Atmoce Ecosystem - Compatibility & Integration
The Atmoce MI-450 Microinverter is engineered for seamless integration within the Atmoce AC-coupled ecosystem. Its high-frequency Power Line Communication (PLC) ensures plug-and-play synchronization with the following core components:
- Atmoce M-Battery 7kWh (MS-7K-U): Integrates directly via the AC bus. This pairing facilitates a safe, extra-low-voltage (<30V DC) storage solution with a scalable capacity of up to 126kWh.
- Atmoce M-Combiner Pro Single Phase: Serves as the central management hub for single-phase arrays. It consolidates MI-450 PV strings and battery storage, providing rapid UPS-level backup switching (<10ms) and comprehensive EMS control.
- Atmoce M-Combiner Pro Three Phase: Enables balanced three-phase distribution for larger MI-450 deployments. It manages phase-level monitoring and ensures system stability through unified data aggregation to the ATMOZEN cloud platform.
Technical Synergy:
- Communication: Robust PLC protocol eliminates the need for additional signal wiring.
- Grid Management: Supports coordinated Zero Export and Time-of-Use (TOU) via the M-Combiner interface.
- Safety: Full system compliance with rapid shutdown requirements and low-voltage DC architecture.
