Waterproof 10A Solar PV Combiner Box 1000V DC For Big S
Waterproof 10A Solar PV Combiner Box 1000V DC For Big Solar Power Station
10 strings(10 inputs) Intelligent PV array combiner boxes with monitoring device for big solar power station
Quick Detail:
10 strings Intelligent PV array combiner boxes with monitoring device for big solar power station.The combiner box is a device that combines the output of multiple strings of PV modules for connection to the inverter. It is typically used in the larger commercial and utility scale PV power plants. The combiner box commonly houses the input over current protection fuse assemblies for several strings (from as few as 2 strings to as many as 32), as well as the combined bus of those inputs into a single main output.
The PV combiner box also house other components for the site, such as a DC disconnect, surge protective devices and string monitoring hardware.
Description:
SCB-Monitoring Device SCBM4A,SCBM8A, SCBM12A ,SCBM16A is specially applied to intelligent PV combiner box. It can monitor the operating status of the solar , measure the current and voltage of solar panels, collect the SPD (Surge Protective Device) status and the DC breaker status and control relay output for driving external executive body. The device can display the measured data and the status of the other device via 6 digital screen. It can also connect the industrial equipment and computer to compose the monitoring via the RS485 interface.
Intelligent PV combiner monitoring terminal unit is based on the Modbus-RTU communication protocol. The checksum and the data sequence which are defined by Modbus protocol are necessary for the specific data exchange. The Modbus protocol is used in a communication line which the host requested and the slave respond. That is a half duplex means of communication. First of all, the host computer sends signal to a unique slave terminal according to the address, and then the slave device response the signal to the host computer.
In a large photovoltaic (PV) grid generation , it is generally to install a DC combining device between the PV module and inverter in order to reduce the connection between PV module and inverter, facilitate maintenance and improve reliability. Our intelligent photovoltaic combiner box with SPD series are especially designed to meet the requirement, which can provide a solution for PV power generation matching with photovoltaic inverter. According to the input voltage of the inverter, a fixed number of similar PV modules can be connected to form a PV array by using PV array combiner box. Then different channels of PV arrays can be combined into the PV combiner box. Its output can be connected to inverter by way of circuit breakers with SPD protection.
