Heavy losses, 600 pigs in Chiayi County were electrocuted! How to avoid such security risks?
Recently, according to media reports, the solar power box of Haoyao Livestock Farm in Xikou Township, Chiayi County suddenly exploded due to unknown reasons, causing more than 600 deaths and injuries to 2,000 pigs on the farm. Among them, 250 pregnant sows were electrocuted or paralyzed. ,lost heavily. Talking about the cause of the explosion, the relevant personnel said that a bird corpse was found at the power switch after the incident. The preliminary analysis was that the bird accidentally touched the switch, which caused the solar photovoltaic to be unable to be sent back to the Taipow...Read more -
Do you know how to choose a home charging pile?
Considering the cost, most of the charging piles for household cars are AC piles. So today I will talk about household AC piles, and I will not go into details about DC piles. Before discussing how to choose a pile, let’s first talk about the classification of household AC charging piles by installation method, which are mainly divided into two categories: wall-mounted and portable. The wall-mounted type needs to be installed and fixed on the parking space, and it is divided by power. The mainstream is 7KW, 11KW, 22KW. 7KW stands for 7 kWh in 1 hour, which is approximately equivalent ...Read more -
How To Choose Surge Protection Devices,do you really know？
As everyone knows, surge protection devices or surge protective devices (SPD) protect electrical equipment against over-voltages caused by lightning. That said, it is not always easy to know which to choose. Choosing the right surge arrester and protective circuit breakers involve a considering a wide range of parameters related to types of surge protection devices, circuit breaker arrangements, and risk assessment. Let’s try to see things more clearly… Submit the form, get more about protection device (Circuit Breaker or Fuse) associated with Surge Protective Device. First of all, current ...Read more -
The demand for charging piles in Europe and the United States has exploded, MOREDAY gain new opportunity
According to research by Bloomberg New Energy Finance, if net zero emissions are to be achieved by 2050, it is expected that the cumulative global investment in charging stations will be as high as US$1.6 trillion. Therefore, with the rapid increase in sales of new energy vehicles, the overseas charging pile market is about to explode. The European Commission plans to set tougher climate targets as part of the EU’s Green Deal initiative. In December, EU leaders expressed support for raising targets to cut vehicle emissions by at least 55 percent from 1990 levels by 2030, and the revi...Read more -

MOREDAY Lab: How does an inverter convert DC to AC?
MOREDAY laboratory, help you understand photovoltaic. Today, MOREDAY will work with you to understand the “magic process” of converting direct current into alternating current, and analyze what is the main reason that affects the conversion efficiency of inverters? What are direct current and alternating current? The job of the inverter is to convert the direct current generated by the photovoltaic array into alternating current. First, we need to understand what is DC and AC? ·Direct current (DC): The direction of the current and voltage of the direct current is the same, and...Read more -
What is a solar fuse, include holder and link,let’s take a look！
In 1839, the French scientist Becquerel discovered that light can cause a potential difference between different parts of semiconductor material. This phenomenon is the “photovoltaic effect”. In 1954, American scientists Chapin and Pearson first made a single-crystal silicon solar cell, realizing a technology that converts sunlight energy into electrical energy. Photovoltaic refers to a photovoltaic power generation system, which uses the photovoltaic effect of semiconductor materials to convert solar energy into electrical energy. Solar photovoltaic power generation systems can be divided...Read more -
Fuse Classification: A Variety Of Fuses Have Different Temperature Sensitivity
(1) Classified by structure. According to the structure of the fuse, it can be divided into three types: semi-open type, closed tube type without filler and closed tube type with filler. Filled closed tube fuses are divided into three types: fuses used by full-time personnel, fuses used by unskilled personnel, and fuses used for semiconductor device protection. The fuses used by full-time personnel are divided into knife-shaped contact fuses. There are three types of bolted fuses and cylindrical cap fuses. The fuses used by unskilled personnel are divided into two types: screw type and roun...Read more -
What is a surge protector device and how does it work?
What exactly is a surge protector? A surge protector is a small appliance or device that serves two main functions. The first is to provide the ability to plug multiple components into a single power outlet. The second and more important function is to protect your electronic equipment (such as a TV system or computer) from high voltage power surges. A surge or spike is an increase in voltage in an electrical current above a specified level. How does a surge protector work? A typical surge protector passes current along the outlet to multiple devices plugged into the power strip. If the vo...Read more -
European solar energy production
In the first week of May, solar production in Germany rose by 12% and in the Iberian Peninsula by 2.6%. In Spain, PV and solar thermal energy as a whole totaled 143 GWh on May 6, the highest value in history, largely favoured by high PV energy production, with an instantaneous production of 12 335 GWh on the day . In Portugal, May 7 and 8 were the highest solar production days in history, with a total of more than 10 GWh per day. The French market recorded its third-highest value on record on May 7, at 75 GWh, after 79 GWh on April 26 and 78 GWh on May 1 this year. MOREDAY SOLAR will conti...Read more -
