Model: FR-DCMG series
Manufacturer: Fonrich
Description: INTELLIGENT COMBINER BOX MONITORING MODULE
1000V~1700V Combiner Box Monitoring
A Gilgal 3 combiner box monitoring system supports 1000V/1700V PV systems, real-time monitoring of the string current, bus voltage, bus box temperature, switch status, and alarm output when abnormal data is obtained. The system supports RS485 or industrial wireless data transmission for data transmission.
Features:
– Supports up to 32 channels
– Local LED display, real-time display of photovoltaic string information
– You can view the total power generation of each string
– RS485 or PLC communication
– Various specifications of Hall sensors, ±20A, ±30A, ±40A, ±60A
– Optional: Support shunt release
