be converted into alternating current to provide stable and reliable power protection for electrical appliances, such as laptops, mobile phones, handheld PCs, digital cameras, and various instruments. Inverters can also be used with generators, which can effectively save fuel and reduce noise. The power inverter has a wide range of uses. It can be used in various vehicles, such as automobiles, ships and aircraft.
First Phenomena: Its yellow and brown colors appear internally in the solar panel. Due to solar panel poor manufacturer understanding of material science, there will be unusual chemical reactions happened internally and cause the rear white plastic to turn to brown or yellow, also, this may happen to solar cells surface due to chemical reactions between silicon cell surface and chemicals used to treat the solar panel glass.
Solar inverter is a main device and important part of PV on grid power system. In order to ensure the normal operation of the solar PV grid tie system, the correct configuration and selection of solar inverters are particularly important. For the configuration of the solar inverter, in addition to considering the technical specifications of the entire photovoltaic power generation system and referring to the product manual, the following technical features should also be considered: rated output power, output voltage adjustability, overall efficiency and start-up performance.
Solar panels like any other product are Not the same, as some solar panels manufacturers use the high quality equipment and materials in manufacturing process, while others do Not. The used high quality materials will lead to high solar panels performance and high reliability. Those solar products manufacturers who always conduct researches to develop their solar panels manufacturing process are absolutely the best for us to buy from even their prices may be a bit higher than others.
Those are 3 important components in any solar panel with high influence on solar panel quality, performance and life span. So, let us show their effects and how can we choose the best characteristics as following:
Sine Wave Inverter vs UPS
-Saturday, February 27, 2021
An inverter is a device composed of inverter device and component, which is directly different from a transformer. In other words, the inverter can realize DC input and then output AC. The working principle is similar to that of a switching power supply, but the oscillation frequency is within a certain range. For example, if the frequency is 50Hz, the output will be AC 50Hz. An inverter is a device that its frequency can be changed. UPS (Uninterruptible Power System/Uninterruptible Power Supply) is system equipment that connects batteries (mostly lead-acid maintenance-free batteries) with the host, and converts DC power into mains power through module circuits such as the host inverter. It provides uninterrupted power, and is mainly used to some equipment that requires high power supply stability.
Centrifugal pump is a pump that relies on the centrifugal force generated when the impeller rotates to transport liquid. What causes the centrifugal pump to fail to deliver water? Here are the failure analyses.
1. Some users do not fill enough water before the pump is started. Sometimes it seems that the water filled has overflowed from the vent hole, but the pump shaft is not rotated and the air is completely discharged, causing a little air to remain in the inlet pipe or pump body.
The solar inverter is the safety control center of PV system. Thus, during the PV system operation, the inverter condition, including the temperature and operation of interval cavity and main element, the bus voltage and the communication among chips, shall be inspected from time to time. In addition, the insulation among components and DC system, the DC voltage and current, the AC output voltage, current and frequency shall also be inspected. In case of any failure, it shall be solved in time.
The difference of series inverter and parallel inverter is that they use different oscillation circuits. The series inverter connects L, R and c in series and parallel inverter connects L, R and c in parallel.
Series Inverter vs. Parallel Inverter
The load circuit of series inverter has low impedance. The voltage source power supply is required and the large filter capacitor shall be connected at the DC power terminal in parallel. If the inverter fails, it is difficult to provide protection because of large surge current. The load circuit of parallel inverter shows high impedance and the current source power supply is required. The large reactor shall be connected at the DC power terminal in series. If the inverter fails, it is easy to provide protection because the large inductor can limit the current so as to avoid large impact.
