monitoring system for combination boxes
This device, designed for 1500V/1700V solar power systems, continuously monitors the current, voltage, temperature, and switch state of the combiner box string. Additionally, it supports wireless or wired remote data transfer
A DC arc detector is included into the combo box for installation.
PV demands 1500–1700 volts.
Data transfer, histogram current, voltage, temperature, and electrical energy science display using RS485 and Power Line Communication, decoration operation, and renovation effectiveness (PLC)
There is support for automated handle allocation, fact freezing, and log retention.
Instead of tripping the power supply, it is possible to concurrently push the shunt time out unit to save money. Support RS485 wiring in the (PLC)mode; electrical line wiring is not an option. MODERN OPTIONS
