Combination box monitoring system
The current, voltage, temperature, and switch status of the combiner box string are all continuously monitored by this device, which is made for 1500V/1700V solar power systems. It also allows for remote data transfer via wired or wireless means.
For installation, a DC arc detector is built into the combo box.
PV needs 1500/1700 volts.
Utilizing RS485 and Power Line Communication, data transfer, histogram current, voltage, temperature, and electrical energy science display, decoration operation, and renovation effectiveness (PLC)
The preservation of logs, fact freezing, and automated handle allocation are all supported.
To save money, it is possible to simultaneously push the shunt time out unit rather than trip the power supply. Support electrical line communication in the (PLC)mode; RS485 wiring is not an option. RECENT OPTIONS
