Overview

Solis S3-Logger is a high-performance system data logger and energy management controller engineered for commercial (C&I) and industrial photovoltaic plants. It is available as the standard S3-Logger and as the S3-Logger-EPM with extended export power control functions.

The device supports group connection of up to 80 Solis inverters over an RS485 bus (Modbus RTU/TCP) and guarantees uninterrupted data transfer to the SolisCloud platform via Ethernet (LAN), 4G or Wi-Fi. The EPM version enables effective real-time export limiting (Zero Export), reacting to changes in site load within fractions of a second.

The S3-Logger supports open industrial protocols (SunSpec, Modbus), making it easy to integrate into external SCADA supervisory systems and energy management systems (EMS). The logger is housed in a rugged enclosure for DIN-rail or wall mounting, offers ample internal memory for log storage and supports over-the-air (OTA) firmware updates for every connected inverter.
