Description

Acrel ADL400 Smart Meter for Solis – Three-Phase is a precise energy metering device for your PV system with a Solis inverter. It records all relevant electrical parameters in the three-phase grid with an accuracy class of 0.5, enabling reliable monitoring of self-consumption and grid feed-in. Connection is available either directly up to 80 A or via external current transformers (CT) with 6 A.

Key Benefits for Your System

High measurement accuracy: Active energy is recorded with accuracy class 0.5, and electrical parameters with an error tolerance of only ±0.2 %.
Flexible connection: Choose between direct connection up to 80 A or measurement via external current transformers with 6 A.
Easy integration: The RS485 interface with Modbus-RTU protocol reliably connects the smart meter to your Solis inverter.
Compact DIN rail mounting: The slim housing can be installed on the DIN rail to save space.

Intelligent Control of Your Solar Power

For your Solis inverter to optimally regulate self-consumption, it requires precise measurement data on grid draw and feed-in. This is exactly the task performed by the Acrel ADL400 smart meter at the grid connection point. It continuously measures voltage, current, active, reactive, and apparent power, as well as the power factor on all three phases. The recorded values are transmitted to the inverter via RS485, allowing zero feed-in or targeted self-consumption to be precisely controlled. This way, you make optimal use of your self-generated PV power, reduce your electricity costs, and gain greater independence from the public grid. Thanks to the simple DIN rail installation and proven Modbus communication, the smart meter integrates easily into your existing system.
