high voltage Automatic Control Protection Combiner Box Monitoring

Availability:

BRIEF INTRODUCTION

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.

INSTALLATION METHOD

DC arc detector is integrated inside the combination box for installation.

ADVANTAGE

1500/1700 volts for PV



Data transfer, histogram current, voltage, temperature, and electrical energy science presentation, decoration operation, and renovation effectiveness using RS485 and Power Line Communication (PLC)

NEW FEATURES

Automated handle allocation, fact freezing, and log maintenance are supported.



Instead of tripping the power supply, the shunt time out unit can be pushed concurrently to save money. Support electrical line communication in the (PLC)mode; RS485 wiring is not an option. RECENT OPTIONS
