Monitoring system for combination boxes
This device is designed for 1500V/1700V solar power systems and features real-time monitoring of the current, voltage, temperature, and switch status of the combiner box string, as well as remote data transfer utilizing wired or wireless methods.
For installation, DC arc detection is built within the combination box.
PV at 1500/1700 volts
Utilizing RS485 and Power Line Communication, data transfer, histogram current, voltage, temperature, and electrical energy science display, decoration operation, and renovation effectiveness (PLC)
Support automated handle allocation, fact freezing, and log keeping
The shunt time out unit can be pushed concurrently to save money rather than trip the power supply. Support the (PLC)mode of electrical line communication; RS485 wiring is not an option NEW OPTIONS
