Sofar Smart Meter DTSU666 3-phase 5(80)A (901.00000058-0)

The three-phase meter/Smart Meter Chint DTSU666 in the version 5(80)A (SOFARSOLAR accessory code: 901.00000058-0) is designed for direct connection to installations up to 80 A. It allows integration of energy measurement in SOFARSOLAR 3-phase storage systems and inverters (e.g. HYD 3PH, ME 5-20KTL-3PH) without the need for external current transformers for currents up to 80 A.

Manufacturer and compliance: The meter is model Chint DTSU666, listed in SOFARSOLAR documentation as a Smart Meter for use with 3-phase inverters. Version 901.00000058-0 is a variant allowing direct current connection up to 80 A and is recommended in SOFARSOLAR's documentation for HYD 3PH inverters.

Electrical parameters

• Model: Chint DTSU666 (3-phase version)
• Current range (direct connection): 5(80) A (direct connection up to 80 A)
• Nominal voltage: 3 x 230/400 V (according to the description of the 3-phase DTSU666 version in the documentation)
• Function: three-phase smart energy meter for integration with SOFARSOLAR inverters
• Communication: (version listed as Smart Meter for HYD 3PH; the document contains communication variants for the DTSU666 series, however, the specific communication interface for code 901.00000058-0 is not extensively described in the document)

Mechanical parameters

• Mounting type: version for direct series connection (mounting on a rail or in a distribution board depending on the installation) — according to the application of the three-phase meter
• Compatibility with inverters: recommended for HYD 3PH and ME 5-20KTL-3PH (in SOFARSOLAR documentation as an accessory for these models)
• Catalogue designation: 901.00000058-0
• Installation notes: does not require external transformers for direct connection up to 80 A; for higher current installations, an external CT is used (e.g. LCTA9CC 200A/100mA)
