PV combiner box

For large-scale photovoltaic grid connected power generation systems, in order to reduce the connection lines between photovoltaic modules and inverters, facilitate maintenance, and improve reliability, it is generally necessary to add a combiner device between the photovoltaic modules and inverters. Our company’s combiner box series products are specially designed to meet this requirement and are used in large-scale photovoltaic grid connected power generation systems. They are placed in front of the photovoltaic modules and inverters to reduce the length between them, facilitate system maintenance, and improve reliability. The photovoltaic array combiner cabinet can connect a certain number of photovoltaic modules with the same specifications in series to form one photovoltaic module string according to the DC voltage range input by the inverter, and then connect several strings to the photovoltaic Rixuan Rirui lightning protection combiner box. The output is after the Ningchoucun lightning protection device and circuit breaker, which facilitates the connection of the subsequent inverter.

Product Features

• The cabinet body is generally made of steel plate spray coating, stainless steel, engineering plastic, etc. It has a beautiful and generous appearance, is sturdy and durable, easy to install, and has a protection level of IP 54 or above.
• It is waterproof and dustproof, meeting the requirements for long-term outdoor use. At the same time, it can be connected to multiple photovoltaic arrays and equipped with insurance components (replaceable with other grades).
• Equipped with photovoltaic dedicated high-voltage lightning arrester, both positive and negative poles have lightning protection function.
• Adoptd with a four pole circuit breaker with positive and negative poles connected in series to improve the DC withstand voltage.
