Growatt smart energy manager SEM-E 50 kW

The Smart Energy Manager (sme-e 50kW) from Growatt was designed for the intelligent monitoring of self-consumption and limiting the export of solar and storage systems. It also has the ability to provide flexible current transformers (CTs) for different system sizes with high control accuracy. Its failsafe function also ensures the safety and reliability of the system.

Features

• Intelligent management
• 24-hour monitoring of self-consumption
• Online monitoring
• Feed-in limits
• Fail-safe and high control accuracy
• Flexible CTs for different project sizes
• Can be used for 380v and 480v three-phase grids
• Max. Number of inverters: 10
• RS485 and Ethernet connection

Components of the Smart Energy Manager

• ShineMaster: Is the control core and serves as data communication with the inverter and the electricity meter. It implements the inverter power control function and remote monitoring.
• Electricity meter: It displays the voltage, current and function parameters in real-time monitoring.
• Power supply: Supply for the ShineMaster.
• Circuit breaker: Controls the start and shutdown of the electricity meter and power supply.
• Connection terminal: This is where the wiring is done.

The Smart Energy Manager supports both grid-connected and hybrid/AC-coupled inverters and works as follows: The inverter converts the direct current generated by the sun into alternating current in the photovoltaic string. The energy generated by the inverter can be used for the user load, battery charging or feeding into the grid. The smart energy manager is located between the inverter, the user load and the grid and records the voltage and current of the grid connection point. Depending on the user's needs and settings, the output power of the inverter is adjusted in real time to control the final feed-in to the grid.
