Photovoltaic Combiner Box Monitor, is specially applied to intelligence PV junction box for monitoring the operating status of the PV cells, measuring the current and voltage of the PV cells, collecting status of Surge protection Device (SPD) and DC breaker. Current measurement uses Hall Effect to collect data, which are isolated collection and threaded installation to increase reliability of junction box. This device can not only displays measured and collected data and status of device, but also can connects industrial equipments and computers through RS485 interface to constitute a measurement and control system.
Features
- 1 serial communication interface, interface mode RS485, 2500V photoelectric isolation + lightning protection;
- Sampling and processing 0 ~ 16 channels of photovoltaic panel current (0 ~ 15A), accuracy 1%;
- Installed in the outdoor wall-mounted combiner box to adapt to harsh environmental conditions;
- Convenient to modify the communication address, which can be modified by key operation locally;
- With CE certification;
- Using photovoltaic self-powered power supply (210-1500VDC), the power module protection level reaches IP30;
- The current acquisition unit uses a self-developed sensor module, which greatly improves the reliability;
- 8-channel, 12-channel, 16-channel, current collection unit is integrated (non-splicing method, improve reliability);
- Protection grade IP30, can effectively protect the internal PCB board for a long time;
- Local digital display is required to display current, voltage, communication parameters, etc .;
- Adopt vertical installation method to save the space of the combiner box;
- Monitor the status of the lightning arrester and the output circuit breaker;
