Single Phase Meter

The AlphaESS SM50A single-phase meter is a digital electricity meter designed for integration with AlphaESS energy storage systems, such as the SMILE series. While there is no official "SM50A" model listed in AlphaESS documentation, the naming convention and similar products (like the Acrel SM60A) suggest it is a compact, high-precision, single-phase meter for monitoring energy flow in residential solar and storage applications.

Key Features:

• Single-phase measurement: Designed for 230 V AC networks, suitable for residential installations.

• Current rating: Typically up to 50 A, direct connection (some similar meters support 60 A).

• High precision: Accurate measurement of energy consumption and export.

• LCD: Provides clear real-time readings of voltage, current, energy, and other electrical parameters.

• Bi-directional metering: Measures both imported and exported (solar/self-consumption) energy.

• Communication: RS-485 (Modbus) interface for seamless integration with AlphaESS energy management systems.

• Easy installation: Compact design for DIN rail mounting.

• Applications: Used for monitoring and managing energy flow in homes with AlphaESS storage and solar PV systems.

Typical Use:
Monitors energy import/export, supports smart energy management, and enables accurate billing or self-consumption tracking in AlphaESS-powered homes.
