The Enphase Envoy-S Metered is the communication gateway and control centre for Enphase microinverter systems, enabling comprehensive energy management for both single-phase and multi-phase (three-phase) installations. Bridging communications from rooftop microinverters to the Enphase App and the Enlighten Cloud, Enphase Envoy-S Metered provides real-time solar generation and energy consumption monitoring, allowing installers and homeowners to track performance, receive remote software updates, and optimise energy use.

• Full Energy Visibility: Monitors solar production and whole-home consumption with included or optional current transformers (CTs).
• Remote Monitoring & Control: Enables web-based system insights, alerts, and diagnostics through the Enphase App and Enlighten portal.
• Bidirectional Communication: Supports remote upgrades and load management for smart grid participation and future expandability.
• Flexible Networking: Connects via integrated Wi-Fi, Ethernet, or optional Enphase Mobile Connect cellular modem.
• Supports Export Limiting: Enables zero-export and power feed-in limitation for compliance with grid regulations.
• High System Capacity: Supports up to 600 compatible microinverters per Envoy-S.
• Easy Setup: Configurable via the Enphase Installer Toolkit mobile app.
• Reliable System Design: Hardwired device with indoor or protected outdoor mounting options. Backed by a 5-year warranty.
