Description

Product Description

• Central communications hub that connects multiple Sungrow inverters and related equipment to a monitoring system and cloud platform for system supervision and management.

• Supports batch parameter settings and firmware updates for connected inverters to streamline operations and reduce onsite maintenance effort.

• Provides flexible networking with support for RS485, Ethernet, and WLAN (Wi-Fi) connections — enabling communication with energy meters, environmental sensors, and weather stations.

• Local server built into the device allows configuration and real-time monitoring of the PV plant and connected peripherals.

• Rugged, weather-resistant enclosure suitable for outdoor or indoor installation, with integrated night maintenance light to assist service personnel in low-light conditions.

• Optimises operational expenditure by enabling remote web access for plant maintenance and monitoring, reducing the need for frequent site visits.
