Device Overview
The Acrel ADL100-ET is a compact single-phase DIN-rail energy meter for low-voltage circuits. It is useful where a panel, sub-circuit, small commercial board, equipment feed, or energy-management cabinet needs local kWh metering plus electrical-parameter visibility without relying on a vendor cloud service.
This record is scoped strictly as an energy meter. It is not a solar inverter, battery-storage device, EV charger, or gateway/data-logger-only product.
Core Characteristics
Acrel's official product page lists the ADL100-ET as a single-phase 2P DIN-rail power meter with 10(60) A current, AC220/230 V voltage context, Class 1 accuracy, and measurement of voltage, current, active power, reactive power, apparent power, power factor, and frequency. The official manual also documents single-phase active kWh measurement, positive and negative active energy, pulse output, infrared communication, and optional RS485 Modbus RTU communication.
Installation And Metering Fit
The ADL100-ET is a direct-connected single-phase meter for 10 A basic current and 60 A maximum current. That makes it different from CT-operated monitors: the circuit conductor is wired through the meter terminals, so installation should be handled inside suitable electrical equipment by a qualified installer. It is best treated as a compact DIN-rail sub-meter or circuit meter rather than a clamp-on whole-home monitor.
The 60 A direct-current rating matters for comparison because it defines the circuit size this exact page can safely describe. Higher-current applications should use a suitable CT-operated meter or another model rather than assuming ADL100-ET can scale beyond the documented 10(60) A configuration.
Communication And Integrations
For the /C communication variant, Acrel documents RS485 with Modbus RTU. That supports local polling by a gateway, PLC, SCADA system, energy-management platform, or other Modbus-capable controller. Home Assistant support is therefore treated as standards-based through Home Assistant's generic Modbus integration and compatible RS485 hardware, not as an Acrel-native Home Assistant integration.
Because the meter provides local metering and optional RS485 Modbus RTU, no vendor cloud is required for the core measurement data path.
Solar And Import/Export Context
The manual documents positive and negative active-energy measurement. That makes the meter relevant for import/export visibility when installed at an appropriate point in a solar or sub-metering system. It should not be confused with an inverter, export controller, or solar monitoring platform by itself.
Strengths And Limits
ADL100-ET is strongest when the buyer needs a compact DIN-rail single-phase meter with direct 60 A metering, LCD display, pulse output, and optional Modbus RTU. It is less suitable for app-first homeowners, multi-channel circuit monitoring, high-current feeders, or installations that need an out-of-the-box cloud dashboard.
Purchase And Source Notes
Acrel's official product page provides the current product details, product images, PDF download route, and Get A Quote path. No direct public checkout price was verified during the 2026-07-22 CST review, so pricing and availability should be confirmed through Acrel or local distributors before procurement.
