Description

Solis Meter-1P-Acrel (Acrel DDSD1352) is a single-phase energy meter for precise measurement of active energy consumption in the low-voltage grid, and works together with your Solis inverter to reliably record your solar power data. With an accuracy class of 1 and an integrated RS485 interface, this meter is particularly well suited for monitoring and self-consumption control of your photovoltaic system.

Key Benefits for Your System

Precise measurement: The meter records your consumption with accuracy class 1 in accordance with IEC62053-21 and IEC62053-22.
Comprehensive data acquisition: In addition to active energy, voltage, current, active, reactive and apparent power, power factor, and frequency are also measured.
Easy communication: Via the RS485 interface with Modbus RTU protocol, you can easily integrate the meter into your Solis system.
Space-saving mounting: The compact DIN rail housing can be installed quickly in your distribution board with minimal tools.

Smart Monitoring of Your Solar Power

A reliable energy meter is the foundation for transparent energy management of your photovoltaic system. The Solis Meter-1P-Acrel supplies your inverter with the measurement data needed to precisely distinguish between self-consumption, feed-in, and grid draw. This way, you always have an overview of how much solar power you use yourself and how much flows into the grid. The values can be conveniently read out via the RS485 interface and transferred to your monitoring system. All relevant electrical parameters are displayed directly on-site via the integrated LCD display. This gives you a solid foundation for greater independence, an optimized self-consumption rate, and a noticeable reduction in your electricity costs. Connection is made via direct measurement, and correct input/output direction must be observed.
