Solis Single-Phase Meter DDSD1352-INL for Grid-Tied Inverters

The Solis single-phase meter (Acrel DDSD1352-INL) is used to limit the export capacity of PV systems connected to Solis grid-tied inverters with meter port. The meter monitors grid and load power flow to enforce export power limitations, ensuring compliance with local grid regulations.

Rated for 220V single-phase (1P+N) operation with a maximum input current of 10(60)A. The meter features voltage accuracy ±0.2%, current accuracy ±0.2%, and power accuracy ±0.5%, with Active Energy Class 1 and Reactive Energy Class 2 ratings. Compatible with Solis inverter models including S6-GR1P(0.7-3.6)K-M, S6-GR1P(2.5-6)K, S6-GR1P(8-10)K, Solis-mini-(0.7-3.6)K-4G, and Solis-1P(2.5-6)K-4G.

The meter is preset for direct site installation with no parameter changes required. It comes with two connection terminals—one for the grid side and one for the inverter/load side—and operates reliably between −25°C and +55°C in non-condensing environments up to 95% relative humidity.
