COMBINER BOX MONITORING SYSTEM
With real-time monitoring of the current, voltage, temperature, and switch status of the combiner box string, as well as remote data transfer using wired or wireless techniques, this device is intended for 1500V/1700V solar power systems.
DC arc detection integrated into the combination box for installation
PV system at 1500/1700V
Data transfer, histogram current, voltage, temperature, and electrical energy science presentation, decoration operation, and renovation effectiveness using RS485 and Power Line Communication (PLC)
Support computerized fact freezing, handle allocation, and log recording
Instead of tripping the power supply, the shunt time out unit can be pushed simultaneously, saving money. Support electrical line communication (PLC)mode; RS485 wiring is not an option
