24strings Solar PV System Combiner Box Monitoring

Availability:

BRIEF INTRODUCTION

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.

INSTALLATION METHOD

DC arc detection built-in into the mixture field for installation

ADVANTAGE

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

NEW FEATURES

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
