Description

Growatt SEM-E 50kW Energy Management System is the central control unit for larger photovoltaic systems with multiple inverters. The Smart Energy Manager manages up to 10 solar and storage inverters, ensures reliable feed-in limitation, and provides you with seamless online monitoring across the entire system.

Key Benefits for Your System

Centralized management: Control and monitor up to 10 solar and storage inverters from a single device.
Secure feed-in limitation: The Growatt SEM-E regulates grid feed-in for the entire system and reliably complies with legal requirements.
Flexible communication: RS485 (up to 500 m) and Ethernet (up to 100 m) enable customizable integration into your project.
Rugged design: With IP65 protection and an operating temperature range of −25 °C to +60 °C, the system is also suitable for demanding locations.

Intelligent Management of Your Solar Power

With the Growatt SEM-E energy management system, you keep an overview of your entire photovoltaic system. The device captures the relevant measurements via flexible current transformers (CTs) and automatically adjusts the feed-in of solar power to the grid operator's requirements. This helps you avoid unwanted back-feeding while maximizing your self-consumption. Thanks to online monitoring, you can keep track of yields and consumption at any time and operate your system efficiently. The system is suitable for projects with multiple inverters and integrates seamlessly into your existing infrastructure as a central control point.
