Sigenergy Sigen Sensor Single Phase-DH

Overview

Sigenergy Sigen Sensor Single Phase-DH: DIN-rail 100 A meter with built-in CT, 1 % power accuracy, 100 ms refresh and Modbus RTU over RS485. Auto-pairs with Sigenergy inverters; optional Wi-Fi HaLow kit extends data to 200 m for seamless smart-energy control.

Description

The Sigenergy Sigen Sensor Single Phase-DH is a DIN-rail power-measurement module that gives installers 1 %-accurate import-export data without extra wiring or complex commissioning. Designed to pair instantly with SigenStor batteries and Sigen inverters, it feeds real-time values to the mySigen app every 100 ms, enabling rapid battery response, tariff optimisation and grid-code compliance.
Key benefits for installers
Plug-and-monitor integration – the sensor identifies itself on the RS485 bus; no manual setup when connected to Sigenergy devices.
High precision – built-in 100 A current transformer and 0.5 % voltage/current accuracy deliver Class 1 power readings for billing-grade control.
Fast refresh – 100 ms update interval allows sub-second battery dispatch for frequency-support or peak-shaving modes.
Compact DIN form factor – just 36 mm wide, 100 mm high; mounts on any 35 mm rail inside the consumer unit.
Wi-Fi HaLow ready – add the optional Sub1G kit to transmit data up to 200 m through walls at 868 MHz, ideal for outbuildings or thick masonry.*

Use-case highlights
Dynamic import/export control – precise kW data lets SigenStor hold grid export at predefined limits or follow zero-export mandates.
Tariff-aware battery scheduling – 100 ms metering synchronises charge/discharge with half-hourly price signals for maximum savings.
Fleet O&M – granular sensor data flows to Sigenergy Cloud, supporting remote diagnostics and performance guarantees.
Installation workflow
Clip the Sigenergy Sigen Sensor Single Phase-DH onto a spare DIN rail slot next to the main breaker.
Pass the live conductor through the integrated 16 mm aperture and tighten terminals.
Daisy-chain RS485 to the inverter, power up, and verify readings on the LCD and mySigen app.
For retrofit or new-build projects where space, speed and accuracy matter, the Sigenergy Sigen Sensor Single Phase-DH delivers utility-grade measurement that unlocks the full potential of smart PV-battery systems.
