COMBINER BOX MONITORING SYSTEM
This system is designed for 1500V/1700V photo voltaic energy systems, with real-time monitoring of the current, voltage, temperature, and change repute of the combiner field string, and faraway statistics transmission through wired or wi-fi methods.
DC arc detection built-in into the mixture field for installation
1500/1700V PV system
RS485 and Power Line Communication (PLC) for data transmission, histogram current, voltage, temperature, and electrical energy science display, decorate operation and renovation effectivity
Support computerized handle allocation, facts freeze, log record
Shunt time out unit can be pushed at once besides tripping strength supply, saving cost Support electricity line communication（PLC）mode, no choose for RS485 wiring
