Acrel DTSD1352-C Solar Inverter Smart Meter
General
Acrel Sungrow/Solis smart meter DTSD1352 din rail type multi-function energy meter is an intelligent instrument designed mainly for energy statistics and management needs of power systems, industrial and mining enterprises, and public facilities. Integrate common power parameter measurement and power metering and assessment management, and provide various power data statistics for the past 48 months. DTSD1352 has 2~31 times sub-harmonic and total harmonic content detection, with switch input and switch output, it can realize "remote signal" and "remote control" functions, and has alarm output.
DTSD1352-C Solar inverter smart meter is designed for PV solar system, which already have configured with several inverter like Sungrow, Solis etc. It can be directly used together with these inverter through RS485 communication. realize the measure and monitor function.

DTSD1352-C Solar Inverter Smart Meter FAQs
Yes, press the key to set the meter to three-phase three-wire mode.
Ordinary secondary meter could access the ratio XXX/5(1)A of the CTs which could be actual current on-site, the -CT model comes with an external transformer will be convenient for installation(It cannot be disassembled, otherwise it will burn the meter). There are CTs available on site to facilitate with No stitch removal.
3*100V, 3*57.7/100V are used for high voltage, used in conjunction with voltage transformers, where 3*100V represents 3P3W,3*57.7V/100V represents 3P4W; 3*380V, 3*220V/380V are used for low voltage, direct voltage input, among them3*380V represents 3P3W, 3*220V/380V represents 3P4W.
Yes, only need PLC to support RS485 interface, Modbus RTU, or DL/T645 protocol.
