COMBINER BOX MONITORING SYSTEM
1500V/1700V
Designed for 1500V/1700V solar power system, Real-time monitoring of the current, voltage, temperature, and switch status of the combiner box string, data abnormal alarm output, support for wired or wireless data remote transmission.
Combiner box for installation,Integrated DC arc detection
1500/1700V PV system
Histogram current, voltage, temperature，power generation display, improve operation and maintenance efficiency RS485 and Power Line Communication (PLC) for data transmission
Supports current arc detection, alarm threshold can be set, automatic tripping and remote tripping can be realized
Support automatic address allocation, data freeze, log record
Shunt trip unit can be driven directly without tripping power supply, saving cost Support power line communication（PLC）mode, no need for RS485 wiring
