Device Overview
Acrel ACR10R-D16TE is a rail-mounted multifunction energy meter for single-phase AC monitoring. It is especially useful where a PV inverter, grid-connected cabinet, or energy-management panel needs a compact meter with a split-core CT and local RS485 Modbus RTU data.
Core Features
The meter measures voltage, current, active power, reactive power, apparent power, frequency, power factor, active energy, and reactive energy. Acrel's official product page lists 120 A maximum current for this D16TE configuration and measurement precision of active energy 0.5 level and reactive energy 1 level.
Installation And Current Sensing
ACR10R-D16TE mounts on DIN35 rail and uses an external split-core current transformer with a 16 mm through size. This makes it better suited to retrofit PV and distribution-cabinet work than a meter that requires busbar removal.
Connectivity And Integrations
The official source lists RS485 interface with Modbus RTU. That makes the meter suitable for local SCADA, EMS, gateway, inverter, or automation polling. Home Assistant support is treated as standards-based Modbus integration through a compatible RS485 adapter or gateway, not as an Acrel-native plug-and-play integration.
Solar And Import/Export Fit
The product is positioned by Acrel for PV inverter and grid-connected cabinet monitoring. Because the meter supports positive/negative and active/reactive energy measurement, it is a good fit for installations that need import/export or anti-reflux visibility at the correct single-phase measurement point.
Buying And Source Notes
Use the official Acrel product page for current specifications, images, manual access, and quote/contact routing. Local availability, inverter bundles, certification fit, and CT variant details should be confirmed before specifying it for a project.
