Fronius Smart Meter WR100-600V

The Fronius 4300013591 Smart Meter WR100-600V is a bidirectional energy monitoring device for tracking production and consumption in residential and commercial PV systems. Rated for 120 – 600 V nominal voltage across 1PN, 2P, 2PN, 3P and 3PN grid types, it supports current transformers from 1 to 6,000 A and achieves ANSI C12.20 Class 0.5 accuracy. It communicates with Fronius inverters over Modbus RTU (RS485) for accurate self-consumption optimization.

Key Features:

• Nominal voltage 120 – 600 V, 45 – 65 Hz
• Accuracy Class 0.5 (ANSI C12.20 / C12.1)
• CT primary 1 – 6,000 A, 333 mV secondary
• Maximum current 3 x 6,000 A
• Grid types 1PN, 2P, 2PN, 3P, 3PN
• Modbus RTU (RS485) inverter interface
• Self-consumption 1.75 W, starting current 40 mA
• Wall mount, IP40, -40°F to 176°F
• Wire cross section up to 2.5 mm²
• 153 x 85.1 x 38.0 mm, 0.5 lbs, 5-year warranty

Ideal for residential and commercial solar installations requiring precise energy metering and self-consumption optimization. It suits multi-phase systems using external current transformers and integrates directly with compatible Fronius inverters via RS485, and can be mounted outdoors inside a NEMA 3R/4 or IP66 enclosure.
