Based on trend forces, the sales market of solar power generation in Taiwan was analyzed. In the first half of 2019, AUO ranked second, while third-ranked Canada Solar entered the top three for the first time.
Compared with the previous year, the share of the Taiwan sales market in the total delivery of common renovation in the first half of 2019 decreased by about 10%, indicating that Taiwan has just begun to adjust its rational layout to reduce the proportion of Taiwan. AUO, which is closely following, has increased year-on-year compared to 2018 after adjusting its marketing strategy, and its sales volume has developed significantly.
Originally, the key to the delivery in the first half of the year was donated by the medium-sized project of the service system software manufacturer in Chiayi, and the 150MW target pavement project of the station station Nanqigu obtained in March 2020 was delivered from the third quarter, and the delivery ranking in 2019 is particularly noteworthy.
In addition, Taiwan, China began to apply for the mandatory VPC verification of inverter power supply on May 21 this year, compared with foreign manufacturers, most of the Taiwanese inverter power supply manufacturers have just begun to carry out VPC reasonable layout in 2018, so it can be seen from the sales volume of inverter power supply in Taiwan's sales market in the first half of the year that Taiwanese manufacturers are mainly outstanding. Delta Electronics is still steadily delivering the championship, but except for Delta, the ranking of other manufacturers has changed significantly again in the second place is Huawei, and the third place is Xinwang.
GoodWe has entered the sales market in Taiwan since ancient times, and because it is an early manufacturer that sent VPC, its sales volume rose to the fourth place in the first half of the year. The significant decline in sales volume of SMA in the first half of the year is likely due to the fact that after withdrawing from the Chinese sales market at the end of 2018, the reasonable layout of Taiwan's countermeasures has not been brightly triggered. In addition, there was also a second SATCON in 2018, which had less total sales in the first half of the year due to the lack of VPC and the damage of regional agent adjustment.

The benefits of using an inverter – Delta inverter
1. Speed regulation of general motor: By changing the input voltage and frequency of the three-phase asynchronous motor, its speed can be controlled. Generally, when the motor is at low speed, the temperature rise becomes larger due to the decrease in the power of the cooling fan, and the motor load should be reduced according to the frequency.

Introduction to the basic application of Delta inverter
Generally, household appliances use a single-phase asynchronous motor, which relies on capacitance or resistance to split the phase. Motors are often in a short-term repetitive state (on/off) during operation, such as air conditioners, refrigerators, etc. This will inevitably lead to frequent starting, high noise, short motor life, poor temperature stability and energy consumption.

The reason why the circuit breakers of multiple stages trip together is Delta
Short-circuit maintenance (overload maintenance) is an important function of circuit breakers, and the reason why this function is achieved is that the circuit breaker senses the temperature in the circuit through a thermal iron plate. Once the temperature in the circuit is too high, it is transmitted to the mechanical mechanism in the circuit breaker for trip maintenance.
