Central inverter HC2500 KHV grid connected inverter

Huacheng's central inverter is mainly used for outdoor power generation. This product is mainly applicable to large-scale PV station, which takes 2.5 MW as a unit, integrating two 1.25 MW PV grid-connected inverters, communication cabinet (optional), and maintenance power distribution cabinet, etc. Compared with the traditional 1000 V outdoor containerized inverter, it has the advantages of high voltage on DC side (up to 1500 V),which can reduce the current of DC side, increase the output voltage of AC side, improve overall efficiency of the system and generated energy, and reduce system investment cost.

In Europe, all containerized inverters can be widely used, mainly because of their high labor costs, and containerized inverters solve this problem well, requiring only two workers and one engineering hoist Just solve all the problems of building a house. However, the location of European photovoltaic power plants is much better than domestic conditions. The photovoltaic area is allowed to use cultivated land. Those who have been to European photovoltaic power plants will know that their most troublesome problem is the long length of the summer power station. Too long, mowing is a very important job, not the sand between the equipment like the domestic. And there is no desertification in the Gobi, deserts and sandstorms throughout Europe. Therefore, there are not many problems found in its application, and the quality of its containers is much better than that of domestic ones according to the requirements of European products and equipment.
In 2012, due to the Fukushima crisis, Japan accelerated the pace of building a new energy power station and introduced a price of 42 yen/kWh. This has caused Japan to have a wave of looting for nearly a year, but Japan’s construction law provides for To build a home, you have to go through quite complicated and long-term approvals, so complicated that you have to give up this project! Therefore, in order to be flexible, the Japanese also thought of using container-type inverters to solve this problem well. Container-type inverters have been widely used. However, the Japanese are indeed rigorous. In order to solve the problem of heat dissipation of the inverter, air conditioners are installed in the interior of the inverter to dissipate heat, and many modifications have been made to the container inverter. Therefore, it can be said that their containerized inverters ensure the safety and advancement of equipment by reducing power generation and increasing costs.
In China, especially in the northwest, the most important purpose of the development of photovoltaic container inverters is to shorten the electricity price during construction. In addition, due to the generally low labor costs in China, container inverters need to meet the short-term development and low prices. The main ground photovoltaic power plants in China are concentrated in the northwestern region, mainly in Ningxia, Inner Mongolia, Gansu, Qinghai, Xinjiang, etc. The main land types are state-owned unused wasteland, desert and industrial parks, and the equipment use environment is higher than that of foreign countries. The use environment is very harsh, which is contrary to the requirements of the container-type computer room application site, and if you do not pay attention to the impact of the environment on the container inverter, there will be very serious consequences.
