12v 24v 48v Solar Street Light Battery Underground Box Battery Waterproof Box

Description:

In large and medium-sized photovoltaic grid-connected power generation systems, in order to facilitate maintenance and repair and improve the reliability of system operation, it is generally necessary to add a DC bus device between the photovoltaic module and the inverter. The company's photovoltaic array lightning protection junction box series products are designed to meet this requirement. The use of photovoltaic junction box can greatly reduce the wiring between photovoltaic modules and inverters. Users can connect a certain number of photovoltaic modules with the same specifications in series to form a series of photovoltaic modules according to the range of DC voltage input by the inverter used, and then connect several series to the photovoltaic array lightning protection junction box for confluence The output after the lightning device and the circuit breaker facilitates the access of the subsequent inverter.

Application

In the photovoltaic power generation system, a large number of photovoltaic cell modules are connected in series and parallel to achieve the required voltage and current values, so as to optimize the power generation efficiency. The main function of the intelligent photovoltaic combiner box is to perform a primary merger on the input of the photovoltaic cell array, which is used to reduce the connection of the photovoltaic cell array to the inverter, optimize the system structure, and improve reliability and maintainability. While providing the confluence lightning protection function, it also monitors the operation status of the photovoltaic panel, the current, voltage, power, lightning arrester status, DC circuit breaker status collection, relay contact output and other functions after confluence, with wind speed, temperature, radiation The sensor interface functions such as the light meter are available for customers to choose. The device is equipped with an RS485 interface as standard, which can upload the measured and collected data to the monitoring system.
