The SGE intelligent photovoltaic DC combiner box monitoring device is applied to the intelligent photovoltaic combiner box, which has the functions of monitoring the operation status of the solar panels in the photovoltaic array, measuring the current and voltage of the photovoltaic cells, collecting the status of surge protectors in the combiner box, collecting the status of DC circuit breakers, and outputting relay contacts to drive external actuators.
The intelligent photovoltaic DC combiner box monitoring device can display real-time data and status of each circuit in the combiner box, and can be connected to industrial control equipment and computers through RS485 interface to form a smart photovoltaic operation and maintenance measurement and control system.
Installed inside the hanging combiner box on the outer wall of the room, suitable for harsh environmental conditions.
It is convenient to modify the communication address by pressing the buttons on the product.
Adopting photovoltaic power supply (210-1500VDC) power module, with a protection level of IP30.
The current acquisition unit uses independently developed sensor modules.
The current acquisition unit adopts an integrated structure, non splicing method, to improve reliability.
The protection level of the product shell reaches IP30, which can provide long-term effective protection for the internal PCB board.
There is a local LCD screen display that shows current, voltage, temperature, etc.
One serial communication interface, interface mode RS485, 500V is optoelectronic isolation+lightning protection.
Sample and process 1-24 channels of photovoltaic panel current (0-20A) with an accuracy of 1%.
Adopting an upright installation method to save space in the combiner box.
