[Pre-order] Sunpura Dual-Channel Smart Meter, 6CT

Sunpura Dual-Channel Smart Meter (SMeter-RS076)

Intelligent Energy Management. Precise Measurement. Future-Proof.

The Sunpura Dual-Channel Smart Meter SMeter-RS076 is a high-precision measuring device for modern households that reliably records the generation data of third-party inverters and integrates it into your existing PV or storage system. As a core accessory in the Sunpura ecosystem, it provides you with real-time insights into energy flows – for better decisions, higher self-sufficiency, and optimized costs.

✅ Key Features

• Dual-Channel CT Measurement: Two CT inputs for simultaneous recording of two independent circuits – ideal for third-party inverters and separate loads.
• High-Precision Measurement: RMS measurement for 3-phase systems (3P, 3P+N) including harmonics for complete and reliable data.
• Flexible Communication: Wi-Fi (2.4 GHz & 5 GHz), optional LoRa as well as RS485 – for cloud and edge applications.
• Real-Time Updates: Data updates up to 500 ms – energy flows visible almost in real-time.
• Compact & Robust: DIN rail mounting, small design – suitable for standard distribution boxes.

⚠️ Safety & Installation (Important)

• Installation only by qualified personnel: Work on high-voltage current exclusively by qualified electricians.
• Observe CT direction: Arrow direction (P1 → P2) must follow the current flow from the grid to the load, otherwise measurement errors will occur.
• Switch off power before work: Always turn off the main switch and check for absence of voltage.
• WLAN Stability: For weak signals, we recommend a repeater/powerline near the meter cabinet.
