Do you know what are integral parts of a photovoltaic power station?

Power station is high efficiency, high yield, this is every pv owners/investors for concern, but at the same time there are a lot of people pay attention to a basic it is easily neglected problem: security. Unlike independent covers an area of large ground stations,

is whether the plant has a high efficiency and high income each photovoltaic owner/investor concern, but at the same time, many people will focus on a basic but easily neglected problem: security. Unlike independent land at large ground stations, distributed photovoltaic need attached to residential construction, industrial workshop, warehouse, commercial buildings, schools, and municipal construction, etc. These buildings are generally is densely populated, with relevant precise instrument or store with combustible qualitative characteristics. Therefore, distributed photovoltaic need stricter safety performance. Must ensure that the photovoltaic power generation will not affect the function of the original production and life of the buildings, won't cause potential safety hazard to personnel, production and materials. In terms of security, let's look at each country's laws and regulations: in the United States, the fire association revised the national electrical code: 'in the residential photovoltaic power generation system, as an emergency occurs, the interconnection of the communication between the pv system end after disconnecting, not more than 80 v voltage of the DC. In Italy, when building a voltage, firefighters are not allowed to put out the fire. Germany takes the lead in implementing VDE fire safety standards, photovoltaic inverter in the system and components between the need to add a DC cut-off device. Australia, according to OVE R11:2013 specification, near components must have a circuit breaker. Obviously, global photovoltaic power station security priority is the high voltage direct current (dc) in the system. High voltage direct current (dc) can affect not only the rescue work, is also one of the main causes of fire, High voltage direct current) arc 。 Therefore, in foreign countries, only about 40 v DC voltage of the micro inverter has become a hot topic. The security of the micro inverter is not only reflected on the voltage 40 v. It is well known that the industry will be the operation of the photovoltaic power plant life cycle definition for 25 years. In order to ensure the stability of 25 years in power generation, power quality, safety, operation and maintenance is indispensable. Miniature inverter devices have components level monitoring, can be in 25 years of operation cycle real-time observe the operation of the various components. If there is a security failure, the one-time feedback to the big data monitoring platform, to ensure efficiency, improve the security of the whole system.
