SDM230-Lora P2P is a smart single-phase energy meter that adopts Point-to-Point (P2P) LoRa wireless communication technology. The meter measures and displays the characteristics of single-phase two-wire (1P2W)

systems, including voltage, frequency, current, power, active energy, and reactive energy (imported or exported). Energy is measured in kWh and kvarh. Maximum demand current can be measured over preset periods of up to 60 minutes.

This product consists of two parts: the SDM230-Lora meter and the ES-LR1 receiver module. The meter supports direct connection up to 100A without external current transformers (CTs). Through LoRa point-to-point communication, the meter connects directly with the receiver module, enabling remote data collection without the need for gateways or network servers.

SDM230-Lora P2P is a single-phase multi-function energy meter suitable for scenarios such as residential complexes, commercial buildings, industrial facilities, and IoT-based energy management platforms.
