Sofar Solar ESI DDSU666 single-phase smart meter

Smart Meter Single Phase Sofar Solar ESI DDSU666

The Sofar Solar ESI DDSU666 single-phase Smart Meter is a new-generation smart meter specially designed for Sofar Solar ESI hybrid inverters. This bi-directional meter allows you to monitor your solar production, electricity consumption and self-consumption rate in real time via the SolarMan Smart mobile application.

Compatible with the Sofar Solar ESI PowerAll range

This meter is specifically designed for Sofar Solar ESI hybrid inverters, the PowerAll range renowned for its reliability and exceptional performance. It integrates perfectly with all ESI single-phase models:

• Sofar ESI 3K-S1 (3 kVA) - Compact residential installations
• Sofar ESI 3.68K-S1 (3.68 kVA) - Optimised format for small homes
• Sofar ESI 4.6K-S1 (4.6 kVA) - Ideal intermediate power
• Sofar ESI 5K-S1-A (5 kVA) - Synergrid version for large homes
• Sofar ESI 6K-S1 (6 kVA) - High power installations

Guaranteed compatibility: This equipment is certified compatible with Sofar Solar ESI single-phase inverters, guaranteeing optimum performance and easy integration into your photovoltaic system with battery.

Real-time monitoring via SolarMan Smart

The DDSU666 meter communicates directly with your Sofar ESI inverter, which then transmits the data to the SolarMan Smart application. This monitoring platform offers you :

• Instant solar production: Track the energy generated by your panels live.
• Real-time consumption: View your total electricity consumption
• Self-consumption rate: Calculated automatically to optimise your savings
• Grid export/import: Monitor the energy injected or withdrawn from the grid
• Detailed historical data: Daily, weekly, monthly and annual graphs
• Smart alerts: Notifications in the event of anomalies or reduced production

High-precision bidirectional measurement

The DDSU666 meter uses advanced measurement technology to guarantee professional accuracy for all your energy flows:

Optimising self-consumption with batteries

Combined with a Sofar ESI inverter and a Sofar BTS 5K battery (4.75 kWh usable), the DDSU666 meter enables intelligent management of your energy:

• Priority to self-consumption: solar energy feeds your direct consumption first.
• Automatic storage of surpluses: excess energy charges your battery for later use
• Injection limit: Set a zero export or grid injection limit
• Intelligent discharge: The battery discharges when solar production is insufficient
• Off-peak optimisation: schedule battery charging on the grid during off-peak hours

Quick and easy installation

The DDSU666 meter connects directly to your existing single-phase electrical installation. Its plug-and-play design makes installation easy:

• Single-phase connection: Simple 230V phase/neutral wiring
• Automatic communication: Automatic detection by the Sofar ESI inverter
• Configuration via SolarMan: Remote parameter setting from the mobile application
• Compact installation: Small dimensions for panel mounting
