Huawei Smart PS-100A single-phase meter 100A

Huawei SmartPS-100A-S0 – Single-phase 100A smart meter module

The Huawei SmartPS-100A-S0 is a single-phase, Class 1 accuracy smart meter designed for use with Huawei hybrid invertersfor real-time energy consumption measurement. It can be mounted on a DIN35 rail, features a built-in LCD display, and communicates with the inverter via the RS485/Modbus-RTU protocol—this forms the basis for precise zero-export control and efficient energy management.

Class 1 measurement accuracy on single-phase networks

The SmartPS-100A-S0 operates in a single-phase (1P2W) network with a measurement range of 0–100A and a voltage range of 176–288V AC. Measurement accuracy: voltage and current ±0.5%, power and energy ±1%, frequency ±0.01 Hz. The measured values can be easily read on the LCD display, and settings can also be adjusted directly on the device.

Installation and Communication

The module can be mounted on a DIN35 rail; its dimensions are 100×36×65.5 mm, and its power consumption is only ≤0.8W. It communicates via an RS485 interface using the 9600 bps Modbus-RTU protocol. The package includes 1 CT 100A/40mA (5m) and an RS485 cable (10m), so all the accessories needed for commissioning are included. It is compatible with Huawei’sentire ecosystem of communication accessories.

When should you choose the SmartPS-100A-S0?

This module is ideal for single-phase systems—such as smaller residential solar installations where the inverter is also single-phase. If you are considering a three-phase system, the Huawei YDS60-80 three-phase metering moduleis the recommended choice. Due to its simplicity and compact size, the SmartPS-100A-S0 is one of the most commonly used metering devices in single-phase Huawei systems.

SOLARKIT Reviews

The Huawei SmartPS-100A-S0 is one of the best examples of reliable and easy-to-install single-phase metering modules. Class 1 accuracy, an LCD display, and all necessary accessories included in the box—a plug-and-play solution. We recommend it to those looking for precise consumption measurement and zero-export control to complement theirsingle-phase Huawei inverter.
